Embodiment 1

[0020] An organic fertilizer for preventing and treating walnut yellow leaf disease, empty shells and white tips, which consists of: 410kg of soybean meal, 150kg of ferrous sulfate, 30kg of zinc sulfate, 10kg of borax, 30kg of potassium sulfate, 70kg of citric acid, 0.5kg of enzyme bacteria, spores Bacillus 0.5kg, water 299kg.

[0021] Its preparation method is as follows:

[0022] (1) Fermentation of soybean meal

[0023] Mix the soybean meal with water, add the mixed bacteria of Bacillus and enzyme bacteria, mix well, aerobically ferment at 25-35°C for 5-7 days, and ferment at lower than 20°C for 7-10 days. During the fermentation process, turn the materials for 4 -6 times to obtain soybean meal fermentation product A;

[0024] (2) Mix citric acid with sulfate, and mix citric acid with ferrous sulfate, zinc sulfate, borax, and potassium sulfate to obtain a mixture B of citric acid and sulfate;

[0025] (3) Mix half of the mass of the soybean meal fermentation product A ob...

Embodiment 2

[0030] An organic fertilizer rich in active iron and zinc, which consists of 410kg of soybean meal, 150kg of ferrous sulfate, 30kg of zinc sulfate, 10kg of borax, 30kg of potassium sulfate, 70kg of citric acid, 1.0kg of enzyme bacteria, and 299kg of water.

[0031] Its preparation method is as follows:

[0032] (1) Fermentation of soybean meal

[0033] Mix soybean meal, water, and enzyme bacteria, aerobically ferment for 5-7 days at 25-35°C, and ferment for 7-10 days at below 20°C. During the fermentation process, turn the materials 4-6 times to obtain soybean meal fermentation products A;

[0034] (2) Mix citric acid, ferrous sulfate, zinc sulfate, borax, and potassium sulfate to obtain a mixture B of citric acid and sulfate;

[0035] (3) Mix half of the mass of the soybean meal fermentation product A obtained in step (1) with the mixture B obtained in step (2), and use the sticky substance produced during the soybean meal fermentation process to bind the above-mentioned mi...

Abstract

The invention discloses an organic fertilizer formula rich in active iron and zinc. According to the fertilizer, through the steps that iron and zinc ions are chelated by citric acid and secondarily chelated by amino acid and polypeptide materials which are generated after bean pulp peridia and bean pulp are fermented, the effectiveness of iron and zinc is improved to the maximum limit, and the problems that the effectiveness is low if ferrous sulfate is directly applied, and EDTA-Fe is expensive and difficult to apply and popularize in large area are solved; the bean pulp materials are rich in nutrient elements such as nitrogen, phosphorus, calcium and sulfur, the nutrient elements such as zinc, boron and potassium are appropriately supplemented in the fertilizer, and therefore the problems of the physiological iron deficiency Panama disease of the walnuts, the vacant shell disease of the walnuts, the white tip disease of the walnuts, physiological fruit drop and the like are effectively solved.

Description

technical field [0001] The invention relates to an organic fertilizer, in particular to an organic fertilizer rich in active iron, zinc and boron for preventing and treating iron-deficiency "yellow leaf disease" of walnuts on calcareous soil, and "white tip" of empty shells and hemp walnuts, and a preparation method thereof . Background technique [0002] The high pH value of calcareous soil in northern China leads to low soil nutrients such as iron and zinc. Walnut is one of the main fruit trees in this area. Iron deficiency "yellow leaf disease", empty shell, hemp walnut "white tip" and so on are the main factors leading to the reduction of walnut yield and quality. At present, excessive application of nitrogen, Phosphorus and potassium fertilizers have aggravated the above-mentioned physiological diseases of walnuts to a certain extent, and solving the iron-deficiency "yellow leaf disease" of fruit trees has always been a difficult problem in the world. The main reason i...
