As shown in the agricultural development experience of various countries in the world, the agricultural operating entity has become an effective means to increase the agricultural production efficiency and establish a scientific management model. Promoting the continuous improvement of the modern agricultural management system is not only an important means for solving the three rural issues in China, but also a key measure to enhance China's agricultural competitiveness. This paper introduced the basic situation of agricultural operating entities in Japan and Germany, summarized their advanced experience, and finally came up with feasible recommendations for enhancing the competitive advantages of agricultural operating entities in China.

[Objectives] This study aimed to study the effect of ethephon treatment on the growth of two main grape varieties Kyoho and Shine-Muscat. [Methods] Two-year-old Kyoho and Shine-Muscat grape plants transplanted in the film-covered steel-framed greenhouse were used as the test materials. They were pruned horizontally and linearly. In the late growth period, the new shoots were sprayed with ethephon (1 500×). During the germination period, 10 plants were randomly selected for each variety to investigate the germination situation. Before flowering, 20 new shoots with uniform growth were randomly selected for each variety to investigate the growth. During the fruit maturity period, 10 clusters of fruits were randomly selected for each variety to determine the related indices of fruit quality. [Results] After the treatment with ethephon, the germination, new shoot growth and fruit quality differed between the two varieties. Overall, the thickness of main stem, main vine and new shoot of Shine-Muscat was greater than that of Kyoho, and the length of new shoot of Kyoho was significantly greater than that of Shine-Muscat. [Conclusions] The growth of Shine-Muscat was more robust. There was little difference in the ear weight of natural fruit setting between the two varieties. Shine-Muscat showed high sugar and low acid contents than Kyoho.

With the rapid development of China’s urbanization process, people put forward higher requirements for the efficient use of limited land resources. Facing the huge pressure brought by factors such as land, transportation and environment, the means of transportation on the ground have long been unable to meet the needs of people in modern cities. Metro is favored by people because of its high speed, stability and large capacity, and has become the best choice to relieve congestion in the public transportation system. How to efficiently use land resources while constructing urban metro systems? This article sorts out the current status of commercial construction in Nanchang metros to study the application value of commercial complex in the metro stations of Nanchang, so as to provide some useful references for related theoretical research.

[Objectives] This study aimed to determine the volatile components in Santalum album linn and gradually clarify the aroma composition of S. album linn. [Methods] Solid-phase microextraction method was used to obtain the volatile components of S. album linn. The aroma components were analyzed by gas chromatography-mass spectrometry and their relative contents were calculated using the area normalization method. [Results] In a dry state at room temperature, 39 chemical components were identified from S. album linn, mainly olefins (91.15%), alkanes (3.00%), alcohols (2.56%), esters (2.19%), ketones (0.55%), aldehydes (0.41%) and heterocyclics (0.14%). [Conclusions] This method has the advantages of low sample consumption, easy operation, rapid identification of aroma components and high sensitivity, and can effectively separate and determine volatile components in S. album linn, realizing the rapid identification of different S. album linn varieties and providing technical support for further research on Chinese medicinal materials.

he most popular farming method. [Methods] Based on the climate and soil conditions in Zhaoqing, this experiment explored the improved mode of no-tillage intercropping winter potato with citrus in the new high-ridge, wide-row and dense-plant cultivation mode citrus orchard. Taking the conventional tillage and film-mulched intercropping as the control, it studied the adaptability of intercropping, evaluated the quality, and analyzed its economic benefits. [Results] The early emergence rate of improved no-tillage intercropping cultivation was slightly higher than that of conventional tillage and film-mulched intercropping, but the difference of final emergence rate was not significant, indicating that improved no-tillage intercropping cultivation could provide excellent potato emergence environment. Under the conventional tillage and improved no-tillage intercropping cultivation mode, the change trend of the potato's plant height, main stem thickness, crown diameter and number of leaflet is the same. The change rule of the crown diameter of the film-mulched intercropping cultivation method is similar to that of the plant height, both have a large increase in the late growth stage. The potato yield of improved no-tillage intercropping cultivation were 22 747.5 kg/ha, and the proportions of potatoes of each grade were 11.85%, 35.61%, 37.63% and 14.91%, respectively. The content of dry matter, Vc, soluble protein, starch and amino acid in the main nutrients of the potato under the improved no-tillage intercropping model is not significantly different from that of the film-mulched intercropping cultivation. The changing trend of reducing sugar content showed that the reducing sugar content of no-tillage intercropping cultivation was the highest (0.466%). Through evaluating the eating characteristics of potatoes from the flavor, taste, texture and appearance after chewing, the three cultivation methods have little difference. In the no-tillage intercropping cultivation technology, the growth of potatoes consumes part of the nutrients in the soil between the rows of the citrus orchard, but it does not exerts a significant impact on the surrounding citrus trees. Compared with the film-mulched intercropping cultivation, the improved no-tillage intercropping cultivation method does not require the expense of mulched, the cost of fertilizer is low, and labor costs are saved, so a net income of 27 075 yuan/ha can be obtained. [Conclusions] From the perspective of orchard intercropping, it has achieved the effect of improving soil utilization and increasing output without reducing the edible quality of potatoes.

[Objectives] This study aimed to explore the effect of different concentrations of selenium fertilizer on the yield, selenium content and heavy metal contents of waxy maize, thereby providing reference for the scientific application of selenium fertilizer on waxy maize. [Methods] Different varieties of waxy maize (Guitiannuo 611, Guinuo 615 and Guiheinuo 609) were used as test materials. They were sprayed with different concentrations (0, 0.5, 1.0, 1.5 and 2.0 g/L) of water-soluble selenium fertilizer (Xinxibao) at the big flare stage, and the effect on the yield, selenium content and heavy metal contents of the waxy maize was analyzed. [Results] Foliar application of different concentrations of selenium fertilizer showed no significant effect on the yield and yield components of waxy maize. As the concentration of selenium fertilizer increased, the grain selenium content of different varieties of waxy maize increased. Among them, the increase of Guinuo 615 was the largest, of which the selenium content reached 0.265 mg/kg, 2.82 times that of the control (water). The cadmium and arsenic contents of different varieties of waxy maize decreased with the increase of the concentration of selenium fertilizer sprayed. Among the waxy maize varieties, the cadmium and arsenic contents of Guitiannuo 611 dropped the most significantly, up to 52.94% and 77.78%. In waxy maize, the correlation coefficients between selenium content and cadmium, arsenic contents were -0.550 9 (P<0.05) and -0.853 0 (P<0.01), respectively. [Conclusions] Spraying exogenous selenium fertilizer had no obvious effect on the yield of waxy maize. However, the increase of the concentration of exogenous selenium fertilizer could significantly increase the selenium content and reduce the cadmium and arsenic contents in grains of different varieties of waxy maize.
