Problems solved by technology

Due to the small surface area of ​​sand particles, the water and fertilizer retention capacity of sand soil is poor, which limits the growth of plants
For this reason, the production of sandy land is increased by applying mineral fertilizers and irrigation in the dry season, thereby increasing economic benefits. The disadvantage is that due to the high permeability of sandy land, it is easy to leaching and losing plant nutrients, alkaline cations and toxic pesticides. Not only cause economic losses, but also cause soil acidification and groundwater pollution

Abstract

The intention discloses a sand water-saving and fertilizer-retaining material based on homologous plants and application of the sand water-saving and fertilizer-retaining material. The sand water-saving and fertilizer-retaining material is prepared by mixing the following raw materials in parts by weight: 70-75 parts of clay, 10-8 parts of straw biochar and 20-17 parts of decomposed cow dung. Thematerial provides a living environment for microorganisms required by plant growth by combining the clay, the straw biochar and the decomposed cow dung, and provides a sand-fixing and water-retainingenvironment for plant root growth. The synergistic water-saving and fertilizer-retaining functions of different treatment materials of the homologous plants are realized. The sand water-saving and fertilizer-retaining material is novel and unique, low in production cost, capable of effectively improving the water and fertilizer conditions of soil and beneficial to vegetation restoration and agricultural development of sand areas.

Description

technical field [0001] The patent of the present invention relates to the improvement of sandy soil, in particular to a water-saving and fertilizer-reserving material based on homologous plants and its application. Background technique [0002] With the development of urbanization in my country, there is a shortage of developable agricultural land, and deserts have become key areas for agricultural development. The development of sandy land must first solve the problem of water conservation and fertilizer conservation. The mechanical composition of sandy soil is 95.82% sand (2.0-0.02mm), 2.27% silt (0.02-0.002mm) and 1.19% clay (0-0.002mm). Due to the small surface area of ​​sand particles, the ability of sand to retain water and fertilizer is poor, which limits the growth of plants. To this end, the yield of sandy land is increased by applying mineral fertilizers and irrigation during dry seasons, thereby increasing economic benefits. Not only cause economic losses, but ...
