The consumption of vegetables is one of the most important pathways for heavy elements to harm human health. Direct deposition of contaminants from the atmosphere onto plant surfaces and accumulation of heavy elements in flooded arable soil are of great concern because of the potential health risk to the local population. Thus, the present study was carried out to analyse distribution and soil-plant transfer of Pb, Cd, As, Co, Cr, Ni, Cu, Mn and Fe in potato, carrot, celery, parsnip and onion in order to evaluate their potential effects on human health. Total content of heavy elements in 26 vegetable samples collected from different flooded fields was analysed by atomic absorption spectrometry with a graphite furnace (AASGF) after microwave digestion of the analysed samples. Average concentrations of lead (Pb) and cadmium (Cd) in some of the investigated vegetable samples were higher than maximum allowable concentrations set by EC/Serbian regulation. On the other hand, arsenic (As) was not detected in any of the analysed samples. Accumulation and translocation of analysed elements were varied from element to element as well as among selected vegetable crops. The results showed that the parsnip had highest uptake for the most analysed elements (Fe (107 mg/kg) ˃ Mn (6.98 mg/kg)˃ Cu (1.94 mg/kg)˃Ni (0.34 mg/kg)˃ Pb (0.13 mg/kg) compared with the other investigated crops. The bioaccumulation factor (BA) for analysed elements in different vegetables was found in order of Cd (0.08)˃Fe(0.07)˃Cu (0.06)˃Pb (0.01)=Ni˃Mn (0.001), indicating that analysed crops are categorized as excluder (BA<1). The total health risk associated with the consumption of investigated vegetables grown in studied flooded arable soil was assessed using target hazard quotient (THQ). The THQ values estimated for investigated crops were notably below the safe limit of 1, except for Mn (2.10) and Fe (11.65).
食用蔬菜是重元素危害人体健康的重要途径之一。污染物从大气中直接沉积到植物表面以及重元素在被淹耕地土壤中的积累引起了极大的关注,因为这对当地居民的健康构成了潜在的风险。因此,本研究旨在分析马铃薯、胡萝卜、芹菜、防风草和洋葱中Pb、Cd、As、Co、Cr、Ni、Cu、Mn和Fe的分布和土壤-植物转移,以评价它们对人体健康的潜在影响。本文采用石墨炉原子吸收光谱法,对26份不同淹水农田蔬菜样品进行微波消解后的总重元素含量分析。部分蔬菜样品中铅(Pb)和镉(Cd)的平均浓度高于欧盟/塞尔维亚法规规定的最大允许浓度。另一方面,砷(As)未在任何分析样本中检测到。所分析元素的积累和转运在不同元素之间以及所选蔬菜作物之间存在差异。结果表明,与其他研究作物相比,防风草对分析元素(Fe (107 mg/kg)、Mn (6.98 mg/kg)、Cu (1.94 mg/kg)、Ni (0.34 mg/kg)、Pb (0.13 mg/kg)的吸收量最高。不同蔬菜中所分析元素的生物积累因子(BA)大小顺序为Cd(0.08)→Fe(0.07)→Cu(0.06)→Pb(0.01)→Ni→Mn(0.001),表明所分析的作物属于排除因子(BA<1)。采用目标危害商(THQ)评价了在被淹耕地土壤中食用蔬菜的总体健康风险。除锰(2.10)和铁(11.65)外,所有作物的THQ值均低于安全限值1。

