Preparation method of drought resisting seed soaking agent special for corn

Abstract

The invention provides a preparation method of a drought resisting seed soaking agent special for corn. The preparation method has the advantages that firstly, leach liquor is prepared by 'microwave-assisted secondary crushing plus synergistic extraction of double algae active ingredients by an enzymolysis approach plus double bacteria liquid co-fermentation', the leach liquor is rich in bioactive constituents such as mycose, natural organic matters, nitrogen phosphorus and potassium, and active bacteria, acts on seed surface layers, improves the drought stress resistance of corn seeds, directly supplies nutrition and effective biological active bacteria to the corn seeds, and greatly promotes seed germination; secondly, the special drought resisting seed soaking agent has a film forming characteristic, acts on the corn seed surface layers, forms natural biological activity protective films, and protects the seeds from a seeding phase to a sprouting phase, reduces evaporation of water contained in the corn seeds, promotes accelerated division of embryo cells, and enables radicles and germs to smoothly break through seed coats and germinate, and the protective films can be naturally degraded without residues; thirdly, a use method of the special drought resisting seed soaking agent is seed soaking or spraying, safety, environment friendliness, simpleness and high efficiency are realized, and the operation is facilitated.

Description

technical field [0001] The invention relates to a preparation method of a special drought-resistant seed soaking agent for corn, which belongs to the technical field of biological preparations. Background technique [0002] Corn (Latin scientific name: Zeamays L.) is an annual herbaceous plant of the Poaceae Maize genus, which has a cultivation history of more than 470 years in my country. 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. Maize is widely grown in tropical and temperate regions of the world and is one of the most important food crops in the world. [0003] Corn in my country is mainly distributed in the Northeast, Inner Mongolia, Gansu, Shaanxi, Hebei, Shandong and other northern arid areas. In these areas, annual rainfall is scarce, soil desertification is serious, and water evaporation is large. Hu Ruifa (2004) comprehensively analyz...

Problems solved by technology

The breeding of maize drought-resistant germplasm resources takes a long period, consumes a lot of manpower and material resources, and is prone to unfavorable factors such as trait mutations

Exogenous plant growth regulators mainly include abscisic acid, brassinosteroids, cytokinins, etc., but there are still problems such as high cost, complicated operation, and unstable effect.
