Abstract
Control the method for soybean cyst nematode, it relates to a kind of method of controlling soybean parasitosis evil. The present invention relies on chemical pesticide seed dressing, the technical problem of contaminated soil and environment in order to solve existing control soybean cyst nematode. The method of controlling soybean cyst nematode is as follows: the mode that adopts pearl millet and soybean crop rotation in 2 years. The method of control soybean cyst nematode of the present invention can be controlled cyst, ovum and the second instar larvae quantity of SCN in soyabean field effectively, prevent from using soil and the environmental pollution that chemical pesticide causes simultaneously, adopt after the inventive method plantation pearl millet at 6 years continuous cropping soils of soybean, in autumn soil, cyst is compared with having reduced 31.1%-100% spring; Adopt after the inventive method plantation pearl millet at 7 years continuous cropping soils of soybean, in autumn soil, cyst is compared with having reduced 64.4%-100% spring. The invention belongs to the diseases and pests of agronomic crop field of controlling.
Description
Technical field
The present invention relates to a kind of method of controlling soybean cyst nematode evil.
Background technology
Soybean cyst nematode is one of the most serious disease of soybean, and this disease is by soybean cyst nematode Heterodera glycines (HeteroderaglycinesIchinohe) due to infecting, its sick feature is that distribution is wide, harm is heavy, is a kind of extremely difficult soil-borne disease of preventing and treating. Soybean born of the same parentsCyst mematode causes very large economic loss every year in global Soybean production, and especially after Soybean Cropping, harm is more serious, orderFront is mainly to use chemical agent seed dressing in China to the control of this disease, but using of chemical pesticide causes soil and environment dirtDye, to people and animals and natural environment safety, in production, most economical effective control method is plantation disease-resistant variety, but China is largeThe disease-resistant variety that beans main producing region is bred as is less, is difficult to reach large-area applying.
Pearl millet, formal name used at school Pennisetumglaucum, (L.), also claims pearl millet, cat tail grain or cattailmillet, is annual herb,Can grain and feed dual-purpose. Be valuable forage crop, in seed, ratio of crude protein corn is high by 8%～60%, lysine and eggPropylhomoserin is higher by 40% than corn, and threonine, also higher than corn, can be domestic animal the energy suitable with corn is provided, and is the energy of high-qualityFeed. After soybean producing region adopts successive soybean cropping, plant pearl millet, can alleviate soybean cyst nematode Heterodera glycines damage to soybean, pearlGrain is as the good forage grass and feed of domestic animal, and this technology also can promote animal husbandry in agricultural area development.
Summary of the invention
The object of the invention is to rely on chemical pesticide seed dressing, contaminated soil and ring in order to solve existing control soybean cyst nematodeThe technical problem in border, provides a kind of method of controlling soybean cyst nematode.
The method of controlling soybean cyst nematode is as follows: the mode that adopts pearl millet and soybean crop rotation in 2 years;
Wherein the implantation methods of pearl millet is realized according to the following steps:
One, plant pearl millet, application rate 1.5-2kg/667m season at crop-planting2(mu), the field density of keeping a full stand of seedings is 32-40Ten thousand strain/hectares;
Two, apply fertilizer, farming and cultivation management;
Three, cradle 1 time in early July, cradle for the second time in the crop harvesting phase and carry out, pearl millet Cutting is 1-2Inferior.
The kind of the pearl millet described in step 1 is CFPM-101.
In step 3, pearl millet Cutting is 1-2 time.
The method of control soybean cyst nematode of the present invention can be controlled cyst, the ovum of SCN in soyabean field effectivelyWith second instar larvae quantity, especially reduce SCN worm source, successive soybean cropping field radix, alleviate SCN large to Second Year plantationThe harm of beans. Prevent from using soil and the environmental pollution that chemical pesticide causes simultaneously, this method to person poultry harmless, safely, makeWith convenient, production cost is low, pearl millet is the good feed of domestic animal, also can promote animal husbandry development. In soybean continuous cropping in 6 yearsSoil adopts after the inventive method plantation pearl millet, and in autumn soil, cyst is compared with having reduced 31.1%-100% spring; Soybean7 years continuous cropping soils adopt after the inventive method plantation pearl millets, and in autumn soil, cyst is compared with having reduced 64.4%-100% spring.
Detailed description of the invention
Technical solution of the present invention is not limited to following cited detailed description of the invention, also comprise between each detailed description of the invention arbitrarilyCombination.
Detailed description of the invention one: the method for present embodiment control soybean cyst nematode is as follows: adopt pearl millet and soybean twoThe mode of year crop rotation;
Wherein the implantation methods of pearl millet is realized according to the following steps:
One, plant pearl millet, application rate 1.5-2kg/667m in planting season2(mu), the field density of keeping a full stand of seedings is 32-40 ten thousand strains/ hectare;
Two, apply fertilizer, farming and cultivation management;
Three, cradle 1 time in early July, cradle for the second time in the crop harvesting phase and carry out, pearl millet Cutting is 1-2Inferior.
Detailed description of the invention two: what present embodiment was different from detailed description of the invention one is the product of the pearl millet described in step 1Planting is CFPM-101. Other is identical with detailed description of the invention one.
Detailed description of the invention three: what present embodiment was different from one of detailed description of the invention one or two is that in step 3, pearl millet is cutCutting number of times is 2 times. Other is identical with one of detailed description of the invention one or two.
Adopt following experimental verification effect of the present invention:
Experiment one:
Experiment adopts field test method to carry out, and spring is soil sampling in 6 years continuous cropping soils of soybean, centrifugal floating through sucroseMethod record pearl millet cradle once, twice, three times and contrast 4 trial zone soybean cyst nematode Heterodera glycines cyst quantity be respectively60/100 grams soil, 56/100 grams soil, 63/100 grams soil and 80/100 grams soil, planting respectively in the fall OctoberPlant after pearl millet cradle once, 4 trial zone soil samplings of twice, three times and contrast record the cyst number of soybean cyst nematode Heterodera glycinesAmount is respectively in 2/100 grams soil, 1/100 grams soil, 0/100 grams soil and 158/100 grams soil, and result shows plantsPlant after pearl millet in soil in autumn cyst compared with having reduced 96.7%-100% spring.
Experiment two:
Experiment adopts field test method to carry out, and spring is soil sampling in 7 years continuous cropping soils of soybean, centrifugal floating through sucroseMethod record pearl millet cradle once, twice, three times and contrast 4 trial zone soybean cyst nematode Heterodera glycines cyst quantity be respectively 4Individual/100 gram soil, 3/100 grams soil, 5/100 grams soil and 5/100 grams soil, October is respectively 4 examinations in the fallTest district soil sampling and measure the cyst quantity of soybean cyst nematode Heterodera glycines, result be after plantation pearl millet, cradle once, twice, three timesThe cyst quantity of nematode is 0/100 grams soil, and the cyst quantity of check plot nematode is 5/100 grams soil, and result showsAfter 7 years continuous cropping soils of soybean plantation pearl millet in autumn soil cyst compared with having reduced 100% spring.
