Special slow release fertilizer for tomato by using biomass granular carbon as matrix and preparation method thereof

Abstract

The invention discloses a special slow release fertilizer for tomato by using biomass granular carbon as a matrix and a preparation method thereof. Granular carbon prepared from agricultural wastes such as corn cobs, peanut shells, rice hulls, edible fungi matrix and the like are used as a matrix material; and based on the micro-pores and strong adsorption capability of the matrix material, the granular biomass carbon-based special slow release fertilizer for the tomato is prepared by compounding the matrix material and nitrogen, phosphorus, potassium and other nutritional elements required by growth and development of the tomato. The biomass granular carbon is black biomass granular carbon granules formed after the agricultural waste biomass is incompletely burnt under the low-oxygen condition, has multiple properties similar to soil humus and strong adsorption and nutrient and moisture holding capabilities, can stimulate growth of crops, and has good slow release performance on nitrogen, phosphorus and potassium; when the prepared slow release fertilizer is applied at one time, the requirements of the tomato for nutrients in the whole growth period can be effectively met; and the slow release fertilizer has the characteristics of increasing soil fertility, improving the structure of soil, realizing high efficiency and environment friendliness and the like, and is beneficial to large-scale popularization and application in the production of the tomato.

Description

[0001] technical field [0002] The invention belongs to the technical field of agricultural fertilizer production, and in particular relates to a tomato-specific slow-release fertilizer using biomass granular carbon as a substrate and a preparation method thereof. Background technique [0003] In tomato production, rational fertilization is an important measure to ensure yield and quality. Tomato is an infinite-growing crop, which can bloom and bear fruit continuously, and has a long period of time for stem and leaf growth and fruiting to proceed simultaneously. The vegetative growth and reproductive growth of tomato must be coordinated to achieve high yield and high quality. Otherwise, excessive nutrition, especially nitrogen, will easily cause fruit drop and yield reduction due to excessive plant growth; if the nutrition is insufficient, stem and leaf growth and reproductive growth will Competing for nutrients makes the fruit small and of poor quality. Tomatoes need a s...
