Fertilizer rich in organic phosphorus and preparation method thereof

Abstract

The invention discloses fertilizer rich in organic phosphorus and a preparation method thereof. The fertilizer rich in organic phosphorus consists of the following components in parts by weight: 5-8 parts of bentonite, 4-7 parts of kieselguhr, 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 plant straw, 40-46 parts of ground phosphate rock, 4-7 parts of trace elements, 1-3 parts of fenaminosulf and 2-4 parts of chlorothalonil. In the fertilizer disclosed by the invention, due to the rich-phosphorus plants pueraria, miscanthus floridulus, artemisia subdigitata, green bristlegrass, indigofera tinctoria and lespedeza floribunda, the organic components of the fertilizer are increased, and the content of organic phosphorus in fertilizer is increased.

Description

technical field [0001] The invention relates to a fertilizer rich in organic phosphorus 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 ion...
