Embodiment 1

[0026] First, take 5 parts of defatted rapeseed cake, 18 parts of humic acid, 15 parts of amino acid, and 0.5 part of biological bacteria in parts by weight, mix them after crushing and carry out biological fermentation to obtain a combination of active organic substances, and set aside;

[0027] Secondly, take 32 parts of urea, 8 parts of diammonium phosphate, 20 parts of potassium sulfate, and 1.5 parts of trace elements by weight, and make an inorganic nutrient optimization formula according to scientific proportioning, for subsequent use;

[0028] Thirdly, mix the spare active organic substance combination and the optimized formula of inorganic nutrients, and then carry out secondary pulverization to obtain the mixture, which is ready for use;

[0029] Fourth, the mixture is subjected to high-speed centrifugal drying and humidity control, and the matrix composite technology is used to granulate it with a disc machine. After secondary centrifugal drying and screening, a new ...

Embodiment 2

[0040] First, take 15 parts of defatted rapeseed cake, 8 parts of humic acid, 5 parts of amino acid, and 1.5 parts of biological bacteria in parts by weight, mix and carry out biological fermentation after crushing to obtain a combination of active organic substances, and set aside;

[0041] Secondly, take 22 parts of urea, 18 parts of diammonium phosphate, 30 parts of potassium sulfate, and 0.5 part of trace elements by weight, and mix them into an inorganic nutrient optimization formula according to scientific proportioning, and set aside;

[0042] The third to fourth steps are the same as in Embodiment 1.

Embodiment 3

[0044] First, take 10 parts of defatted rapeseed cake, 13 parts of humic acid, 10 parts of amino acid, and 1 part of biological bacteria in parts by weight, mix them after crushing and carry out biological fermentation to obtain a combination of active organic substances, and set aside;

[0045] Secondly, take 27 parts of urea, 13 parts of diammonium phosphate, 25 parts of potassium sulfate, and 1 part of trace elements by weight, and mix them into an inorganic nutrient optimization formula according to scientific proportioning, for subsequent use;

[0046] The third to fourth steps are the same as in Embodiment 1.

[0047] The new special blended fertilizer for oilseed rape of the present invention is mainly used for oilseed rape, and can also be used for grains, vegetables, melons and fruits, fruit trees and other crops. When applying, the base fertilizer is mainly used for deep application, and it can also be used as top dressing or foliar spraying with water.

Abstract

The invention discloses a special novel blending fertilizer for rape, and a preparation method thereof. The fertilizer is prepared by mixing the following raw materials, by weight, 22-32 parts of urea, 8-18 parts of diammonium phosphate, 20-30 parts of potassium sulfate, 5-15 parts of amino acids, 5-15 parts of degreased rapeseed cakes, 8-18 parts of humic acid, 0.5-1.5 parts of biological fungi and 0.5-1.5 parts of trace elements. The fertilizer has the advantages of strong specificity, high fertilizer efficiency, great improvement of the output, the quality and the oil productivity of rape, and the like, can improve the rapeseed output per 666.7m<2> by 10-20% and the oil productivity by 5-10%, and can greatly improve the quality. The fertilizer has better fertilizer efficiency than other common composite fertilizers, is especially suitable for the plantation of rapes in the regions of central south and south of the Yangtze River, and has very substantial effects. The fertilizer can be used for rapes, and can also be used for economic crops comprising grain and oil crops, fruit trees, vegetables and tea leaves. The fertilizer can be applied mainly through furrow application, can be broadcasted as an after fertilizer or is spread on the blade surfaces with water.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a novel blended fertilizer specially used for rape and a preparation method thereof. Background technique [0002] Rapeseed is the oil crop with the largest planting area in my country. Rapeseed is an important source of edible vegetable oil and feed protein in my country. Rapeseed oil is the largest edible vegetable oil produced in China, accounting for more than 40% of domestic edible vegetable oil. my country is a major producer of rapeseed, with an annual planting area of ​​9.3 million hectares and a total output of 19 million tons. The area and output of rapeseed have long been ranked first in the world, accounting for about 30% of the world. Promoting the comprehensive, coordinated and sustainable development of the rapeseed industry, restoring and improving the comprehensive production capacity of rapeseed is of great significance for ensuring the effectiv...
