Composite organic fertilizer of waste oil residue and cake meal and its preparation method

Abstract

The invention discloses a composite organic fertilizer of waste oil residue and cake meal and its preparation method, the organic fertilizer is prepared from the following raw materials: by weight, 12-15 parts of the waste oil residue, 30-35 parts of soybean meal, 10-12 parts of medical stone powder, 10-12 parts of zeolite powder, 20-25 parts of oil shale powder, 2-3 parts of sophora flavescens powder, 1-2 parts of quisqualis powder, 10-12 parts of coleus blumei powder, 50-55 parts of manioca leaf powder, 30-35 parts of tea-leaf, 100-120 parts of vinasse, 40-50 parts of vinegar residue, 10-15 parts of edible fungus chaff, 30-35 parts of ammonium dihydrogen phosphate, 16-19 parts of potassium sulfate, 50-55 parts of ammonium bicarbonate, 3-4 parts of a multielement slow release fertilizer and 1-2 parts of an EM (Effective Microorganism) bacteria agent; according to the composite organic fertilizer, the soybean meal, the oil residue, the medical stone powder, the zeolite powder and the like contain large quantities of trace elements and plant chemical components, the contents of related beneficial components in crops can be increased by crop absorption, the nutrition and health care values can be increased, at the same time, the sophora flavescens powder and the quisqualis powder have bactericidal effects, can reduce agricultural crop diseases and insect pests, can reduce chemical pesticide application amount to promote environmental protection.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizers, in particular to a compound organic fertilizer of waste oil residue and cake and a preparation method thereof. Background technique [0002] At present, my country's agricultural population continues to decrease, and a large number of by-products produced by agricultural by-products, such as cake meal, waste oil residue, tea residue, distiller's grains, etc., have not been reasonably utilized. These components contain a large amount of chemical substances that are beneficial to the human body. It is a pity to waste. A large number of chemical fertilizers are used in rural crops, resulting in soil compaction, decreased fertility, reduced nutrients and lack of health care value in the cultivated crops, which are not conducive to human health. Therefore, the by-products of agricultural and sideline products are used to make fertilizers and apply them to crops. On the one hand, it is con...
