Rice and wheat grain filling accelerant and preparation method thereof

Abstract

The invention provides a rice and wheat grain filling accelerant and a preparation method thereof. The grain filing accelerant consists of monopotassium phosphate, spermidine, sec-alkyl sodium sulfate and water, wherein phosphorus and potassium nutrient elements, a plant growth accelerating substance named spermidine and the plant organ surface activating agent named sec-alkyl sodium sulfate have the supplementary effect, and are prepared into a solution, and the solution is sprayed after rice and wheat are blossomed for 5-10 days, so that the effect of absorbing phosphorus and potassium elements and spermidine by plants can be accelerated, the grain grouting of rice and wheat is enhanced obviously, and the grain filling degree, the grain gravity and the yield are enhanced. The phosphorus and potassium nutrient elements, the plant growth accelerating substance and the plant organ surface activating agent are blended integrally, so that the problem that the substance applying effect promoted by the traditional leaf fertilizer or grain filling is poor is solved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a rice and wheat grain filling accelerator and a preparation method thereof. Background technique [0002] The grain filling period of cereal crops such as rice and wheat is a critical period for the formation of grain weight. The quality of grain filling is directly related to the level of grain weight and yield, especially for the breeding and application of high-yielding rice and wheat varieties with large spikes. Poor filling and low kernel weight have become a prominent problem (Yang and Zhang, 2010; Zhu et al., 2011; Zhang et al., 2012). For a long time, people have sprayed phosphorus and potassium foliar fertilizers or applied plant regulating substances such as rice-wheat grain-increasing and weight-increasing agents, grain-filling, grain-filling, etc., as an important measure to promote grain filling of rice and wheat (Li Jianmin et al., 1999; Liu Xiuli et al., 20...
