Crop production-increasing resistance-inducing nutritional agent, preparation method and use method thereof

Abstract

The present invention discloses a novel crop production-increasing resistance-inducing nutritional agent, a preparation method and a use method thereof. The novel crop production-increasing resistance-inducing nutritional agent comprises GA3, ABA, boron and a dispensing agent. The preparation method comprises: uniformly mixing and stirring GA3, ABA and boron, and adding a dispensing agent at a room temperature to obtain the finished product. The nutritional agent has characteristics of good water solubility, easy absorption by crops, easy use, low use amount, stable performance and long shelf life, and can provide trace nutrient element boron required by flowering stages of crops such as rice, corn, wheat, sorghum and the like. In addition, with the novel crop production-increasing resistance-inducing nutritional agent, hormonal balances in crop bodies can be regulated, stress resistance of crops can be improved, photosynthesis products can be promoted to quickly transfer to floral organs, yield can be effectively increased, quality can be improved, and good economic benefits can be provided.

Description

technical field [0001] The invention belongs to the field of agricultural foliar fertilizer and its preparation, and in particular relates to a novel crop production-increasing inducer and resistance nutrient and its preparation and use method. Background technique [0002] At present, rice, corn, wheat, sorghum and other crops (especially hybrid rice) in agricultural production often encounter abnormal weather (high temperature and high humidity, low temperature and rain, little sunshine) during the heading and flowering period, resulting in difficulty in heading, abnormal flower organs, The rate of grain filling is slow, and the amount of dry matter accumulated by photosynthesis is far from meeting the needs of grain filling, resulting in imbalances of various hormones inside the plant, difficulty in heading, less pollen, abnormal pollen granules, low seed setting rate after maturity, and a decrease in thousand-grain weight. . In order to solve this practical production p...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the crop foliar spray nutrition caused by incomplete functional components, single effect and short duration of the nutrient used in current production to promote earing and seed strengthening or the regulator of foliage spraying. In view of the disadvantages such as inconspicuous efficacy, difficulty in being absorbed by leaves, and poor persistence in the use of pesticides or regulators, a crop production-inducing inducer and resistance nutrient and its preparation and use methods are provided.