The aim of the paper is to raise, direct and encourage awareness of the importance of biomass in energy production, as well as to present various possibilities of its use. Increasing demands for energy and growing environmental issues impose the need for energy production from renewable resources. Fossil fuel reserves are finite and their deficit is projected for the coming period. Biogas is one of the renewable resources. The said gas consists of a large amount of methane gas produced by fermenting organic substances from biomass, manure or any other biodegradable material in anaerobic conditions. Electricity production from renewable resources on farms needs to meet numerous conditions, such as environmental protection, bio-safety and animal welfare, as well as a series of technical, organisational, construction, manufacturing and economic requirements imposed by this kind of production. The Lazar Company Ltd. from the town of Blace owns a farm with 600 dairy cows, a dairy which processes 60 000 litres of milk per day, as well as an energy production plant based on biogas, with the capacity of 1mW/hour. In addition, special attention is paid to organic farming, where biomass is said to have multiple applications in energy production in the context of a long-term development trends of certain industries.
该文件的目的是提高、指导和鼓励对生物质在能源生产中的重要性的认识,并提出利用它的各种可能性。日益增长的能源需求和日益严重的环境问题迫使人们需要利用可再生资源生产能源。化石燃料储量是有限的,预计未来一段时间将出现短缺。沼气是一种可再生资源。所述气体由在厌氧条件下发酵生物质、粪便或任何其他可生物降解材料中的有机物质产生的大量甲烷气体组成。在农场利用可再生资源生产电力需要满足许多条件,如环境保护、生物安全和动物福利,以及这种生产所带来的一系列技术、组织、建设、制造和经济要求。来自Blace镇的Lazar有限公司拥有一个拥有600头奶牛的农场,一个每天处理6万升牛奶的奶牛场,以及一个以沼气为基础的能源生产工厂,产能为每小时1兆瓦。此外,特别关注有机农业,在某些行业的长期发展趋势的背景下,据说生物质在能源生产中有多种应用。

INFLUENCE OF PRECIPITATION UPON DRAINAGE DISCHARGE IN TWO DIFFERENT CLIMATIC REGIONS 两个不同气候区降水对排水的影响
Pub Date : 1900-01-01 DOI: 10.55302/jafes18721122m

The goal of three-year investigations was to determine the influence of precipitation upon the drainage discharge in two different climatic regions (Croatia and Lithuania) at two different pipe drainage spacing in each region (first region with 15 m and 20 m drainage spacing and second region with 12 m and 24 m drainage spacing), to calculate the soil water balance according Thornthwaite's method and compare the measured drainage discharge and the calculated surplus of water in soil. Investigations were carried out at the experimental amelioration sites in the central Sava River Valley (Croatia) on hydroameliorated Gleyic Podzoluvisol soil and in Middle part of Lithuania on hydroameliorated Hypogleyic Luvisol soil in the period 2009 - 2011. The research results showed that the drainage discharge and its duration depended on the amount and distribution of the precipitation during the study period. There isn't difference in the total drainage discharge between the tested drainpipe spacing in each investigation year, but there are differences in the duration of the drainage discharge both on an annual scale and depending on drainpipe spacing. In each year, the duration of drainage discharge was smaller at the 12-15 m drainpipe spacing than at the 18-20 m drainpipe spacing. The calculated surplus of water followed the monthly amounts of precipitation, but in all years was higher than the drainage discharge. The 12 to 15 m pipe spacing is more efficient for draining the surplus water from drained soils, since the surplus of water from soil is drained in a shorter period of time and better water-air relationships in soil are created faster, which is a prerequisite for timely application of agricultural management practices on hydroameliorated arable areas.
为期三年的调查目标是确定降水对两个不同气候区(克罗地亚和立陶宛)在每个区域的两个不同管道排水间距(第一个区域为15 m和20 m排水间距,第二个区域为12 m和24 m排水间距)的排水流量的影响,根据Thornthwaite的方法计算土壤水分平衡,并将测量的排水流量与计算的土壤剩余水量进行比较。2009 - 2011年,在克罗地亚萨瓦河流域中部的水化改良Gleyic podzolvisol土壤试验点和立陶宛中部的水化改良Hypogleyic Luvisol土壤试验点进行了调查。研究结果表明,流域流量及其持续时间取决于研究期降水的数量和分布。各调查年度各试验排水管间距的排水总量没有差异,但排水持续时间在年度尺度和不同排水管间距上存在差异。各年份排水管间距为12 ~ 15 m时,排水持续时间小于排水管间距为18 ~ 20 m时。计算的富余水量随月降水量变化,但历年均大于排水流量。12 ~ 15 m管距排水土壤富余水效率更高,因为土壤富余水在更短的时间内被排干,土壤中形成更好的水气关系更快,这是及时在水化改良耕地上实施农业管理措施的前提条件。

