Problems solved by technology

[0003] CN104336020A discloses a plant growth regulator compound, which contains plant growth regulators such as uniconazole and diethyl hexanoate, the plant growth regulator compound can move the center of gravity of crops down, improve the lodging resistance of crops, The effect of increasing crop yield and improving product quality is obvious, but the effect of reducing empty stalk rate and promoting early maturity is not satisfactory
Ning Tangyuan et al. (the impact of Lifengshou on the growth characteristics and yield of spring maize, Maize Science, the 3rd phase, the 67th-68th page, on September 25th, 2002) disclosed the effect of sodium ligninate (SL) on maize. Application (treatment method is soaking seeds), has the effects of increasing plant height, improving ventilation and light transmission, increasing the area of ​​three-leaf leaves on the stick, increasing stem diameter and yield, but has no obvious effect on reducing the empty stalk rate of corn and promoting early maturity.

Abstract

The invention discloses a corn compound spraying agent, a preparation method, a using method and application thereof, and belongs to the field of plant growth regulators. The corn compound spraying agent mainly comprises sodium lignite and m-PB-Fu. The invention further discovers that after sodium lignite and m-PB-Fu are subjected to two-element compound and then are mixed with corn seedling leaching liquid, the three components cooperate to achieve a quite obvious cooperative synergism effect, and the effects in the aspects of decreasing bare plant rate of corn, promoting precocity, improving lodging resistance force, increasing yield, and the like are remarkably improved. The invention furthers discloses the preparation method, the using method and application of the corn compound spraying agent.

Description

technical field [0001] The present invention relates to a spraying agent for crops, in particular to a composite spraying agent which is suitable for corn and uses a variety of plant growth regulators and corn seedling extracts as active ingredients. The present invention further relates to the compound spraying agent The application of the agent in reducing the empty stalk rate of corn, promoting early maturity, improving lodging resistance and yield, etc. belongs to the field of plant growth regulators. Background technique [0002] Corn is one of the main food crops in China, the main source of livestock feed, and also an important industrial raw material. With the continuous increase of planting density, the problems of corn lodging, empty stalks and overgreen and late maturity are becoming more and more serious. In order to solve the above problems, there are mainly solutions such as breeding, cultivation and plant growth regulators. Breeding requires a long period of...
