Abstract

The invention discloses a special biological slow-release fertilizer for oilseed rape and a preparation method of the special biological slow-release fertilizer. The special biological slow-release fertilizer is prepared from the following raw materials in parts by weight: 40-55 parts of urea, 25-35 parts of potassium chloride, 10-15 parts of monoammonium phosphate, 5-8 parts of ammonium chloride, 5-20 parts of humic acid, 8-12 parts of rice bran, 5-10 parts of soybean straw, 3-7 parts of cotton seed hull, 1-5 parts of soybean curb residues, 2-5 parts of bagasse, 3-6 parts of superphosphate, 10-16 parts of talcum powder, 1-3 parts of fish meal, 2-6 parts of monopotassium phosphate, 5-15 parts of plant ash, 0.1-0.2 part of colloid bacillus and 0.1-0.2 part of azotobacter. The special biological slow-release fertilizer disclosed by the invention is prepared according to nutrient uptake feature of oilseed rape and is reasonable in nutrient matching, the yield of the oilseed rape can be increased, and the planting cycle can be shortened; if the slow-release fertilizer is applied together with a biological bacterium, the available nutrient of soil can be increased, prevention and control on plant diseases and insects can be facilitated, and the whole ecological environment can be improved.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special biological slow-release fertilizer for rape and a preparation method thereof. Background technique [0002] The development of planting in agricultural production is inseparable from fertilizers. my country's agriculture has a long history of 10,000 years. In ancient times, manure was called manure, and fertilization became manure field. Fertilization of farmland in my country began around the Yin and Shang dynasties, mainly based on the unearthed cultural relics that had wooden tools made of river mud at that time, and the oracle bone inscriptions of the Yin and Shang Dynasties that had recorded the characters for feces and choke, and there were inscriptions that fertilization can increase production. [0003] Rapeseed, also known as oily cabbage, bitter vegetable, Latin name: Brassica campestris L. Cruciferae, Brassica plants, tender stems and leaves...
