Method for treating low temperature resistance drought-resistant seeds

Abstract

The invention provides a method for treating low temperature resistance drought-resistant seeds, which comprises steps: crop seeds are placed in a water bath kettle to have a water bath treatment, the outer surfaces of the crop seeds are coated through a seed treating agent after being treated in water bath, and the coated seeds are placed into an air dry oven to dry. A low temperature resistance drought-resistant seed treating agent has excellent low temperature resistance drought-resistant ability in a seedling emergence stage or a seedling stage of crops, and has the advantages that the low temperature resistance drought-resistant seed treating agent improves crop seedling emergence and germination potential. The method for preparing the low temperature resistance drought-resistant seed treating agent is wide in source of raw materials formula and low in price, is easy to be generalized in large area during producing. The low temperature resistance drought-resistant seed treating agent has obvious stress tolerance effect to the crop seedling stage in low temperature dry conditions.

Description

technical field [0001] The invention belongs to the field of plant growth regulators, and in particular relates to a treatment method for low-temperature and drought-resistant seeds. Background technique [0002] Low temperature and drought after planting will affect seed germination, slow down the germination process, reduce germination potential and germination rate, delay emergence and reduce seedling vigor; , so that the crops are vulnerable to low temperature damage at the seedling stage, the growth and development are affected, and the germination potential and germination rate of the seeds are significantly reduced, and the reduction in the germination potential is greater than the germination rate; when the seeds encounter low temperature after germination, the growth of plant vegetative bodies will be significantly inhibited and developmental process, the degree of inhibition increases with the prolongation of low temperature duration. Studies have shown that SOD en...

Problems solved by technology

[0003] Seed treatment agent is a kind of pesticide used for seed surface treatment. The active ingredients are mainly insecticides or fungicides. At present, seeds are coated with seeds before sowing, which can prevent and control crop pests and rodents in the seedling stage. Improving the survival rate of seedlings, etc. Many seed treatment agents and coating agents currently in production can improve seed resistance to a certain extent, but most of them focus on the effect of seed disease resistance and insect resistance, which is helpful for improving seedlings under low temperature and drought conditions. Therefore, it is of great significance to enhance the ability of crops to resist low temperature and drought at the seedling stage to ensure crop resistance, seedling protection, high yield and stable yield.
