Lobster and rice co-culture ecological fertilizer

Abstract

The invention discloses a lobster and rice co-culture ecological fertilizer, which is prepared from the following components in parts by weight: 20 to 50 parts of water-soluble ammonium polyphosphate,10 to 20 parts of potassium chloride, 10 to 25 parts of urea, 2 to 10 parts of activated humic acid, 1 to 10 parts of modified sodium percarbonate, 1 to 10 parts of modified urea peroxide and 1 to 5parts of bioactive calcium. The invention aims to solve the problems of soil acidification hardening, organic matter content reduction, soil microorganism quantity reduction, water quality deterioration, lobster diseases, excessive heavy metals and the like caused by large-scale application of conventional compound fertilizers under a 'lobster-rice co-culture' mode. The invention provides the lobster and rice co-culture ecological fertilizer and a preparation method thereof so as to improve the soil environment, change water and increase oxygen, enhance the fertilizer efficiency period, promote the nutrient absorption of lobsters and rice and achieve the effects of increasing both production and income.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to an ecological fertilizer for co-culture of shrimp and rice and a preparation method thereof Background technique [0002] Rice occupies the most important position in my country's food crops, and it is also the food crop with the largest amount of nitrogen fertilizer input in my country. At present, in the process of rice cultivation in my country, the nitrogen utilization rate is 30%-35%, and the loss is as high as 50%. For a long time, my country has been continuing the traditional single planting mode of rice, and increasing the yield of rice through a large amount of chemical fertilizers and pesticides, forming a vicious cycle of high production costs and low economic benefits, which has brought many problems such as non-point source pollution of rice fields , the safety and quality of rice cannot be effectively guaranteed, and the rice field ecosystem is seriousl...
