Green fertilizer and preparation method thereof

Abstract

The invention provides a green fertilizer which comprises Chinese prickly ash leaves, pomegranate leaves, cortex albiziae, worm damaged bamboo powder and periploca sepium. The preparation method of the green fertilizer comprises the following steps: I, preparing nano cellulose from a part of the worm damaged bamboo powder; II, dipping the cortex albiziae and the periploca sepium into a potassium chloride solution, performing drying, and performing crushing so as to obtain cortex albiziae powder and periploca sepium powder; III, cleaning the Chinese prickly ash leaves and the pomegranate leaves, drying the leaves in the air; IV, crushing the Chinese prickly ash leaves and the pomegranate leaves, mixing and stirring the leaves with the worm damaged bamboo powder in a ratio of 2.5-5, adding avinegar mother liquid, and performing sealed composting so as to obtain a primary composting substance; V, mixing and stirring the cortex albiziae powder and the periploca sepium powder, adding the vinegar mother liquid, and performing sealed composting so as to obtain a secondary composting substance; and VI, mixing and stirring the primary composting substance, the second composting substance and nano cellulose, adding the vinegar mother liquid, and performing sealed composting, so as to obtain the green fertilizer. The green fertilizer has integrated medicine effects and fertilizer effects, is safe and environment-friendly and free of toxic or side effect.

Description

technical field [0001] The invention relates to the technical field of green agricultural and forestry fertilizer processing, in particular to a green fertilizer and a preparation method thereof. Background technique [0002] Most of the fertilizers and pesticides used in my country's agricultural production are chemical fertilizers and chemical pesticides. While increasing my country's grain production year after year, chemical fertilizers and pesticides have also brought about major problems such as soil quality degradation, water pollution, and agricultural product safety. Long-term, large-scale, and irrational application of chemical fertilizers and excessive use of chemical pesticides have caused serious imbalances in the effective microbial flora and beneficial trace elements in the soil, and the continuous reduction of organic matter, which in turn leads to continuous acidification of the soil, continuous decline in soil production capacity, and more soil. "Thin", the...

Problems solved by technology

Long-term, large-scale, and irrational application of chemical fertilizers and excessive use of chemical pesticides have caused serious imbalances in the effective microbial flora and beneficial trace elements in the soil, and the continuous reduction of organic matter, which in turn leads to continuous acidification of the soil, continuous decline in soil production capacity, and more soil. "Thin", the more you plant, the more "hungry", and the direct consequence of the continuous decline in the comprehensive fertility of the soil is that the utilization rate of chemical fertilizers is decreasing, pests and diseases are intensified, and the soil's ability to supply fertilizer, water, and gas to crops is reduced. Ability to buffer against soil pollution, and resistance to pests and diseases are significantly reduced. In order to strive for high yields, only chemical fertilizers and pesticides are the escort, thus falling into a vicious circle
