Formula of organic high-content slow release fertilizer and production method

Abstract

The invention relates to a fertilizer and a production method thereof, in particular to a formula of an organic high-content slow release fertilizer and a production method thereof. The formula comprises the following components in percentage content: 15 to 20 percent of silkworm pupa leftover, 20 to 30 percent of plant phosphoric acid, 20 to 25 percent of potassium ash, 10 to 20 percent of livestock and poultry feces, 5 to 10 percent of starch, 10 to 15 percent of potassium fulvate and 0.5 to 1 percent of trace element. The organic fertilizer is applied into soil to provide plant nutrients as carbon-containing materials with main functions and is processed by using biological substances, animal and plant wastes and plant residues, toxic and harmful substances therein are removed, a great amount of beneficial substances are contained, not only can comprehensive nutrients be provided for crops, but also the fertilizer efficiency is long, the fertilizer is slowly released, the situation of excess nutrients is avoided, the organic matters in soil can be increased and updated, the breeding of microorganisms is promoted, the physical and chemical properties and bioactivity of the soil are improved, the PH value is moderate and no pollution is caused to the soil and environment.

Description

technical field [0001] The invention relates to a chemical fertilizer and a production method thereof, in particular to a formula and a production method of an organic type high-content slow-release fertilizer. Background technique [0002] Chemical fertilizers refer to chemically manufactured or mined ore and processed fertilizers, also known as inorganic fertilizers, including nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, micro-fertilizers, compound fertilizers, etc. They have the following common characteristics: simple ingredients, nutrients High content; fast fertilizer effect, strong fertilizer; some fertilizers have acid-base reaction; generally do not contain organic matter, and have no effect of improving soil and fertilizing. There are many types of chemical fertilizers, and their properties and application methods are quite different. [0003] However, in the actual process of fertilization, although it can make the crops grow rapidly, it w...

[0003] However, in the actual process of fertilization, although it can make the crops grow rapidly, it will reduce the yield of the crops, weaken the production capacity of the crops, and reduce the immunity of the crops, making them vulnerable to pests and diseases, and causing excess nutrients in the land. Expansion of pollution through water, and the principle of chemical fertilizer is to provide a single nutrient element for rapid cultivation, so the release speed is very fast, most of the nutrient elements are not absorbed by the crops, but enter the land, destroying the nutrient balance of the land, and causing damage to the soil. land hurts a lot
