Problems solved by technology

[0003] Plant growth stimulating hormone has the functions of promoting the growth of roots, stems and leaves of crops, improving the stress resistance of crops, stimulating plant cell division, promoting the formation of chlorophyll, enhancing plant photosynthesis, promoting growth, early maturity, preserving flowers and fruits, increasing Yield, improve crop quality to achieve increased crop yield, high yield, regulate crop growth, enhance crop disease resistance, improve crop quality and yield, so as to achieve weight loss and drug reduction, and do not pollute the environment. Therefore, plant growth stimulants are used in agriculture. It is of great significance, but the development of plant growth stimulant technology in agriculture in China is relatively slow. First, due to weak scientific research, there is a lack of breakthroughs in fermentation technology, preparation methods and applications.
Second, application and scientific research are even more disconnected, and the lack of accurate application data makes the development of promotion and application work lag behind

Abstract

The invention relates to the field of biostimulants and particularly relates to a preparation method for a plant growth stimulant and an application of the plant growth stimulant. The plant growth stimulant is prepared through preparing a seed solution from yellow-ocher streptomyces, inoculating the seed solution to a fermentation tank containing a mixed culture medium of maize meal, soybean meal, glutamic acid, potassium dihydrogen phosphate, sodium chloride, seaweed powder and cerealose which are in a certain ratio, carrying out fermentation, and uniformly mixing fermentation broth of the yellow-ocher streptomyces with multivitamins, multiple amino acids and algal polysaccharides which are in a certain ratio. The plant growth stimulant disclosed by the invention can be added into organic fertilizers, water-soluble fertilizers and microbicides according to a certain ratio so as to carry out synergizing, increase yield, prolong drug effect duration and enhance immunity. The plant growth stimulant disclosed by the invention has the effect of playing a role in stimulating natural courses of plants, including being beneficial to the enhancement of nutrient absorption, nutritional effects, abiotic stress resistance and crop quality, promoting the growth of roots, stems and leaves of crops, and improving the resistance of the crops, can be used for stimulating cell division of plants, promoting formation of chlorophyll and enhancing photosynthesis of the plants and has the aims of promoting growth, advancing ripeness, keeping enough flowers and young fruits, increasing yield, improving crop quality and achieving the yield increase and high yield of the crops.

Description

technical field [0001] The invention belongs to the technical field of agricultural growth stimulants, and more specifically relates to a preparation method and application of plant growth stimulants. Background technique [0002] my country's traditional agricultural ecosystem has been greatly damaged in the past hundred years; the use of chemical fertilizers and chemical pesticides has become more and more widespread, and the amount of use has increased, which has aggravated environmental pollution, soil ecological damage, and soil acidification and soil salinity. Waterlogging, soil compaction, soil fertility decline, more and more refractory chemical substances accumulate, and bottlenecks in crop growth, resulting in reduced crop production and quality decline, and soil-borne diseases, plant deficiencies, and plant diseases are becoming more and more serious. The application of physical, chemical, and treatment methods has little effect. If this continues, the prospect is w...
