Method for destroying wheat seed dormancy

Abstract

The invention relates to a method for destroying wheat seed dormancy. The method comprises steps of seed selection, wheat seeds immersion by clear water with different temperatures, seeds immersion by a sodium hydroxide solution and neutralization by sulfuric acid, seeds immersion with composite immersion liquid, and germination accelerating. The method can rapidly destroy the wheat seed dormancy, greatly shortens the germination time of wheat seeds, promotes obvious increase of the germination rate, and guarantees the timely sowing production by planters. The method has the characteristics of simple requirement condition, convenient operation, easy grasping, low cost, environmental protection, and no environmental pollution, the germination rate of the wheat seed reaches as high as 99.2%, the germination time of the wheat seed is shortened by 40% by comparing with the germination time of common wheat, and the problem that seedling emergence is untidy and secondary dormancy can be generated due to drying after processing in a common seed dormancy destroying method can be solved.

Description

technical field [0001] The invention relates to the field of planting, in particular to a method for breaking dormancy of wheat seeds. Background technique [0002] Vigorous seeds that cannot germinate are called dormant seeds. If the dormant seeds are sown into the ground, the emergence rate will be low, resulting in reduced yield; wheat seeds generally have a dormant period, and wheat The dormancy period is longer and varies among varieties. my country is a large agricultural country, and wheat is the staple food. Quite a few farmers now only know to choose good varieties and apply chemical fertilizers, but they are not clear about the concept of dormancy period. For agricultural production, the germination power of dormant seeds will be reduced, which will seriously affect Field emergence rate. However, some existing methods for breaking dormancy of wheat seeds have general effects, and the problem of only breaking part of the dormancy of seeds often occurs. Contents o...
