A kind of biochar-based compound fertilizer special for rice and preparation method thereof

Abstract

The invention discloses a biomass carbon-based composite fertilizer specially used for rice. The biomass carbon-based composite fertilizer comprises the following components in parts by weight: 8-15 parts of a potash magnesium sulphate fertilizer, 9-14 parts of potassium chloride, 13-20 parts of fertilizer grade dicalcium phosphate, 20-27 parts of urea phosphate, 25-30 parts of powdered urea, 5-10 parts of sunflower straw charcoal powder, 0.1-1 part of sodium silicate, 0.1-0.5 part of EDTA (ethylene diamine tetraacetic acid) chelating zinc, 0.05-0.5 part of EDTA chelating iron and 1-7 parts of auxiliary materials. The invention also discloses a preparation method of the biomass carbon-based composite fertilizer specially used for rice. According to the biomass carbon-based composite fertilizer specially used for rice and the preparation method, the biomass carbon-based composite fertilizer specially used for rice is rich in nutrient substances; the nutrient elements can be released and coordinated for a long time; fertilization is implemented in a disposable manner, and secondary fertilization is not needed or the secondary fertilization is implemented a little; the utilization efficiency of nutrients of the fertilizer is high; the property of soil can be improved, and the soil fertility is improved; furthermore, the rice yield can be obviously increased; the biomass carbon-based composite fertilizer has obvious economical benefits.

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 rice and a preparation method thereof. Background technique

[0002] Paddy rice is called rice or rice after shelling the rice grains. Nearly half of the world's population feeds on rice. In the late last century, the average annual rice output in the world was about 400 billion kilograms, and the planting area was about 145 million hectares. 95% of the rice produced in the world is consumed by humans. Rice is also the main food crop in my country, and the improvement of rice quality and yield has attracted more and more attention.

[0003] The growth process of rice is divided into three periods: front, middle and back. The early stage refers to the period from transplanting to the end of division, that is, the vegetative growth stage of rice. At this time, the goal is to promote effective division of mil...
