Special-purpose fruit tree biological organic fertilizer and preparation method thereof

Abstract

The invention relates to a special-purpose fruit tree biological organic fertilizer and a preparation method thereof. The special-purpose fruit tree biological organic fertilizer is characterized by using 50%-65% (in percentage by weight) of fermented and cured organic matter as the material, wherein the organic matter is mixed with 10%-20% of powdered carbon, 5%-20% of shell powder, 1%-5% of seaweed meal, 1%-5% of chitin and 0.1%-0.2% of ocean brevibacillus laterosporus, bacillus subtilis and sphingomonas mixture powder (the weight ratio of the three bacteria being 1:1:1, and the number of effective microorganisms in each kilogram of the materials is 1012 or more). The special-purpose fruit tree biological organic fertilizer disclosed by the invention can be used for continuously supplying nutrients required by growth and development of the plant at each stage from the aspects including water retention, nutrition slow release and the like, can be used for improving the soil physical and chemical properties and promoting formation of soil aggregates. Most of materials used by the special-purpose fruit tree biological organic fertilizer are aquaculture by-products, so that the waste is changed into valuable, the environment-friendly effect is obvious and perpetual harms are not caused to the soil.

Description

technical field [0001] The invention relates to a bio-organic fertilizer for regulating the balanced growth and development of fruit trees and improving the internal and external quality of fruits and a preparation method thereof, belonging to the technical field of special compound fertilizers for fruit trees. Background technique [0002] At present, Shandong Province alone has an area of ​​nearly 10 million mu of fruit trees, including more than 4.6 million mu of apples and 550,000 mu of grapes. More than 70% of the orchards are built on relatively barren land such as mountains and river beaches, but the income per mu is food crops. several times, even dozens of times. Due to the long-term lack of mineral and organic fertilizer input, the phenomenon of soil nutrient deficiency has become more and more serious, resulting in frequent occurrence of various fruit diseases. The loss is more than 10%, and even 40% in serious areas. Therefore, it is urgent to develop a low-cos...

Problems solved by technology

At the same time, due to the pollution of mariculture itself and the pollution caused by subsequent processing, it is becoming more and more serious

For example, the output value of shellfish aquaculture in my country has accounted for 1 / 3 of the entire marine aquaculture, but the remaining shells from shellfish harvesting have also increased sharply. In Shandong Province alone, there are more than 1 million tons of shellfish added every year. Most of them are accumulated on the coast, which not only causes secondary pollution, affects the quality of seawater, but also seriously damages the coastal landscape.

In addition, the by-products of seed cultivation, fish farming and seaweed farming and processing have also caused great pollution to the surrounding environment