Technological characters determine the so-called technological - commercial quality of tobacco and tobacco products during fabrication. Three-year trials were performed with variety YK 7-4/2 (check) and three Basmak varieties - MK-1, MB-2 and MB-3. The trial was designed in randomized blocks with five replications. The aim of investigation was to determine water retention capacity, density, filling capacity and fractional composition of tobacco by insertions. WRC was determined by the method of ( Boceski, 2003), filling capacity (cm 3 /g) and density (g/cm 3 ) were determined using the Borgwaldt densimeter by the method of Shuto (1972) and fractional composition by the method of Dorahova and Dikker. During the three years of investigation, WRC ranged from 16.87% in the lower leaf of variety MB-2 to 23.70% in the middle leaf of MB-3, which proves that the investigated varieties of Basmak tobacco have higher WRC compared to the check. The lowest density by insertions and years and the highest filling capacity was recorded in the middle leaf of MB-2 in 2009 (0.195 g/cm 3 ). In the three years of investigation, the lowest average density was recorded in lower leaves of the variety MB-3 (0.213 g/cm 3 ) and the highest in top leaves of the check variety YK 7-4/2 (0.303 g/cm 3 ). The filling capacity was the highest (5.13 cm 3 /g ) in middle leaves of the variety MB-2 and the lowest (2.91 cm 3 /g) in undertop leaves of the variety MB-3 in 2009. In average, the lowest positive fraction was measured in lower leaves of the variety MB-2 (78.99%) and the highest in middle leaves of the variety MB-3 (93.23%), while the negative fraction ranges from 10.16% in MB-3 to 21.11% in the check variety JK 7-4/2. The data obtained show that the characteristics of the investigated Basmak varieties are typical for the oriental tobacco. presented by insertions: water retention capacity, positive and negative fraction, density and filling capacity. Physical characters of tobacco are particularly important in manufacture of final products.
工艺特性决定了烟草和烟草制品在加工过程中的所谓技术-商业质量。品种YK 7-4/2(检查)和三个Basmak品种MK-1、MB-2和MB-3进行了为期三年的试验。试验设计为随机分组,每组5个重复。研究的目的是确定烟叶的保水性、密度、填充量和分数成分。WRC采用(Boceski, 2003)法测定,填充容量(cm 3 /g)和密度(g/cm 3)采用boorgwaldt密度计,Shuto(1972)法测定,Dorahova和Dikker分式成分法测定。在3年的调查中,品种MB-2的下叶WRC值为16.87%,MB-3的中叶WRC值为23.70%,表明被调查品种Basmak烟草WRC值高于对照。2009年MB-2中叶灌浆量最高,灌丛密度最低,为0.195 g/ cm3;在3年的调查中,MB-3的下叶平均密度最低(0.213 g/cm 3),对照品种YK 7-4/2的上叶平均密度最高(0.303 g/cm 3)。2009年,MB-2的中部叶片灌浆量最高(5.13 cm 3 /g),下部叶片灌浆量最低(2.91 cm 3 /g)。其中,MB-2的下叶阳性比例最低(78.99%),MB-3的中叶阳性比例最高(93.23%),而对照品种JK 7-4/2的阴性比例在10.16% ~ 21.11%之间。结果表明,所调查的巴斯马克品种具有典型的东方烟草特征。由插入表示:保水能力,正负分数,密度和填充能力。烟草的物理特性在最终产品的制造中尤为重要。

As a result of the use of the following elements nitrogen (N), sulphur (S) and boron (B) quantitative properties of two genotypes of oilseed rape Brassica napus L., Zorica (variety) and Rohan (hybrid) were determined. The main purpose of the study was determination of the production mode, set in both genotypes of oilseed rape versus managing various nutrients. An experiment was set in the Skopje region, on total experimental area of 650m. For this purpose, the following combinations of fertilizers were used: N1 with 110 kg/ha nitrogen, N2 with 150 kg/ha nitrogen, S1 with 30 kg/ha sulphur, S2 with 70 kg/ha sulphur, B1 with 1.0 kg/ha boron, and B2 with 2.0 kg/ha boron (at spring time, foliar application) versus standard variant: N:P:K in the ratio 10:20:30 (N 50kg/ha, 90 kg/ha P2O5 and 180 kg/ha K2O) used in autumn. During the experiment the following parameters were monitored: height of plants (cm), number of branches per plant, number of pods per plant, length of pod (cm), number of seeds in the silique, and seed yield (t/ha). From the combinations of nutrients and variations that have been set in terms of genotypes, the results of yield showed statistical significance at level of 0.05 from variants N2PK, N2PK+S2+B2 in variety Zorica and N1PK+S1+B1 in the hybrid Rohan.

