Problems solved by technology

However, repression, hoeing or nibbling will cause mechanical damage to the plant, enhanced respiration, increased nutrient consumption, increased water evaporation, and reduced sugar content in tiller nodes, thus weakening the frost resistance and being vulnerable to freezing damage, affecting the growth and production of wheat.

Abstract

The invention relates to a chemical control preparation for enhancing the stress resistance and the seed yield of wheats and application thereof, in particular to a chemical regulation preparation for enhancing the low temperature resistance, the lodging resistance, the drought resistance and the seed yield of the wheats and application thereof, belonging to the technical field of crop growth and regulation. The chemical control preparation for enhancing the stress resistance and the seed yield of the wheats comprises the following compositions per kilogram: 0.02-0.06g of auxin, 0.8-1.2g of fluroxypyr, 1ml of surfactant, 1ml of non-protonation polar solvent and the balance of water. The chemical control preparation provided by the invention can control vigorous growth before winter and invalid tillering amount of crops above the ground part, save the nutrients, promote root downward growth, enable stem bases of most wheats to be vertical or approximately vertical to the ground and enhance the winter and prevernal freezing damage resistance and cold damage resistance of plants when enhancing the drought resistance of the plants.

Description

technical field [0001] The present invention relates to a chemical control agent for improving stress resistance and grain yield of wheat and its application, especially a chemical control agent for improving wheat resistance to low temperature, lodging and drought, and grain yield and its application, which belongs to crop growth control technology field. technical background [0002] The tillering status of wheat directly affects the quality of the population structure and the yield. Sowing date is a key factor affecting wheat tillering. Early sowing will lead to faster growth of wheat, increased number of tillers per plant, and excessive population size, which will easily lead to vigorous growth of wheat seedlings, thin stems, and reduced nutrient storage at tiller joints, especially sugar content, which is not conducive to safe wintering of wheat; late sowing of wheat, Due to the short growth period before winter, the root system is small, the root is shallow, and the ...
