Mulberry fertilizer and preparation method thereof

Abstract

The invention provides a mulberry fertilizer and belongs to the technical field of organic fertilizers. The mulberry fertilizer is prepared from the following raw materials in parts by weight: 80-100 parts of chicken manure, 30-50 parts of humic acid, 60-80 parts of dry biogas residue, 20-30 parts of weathered coal, 1-3 parts of boron fertilizer, 3-5 parts of ferrous sulfate, 5-10 parts of ammonium molybdate, 50-70 parts of canal mud, 10-15 parts of EM bactericide and 80-100 parts of straws. The mulberry fertilizer is reasonable in proportioning and efficient in nutrition, is capable of sufficiently providing nutrient elements needed by the growth of mulberries, can be favorably absorbed by mulberries and is capable of preventing soil hardening; as a result, the leaf quantity of the mulberries is greatly increased.

Description

Technical field [0001] The invention relates to an organic fertilizer, in particular to a mulberry fertilizer 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 clearing system and the leaf picking multiple times every year, which takes away a lot of nutrients and the input of external organic matter is insufficient. , Leading to obvious degradation of soil fertility, and the organic matter content of mulberry orchard soil is generally not high. Promote the combined application of organic and inorganic fertilizers, so as to meet the normal operation of microbial carbon metabolism, to ensure that a certain amount of newly formed humic acid is formed in the soil of the mulberry field every year, and to promote the act...

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
