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

Abstract

The invention discloses a special slow-release fertilizer taking biomass granular carbon as a matrix for apples 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 apples 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 apples 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 apples 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 apple 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 apples using biomass granular carbon as a matrix and a preparation method thereof. Background technique [0003] Apple is a perennial fruiting tree, and a large amount of nutrients must be taken away every year when the fruit is harvested. If it is not supplemented in time, it will inevitably affect the tree vigor, resulting in a serious phenomenon of big and small years. Therefore, rational fertilization is one of the important measures to promote the robustness of apple trees, enhance resistance and prolong the fruiting period, and obtain high and stable yields. Nitrogen is a nutrient element that apple trees require in large quantities. Appropriate application of nitrogen fertilizer can increase the number of branches and leaves, enhance tree vigor and increase yield. Phosphorus and potassium are also n...

Problems solved by technology

With the continuous expansion of apple planting area, organic fertilizers can no longer meet the needs, and the repeated application of chemical fertilizers has the following shortcomings: first, it increases the labor intensity and labor costs of farmers; second, the regeneration ability of apple roots is not strong, and frequent digging Furrow fertilization will cut off a large number of roots and affect the absorption of nutrients

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.
