Special slow-release fertilizer taking biomass granular carbon as matrix for cherries and preparation method thereof

Abstract

The invention discloses a special slow-release fertilizer taking biomass granular carbon as a matrix for cherries and a preparation method thereof. Granular carbon prepared from agricultural abandoned biomass such as corncobs, peanut shells, rice husks and edible mushroom matrixes, taken as a matrix material, is compounded with nitrogen, phosphorus, potassium and other nutrient elements essential to the growth and development of the cherries by utilizing the microporous character and strong adsorption capacity of the granular carbon, so that the special slow-release fertilizer taking the biomass granular carbon as the matrix for the cherries is prepared. According to the invention, the biomass granular carbon is black biomass granular carbon particles formed after incomplete combustion of the agricultural abandoned biomass under a hypoxic condition, has various properties similar to those of soil humus, is very strong in capacity of adsorbing and maintaining nutrients and moisture, and furthermore, and has an effect of stimulating the growth of crops and a good slow-release performance for the nitrogen, phosphorus and potassium; the slow-release fertilizer prepared in such a way can effectively meet the requirements of the cherries for nutrients in the whole growth period after being applied once; and in addition, the special slow-release fertilizer has the characteristics of enhancing the soil fertility, improving the soil structure, being efficient and environmentally-friendly, and the like, thereby being beneficial to large-scale popularization and application in cherry production.

Description

[0001] technical field [0002] The invention belongs to the technical field of agricultural fertilizer production, in particular to a special slow-release fertilizer for cherries using biomass granular carbon as a substrate and a preparation method thereof. Background technique [0003] In cherry production, rational fertilization is an important measure to ensure yield and quality. Cherry has the characteristics of rapid growth and development, and needs concentrated fertilizer. From leaf unfolding, flowering, fruit development to maturity, they are all concentrated in the first half of growth, that is, from April to late June, while flower bud differentiation is concentrated in a short period after fruit picking. Therefore, the amount and distribution of nutrients supplied in the first half of growth have a great influence on the growth of cherry branches and leaves in early spring, flowering and fruit setting and fruit expansion. However, there are major problems in th...

Problems solved by technology

However, there are major problems in the fertilization of cherry trees at present: the first is that due to the low air temperature and soil temperature in early spring, the activities of the cherry root system are relatively poor, and the ability to absorb nutrients is weak, and the growth mainly depends on the nutrients stored in the tree body before winter; At present, the fertilizers used by cherries are mainly quick-acting chemical fertilizers, which dissolve quickly after being applied to the soil. If too much is applied at one time, it will not only damage the root system, but also easily cause the loss of nitrogen and potassium fertilizers and the fixation of phosphorus fertilizers by the soil, which will waste fertilizers and effectively affect cherries. decreased sex

In the burning season, there have been many incidents where flights could not land and highways were forced to close due to the smog in the sky, which not only wasted a lot of precious resources, but also brought serious pollution to the environment.
