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 fertilizer technical field, more particularly relates to a rape special formula fertilizer. In the fertilizer, effective elements are calculated by weight percent of pure nutrient: nitrogen 23.0-16.0, phosphorus pentoxide 10.0-7.0, potassium oxide 16.0-9.0, calcium 5.0-2.0, magnesium 3.0-0.5, sulphur 6.0-2.0, zinc 0.5, boron 0.2 and molybdenum 0.03. Compared with the present technique, the rape special formula fertilizer of the invention has advantages of comprehensive nutrient content, reasonable match, accords with the nutrient absorption law of rape, can promote rape growth obviously and raise rapeseed output, increase economic benefits and improve rape nutriment quality. The rapeseeds increase production of 331-543 kg per hectare in testing area, increase income 759-911 RMB, absolute content of rapeseed oil increases by 2.03%, oleic acid content increases by 5.42%, the content of palmitic acid, eleaostearic acid, linolenic acid, peanut olefine acid reduces by 0.32%, 0.18%, 0.52% and 2.09% respectively. The fertilizer utilization efficiency is raised by 12.3%-14.5%.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special formula fertilizer for rapeseed. 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 million hectares. ...
