摘要

减少蔬菜种植中化学品的使用是一项环保的种植技术,有望减少对环境的负面影响。减少种植中化学物质的努力之一是使用植物根部的细菌作为植物生长促进剂或生物杀虫剂。本研究旨在确定竹子和豆科根中有潜力作为植物生长促进剂的内生细菌的数量。以竹子、柠檬草和含羞草为试材,研制了植物生长促进根际细菌(PGPR)发酵剂。此外,还将其应用于蔬菜种植(大白菜、番茄、胡萝卜和绿芥菜/caisim),以根据PGPR应用的结果与传统农民的结果进行比较,确定蔬菜的物理特性。本研究采用2个因素的析因随机区组设计。第一个因素是所使用的植物根,而第二个因素是植物根在水中浸泡的长度,即72、96、120小时。将PGPR启动器分析结果中的数据制成表格,然后进行描述性讨论。对于来自使用PGPR的种植结果的蔬菜数据,与来自传统农民结果的蔬菜进行比较。通过实验室分析,得出浸泡时间为72小时的竹根样品中的微生物总数高于其他样品,即8.49×106cfu ml-1;Mimosa Pudica Linn、竹子、柠檬草、商业PGPR(来自中爪哇农民)根的PGPR样品的pH范围为3.0至6.7;而总溶解固体含量在0.2%至2.6%之间。从PGPR处理和未处理的植物生长图来看,两者略有差异,没有太大的增加或减少。在使用PGPR处理的番茄中,植物生长高于不使用PGPR的番茄,而在大白菜和菜心中,PGPR处理和不使用PGPR的番茄的生长几乎相同。对于胡萝卜,可以看出,有PGPR处理的植物生长低于没有PGPR处理。应用PGPR对大白菜、菜心、番茄和胡萝卜的质地、亮度水平和总溶解固体进行了分析,其特征与传统农民的结果几乎相同。通过观察这些结果,希望在未来的栽培创新中,利用根部周围的细菌,是环境友好的栽培应用之一,并开始减少栽培中化学品的使用。

Cultivation Innovations of Growth Promoting Bacteria and the Characteristics of Several Vegetables
Reducing the use of chemicals in vegetable cultivation is an environmentally friendly cultivation technology that is expected to reduce negative impacts on the environment. One of the efforts to reduce chemicals in cultivation is to use bacteria that live in plant roots as plant growth promoters or biopesticides. This study aims to determine the number of endophytic bacteria from bamboo and leguminosae roots that have the potential as plant growth promoting agents. The making of plant growth-promoting rhizobacteria (PGPR) starter which was carried out in this study used the roots of bamboo, lemongrass and Mimosa Pudica Linn. Furthermore, it is applied to vegetable cultivation (Chinese cabbage, tomato, carrot and green mustard/caisim) to determine the physical characteristics of vegetables from the result of PGPR application compared to results from conventional farmers. This study used a factorial randomized block design with 2 factors. The first factor is the plant roots used, while the second factor is the length of the plant roots soaking in water, namely 72, 96, 120 hours. The data from the PGPR starter analysis results are made into a table, then a descriptive discussion is carried out. For vegetable data from the cultivation results using PGPR compared to vegetable from conventional farmer results. Based on laboratory analysis, obtained the total microbes in samples from bamboo roots with a soaking time of 72 hours were higher than the other samples, namely 8.49 x 106 cfu ml-1; pH in samples of PGPR from the roots of Mimosa Pudica Linn, bamboo, lemongrass, commercial PGPR (from Central Java farmers) ranged from 3.0 to 6.7; while the total dissolved solids content ranged from 0.2 to 2.6%. Based on the graph of plant growth in the PGPR treatment and with no treatment, there is a slight difference, not much increase or decrease. In tomatoes with PGPR treatment, plant growth was higher than without the use of PGPR, while for Chinese cabbage and caisim the growth was almost the same between PGPR treatment and without PGPR. For carrots, it was seen that with PGPR treatment, plant growth was lower than without PGPR. The results of the analysis of texture, brightness level and total dissolved solids in Chinese cabbage, caisim, tomatoes and carrots with PGPR application, the characteristics are almost the same as the results of conventional farmers. By looking at these results, it is hoped that in the future cultivation innovation by utilizing bacteria around the roots, is one of the environmentally friendly cultivation applications and begins to reduce the use of chemicals in cultivation.
