Method for enhancing toxin resistance of rice bakanae disease sterilization agent

Abstract

The invention provides a method for enhancing the toxin resistance of a rice bakanae disease sterilization agent. The method is characterized by sequentially comprising the following steps of 1, primary seed selection; 2, sprouting experiments; 3, seed insolation in sunny days: performing seed insolation for 1 to 2 days in sunny days; 4, seed selection by brine; 5, seed rinsing; 6, clean water gemmation promotion: soaking the selected seeds by clean water with the quantity capable of completely soaking the seeds, wherein the soaking time is 8 to 24 hours; 7, seed soaking by medicine: soaking the seeds subjected to gemmation promotion for sterilization for 24 to 48 hours by the sterilization agent; 8 fishing and drying: fishing and draining the sterilized seeds. A two-stage seed soaking method is used; the clean water gemmation promotion is used for realizing the resistance on the side effects of the sterilization agent; the promotion effect is achieved on the seed gemmation capabilityand seedling quality improvement; the economic properties and the practical yield are obviously improved through being compared with that of seed soaking by a single sterilization agent.

Description

technical field [0001] The invention relates to a method for soaking rice seeds, in particular to a method for soaking seeds by using fungicides to prevent diseases. Background technique [0002] Rice bakanae disease, also known as excessive growth disease, occurs in various rice areas in China. It is mainly controlled by using fungicides when soaking seeds. Mimidamide and cyclostrobin are commonly used fungicides in production. For related literature, please refer to " "Modern Pesticides", 2006, 5 (1): 14~19, "Research on Prevention of Rice Bakanae Disease" written by Diao Yamei, etc., can also refer to the publication of a Chinese invention patent application with application number 201510642909.1 "A kind of Rice Seed Soaking Agent of Meconazole and Its Application" (Application Publication No. CN105104423A). [0003] However, these fungicides themselves have a certain toxic effect on seeds, and will affect seed germination and seedling quality to varying degrees, and the...

Problems solved by technology

[0003] However, these fungicides themselves have certain toxic effects on seeds, and will affect seed germination and seedling quality to varying degrees. The degree of influence is related to the variety, seed soaking temperature, and chemical concentration.
