Abstract

The invention relates to a preparation method of a crop drought resistant agent, and belongs to the technical field of crop production. According to the method, firstly, traditional Chinese medicines such as Chinese honeylocust fruits and radix angelicae sinensis are crushed and mixed with diatomite, rice washing water and the like for fermentation; after the filtering, filter slag is dried and carbonized, and is used as a drought resistant agent carrier; filter liquid is mixed with filter liquid of mixed fermentation products of fish bone, pig bone and the like; active ingredients are loaded onto the drought resistant agent carrier; auxiliary agents such as sodium alginate are used for assistance; after the concentration, the crop drought resistant agent is prepared. Active ingredients in various traditional Chinese herbal medicine are sufficiently utilized to be matched with phosphoric ingredients in fermentation products of the fish bone, the pig bone and crab shell; the crop root growth and development are promoted; the polyporous structures of traditional Chinese medicine slag and diatomite carbonization products are utilized; air required by the root breathing effect of crops can be ensured; in addition, residue inorganic matters in the traditional Chinese medicine slag can be slowly released, so that the crops have a developed root system structure; the drought resistance of the crops can be improved, and the crops can still maintain the normal growth and development under the drought condition; the crop yield is improved.

Description

technical field [0001] The invention relates to a preparation method of an anti-drought agent for crops, belonging to the technical field of crop production. Background technique [0002] With the continuous increase of population, the rapid development of industry and the deterioration of ecological environment, we are now facing a more serious problem of water shortage. Drought seriously restricts the increase of crop yield. Therefore, in the face of the increasing population pressure and the increasing scarcity of water resources, drought resistance research has always been an important research content of agriculture. Studies have shown that under drought conditions, osmotic adjustment substances in plants such as soluble sugars, inorganic ions, free amino acids, proline, etc., certain protective enzymes such as superoxide dismutase (SOD), catalase (CAT ), peroxidase (POD), etc., endogenous hormones such as abscisic acid (ABA) and other substances will increase to varyi...
