Abstract

The invention relates to a biological slow-release compound fertilizer, which comprises the following components in percentage by mass: 1 to 50 percent of animal blood membrane-forming agent, 40 to 90 percent of inorganic quick-acting fertilizer and 5 to 10 percent of binding agent, wherein the animal blood membrane-forming agent comprises the following components in percentage by mass: 10 to 50 percent of animal blood solid matter or derivatives thereof, 1 to 10 percent of high polymer membrane-forming agent, 1 to 20 percent of high polymer slow-release agent and the balance of water; the animal blood solid matter is animal blood powder prepared by drying animal blood; and the derivatives of the animal blood solid matter are chemically-modified animal blood powder prepared by performing chemical modification on the animal blood powder by using high polymer materials. The animal blood membrane-forming agent is water-insoluble and has the slow-release performance. Results of plot experiments in farm fields show that the biological slow-release compound fertilizer has obvious yield-increasing effect on crops, and improves the economical characters of the crops, especially vegetablesand lawns.

Description

technical field [0001] The invention relates to a biological slow-acting compound fertilizer. Background technique [0002] In the past ten years, my country's total grain output has increased with the increase of chemical fertilizer application, but the yield increase rate per unit of fertilizer has decreased significantly with the increase of chemical fertilizer application. The reason is that the fertilizer utilization rate is low and the loss is serious. Long-term extensive use of inorganic quick-acting fertilizers such as nitrogen, phosphorus, and potassium has caused soil organic matter damage and soil compaction, and soil erosion has not only resulted in low fertilizer efficiency, but also caused algae reproduction caused by environmental eutrophication, which has caused great harm to the environment. destroy. During the "Tenth Five-Year Plan" period, my country conducted a lot of research work on the development and industrialization of new fertilizers, and achieved...
