Seed treatment method for improving continuous cropping tolerance capacity of soybeans

Abstract

The invention discloses a seed treatment method for improving the continuous cropping tolerance capacity of soybeans.The method comprises the following steps that soybean seeds of which seed husks are free of breakage, disease spots and worm damage are selected; a treatment solution is prepared, wherein the treatment solution is prepared from 0-0.004% of S3307, 0.005%-0.04% of brassinolide, 0-8% of fosthiazate, 1%-2.5% of trace-element components, 3%-6% of additives and the balance water; the soybean seeds and the treatment solution are subjected to the processes of thorough mixing, seed dressing and coating and then air-dried for use.According to the seed treatment method for improving the continuous cropping tolerance capacity of the soybeans, the stem thickness, leaf area, root volume, dry matter weight and dry weight of root nodules of soybean seedlings under the continuous cropping condition can be increased, and the total chlorophyll content and resistance physiological indexes can be improved.In this way, the seed treatment method has the advantages of improving physiological metabolism, increasing the chlorophyll content, enhancing the photosynthetic performance, nitrogen fixing capacity and stress resistance, reducing seedling stage diseases and pests and comprehensively promoting the continuous cropping tolerance capacity of the soybeans and being friendly to environment.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and relates to a seed treatment method for improving the ability of continuous cropping tolerance of soybeans. Background technique [0002] Soybean, as an agricultural product with both grain, oil and feed, and an important industrial raw material, has always been one of the crops that cannot be ignored in all countries in the world. Therefore, doing a good job in soybean agricultural production is related to the national economy and people's livelihood. However, due to the regionalization and intensification of agricultural production, in the current soybean production, continuous cropping has become an important bottleneck restricting the improvement of soybean yield and quality, that is, the key problem. In particular, Northeast my country and Inner Mongolia are the main production areas of high-quality soybeans and important commodity soybean production areas in China. The country has ca...

Problems solved by technology

However, in practical application, it is found that the resources of resistant varieties are scarce and the yield is low, while conventional seed coating agents usually contain the highly toxic and high-residue pesticide carbofuran, and have no obvious effect on improving soybean continuous cropping tolerance and regulating soybean seedling growth. Under the guidance of prevention and control policies, the use of these agents will be gradually restricted, so there is an urgent need for new technologies or methods in production
