Problems solved by technology

The survey shows that there are the following problems in the management of rapeseed fertilizer: (1) The blindness and randomness of fertilization are large, the effect of fertilizer input is poor, and the utilization rate of fertilizer is low
(2) The amount of fertilizer is low, and the proportion of nutrients is not coordinated. It is manifested as heavy nitrogen and phosphorus fertilizer, light potassium and medium and trace element fertilizer, which aggravates the imbalance of soil nutrients.
At the same time, there are still many problems in the application of trace element fertilizers such as boron
(3) Rapeseed special formula and special formula fertilizer are less used, and the industrialization of fertilization starts slowly

Abstract

The invention belongs to the technical field of fertilizers, and particularly relates to a special compound fertilizer for increasing rapeseed yield. The fertilizer is prepared from the following rawmaterials: urea or / and diammonium phosphate, diammonium phosphate or / and calcium superphosphate, potassium chloride, calcium superphosphate, calcium superphosphate or / and magnesium sulfate or / and zincsulfate monohydrate, magnesium sulfate, zinc sulfate hydrate, borax and ammonium molybdate. The special compound fertilizer is complete in nutrient content and reasonable in proportion, conforms to the nutrient absorption rule of rape rape, and can obviously promote rape growth, increase rapeseed yield, increase economic benefits and improve rape nutritional quality.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special compound fertilizer for improving rapeseed yield. Background technique [0002] Rapeseed is the main oil crop in my country. It provides more than half of the edible oil in my country, and it is also a potential bulk protein source next to soybean meal. Rapeseed production has an important impact on ensuring the supply of edible vegetable oil and feed protein in my country, improving food structure, and promoting the development of aquaculture and processing industries. At the same time, rapeseed is a crop that combines land use and land cultivation. Planting rapeseed plays an important role in protecting or even improving soil fertility and controlling soil-borne diseases, and is one of the important factors to promote the sustainable development of agriculture in my country. [0003] The perennial planting area of ​​rapeseed in my country is about 8 m...
