Embodiment 1

[0012] Embodiment 1: Research on the prevention and control effect of the compound combination of anti-repeated cropping agent on sesame disease (preliminary test)

[0013] The tested varieties were all golden jute (black sesame, an excellent local variety in Jiangxi Province), the sowing date was July 3, 2013, and the harvest date was October 1, 2013. The test site is the test base of the Horticulture Research Institute of Jiangxi Academy of Agricultural Sciences. The soil type is sandy loam, with medium fertility and good drainage conditions. This time, sesame has been continuously cropped for 2 years, and the previous crop is rapeseed. This experiment adopts randomized block design, with 8 treatments and 3 repetitions, a total of 24 plots with an area of ​​12m 2 (2m×6m), adopt the drill method, plant 6 rows, the row spacing is 40cm, the plant spacing is about 15cm, and the density is 150,000 plants / hm 2 . Before sowing, 25kg of 45% (15:15:15) compound fertilizer was appli...

Embodiment 2

[0020] Embodiment 2: Research on the prevention and control effect of the compound combination of anti-repeated cropping agent on sesame disease (fine screening test)

[0021] The tested varieties are all golden jute, the sowing date is July 1, 2014, and the harvest date is September 29, 2014. The test site is in the test base of the Rice Research Institute of Jiangxi Academy of Agricultural Sciences. The soil type is red soil dry land with medium fertility and good drainage conditions. This time the sesame is continuously cropped for 2 years, and the previous crop is rapeseed. A total of 5 treatments (Table 3) were set up in the experiment, repeated 3 times, and a total of 15 plots were arranged in random blocks. Apply 25kg of 45% (15:15:15) compound fertilizer at one time before sowing, and manage the others as usual. Residential Area 12m 2 (2m×6m), the density is 225,000 plants / hm 2 , planted in 6 rows, with a plant spacing of 16.7cm and a row spacing of 40cm. Before ha...

Embodiment 3

[0027] Example 3: Screening test of special fertilizer formula for anti-heavy cropping

[0028] The tested variety is golden jute, sown on June 26, 2013, and harvested on September 25. The site is in the experimental base of the Horticultural Research Institute of Jiangxi Academy of Agricultural Sciences. The soil type is sandy loam with medium fertility. The sesame is continuously cropped for 2 years, and the previous crop is rapeseed. 6 treatments (Table 5) were established in the test, repeated 3 times, with a total of 18 plots, with a plot area of ​​12m 2 , arranged in random blocks. The special fertilizer for each treatment is evenly applied to the soil at one time before sowing, and the amount of special fertilizer is 1500kg / hm 2 , and other management measures are implemented as usual. The planting density is 225,000 plants / hm 2 , planted in 6 rows, with a plant spacing of 16.7cm and a row spacing of 40cm. Before harvest, 10 plants were sampled to investigate the m...

Abstract

The invention discloses a composition capable of reducing continuous cropping sesame yield loss in red soil dry land, and a method. The composition is composed of a soil fertilizer and disinfectant A,and a continuous cropping resistant agent B; the soil fertilizer and disinfectant A is composed of, by mass 42 parts of a biological organic fertilizer taking cow dung as the main ingredient, whereinthe total content of N, P, and K is equal to or larger than 6%, 12 parts of urea, 30 parts of calcium magnesium phosphate fertilizer, 10 parts of potassium chloride, 2 parts of borax, 2 parts of quintozene, and 2 parts of carbendazim, and the total content of the soil fertilizer and disinfectant A is 1500kg / hm<2>; the continuous cropping resistant agent B is composed of 6 parts of 40% flusilazoleand 40 parts of 25% kresoxim-methyl, and the water adding amount of the continuous cropping resistant agent B is controlled to be 750kg / hm<2> at seedling stage and 900kg / hm<2> at flowering phase. Thecomposition and the method are capable of improving red soil dry land sesame plantation technology, reducing continuous cropping sesame yield loss, and improving continuous cropping sesame benefit.

Description

technical field [0001] The patent of the invention relates to a composition and a method for reducing the yield loss of red soil dryland continuous cropping sesame, and belongs to the technical field of high-yield cultivation of crops. Background technique [0002] Sesame is a kind of characteristic oil crop in my country. With the enhancement of people's awareness of sesame health care, the consumption has increased significantly, the price of sesame has also increased to a certain extent, and the enthusiasm of farmers to grow sesame has increased significantly. At the same time, sesame is also a crop with serious continuous cropping obstacles. The main diseases of sesame in red soil dry land in Jiangxi are stem spot blight and bacterial wilt, especially bacterial wilt. The main reason is that during the sesame growing season (June to September), high temperature and high humidity and other weather alternately occurred, which led to the rapid reproduction of pathogenic bac...
