Slow-release fertilizer sand fixation brick and sand fixation sand-protecting barrier

Abstract

The invention discloses a slow-release fertilizer sand fixation brick and a sand fixation sand-protecting barrier built by the slow-release fertilizer sand fixation bricks and belongs to the field ofwind prevention sand fixation engineering. The slow-release fertilizer sand fixation brick includes a brick body with a holding cavity and a through-hole in the middle, the brick body is made by mixing clay and slow-release fertilizer, and the slow-release fertilizer mass accounts for 15-30% of the total mass of the brick body. The sand fixation sand-protecting barrier is built by using the slow-release fertilizer sand fixation bricks, the brick bodies are vertically assembled and placed in a desert greening project zone, the lower ends of the brick bodies are inserted at least 5 cm into desert, and then the sand fixation sand-protecting barrier is formed by sowing grass seeds or shrub seedlings in gaps formed among the holding cavities, the through holes and the adjacent brick bodies. Thesand fixation sand-protecting barrier can release nutrients slowly and effectively, and greatly improves the seedling emergence rate and the survival rate of plants; and the problems of desertification, desertification grassland water deficiency, nutrient deficiency, plant nutrient deficiency in the late stage of the long growth cycle and the like can be effectively solved.

Description

Technical field [0001] The invention relates to the field of wind-proof and sand-fixing engineering, in particular to a slow-release fertilizer sand-fixing brick and a sand-fixing sand barrier built with the slow-release fertilizer sand fixing brick. Background technique [0002] Land desertification and desertification are caused by natural and man-made factors, which have caused great harm to my country's economic and social development, and are one of the most serious ecological and environmental problems in my country. The core of the implementation of the wind-proof and sand-fixing project is to adopt a variety of technical measures to reduce the amount of quicksand in the airflow, weaken the wind speed near the surface layer, delay or prevent the forward movement of sand dunes, in order to achieve the purpose of weakening or avoiding the hazard of sandstorm. [0003] At present, the main shrub-grass sand barriers are mainly grass grid sand barriers, clay sand barriers, fence ...

Problems solved by technology

Therefore, the existing windbreak and sand-fixing greening and planting technology forms a sand-fixing belt with a long treatment cycle, poor stability, and poor sand control effect
