Special fertilizer for oilseed rapes and preparation method of special fertilizer

Abstract

The invention discloses a special fertilizer for oilseed rapes and a preparation method thereof. The special fertilizer for the oilseed rapes is prepared from the following raw materials in parts by weight: 100 to 150 parts of straw powder, 30 to 50 parts of animal bone meal, 30 to 45 parts of rapeseed dregs, 20 to 35 parts of powdered rock phosphate, 15 to 30 parts of potassium superphosphate, 18 to 25 parts of humus, 4 to 8 parts of saccharides, 0.6 to 1.2 parts of EM stock solution, 10 to 18 parts of modified vermiculite power, 4 to 8 parts of borax, 5 to 9 parts of sepiolite powder, 0.5 to 1 part of plant growth regulator, 15 to 25 parts of traditional Chinese medicine dregs, and 2 to 4 parts of polyvinyl alcohol. According to the special fertilizer for the oilseed rapes and the preparation method thereof provided by the invention, the formula is reasonable, the occurrence rate of rapeseed diseases and insect pests is reduced, the stress resistance of the oilseed rapes is improved, meanwhile, the ecological environment of soil is improved, the damage of overmuch ground temperature change on root parts of the oilseed rapes is effectively relieved, the rapeseed quality is improved, and the yield of the oilseed rapes is increased.

Description

technical field [0001] The invention relates to the technical field of agricultural chemical fertilizers, in particular to a special fertilizer for rape and a preparation method thereof. Background technique [0002] Rapeseed is Brassicaceae, Brassica genus, annual plant, taproot system, erect stems, few branches, plant height 30-90cm. Rapeseed is one of the important oil crops in China. The oil content of the seeds is 33% to 50%, and the protein content of the cake is as high as 40%. The nutrients necessary for the normal growth and development of rapeseed include carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, Elements such as calcium, sulfur, iron, zinc, boron, and silicon are currently used frequently as conventional chemical fertilizers, which are labor-intensive, time-consuming, costly, and pollute the environment, which can easily cause soil compaction and affect the growth of crops. It pollutes the environment, and the cost is low, but there are problems ...
