Abstract
The invention relates to a method for controlling soybean cyst nematode, in particular to a mixture sowing method for controlling the soybean cyst nematode, solving the problems that the prior method for controlling the soybean cyst nematode is difficult to realize rotation and has low soybean yield if only planting a disease-resistant variety. The method comprises the following steps: 1, simultaneously mixing and sowing a soybean variety resisting the soybean cyst nematode and a high-yield soybean variety; 2, fertilizing, planting and managing culture; and 3, normally harvesting. The mixture sowing method for controlling the soybean cyst nematode can prevent the soybean cyst nematode from occurring, can prevent the disease resistance of the solely planted disease-resistant variety from losing, does not pollute the environment, is harmless to people and animals, has the advantages of safety, convenient use, low production cost, easy culture management and high yield and can be producedand applied in a large area.
Description
Technical field
The present invention relates to a kind of method of controlling soybean cyst nematode.
Background technology
Soybean cyst nematode is that world soybean is produced one of severe diseases, this disease is to infect the disease that causes by soybean Cyst nematode (Heterodera glycines Ichinohe), be characterized in distributing wide, harm is heavy, host range is wide, the route of transmission is many, long and extremely difficult soil-borne disease of preventing and treating of pathogene time-to-live in soil.Soybean cyst nematode causes very big economic loss every year on global agricultural, generally can make the soybean underproduction 5%～10%, and serious reaches 30%～50%, even total crop failure.The plantation soybean is 1～5 year continuously, can make the line insect population quantity in the soil increase, endanger serious, the soybean underproduction.Existing is soybean and gramineous crop crop rotation or plantation disease-resistant variety to the most economical effective control method of soybean cyst nematode.But crop rotation at present is difficult to realize that though disease-resistant variety can be controlled soybean Cyst nematode quantity in the soil effectively, alleviate harm, disease-resistant variety yielding ability poor (soybean yields is low) causes to be difficult to reach large-area applying.
Summary of the invention
The present invention seeks to exist crop rotation to be difficult to realize, plant the low problem of disease-resistant variety soybean yields merely, and a kind of hybrid sowing method of controlling soybean cyst nematode is provided for the method that solves existing control soybean cyst nematode.
The hybrid sowing method of control soybean cyst nematode is realized according to the following steps: sow simultaneously in soil after one, will resisting soybean cyst nematode soybean varieties and the mixing of high yield soybean varieties by 1: 1～1: 3 mass ratio; Two, apply fertilizer, farming and cultivation management; Three, after the soybean maturation, gather in the crops; Wherein anti-soybean cyst nematode soybean varieties is No. 5, No. 4, anti-line or anti-line in the step 1; The high yield soybean varieties is east farming 42, east farming 47, black farming 35 or black farming 44 in the step 1; The soybean planting amount is 70～80kg/ hectare in the step 1.
The hybrid sowing method that the present invention controls soybean cyst nematode can be controlled cyst, ovum and the second instar larvae quantity of Cyst nematode in the soyabean field effectively, especially reduce by the worm source radix in 1 year, the output that improves soybean is (after soybean continuous cropping soil plantation in 2 years, the miscegenation soybean yields is than the anti-soybean cyst nematode kind soybean yield-increasing 7.5%～32.1% of clean kind, and the miscegenation soybean yields increases production 22.3%～50.3% than the clean high yield soybean varieties of planting; After soybean continuous cropping soil plantation in 16 years, the miscegenation soybean yields increases production 13%～32.4% than the anti-soybean cyst nematode soybean varieties of clean kind, and the miscegenation soybean yields increases production 11.4%～30.6% than the clean soybean varieties of getting bumper crops of planting.), disease resistance forfeiture when preventing from simultaneously to plant the nematicide kind separately, free from environmental pollution, but to the person poultry harmless, safe, easy to use, production cost is low, improve output and large tracts of land production application.
