Embodiment 1

[0033] Embodiment 1 Preparation of Fermented Nucleotide Thalline Broken Extraction Concentrate

[0034] Dilute the yeast slime obtained from the brewery into a 15% turbid liquid, add 4% NaOH to it, break the wall at 80°C for 4 hours, then adjust the pH of the broken liquid to neutral, and remove it with a high-efficiency evaporator 80% moisture, that is to prepare the fermented nucleotide cell wall-broken extraction concentrate of the present invention.

[0035] Among them, the content of nucleotides is 12%, the content of protein is 55%, the content of amino acid is 3.5%, vitamin 1.8%, organic acid 1.4%, and bacterial cell wall 25%.

Embodiment 2

[0036] Example 2 The organic-inorganic compound fertilizer containing γ-polyglutamic acid and nucleotides of the present invention was prepared according to the following steps.

[0037] Mix the preheated phosphate fertilizer, potassium fertilizer and molten urea in a mixing tank to react to form a fertilizer slurry; then mix γ-polyglutamic acid and nucleotide wall-breaking extraction concentrate in proportion and add them to the fertilizer slurry to form The organic-inorganic compound fertilizer slurry containing gamma-polyglutamic acid and nucleotides is granulated by a drum to prepare granular organic-inorganic compound fertilizer particles containing gamma-polyglutamic acid and nucleotides. Among them, the polyglutamic acid content is 1% of the mass of the nitrogen, phosphorus and potassium compound fertilizer, the content of nucleotides is 2% of the mass of the nitrogen, phosphorus and potassium compound fertilizer, and the total organic matter content is 33.8%.

Embodiment 3

[0038] Example 3 According to the following steps, the organic-inorganic compound fertilizer masterbatch containing γ-polyglutamic acid and nucleotides of the present invention is prepared. The organic-inorganic compound fertilizer containing γ-polyglutamic acid and nucleotides prepared in this example is Inorganic compound fertilizer masterbatch can be used as special fertilizer for fruit crops.

[0039] Mix the preheated phosphate fertilizer, potassium fertilizer and molten ammonium nitrate in the mixing tank to react to form fertilizer slurry; the fertilizer slurry is prepared into fertilizer granules through the drum granulation process; The concentrated solution is mixed in proportion, then further concentrated, and added to the surface of fertilizer granules in the fertilizer coating section to form a coating, thereby preparing an organic-inorganic compound fertilizer containing γ-polyglutamic acid and nucleotides. Among them, the polyglutamic acid content is 0.2% of the...

Abstract

The invention discloses an organic-inorganic compound fertilizer master batch containing gamma-polyglutamic acid and nucleotide. The organic-inorganic compound fertilizer master batch contains the following components: polyglutamic acid, nucleotide and nitrogen-phosphorus-potassium compound fertilizer, and is prepared according to a certain ratio, wherein the content of polyglutamic acid is 0.05-2% of the mass of the nitrogen-phosphorus-potassium compound fertilizer, the content of nucleotide is 1-5% of the nitrogen-phosphorus-potassium compound fertilizer, and the total organic content is more than or equal to 15%. By adjusting the ratio between polyglutamic acid and nucleotide, the release cycle of the compound fertilizer can be controlled, and the utilization rate of the fertilizer canbe effectively improved. In addition, besides nucleotide, a fermented nucleotide thallus wall breaking extraction concentrated solution is also rich in nutritional ingredients such as amino acid and vitamin, and these ingredients, as biostimulants, can also improve the growth promoting effect of the fertilizer to crops. The organic-inorganic compound fertilizer master batch containing gamma-polyglutamic acid and nucleotide can remarkably increase the crop yield, and effectively improve soil hardening caused by fertilizer application.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to an organic-inorganic compound fertilizer masterbatch containing gamma-polyglutamic acid and nucleotides, a preparation method and application thereof. Background technique [0002] my country is a big agricultural country and also a big country in the use of chemical fertilizers. The annual consumption of chemical fertilizers is as high as 50 million tons (converted to pure nitrogen, phosphorus and potassium), which has made outstanding contributions to agricultural development and grain production. However, the use of chemical fertilizers has also brought many negative problems, such as low utilization rate of fertilizers, decline in land quality, water pollution, and decline in crop resistance, which largely threaten the sustainable development of agriculture. Organic fertilizers are more and more favored by agricultural practitioners because of their advantages such as h...
