Problems solved by technology

However, the above-mentioned method cannot eliminate the influence of seed dormancy and seed coat difference due to its direct soaking of dried seeds, and only using the germination rate as an evaluation index cannot truly evaluate the moisture resistance.

Abstract

The invention discloses a moisture resistance regulating agent of rape. The moisture resistance regulating agent of rape disclosed by the invention comprises salicylic acid, 6-benzyl adenine, N-(2-benzimidazolyl)-methyl carbamate and boric acid, wherein the concentration of salicylic acid is 20-50 mg / L; the concentration of 6-benzyl adenine is 1 microgram / L; the weight percentage of N-(2-benzimidazolyl)-methyl carbamate is 0.01-0.05%; and the weight percentage of boric acid is 0.1-0.2%. By spraying the moisture resistance regulating agent of the rape disclosed by the invention on the part of the rape damaged by the waterlogging on the ground at 3-5 leaf development stage, the moisture resistance of the rape can be significantly improved, the downy mildew morbidity of the rape seedlings can be reduced and the yield of the rape can be increased by 7-10%. The rape moisture resistance regulating agent is convenient to use and low in cost, and has no toxic or side effects.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a rapeseed moisture-resistance regulating agent, and also relates to the application of the rapeseed moisture-resistance regulating agent. Background technique [0002] Rapeseed is an important oil crop in my country. Its output and sown area both rank first in the world. It is an important source of edible oil and protein feed, as well as an important industrial raw material. The Yangtze River Basin is the main planting area of ​​rapeseed in China, but the production of rapeseed in this area has the following major characteristics: First, rice and rapeseed are mostly used in rotation, and the water in the field is not easy to drain after rice harvesting, which will cause moisture damage to the growth of rapeseed; second, it is wet and rainy in winter Rapeseed seedlings are prone to wet damage and waterlogging, which seriously affect the yield of rapeseed. The main performa...
