A fertilizer slow-release device suitable for deep and shallow soil root diffusion

Abstract

The invention discloses a fertilizer slow-release device applicable to soil stepped root diffusion, which belongs to the technical field of fertilizer application. By adopting the combination of drip irrigation and fertilizer slow-release agent, the fertilizer slow-release agent dissolves and releases slowly after meeting water to obtain a fertilizer solution , the fertilizer solution is introduced into the elliptical slow-release box and the elliptical quick-release box with the water flow, and the capillary slow-release diffuser distributed at the bottom of the elliptical slow-release box is used to carry out capillary drainage and diffusion of the fertilizer solution to the depth of the soil, and introduce it into the elliptical The fertilizer solution in the shaped quick-release box quickly diffuses in the shallow soil layer through multiple osmotic bulges, and its release speed and amount are much greater than the release effect of the capillary slow-release diffuser, so it is more suitable for fertilization of some shallow-rooted crops. At the same time, the tops of the multiple elliptical quick-release boxes are directly connected to the auxiliary drip irrigation pipe through the second dropper. When fertilization is not being applied, the valve at the first dropper can be closed to irrigate the soil.

Description

technical field [0001] The invention relates to the technical field of fertilizer application, and more specifically relates to a fertilizer slow-release device suitable for deep and shallow soil root diffusion. Background technique [0002] Fertilizer is a kind of substance that provides one or more essential nutrients for plants, improves soil properties, and improves soil fertility. It is one of the material bases of agricultural production. Organic fertilizers contain various nutrients and rich organic matter. Promote microbial reproduction, improve soil structure, enhance soil fertilizer and buffer capacity, and stimulate crop growth. After applying organic fertilizer, it can loosen the soil, improve the ecological environment of the root system, and promote the development of the root system. Improve the waterlogging tolerance of crops. At the same time, after a variety of functional microorganisms contained in bio-organic fertilizers enter the soil, they will produce ...

Problems solved by technology

This traditional spraying fertilization method has certain defects: due to the excessive application speed, the fertilizer attached to the ground is likely to volatilize before the vegetation absorbs it, and it is difficult to be completely absorbed by the vegetation; in order to solve this problem, the existing technology also uses The fertilizer is applied by burying it, but this kind of excavation pit fertilizer is buried in the soil, the operation labor intensity is high, the production efficiency is low, the labor cost is high, and the amount of fertilizer application is uneven

For some shallow-rooted crops, the roots are mostly distributed in the shallow soil layer, and the soil at different depths requires different amounts of nutrients and water. The artificial burial fertilization method is single-handedly operated, and it is difficult to carry out "factoring" according to the needs of crops. Fertilize the ground"
