Embodiment 1

[0035] Embodiment 1: the preparation of fulvic acid chelated zinc biological fertilizer

[0036] The invention specifically provides a preparation method of fulvic acid chelated zinc biological fertilizer, and the specific preparation method steps are as follows:

[0037] (1) Preparation of fulvic acid chelated zinc solution: according to the ratio of parts by weight, 1-2 parts of biochemical fulvic acid, 4-6 parts of zinc sulfate, 9-11 parts of potassium dihydrogen phosphate, 45-55 parts of water Mix evenly, put it into the primary reaction kettle, adjust the pH to 6.0-7.0, the reaction temperature is 30-40 ° C, the reaction time is 40-60 min, after the primary reaction is completed, it is transferred to the secondary reaction kettle, and the reaction temperature is 50 -70 ℃, the reaction time is 20-30min, after the secondary reaction is completed, it is transferred to the tertiary reactor, the reaction temperature is 75-85 ℃, and the reaction time is 15-25min, after the chel...

Embodiment 2

[0043] Embodiment 2: the preparation of biochemical fulvic acid

[0044] Biochemical fulvic acid, the specific preparation method steps are as follows:

[0045] (1) Processing of raw materials: 11-13 parts of straw, 4-6 parts of bran, 2-4 parts of sawdust, 2-4 parts of walnut green husk, 1-2 parts of thin-skinned walnut shell, 1-2 parts of urea -2 parts, mix evenly, crush mechanically, then add 30-40 parts of clean water to mix to obtain mixed raw materials;

[0046] (2) First-stage fermentation: by weight percentage, to the mixed raw material obtained in step (1), add 5% of the first-stage fermentation mixed inoculum, when the temperature of the material rises to above 65°C, maintain for 48h, and turn over during the period. Mix twice to obtain the first-stage fermentation product;

[0047] (3) Second-stage fermentation: by weight percentage, to the first-stage fermentation obtained in step (2), add 20% of the mixed raw materials prepared in step (1), and 5% of the second-s...

Embodiment 3

[0053] Example 3: Optimization experiment of biochemical fulvic acid preparation conditions

[0054] (1) Optimization of biochemical fulvic acid raw materials

[0055] Straw, bran, sawdust, walnut green skin, thin-skinned walnut shell, and urea were mixed according to different proportions, mechanically crushed, and then 35 kg of water was added, and 3% of the first-stage fermentation mixed bacterial agent was added to the mixed raw materials. When the temperature rises to above 65°C, keep it for 48h, and stir twice during the period. After the first stage of fermentation, add 20% of the mixed raw materials and 3% of the second-stage fermentation mixed inoculum to the feed liquid, mix evenly and ferment for 96h, and stir during the period. 4 times to obtain the second-stage fermentation product; the ratio of the first-stage fermentation mixed bacterial agent is: acidophilus chain: Bacillus pumilus: white rot fungus: Clostridium thermocellum = 1:1:1:1, and the second-stage ferm...

Abstract

The invention discloses a fulvic acid chelated zinc biological fertilizer and its application in walnut planting. The present invention prepares the fulvic acid chelated zinc biological fertilizer by using the mixed bacterial agent and the fulvic acid chelated zinc solution to fuse the fulvic acid chelated zinc fertilizer. After the humic acid chelated zinc fertilizer is applied on the walnut leaf surface, the microorganisms rapidly multiply and can degrade the pesticide and chemical fertilizer residues. Eliminate heavy metal pollution, fulvic acid chelated zinc biological fertilizer utilizes the strong complexing ability of fulvic acid and zinc ion chelation, which is more conducive to the absorption of walnut leaves, improves the utilization rate of zinc fertilizer, improves the quality of walnut products, and reduces pesticides The zinc content in walnut kernels is relatively high, so that the purpose of enriching zinc in walnuts to improve the health care effect is achieved.

Description

technical field [0001] The invention relates to the field of chemical fertilizers, in particular to the technical field of fulvic acid chelated zinc biological fertilizer and its application in walnut planting. Background technique [0002] Walnut (Juglans regia L.) is an important woody oilseed species with high economic, ecological and social benefits. In recent years, with the country's vigorous support for the woody oilseed industry, the market demand has gradually increased, and the cultivation area of ​​walnut has continued to expand. Water and fertilizer management is a key factor to achieve high walnut yield. Scientific fertilization is a relatively simple and effective way to increase walnut yield. The content of nutrient elements in leaves can reflect the demand and utilization of various nutrients in the tree. Dynamic analysis can be used as a basis for fertilization. The leaves not only provide the mineral nutrients needed for fruit growth and development, but a...
