Description

Technical Field

[0001] The invention relates to the technical field of crop fertilizers, in particular to a fertilizer for promoting rooting. Background Art

[0002] The growth and development of plant roots plays an important role in improving the plant's ability to absorb nutrients, increasing biomass and plant quality. In the crop economy, efficient growth of crops is very important. Most existing root-promoting technologies consider applying hormone-containing fertilizers to plants to efficiently stimulate crops to take root quickly in a short period of time. However, the roots that grow are generally thin and weak, and the crops have poor stress resistance and poor quality. Excessive use of hormones can also cause an ecological imbalance in the plants. Therefore, the development of new environmentally friendly fertilizers that promote crop rooting will play a positive role in the development of the crop economy. Summary of the invention

[0003] The object of the present invention is to provide a bacterial fertilizer for promoting the rooting of crops and a preparation method thereof, so as to solve the problem of lack of environmentally friendly rooting-promoting fertilizer in the prior art.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A bacterial fertilizer for promoting rooting of crops comprises, by weight, 20-30 parts of chicken manure, 30-45 parts of fermented crop straw, 10-18 parts of bacterial agent, 5-10 parts of amino acid, 3-7 parts of humic acid, 4-9 parts of potassium dihydrogen phosphite, 15-20 parts of superphosphate, 35-40 parts of urea, 2-5 parts of xylitol, 0.8-1 parts of seaweed extract, 0.1-0.3 parts of borax and 3-7 parts of astaxanthin.

[0006] Furthermore, the bacterial agent includes Trichoderma harzianum, Bacillus megaterium, Bacillus subtilis, rhizobium, and nitrogen-fixing bacteria, and their usage ratios are 7-10: 5-8: 10-15: 1-5: 0.1-3 in parts by weight.

[0007] Furthermore, the amino acid is obtained by filtering and drying peanut meal, monosodium glutamate production tail liquid filtrate, Corynebacterium glutamicum, Pseudomonas aeruginosa, and yeast fermentation liquid.

[0008] Furthermore, the seaweed extract is prepared by the following process: seaweed powder is mixed with a buffer solution and then ultrasonically treated, then alginate, alginase, polymannosuronate lyase and polyguluronate lyase are added for enzymolysis, and the enzymolysis solution is inactivated and filtered.

[0009] Furthermore, the alginate, alginase, polymannuronate lyase and polyguluronate lyase are in a weight ratio of 1:1:1.5:1.

[0010] The invention also provides a method for preparing a bacterial fertilizer for promoting the rooting of crops. Chicken manure and fermented crop straw are crushed and mixed, and then uniformly mixed with other raw materials to obtain the bacterial fertilizer.

[0011] More preferably, the effective live bacteria in the bacterial fertilizer are ≥3.5*10 8 cuf / g.

[0012] Advantages of the present invention include:

[0013] Trichoderma harzianum can secrete a variety of growth-promoting substances to stimulate the growth and development of plant roots. It also has broad-spectrum antibacterial activity, which can inhibit the growth of a variety of pathogens and protect plant roots from diseases.

[0014] Bacillus megaterium can produce a variety of enzymes, such as amylase, protease, etc. These enzymes can decompose organic matter in the soil, provide nutrition for plants, promote the growth and development of plant roots, and improve plant resistance.

[0015] Bacillus subtilis can produce plant hormones and growth regulators to promote root growth; when Bacillus subtilis reproduces in the soil, it can regulate the soil ecological environment, degrade harmful substances in the soil, increase the accumulation and decomposition of organic matter, and promote soil loosening, which is beneficial to the growth and development of plant roots.

[0016] Rhizobia and nitrogen-fixing bacteria can form a symbiotic relationship with plants, providing them with nutrients such as nitrogen while promoting the growth and development of plant roots.

[0017] Xylitol can promote the growth of plant roots, enhance the absorption capacity of plants, and improve the efficiency of plant nutrient absorption. This helps plants better absorb water and minerals from the soil, providing a solid foundation for plant growth. Xylitol is rich in antioxidants, which can enhance plant resistance and reduce the occurrence of diseases and pests.

[0018] Astaxanthin promotes the rapid production of dense and slender root hairs in crops, creating a unique ecological effect that inhibits root-knot nematode disease.

[0019] Seaweed extracts are rich in seaweed polysaccharides, oligosaccharides, phenols, betaine, mannitol and other natural active ingredients that can promote plant rooting. Seaweed extracts contain a variety of plant endogenous hormones, such as cytokinins, auxins, etc., which promote plant rooting. The active ingredients in seaweed extracts can improve soil structure, promote the formation of soil aggregate structure, increase soil biological activity, and are beneficial to the growth and development of the root system. Seaweed extracts can regulate the expression of related genes in plants, promote the absorption and transport of nutrients such as nitrogen by the roots, and provide sufficient nutrients for plant growth. Seaweed extracts contain a variety of functional substances related to stress resistance, such as betaine, mannitol, etc. These substances can enhance the tolerance of plants to adversity and improve the ability of plants to survive under adverse conditions such as drought, pests and diseases.
