Composition and preparation method of compound fertilizer special for fruit tree

Abstract

The invention belongs to a microbe compound fertilizer special for fruit tree, in particular to a composition and a preparation method of the compound fertilizer containing active microorganism (silicate bacterium) special for fruit tree. The fertilizer is characterized in that the compound fertilizer is compounded by four components, including osmotolerant active microorganism fertilizer with decomposed phosphor and kalium, nitrogen-phosphor-kalium fertilizer, natural humic acid organism and microelement. The active microorganism in the composition can improve root vigor of a fruit tree, adjust crop development characters, enhance anti-disease and anti-drought resistance, and improve fruit tree quality; furthermore, the organism is also functional in improving soil constitution, revitalizing soil nutrient, enhancing fertilizer use ratio and decreasing fertilizer dosage.

Description

technical field [0001] The invention belongs to a special microbial compound fertilizer for fruit trees, and in particular relates to a production formula and a preparation method of a special organic-inorganic compound fertilizer for fruit trees containing active microorganisms (silicate bacteria). Background technique [0002] Since the founding of the People's Republic of China, my country's fruit trees have developed rapidly, especially in the past 20 years, and the cultivated area and fruit output have doubled. In 1957, the country's fruit tree planting area was 14.145 million mu, and in 1997 it reached 129.99 million mu, with a total output of 50.893 million tons, ranking first in the world. [0003] The cultivated area of ​​fruit trees expanded the fastest from 1984 to 1989, with an average annual increase of 19.82%. From 1991 to 1996, the average annual increase was 10.0%. 45.44 times that of 10,000 tons, and the per capita fruit possession is 44.8 kilograms, 14.9 t...

Problems solved by technology

However, the microorganisms in it cannot survive in the environment of high osmotic pressure. The chemical fertilizer part and the microbial fertilizer part need to be granulated separately and then mixed before use. Even this cannot completely guarantee that the biological activity of the microorganisms in the soil will not be affected by chemical fertilizers. Therefore, people look forward to an active microbial compound fertilizer that can withstand high osmotic pressure and can be compounded with chemical fertilizers. The granulation process is simple, easy to use, and the activity of microorganisms can still be guaranteed to be basically unaffected after long-term storage.
