Filling body for stabilizing plant root system in desertification area and using method thereof

Abstract

The invention discloses padding used for stabilizing roots of plants in desertification regions and a use method thereof. The padding comprises a degradable inner wall, an outer wall, a planting hole and a bottom. A hollow structure between the inner wall and the outer wall and the planting hole are filled with filler made of the same material. The filler is prepared by mixing surrounding sand, sapropel, straw, local soil, humus and a microbial agent according to the volume ratio of 1:2:1:3:2:1. The top of the padding is open, the bottom of the padding is closed, and the planting hole allows the roots and stalks of the plants to penetrate. The filler can provide enough nutrients required by growth and development of the roots of the plants. The loose structure of the filler has a moisture storage function, the moisture retention time of the roots of the plants is prolonged, gas exchange between root systems and outside can be improved, the dissolved oxygen amount of the roots is increased, root respiration is promoted, a guarantee is provided for rooting, development and firm root taking of the root systems, the survival rate of the plants is increased, the vegetation coverage degree is improved, and the ecological functions of wind prevention and sand fixation, soil and water conservation and environment greening of the plants are played to the largest extent.

Description

technical field [0001] The invention relates to a filler body used for stabilizing plant root systems in desertification areas and an application method thereof, belonging to the field of desertification control. Background technique [0002] The United Nations Convention to Combat Desertification in Countries Occurring Serious Drought and / or Desertification, Especially in Africa states that desertification refers to arid, semi-arid and sub-humid conditions caused by various factors including climate variability and human activities. Land degradation in arid areas includes various forms of degradation such as desertification and salinization. my country is one of the countries with severe desertification in the world. According to the census of deserts, Gobi and sandy land in my country and the survey results of desertification, the desertified land area in my country is 2.622 million square kilometers, accounting for 27.4% of the national land area, and nearly 400 million ...

Problems solved by technology

[0004] However, because the growth of plants in desertified areas is limited by natural factors such as scarce rainfall, wind and sand, and poor soil, the root system of plants is unstable, the growth period is short, and the survival rate is low, which leads to the economic investment in afforestation projects being far greater than it should be.
