Problems solved by technology

[0003] The existing adjustment of transplanting period and cultivation methods can solve the problem of regional low-light adversity. However, under the background of climate change, extreme climates occur frequently, and low-light adversity occurs at different times and in different places. Conventional technology Measures cannot effectively solve the problem

Abstract

The invention relates to a compound regulator for plant growth and a use method thereof in rice shade-enduring planting and belongs to the technical field of plant growth regulation. The compound regulator comprises the following raw materials in parts by weight: 0.25-0.30 part of a triazole plant growth regulator, 0.0090-0.01 part of gibberellin and 0.5-3 parts of an acidic phosphate and potash fertilizer. The use method of the compound regulator for plant growth in rice shade-enduring planting comprises the step of mixing the compound regulator for plant growth with 800-1200 parts of water.According to the invention, the combination of gibberellin, the triazole plant growth regulator and the acidic phosphate and potash fertilizer is capable of effectively relieving weak light stress ofrice plants and boosting normal growth of rice.

Description

technical field [0001] The invention belongs to the technical field of plant growth regulation, and in particular relates to a compound plant growth regulator and a method for using the same in shade-tolerant planting of rice. Background technique [0002] Rice is a light-loving crop. Less regional light and continuous rainy weather will lead to reduced light for rice and reduce rice yield. Therefore, it is necessary to adopt certain technical means to promote rice growth when rice suffers from low-light adversity, and alleviate the impact of low-light adversity on rice growth and development. influences. The existing technology mainly solves the problem of low light adversity through cultivation methods, such as adjusting the transplanting time of rice, avoiding rainy and low light weather, combining the plant type characteristics of rice varieties, determining a reasonable planting density, and performing timely water and fertilizer regulation on the population, thereby R...
