Problems solved by technology

On the one hand, the utilization rate of fertilizers is low, which will pollute the soil and water; on the other hand, some chemical elements in mulberry leaves exceed the standard, which often leads to problems such as reduced cocooning rate or increased mortality of young silkworms, which affects the quality of silk

Embodiment 1

[0018] The optimal combination of mulberry foliage fertilizer is: potassium fertilizer, 5% (weight); Nitrogen fertilizer, 5% (weight); Phosphate fertilizer, 2.5% (weight); Humic acid, 25% (weight); Compound amino acid chelated trace elements, 25% (weight); growth regulator, 2500 ng / g (weight); carrier, 22.5% (weight).

[0019] The technique of producing mulberry leaf fertilizer of the present invention is:

[0020] (1) Take 100kg feather meal and place it in 0.5m 3 Add 200L of 30% hydrochloric acid to the enamel reactor, condense and reflux hydrolysis for 22 hours at a temperature of 95°C, add ammonia to neutralize, and obtain a compound amino acid solution.

[0021] (2) Add equimolar trace elements to the obtained compound amino acid solution, and perform chelation reaction at a temperature of 80° C. for 2 hours. Concentrate by evaporation to half the volume of the reaction solution, add 50 kg of carrier and mix well. Then the mixture is dried at 90°C and pulverized to obt...

Abstract

The invention relates to a mulberry foliar fertilizer as well as a preparation method thereof, which belong to the organic fertilizer field. The foliar fertilizer is mainly prepared by nutritive elements required by mulberry, amino acid, humic acids and a plant growth regulator. The results of experiments in mulberry field show that the usage of the mulberry foliar fertilizer can increase the mulberry leaf output by 30 percent, extend the mulberry growth time in autumn, and be favorable for improving the quality of silkworm cocoons, and the production of silkworm cocoons is increased by about 20 percent.

Description

technical field [0001] The invention belongs to the field of organic fertilizers, and relates to a mulberry leaf fertilizer and a preparation method thereof. Background technique [0002] The nutrients needed for the growth of mulberry trees mainly absorb the fertilizer in the soil through the root system, but the soil fertilization is affected by climate, environment and growth stage, etc., especially in the long-term drought in autumn in Guangxi, the soil is hard, and it is difficult to fertilize the roots, which is easy to cause The quality of mulberry leaves is poor, aging and falling off. Mulberry foliage fertilizer not only supplements the nutrients needed by mulberry trees, but also makes up for the lack of soil fertilization, and improves the yield and quality of mulberry leaves. At present, the foliar fertilizers used for mulberry trees mainly include: one is the inorganic salt nutrition type: this kind of foliar fertilizer is made by mixing various nutrients. Suc...
