Abstract

The invention discloses a special oilseed rape fertilizer and a preparation method thereof, belonging to the field of organic fertilizers. The special oilseed rape fertilizer comprises decomposed pigmanure and auxiliary materials dispersed in the decomposed pig manure, wherein the auxiliary materials comprise the following components in parts by mass: 7-12 parts of wormcast, 2-5 parts of fermented vinegar residues, 2.5-6 parts of tobacco stems, 0.05-0.1 part of magnetic chitosan microspheres, 1-3 parts of bentonite, 3-8 parts of a kiln ash potash fertilizer and 6-10 parts of ammoniated strawpowder. According to the invention, components are screened and proportioned to prepare the special oilseed rape fertilizer; the physiological activity of oilseed rape can be improved; the rejuvenation and growth of oilseed rape seedlings can be promoted; the utilization rate of nutrients in the fertilizer can be improved; the lasting period of the fertilizer can be prolonged; the nutrients required by the oilseed rape in the whole growth period can be met by applying the fertilizer once in the oilseed rape seedling period; the time and labor are saved; the effect of preventing diseases and pests is achieved; the occurrence rate of diseases and pests of the oilseed rape is reduced; and the yield and quality improvement of the oilseed rape are promoted.

Description

technical field [0001] The invention belongs to the field of organic fertilizers, in particular to a special fertilizer for rape and a preparation method thereof. Background technique [0002] Rapeseed is the oil crop with the highest oil production efficiency, and the rapeseed oil it produces accounts for more than 50% of the vegetable oil in China, occupying a very important position in my country's edible oil supply chain. At the same time, rapeseed is not only an important oil crop, rich in protein, but also a crop that can be used for energy, feed and nectar. Moreover, rape has a special function of using land and raising land, which has extremely high economic and comprehensive utilization benefits. [0003] With the growing area of ​​rapeseed year by year, it has become the most important oil crop in my country. However, in the process of planting rapeseed, due to blind fertilization and partial application of nitrogen fertilizer, it not only causes waste of fertili...
