Microcapsule fertilizer rich in phosphorus and preparation method thereof

Abstract

The invention discloses a microcapsule fertilizer rich in phosphorus and a preparation method thereof. The microcapsule fertilizer rich in phosphorus consists of the following ingredients in parts by weight: 5-8 parts of bentonite, 4-7 parts of diatomite, 5-8 parts of high-calcium clay, 3-6 parts of zeolite, 14-18 parts of ammonium sulfate, 13-15 parts of diammonium phosphate, 4-6 parts of fulvic acid, 20-25 parts of crop stalks, 40-46 parts of ground phosphate rocks, 4-7 parts of microelements, 1-3 parts of fenaminosulf and 2-4 parts of chlorothalonil. According to the fertilizer, as plants highly rich in phosphorus, such as kudzu vine, miscanthus floridulus, artemisia subdigitata, green bristlegrass, indigofera tinctoria and lespedeza floribunda, are adopted, the content of organic ingredients and organic phosphorus in the fertilizer increases.

Description

technical field [0001] The invention relates to a phosphorus-rich microcapsule fertilizer and a preparation method thereof. Background technique [0002] At present, due to the increasing use of chemical fertilizers, most of the varieties used are unit nitrogen fertilizers, while the use of multi-element fertilizers containing phosphorus, potassium and other elements is relatively small, resulting in soil hardening and weakening of the ability to retain water and fertilizer. Single pursuit of high-nitrogen or high-potassium compound fertilizers is blind, low utilization rate, and some even result in low quality agricultural products, endangering the health of consumers; poor physical properties, dusty, not compressive, agglomerated, and inconvenient Storage, transportation and fertilization. Generally, the utilization efficiency of inorganic fertilizers is low. The main reason is that after inorganic fertilizers are applied to soil or water, they are easily fixed by metal i...

Problems solved by technology

[0002] At present, due to the increasing use of chemical fertilizers, most of the varieties used are unit nitrogen fertilizers, while the use of multi-element fertilizers containing phosphorus, potassium and other elements is relatively small, resulting in soil hardening and weakening of the ability to retain water and fertilizer. Single pursuit of high-nitrogen or high-potassium compound fertilizers is blind, low utilization rate, and some even result in low quality agricultural products, endangering the health of consumers; poor physical properties, dusty, not compressive, agglomerated, and inconvenient Storage, Transport and Fertilization

Generally, the utilization efficiency of inorganic fertilizers is low. The main reason is that after inorganic fertilizers are applied to soil or water, they are easily fixed by metal ions such as calcium, magnesium, iron, and aluminum, and are easily adsorbed by clay mineral particles, thereby reducing fertilizer efficiency and affecting environmental pollution

Excessive addition not only increases the cost of chemicals, but also the content of inorganic phosphorus in the effluent is likely to exceed the standard
