Fertilizer slow-release device and method capable of retaining rainwater for landscaping

Abstract

The invention discloses a fertilizer slow-release device and method capable of retaining rainwater for landscaping, belongs to the technical field of landscaping, and aims to solve the problems that the growth heights of plants are uneven, fertilizer resources are wasted and landscaping construction is not facilitated due to the fact that one part of soil is lack of nutrition and the other part of soil is excessive in nutrition. According to the invention, the principle of communicating vessels is utilized, mixed liquid flows into the slow-release discharging cavity along the small liquid flowing grooves, liquid in the fertilizer storage cavity and liquid in the slow-release discharging cavity are kept flush, and the mixed fertilizer liquid permeates into soil along the slow-release pores to provide nutrition for the soil; rainwater flows into the guide flow cavity along the filter screen plate, the filter screen plate intercepts solid impurities, the rainwater enters the fertilizer storage cavity through the guide flow cavity, the rainwater and fertilizer blocks which are not completely dissolved before form mixed liquid again, and then nutrient supply to soil is facilitated through slow-release fine holes again.

Description

technical field [0001] The invention relates to the technical field of landscaping, in particular to a fertilizer slow-release device and method for retaining rainwater used in landscaping. Background technique [0002] Fertilizer refers to a class of substances that provide one or more essential nutrient elements for plants, improve soil properties, and increase soil fertility levels. It is one of the material bases of agricultural production, mainly including ammonium phosphate fertilizers, water-soluble fertilizers with a large number of elements , medium element fertilizer, biological fertilizer, organic fertilizer and multi-dimensional field energy concentrated organic fertilizer, etc. [0003] In the process of landscaping construction, fertilizer plays a vital role in the growth of green plants. If the fertilizer is directly buried in the shallow surface of the soil, the volatility of the fertilizer is relatively fast, and the soil is easily washed away in rainy weath...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a fertilizer slow-release device and method for landscaping that can retain rainwater, which solves the problem that in the process of landscaping construction in the background technology, fertilizers play a vital role in the growth of green plants. Covered in the shallow surface of the soil, the volatilization of the fertilizer is fast, the soil is easily washed away in rainy weather, the fertilizer is easy to be lost, and the utilization rate of the soil is low, and because the plant growth cycle requires different levels of nutrients, the staff must Fertilize the plants regularly, but some of the fertilizers sprayed in the early stage are completely absorbed, and some remain on the soil, but the amount of fertilizer applied is the same in each soil area, resulting in a lack of nutrients in some soils and excess nutrients in some soils. Not only is it easy to cause uneven plant growth heights, but it is also a waste of fertilizer resources, which is not conducive to the construction of landscaping