The kiwifruit is originated Southeast Asia whose production and consumption is increased each day. The production quantity has reached 3.447.605 tonnes around the world. It is also important to protect the quality of kiwifruit which has a high vitamin C, in the postharvest period. One of the most important problems of kiwifruit is infections originated by fungus during storage. The most common fungal disease in kiwifruit storage is Botrytis cinerea . The first symptom is seen after a few week storage. Because the pathogen can develope in the cold storage conditions, it causes decay and serious economical damage. Although the chemical methods is used to prevent this disease, with the increasing consumer awareness and due to caused the risk both environmental and human health, the tendency towards non-chemical methods of combat has been increased. The aim of this study is to compile the studies on non-chemical struggle methods used in Botrytis cinerea struggle. It was found that the most common non-chemical treatments are curing, heat applications, ultraviolet light applications, gamma radiation applications, ozone application and essential oil applications. Because these physical methods are not risk to the human health, it will guide for future research.
猕猴桃原产于东南亚,其产量和消费量日益增加。全球产量已达3.447.605吨。猕猴桃富含维生素C,在采后保护其品质也很重要。猕猴桃贮藏过程中的真菌侵染是猕猴桃最重要的问题之一。猕猴桃储藏中最常见的真菌病害是葡萄孢菌病。第一个症状在几周后出现。由于病原菌可以在冷藏条件下生长,造成腐烂和严重的经济损失。虽然使用了化学方法来预防这种疾病,但随着消费者意识的提高以及对环境和人类健康造成的风险,采用非化学方法进行战斗的趋势有所增加。本研究的目的是对灰葡萄孢非化学斗争方法的研究进行综述。研究发现,最常见的非化学处理是固化、热应用、紫外线应用、伽马辐射应用、臭氧应用和精油应用。由于这些物理方法对人体健康没有危害,对今后的研究具有指导意义。

The goal of this study was to examine the effect of seven cherry rootstocks (‘Gisela 5’, ‘Gisela 6’, ‘CAB 6P’, ‘Alkavo 2’, ‘F 12/1’, ‘MaxMa14’ and ‘MaxMa 60’) on the growth and productivity of ‘Summit’ sweet cherry cultivar. The trees were planted in the spring of 2008 at distances of 4.0 x 3.0 m, shaped in freely growing crown and irrigated by spraying over the crowns. Tree vigour (trunk cross-sectional area and crown volume), yield, yield efficiency and fruit quality were recorded each year in the period 2008-2016. The results clearly showed the influence of rootstocks on the trees growth. Nine years after planting the most vigorous rootstock was ‘MaxMa 60’ and the weakest were ‘Gisela 5’ and ‘Gisela 6’. The highest 4-year cumulative yield per tree was obtained with ‘MaxMa 60’, followed by ‘CAB 6P’ and ‘MaxMa 14’. Rootstocks ‘Gisela 5’ and ‘Gisela 6’ negatively influenced yield and fruit size.
本研究的目的是研究7个樱桃砧木(‘吉塞拉5号’、‘吉塞拉6号’、‘CAB 6P’、‘Alkavo 2号’、‘F 12/1’、‘MaxMa14号’和‘maxma60号’)对‘顶峰’甜樱桃品种生长和产量的影响。这些树在2008年春天种植,间距为4.0 x 3.0米,形成自由生长的树冠,并通过树冠喷洒灌溉。在2008-2016年期间,每年记录树木活力(树干横截面积和树冠体积)、产量、产量效率和果实质量。结果清楚地显示了砧木对树木生长的影响。种植9年后,最具活力的砧木是‘MaxMa 60’,最弱的是‘Gisela 5’和‘Gisela 6’。4年单株累积产量最高的品种是‘maxma60’,其次是‘CAB 6P’和‘maxma14’。砧木‘吉塞拉5号’和‘吉塞拉6号’对产量和果实大小有负向影响。
