Moisturizing fertilizer with slow-release fertilizer efficiency

Abstract

The invention discloses moisturizing fertilizer with slow-release fertilizer efficiency, and belongs to the field of agricultural fertilizer. The moisturizing fertilizer is composed of a pellet core, a fertilizer layer and a percolation layer, and the pellet core is sequentially wrapped by the fertilizer layer and the percolation layer from inside to outside. The pellet core is made of high water-absorbing materials fully absorbing water, general chemical fertilizer is adopted in the fertilizer layer, and the percolation layer is made of degradable and soil-friendly materials with a permeation function. The moisturizing fertilizer with the slow-release fertilizer efficiency is low in production cost and high in production efficiency, can achieve the effects of achieving controlled release of the fertilizer and slow release of the fertilizer at the same time, has a certain moisturizing function on the surface layer of soil and is suitable for the soil in drought regions.

Description

technical field [0001] The invention relates to a slow-release fertilizer with moisturizing effect and belongs to the field of agriculture, in particular to an agricultural fertilizer. Background technique [0002] Some common fertilizers have low fertilizer absorption and utilization rate due to volatilization and denitrification after fertilization. Regular and continuous fertilization is required to meet the growth of plants. Some fertilizers may damage crops due to excessive local concentration during application. Undesirable consequences such as seeds, seedlings or burnt leaves, these fertilization processes not only increase labor intensity, but also increase labor costs. [0003] Slow-release fertilizers can change the traditional method of fertilization. It can realize one-time fertilization on various crops without topdressing, simplifies the fertilization procedure, and synchronizes sowing and fertilization, thereby greatly reducing agricultural labor intensity and...

AI Technical Summary

Problems solved by technology

[0006] But above-mentioned method has following defect: 1, price is high, is as many as 3-4 times of common fertilizer; 2, process is complicated, and polymerization time is long and production efficiency is low, and these cause slow-release fertilizer overwhelming majority to only be used for the high economic value. In the production of flowers, vegetables, lawns, etc., it limits its wide use; 3. It has high requirements for soil moisture and is not suitable for arid and water-scarce areas; 4. It only has the effect of unilateral slow-release fertilizer or controlled-release fertilizer
