Special fertilizer for mulberry trees and preparation method thereof

Abstract

The invention provides a special fertilizer for mulberry trees, belonging to the technical field of organic fertilizers. The fertilizer comprises the following raw materials in parts by weight: 80-100 parts of fermented poultry and livestock excrement, 30-50 parts of humic acid, 60-80 parts of silkworm excrement, 20-30 parts of weathered coal, 1-3 parts of boron fertilizers, 3-5 parts of ferrous sulfate, 5-10 parts of ammonium molybdate, 30-50 parts of river mud, 5-10 parts of EM (effective microorganisms) and 50-80 parts of waste tea dregs. The special fertilizer for mulberry trees is reasonable in proportioning, is nutritious and efficient, can fully provide the nutrient elements required for growth of the mulberry trees, is beneficial for the mulberry trees to absorb, and has the effects of preventing soil hardening and greatly increasing the leaf forming quantities of the mulberry trees.

Description

Technical field [0001] The invention relates to an organic fertilizer, in particular to a special fertilizer for mulberry and a preparation method thereof. Background technique [0002] The site conditions of mulberry fields in my country are generally poor. Silkworm farmers prefer to apply nitrogen fertilizer for a long time and ignore the input of organic fertilizer. In addition, for a long time, the soil management has adopted the clear tillage system and multiple leaf picking every year, which takes away a lot of nutrients and insufficient input of external organic matter. , Resulting in obvious degradation of soil fertility, and the organic matter content of mulberry garden soil is generally not high. Promote the combined application of organic and inorganic fertilizers to meet the normal operation of microbial carbon metabolism, ensure that a certain amount of newly formed humic acid is formed in the soil of the mulberry field every year, and promote the activation of t...

Problems solved by technology

However, long-term use will damage the soil aggregate structure, which will easily cause soil compaction and soil hardening, which will affect the growth of crops and the decline in quality, resulting in a vicious circle

At the same time, although the organic fertilizer is rich in organic matter, the release of nutrients is slow, resulting in slow absorption of crops, low fertilizer efficiency, and no effective balance between various effective nutrients. Due to the unscientific fertilizer formula for crops, the yield of crops is not high and the quality is also low. not improved
