Organic and inorganic compound fertilizer for improving folium mori yield and quality of mulberry

Abstract

The invention discloses an organic and inorganic compound fertilizer for improving folium mori yield and quality of mulberry. The organic and inorganic compound fertilizer is characterized by comprising 20-30% of organic matter containing more than 10% of humic acid, 25% of inorganic nutrient which contains 15% of N, 4% of P2O5 and 6% of K2O, biological active bacteria which comprise phosphate solubilizing bacteria, potassium bacteria and nitrogen-fixing bacteria, and microelements such as B, Zn, Mn, Cu and the like. The fertilizer provides proper inorganic nutrient proportion and microelements, and can fully meet the requirements of mulberry growth on nutrient substances; the contained organic matters and the biological active bacteria can improve the physicochemical property of the soil; soil nutrient release is facilitated; the prepared fertilizer particles have the function of slowly releasing the fertilizer effect; and the fermentation times can be reduced; the labor force is saved. By adopting the fertilizer, the folium mori yield and quality of the mulberry are obviously improved.

Description

technical field [0001] The invention relates to an organic-inorganic compound fertilizer for mulberry trees, in particular to an organic-inorganic compound fertilizer capable of improving the output and quality of mulberry leaves. Background technique [0002] Organic-inorganic compound fertilizers refer to compound fertilizers containing organic substances and inorganic nutrients. Most of the organic substances are processed organic fertilizers (such as livestock and poultry manure, urban waste organic matter, sludge, straw, wood chips, food processing waste, etc.) and substances containing organic matter (peat, weathered coal, lignite, humic acid, etc.), Others add microbial agents and substances that stimulate growth, which are called organic active fertilizers or biological slow-acting fertilizers; inorganic nutrients are mainly chemical fertilizers.

AI Technical Summary

Problems solved by technology

[0003] The site conditions of mulberry gardens in my country are generally poor. Sericulture farmers have applied nitrogen fertilizers for a long time, neglected the input of organic fertilizers, and harvested leaves many times a year, taking away a large amount of nutrients. The input of exogenous organic substances is insufficient, resulting in generally low organic matter content in the soil of mulberry gardens. , so the soil fertility of mulberry fields degrades obviously
