Embodiment 1

[0041] Embodiment one: the preparation of the microbial fertilizer of spray drip irrigation compound amino acid chelate

[0042] Add 400ml of water to the reaction kettle, add Ba(OH) 2 400ml, add NaOH 20ml, add donkey bone, donkey skin, cottonseed cake, hoof horns in total 800-1000g, hydrolyze at 100℃-110℃, keep for 6-8h, cool the hydrolyzed solution to 60℃, add a small amount For elemental compounds, heat to 95-110°C and keep for 0.4-1.0h. After the chelate reaction solution is cooled to room temperature, add 0.01% by weight of beneficial microbial flora and mix, and its beneficial microbial flora is composed of four kinds of bacteria: nitrogen-fixing bacteria, phosphorus bacteria, potassium bacteria, and bacillus. The microbial fertilizer product of liquid compound amino acid chelate, see the attached figure 1 .

Embodiment 2

[0043] Embodiment two: the preparation of amino acid trace element chelate

[0044] In order to increase the use effect of this new product, the present invention designs the scheme of adding amino acid trace element chelate. The main components of amino acid trace element chelate are: boron, manganese, zinc, molybdenum and other trace elements.

[0045] In order to make the amount of nutrients added reasonable, that is, effective without being too high, and at the same time to achieve a reasonable ratio of various ingredients without any physical and chemical changes, we have carried out the formulation of the amino acid trace element chelate. optimization.

[0046] The present invention adopts the optimization method of combining single factor test and orthogonal test, and investigates the application effects of different proportions and different content levels of each main component through pot experiments of three crops, selects the best proportion, and finally determine...

Embodiment 3

[0048] Embodiment three: Beneficial microbial strain and its function

[0049] 1. Microbial strain XHS0026N, identified by microbiology as Klebsiella pneumoniae subsp pneumoniae (klebsiella pneumoniae subsp pneumoniaiae) CGMCC.No.1642.

[0050] Strain function: The content of main auxin substances in the XHS0026N culture solution was significantly higher than that of the original strain, and the indole acetic acid substances increased most significantly. In the shake flask test, the content levels in different repetitions ranged from 50-200ppm, and the average content reached more than 66ppm, which was about 15% higher than the starting strain. In addition, the content of gibberellin and cytokinin also increased to varying degrees. The bacterium can also produce a large amount of exopolysaccharides during the fermentation process, and has significant nitrogen-fixing properties.

[0051] 2. The XHS0012K strain in the microbial fertilizer was determined to be Bacillus mucilagi...

Abstract

This invention discloses a method for preparing microbial compound fertilizer chelated with trace elements for spray and drop irrigation. The method comprises: hydrolyzing raw material of protein wastes to obtain composite amino acids, adding trace elements to chelate composite amino acids, and combining with beneficial bacteria (azotobacter, phosphorus fertilizer bacteria, potassium bacteria, bacillus, etc.) to obtain the microbial compound fertilizer. The microbial compound fertilizer has obvious nitrogen fixation, phosphorus and potassium leaching, and growth promotion functions, and has high utility. The release speed is controllable, and the microbial compound fertilizer can improve and activate soil, and improve crop quality.

Description

technical field [0001] The invention relates to a strain and its composition in the field of microbial fertilizers, in particular to a microbial fertilizer for spraying and drip irrigation of compound amino acid chelates and a production method thereof. Background technique [0002] Fertilizer is the "food" and "nutrition" of crops. The emergence of chemical fertilizers and balanced fertilization technology is the product and important symbol of the first agricultural industrial revolution. my country's current chemical fertilizer use per unit area is 1.6 times the average level of the United States and the world, and the total annual use is about 120 million tons. In the past 10 years, the total amount of chemical fertilizers in my country has increased by 90.7%. At present, the application amount of pure nitrogen per hectare has reached 184 hectares, which is 12.3 kilograms per mu. The output has only increased by 9.1%, and the loss rate of nitrogen fertilizer is as high a...
