SEED CAPTURE APPARATUS FOR COASTAL BEACH BARE SALINE-ALKALI SOIL, AND APPLICATION THEREOF

摘要

A seed capture apparatus for coastal beach bare saline-alkali soil, and an application thereof. The seed capture apparatus for coastal beach bare saline-alkali soil comprises a fixed bracket (1). The fixed bracket (1) is in a shape of a bell mouth, the top surface is arched, the other three surfaces are flat, and bottom edges of the fixed bracket (1) are evenly equipped with insert nails. A capture net (2) is built in the fixed bracket (1), and the upper side of the front end of the capture net (2) is provided with a barrier grid brim (4). Biochar bags (3) are evenly distributed on the bottom surface of the capture net (2) and an undisturbed part of the ground, the biochar bags (3) are covered with soil, and the total distribution area of the biochar bags (3) is 8-15% of the area of the bottom surface of the capture net (2). The apparatus is reasonable in design, significantly changes the soil surface roughness, regulates the migration of water and salt, effectively improves single nutrient element conditions in the soil, has good seed interception effect, and significantly improves the preservation rate of shrub and herbaceous plant seedlings and the vegetation coverage rate.
