Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] The method for enhancing the resistance to rice bakanae disease fungicides comprises the steps in turn:

[0035] ① Preliminary seed selection, cleaning rice seeds, preliminary removal of impurities and empty grains;

[0036] ② Germination test, germination test is carried out in the incubator to ensure that the seeds used have normal germination ability;

[0037] ③ Sunny days to dry seeds, choose sunny days with the highest temperature not higher than 25°C for 1 to 2 days;

[0038] ④Salt water seed selection, using salt water to remove seeds with poor grouting and filling;

[0039] ⑤ Wash the seeds, wash the seeds with clean water, and remove the salt outside the chaff;

[0040] ⑥Initiate with clean water, soak the selected seeds with clean water, the amount of water is subject to completely submerging the seeds; soaking time is 8 to...

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...
