Description
Technical Field
The invention belongs to the technical field of biological fertilizers, and particularly relates to a biological fertilizer composition containing brassinolide and 5-aminolevulinic acid.
Background
The current biological fertilizer comprises a biological organic fertilizer, a compound microbial fertilizer and the like, and mainly takes the biological organic fertilizer as a main component, but the biological organic fertilizer is not friendly to environment and an applicator due to straw decomposition agents, livestock and poultry manure, organic garbage leavening agents and the like, has poor persistence, has limited effects of increasing the yield of crops and improving the quality, and has unstable target efficiency of microbial strains in the compound microbial fertilizer, unreasonable formula and poor stress resistance.
Brassinolide is a novel green environment-friendly plant growth regulator. In 1970, Grove, a scientist in the United states, isolated it from canola pollen and, through studies on its crystalline structure, found that it is a sterol compound, which is called brassinolide. This is one of the latest plant growth regulators in the world, called phytohormones of the sixth class. The biological activity of the hormone is far more than that of the existing five major hormones. The brassinolide has great effect in promoting crop production, is suitable for any period of growth cycle of various plants, and can act on various physiological periods of plants according to the requirements of the plants in various periods. Brassinolide is suitable for use in a variety of plants, such as: commercial crops, rice, wheat, vegetables, fruits and the like. Has effects of promoting growth, fertilization and fruit enlargement. In addition, it also has the functions of increasing yield, coordinating nutrition balance and strongly rooting. Can improve the stress resistance of plants such as drought resistance, cold resistance, salt and alkali resistance and the like. The fertilizer has the function of death and revival for crops which are suffered from insect pests, phytotoxicity or alkali salt damage.
5-aminolevulinic acid (A L A) widely exists in animal, plant and microbial cells, and is a precursor for biosynthesis of tetrapyrrole compounds such as chlorophyll, heme, porphyrin and vitamin B12A L A can be used as plantThe low concentration A L A is beneficial to chlorophyll synthesis, improves the stability of chlorophyll and photosystem II, promotes photosynthesis A L A also plays a very important role in the antioxidant metabolism of plants, and the low concentration A L A accelerates reactive oxygen species ROS (e.g., H)2O2) The generation of the alpha-glucosidase further promotes the activity of some key antioxidase (such as glutathione reductase, ascorbic acid peroxidase, dehydroascorbic acid reductase, superoxide dismutase, catalase, peroxidase and the like), and the low concentration A L A has the effect of promoting crops to respond to various adverse growth conditions (such as saline-alkali, low temperature, weak illumination, drought and the like), so the alpha-glucosidase is also an application research hotspot of A L A.
Brassinolide is mainly a single aqueous solution with different concentrations in the current market. The product of 5-aminolevulinic acid is mainly a fertilizer of dry trace elements. The main problem is that brassinolide has a short time to exert its action and photosynthesis is not effectively improved in promoting growth. The single 5-aminolevulinic acid product is primarily responsible for enhanced photosynthesis, but has no advantage in cell differentiation and division.
