Abstract

The invention provides a seed-dressing agent capable of improving lodging-resistant property of maize. The seed-dressing agent is prepared from the following components in parts by mass: 15-20 parts of elecampane, 3-5 parts of mother chrysanthemum, 10-15 parts of rhizoma cyperi, 8-10 parts of radix paeoniae alba, 3-5 parts of folium cortex eucommiae, 1-3 parts of astragalus membranaceus, 3-5 parts of crowndaisy chrysanthemum, 8-10 parts of arundina graminifolia, 3-5 parts of poria cocos and 5-8 parts of root barks of white mulberries. The invention also provides a preparation method thereof. In a same growing environment, compared with a common marketed seed-dressing agent, after heavy rain and strong wind in the later growing period of maize, the lodging-resistant rate of a control group of maize exceeds 30%, and the lodging-resistant rate of a base fertilizer group provided by the invention is lower than 6%.

Description

technical field [0001] The invention relates to a seed dressing agent for improving lodging resistance of corn. Background technique [0002] The history of corn cultivation in my country is about 470 years. At present, my country's sown area is about 300 million mu, second only to rice and wheat, ranking third among food crops, and second only to the United States in the world. It is widely planted in tropical and temperate regions of the world and is an important cereal. During the growth of corn, in case of strong wind and heavy rain, lodging in large areas is prone to occur, which will seriously reduce the yield of corn. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides a seed dressing agent for improving the lodging resistance of corn. After use, the lodging resistance is greatly improved. [0004] The invention provides a seed dressing agent for improving the lodging resistance of corn. The seed dressing age...
