specific Embodiment approach 1

[0014] Specific embodiment one: the method for controlling soybean cyst nematode in this embodiment is as follows: adopt the mode of two-year rotation of pearl millet and soybean;

[0015] Wherein the implantation method of pearl millet is realized in the following steps:

[0016] 1. Plant pearl millet during the planting season, with a seeding rate of 1.5-2kg / 667m 2 (mu), the seedling density in the field is 320,000-400,000 plants / ha;

[0017] 2. Carry out fertilization, cultivation and cultivation management;

[0018] 3. Cut once in the first ten days of July, and the second cut is carried out during the harvest period of the crops. The number of cuts for pearl millet is 1-2 times.

specific Embodiment approach 2

[0019] Embodiment 2: This embodiment differs from Embodiment 1 in that the variety of pearl millet described in step 1 is CFPM-101. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0020] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that in step three, the number of times of mowing pearl millet is 2 times. Others are the same as those in the first or second embodiment.

[0021] Adopt following experiment verification effect of the present invention:

Abstract

The invention provides a method for controlling soybean cytocyst nematodosis and relates to a method for controlling soybean pests and diseases. The method for controlling the soybean cytocyst nematodosis is used for solving the technical problem that currently, the soybean cytocyst nematodosis is controlled by relying on seed dressing of chemical pesticides, and consequentially the soil and the environment are polluted. Pearl millet and soybeans are grown in a two-year crop rotation mode according to the method for controlling the soybean cytocyst nematodosis. The method for controlling the soybean cytocyst nematodosis can be used for effectively controlling the number of cytocysts, eggs and second-stage larvae of cytocyst nematodes in the soil of a soybean field and meanwhile, pollution to the soil and the environment due to application of the chemical pesticides is avoided. After the pearl millet is planted in the soil where the soy beans are planted for six years in succession, the cytocysts in the soil in autumn are reduced by 31.1%-100% compared with the cytocysts in the soil in spring. After the pearl millet is planted in the soil where the soy beans are planted for seven years in succession, the cytocysts in the soil in autumn are reduced by 64.4%-100% compared with the cytocysts in the soil in spring. The method for controlling the soybean cytocyst nematodosis belongs to the field of control on the crop diseases and the pests.

Description

technical field [0001] The invention relates to a method for controlling soybean cyst nematode disease. Background technique [0002] Soybean cyst nematode is one of the most serious diseases of soybean. The disease is caused by soybean cyst nematode (Heteroderaglycines Ichinohe). It is characterized by wide distribution and serious damage. It is an extremely difficult soil-borne disease. Soybean cyst nematode causes great economic losses in global soybean production every year, especially after continuous cropping of soybeans. At present, the prevention and treatment of this disease in my country mainly uses chemical agent seed dressing, but the application of chemical pesticides causes soil and Environmental pollution is safe for humans, animals and the natural environment. The most economical and effective control method in production is to plant disease-resistant varieties. However, there are few disease-resistant varieties bred in major soybean producing areas in my coun...
