Low temperature resistant lodging-resistant yield-increasing regulator of wheat and preparation method thereof

Abstract

The invention relates to a low temperature resistant lodging-resistant yield-increasing regulator of wheat and a preparation method thereof. The low temperature resistant lodging-resistant yield-increasing regulator of the wheat contains the following components: polyaspartic acid salt with the concentration of 100 g / L, plant growth regulator with the concentration of 20.05-30.05 g / L, active agent with the concentration of 65-67 g / L, speader with the concentration of 65-67 g / L and water used as a solvent. The low temperature resistant lodging-resistant yield-increasing regulator of the wheat can increase the yield of the wheat by more than 20 percent and also enhance the cold resistance and the lodging-resistant capacity of the wheat.

Description

technical field [0001] The invention relates to a plant growth regulator, in particular to a wheat yield-increasing regulator of low temperature resistance and lodging resistance. Background technique [0002] Wheat is the main grain variety in my country and the main ration of the people in the north, and occupies an important position in my country's grain production. At present, my country's wheat sown area is 30 million hectares, with an annual output of 120 million tons, accounting for 26.6% and 24.9% of the total sown area of ​​grain crops and total grain output respectively. Wheat has strong adaptability and a wide planting range. It can be planted from 18° to 50° north latitude. It is widely distributed in 30 provinces, municipalities and autonomous regions in my country, and the dominant production areas are mainly concentrated in Hebei, Henan, Shandong, Jiangsu, Anhui, and Shaanxi. and Sichuan Province, the sown area accounts for 65.12% of the country's wheat sown ...

AI Technical Summary

Problems solved by technology

Among them, the cultivation technical measures include: before sowing, combined with deep plowing, apply more organic fertilizers to increase temperature and moisture retention, ensure the transformation and upgrading of winter wheat seedlings, and promote the formation of strong stalks and large ears of winter wheat; For winter wheat, proper watering before cooling can play a role in storing moisture and preventing cold, cultivating strong seedlings, slowing down the drop in ground temperature, and promoting the growth of wheat seedlings; the above measures can reduce freezing damage and chilling damage to a certain extent, but the measures require a large amount of work and need to be implemented It takes a certain period of time, and when a cold wave occurs, it is often impossible to implement it quickly and it is impossible to prevent it

Active cold resistance measures include topdressing urea combined with watering, spraying potassium dihydrogen phosphate on leaves, and plant growth retardants such as paclobutrazol and chlormequat. Although these measures have increased the cold resistance of wheat to a certain extent, the leaves The effect of surface spraying retarder treatment on wheat yield reduction is even greater than the impact of chilling injury, so the actual application effect is not good
