Special biomass charcoal-based compound fertilizer for rapes and preparation method thereof

Abstract

The invention discloses a special biomass charcoal-based compound fertilizer for rapes. The biomass charcoal-based compound fertilizer comprises the following components in parts by weight: 11-15 parts of potash magnesium sulphate fertilizers, 15-20 parts of potassium chloride, 13-16 parts of fertilizer-grade dicalcium phosphate, 11-17 parts of urea phosphate, 25-30 parts of powdery urea, 5-13 parts of sorghum straw charcoal powder, 0.05-0.5 part of EDTA (Ethylene Diamine Tetraacetic Acid) chelated zinc, 0.05-0.5 part of EDTA chelated iron, 0.1-0.63 part of borax and 1-6 parts of auxiliary materials. The invention also discloses a preparation method of the special biomass charcoal-based compound fertilizer for the rapes. The special biomass charcoal-based compound fertilizer for the rapes, which is disclosed by the invention, can effectively improve and fertilize the soil, increase the content of soil organic matters, reduce the soil volume weight and enhance the moisture and fertility preserving capacity of the soil after being applied, is relatively high in fertilizer nutrient utilization efficiency and harmonious and lasting in nutrient element release, can be used for comprehensively and equivalently supplying the nutrients to the rapes, outstandingly increases the rape output, improves the rape quality and achieves an obvious economic benefit.

Description

technical field

[0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special biomass carbon-based compound fertilizer for rapeseed and a preparation method thereof. Background technique

[0002] Rapeseed is the most important oil crop resource in my country. The planting area and output of China rank first in the world. Its planting area has accounted for more than 40% of the total area of ​​oil crops, and it is also the oil crop with the fastest expanding planting area in the world. As the main oil crop in my country, the improvement of rapeseed quality and yield has attracted more and more attention. The use of agricultural chemical fertilizers occupies a very important position in the production of rapeseed in my country. Due to some unreasonable factors in the use process, not only the fertilizer The nutrient utilization rate is reduced, and the ecological environment including the soil environment has been seriously damaged....
