Description

Technical Field

[0001] The invention belongs to the technical field of agricultural fertilizers, and particularly relates to a special organic fertilizer for kiwi fruit and a preparation method thereof. Background Art

[0002] Kiwifruit is a fruit with high nutritional value and significant economic benefits. Its growth requires high soil fertility and nutrient supply. While traditional chemical fertilizers can quickly provide nutrients, long-term use can lead to soil compaction, decreased fertility, and environmental pollution. Organic fertilizers, with their rich organic matter and diverse nutrients, can improve soil structure, increase soil fertility, and promote the healthy growth of kiwifruit. However, there is currently a lack of organic fertilizer products specifically tailored to the growth needs of kiwifruit. Furthermore, the complex and costly preparation processes of existing organic fertilizers limit their widespread application. Summary of the Invention

[0003] In view of the above problems, the present invention aims to provide a special organic fertilizer for kiwi fruit, which can meet the nutritional needs of kiwi fruit growth, improve the soil environment, and increase the quality and yield of the fruit.

[0004] In order to achieve the above object, the technical solution adopted in the present invention is: A special organic fertilizer for kiwi fruit comprises the following components by weight: 50-70 parts of livestock and poultry excrement, 30-50 parts of kiwi fruit branch and leaf residue, 10-20 parts of soybean meal, 5-10 parts of bone meal, 3-8 parts of humic acid, and 1-3 parts of microbial agent.

[0005] Furthermore, the microbial agent includes Bacillus subtilis, which is deposited in China Center for Type Culture Collection with a deposit number of CCTCC NO: M 2022399, Bacillus subtilis, yeast and lactic acid bacteria, with a ratio of 1:1:1:1.

[0006] The present invention also provides a method for preparing a special organic fertilizer for kiwi fruit, comprising the following steps: (1) Raw material pretreatment: livestock and poultry manure, kiwi fruit branch and leaf residue, soybean meal and bone meal are crushed separately to make the particle size less than 5mm; (2) Mixed fermentation: Mix the treated raw materials with humic acid, add microbial agents, adjust the moisture content to 50%-60%, and pile for fermentation; (3) Fermentation process control: During the fermentation process, the compost is turned regularly to maintain the temperature at 50-65°C. The fermentation cycle is 20-30 days. (4) Post-processing: After fermentation is completed, the compost is dried, crushed, and passed through an 80-mesh sieve to obtain organic fertilizer specifically for kiwifruit.

[0007] During the fermentation process, the frequency of regular turning of the pile is once every 3-5 days.

[0008] Compared with the prior art, the present invention has the following beneficial effects: (1) Comprehensive nutrition: The organic fertilizer of the present invention is rich in macroelements such as nitrogen, phosphorus, potassium, and trace elements such as calcium, magnesium, and iron, and can meet the nutritional needs of kiwifruit at different growth stages.

[0009] (2) Improve soil: Rich in organic matter, it can effectively improve soil structure, increase soil aeration and water retention, and reduce soil compaction.

[0010] (3) Improve fruit quality: Using the organic fertilizer of the present invention can increase the sugar content of kiwi fruit by 10%-20%, increase the vitamin C content by 15%-25%, and reduce the occurrence of diseases and pests.

[0011] (4) Environmental protection and sustainability: Using agricultural waste and livestock and poultry manure as the main raw materials, we can achieve the recycling of resources and reduce environmental pollution. DETAILED DESCRIPTION

[0012] The technical solution of the present invention is described in detail below with reference to specific embodiments.

[0013] A special organic fertilizer for kiwi fruit comprises the following components by weight: 50-70 parts of livestock and poultry excrement, 30-50 parts of kiwi fruit branch and leaf residue, 10-20 parts of soybean meal, 5-10 parts of bone meal, 3-8 parts of humic acid, and 1-3 parts of microbial agent.

[0014] The microbial agent includes Bacillus subtilis XG-1 (deposited with the China Center for Type Culture Collection, Wuhan University, on April 8, 2022, with the deposit number CCTCC NO: M2022399), Bacillus subtilis, yeast, and lactic acid bacteria, in a ratio of 1:1:1:1. The preserved Bacillus subtilis has a characteristic of producing proteases and hemicellulases, which are important for lignin degradation.

[0015] The present invention also provides a method for preparing a special organic fertilizer for kiwi fruit, comprising the following steps: (1) Raw material pretreatment: livestock and poultry manure, kiwi fruit branch and leaf residue, soybean meal and bone meal are crushed separately to make the particle size less than 5mm; (2) Mixed fermentation: Mix the treated raw materials with humic acid, add microbial agents, adjust the moisture content to 50%-60%, and pile for fermentation; (3) Fermentation process control: During the fermentation process, the compost is turned regularly to maintain the temperature at 50-65°C.
