Biodegradable microspheres coating fertilizer

Abstract

The invention discloses a biodegradable microspheres coating fertilizer, which belongs to the technical field of fertilizer preparation. The biodegradable microspheres coating fertilizer comprises the following components by mass part: 30-35 parts of microspheres coating particles, 1-2 parts of borax, 1-2 parts of white copperas zinc sulfate, 8-11 parts of peat soil, 9-12 parts of river dry mud, 3-5 parts of magnesium oxide powder, 6-8 parts of powdered steatile, 20-33 parts of rock phosphate powder, and 15-25 parts of potassium ore powder. The microspheres coating fertilizer has the beneficial effect that according to different growth period and environment of crops, the microspheres coating fertilizer can adjust the nutrition element of the fertilizer in the coating for supplying the nutrition required by different crops, fertilizer dissolution rate and the growth requirement of the crops are consistent; the coating of the fertilizer can be automatically decomposed in soil, controlled release performance of the nutrient of the fertilizer can not be influenced after decomposition, cost is low, and the microspheres coating fertilizer has wide development prospect.

Description

technical field [0001] The invention relates to a biodegradable microsphere-coated fertilizer and belongs to the technical field of fertilizer preparation. Background technique [0002] China is a large agricultural country, and it is also the largest country in the use of fertilizers. The proportion of chemical fertilizers in agricultural production accounts for about 50%, but the utilization rate of fertilizers in our country is not high, only 30%, which not only leads to a huge waste of economic energy, but also causes Various environmental problems; therefore, slow and controlled-release fertilizer products have been launched in China. Controlled-release fertilizers have become the development direction of agricultural fertilizers in the future. Coating materials are also called coating fertilizers and film fertilizers. A layer of film makes the dissolution rate of fertilizer consistent with the growth demand of crops, so as to save fertilizer, improve fertilizer utiliza...

Problems solved by technology

[0002] China is a large agricultural country, and it is also the largest country in the use of fertilizers. The proportion of chemical fertilizers in agricultural production accounts for about 50%, but the utilization rate of fertilizers in our country is not high, only 30%, which not only leads to a huge waste of economic energy, but also causes Various environmental problems; therefore, slow and controlled-release fertilizer products have been launched in China. Controlled-release fertilizers have become the development direction of agricultural fertilizers in the future. Coating materials are also called coating fertilizers and film fertilizers. A layer of film makes the dissolution rate of fertilizer consistent with the growth demand of crops, so as to save fertilizer, improve fertilizer utilization rate and increase agricultural economic benefits. However, this material is difficult to degrade in soil, and the coating film is in the fertilizer nutrient After the release is complete, it remains in the soil; although some coating materials can be decomposed, the materials are difficult to obtain and the cost is high. In addition, the nutrient controlled release performance of the fertilizer will be affected because the membrane material decomposes in the soil; therefore , to develop a low-cost, coated fertilizer that can be degraded and does not affect the controlled-release performance of the fertilizer. It is a new research and development direction for controlled-release fertilizer manufacturers today, and it is also of great significance to the development of agriculture.
