Planting blanket used for original soil improvement of muddy coastal saline-alkali land

Abstract

The invention discloses a planting blanket used for original soil improvement of muddy coastal saline-alkali land. The planting blanket sequentially comprises a salt isolation layer (1), a water storage layer (2) and a planting layer (3) from bottom to top. The planting blanket is characterized in that the planting layer (3) comprises a planting matrix (3a) and plant seeds (3b) scattered in the planting matrix; and the planting matrix comprises, by weight, 20-30 parts of grass carbon, 30-60 parts of decomposed cow dung, 12-36 parts of decomposed plant straw, 10-20 parts of decomposed wood chips, 10-20 parts of wheat husks, 7-11.6 parts of coal ash, 15-25 parts of hill sand, 5-7 parts of decomposed phosphorus fertilizer, 5-7 parts of decomposed nitrogen fertilizer, 10-20 parts of desulfuration residues, 8-10 parts of decomposed of rabbit dung, 8-10 parts of zeolite powder, 20-30 parts of candy pomace and 15-20 parts of decomposed mushroom bag materials. The planting blanket is reasonable in structure arrangement, throttling and natural rainfall storage are achieved on the basis that salt is effectively isolated, various nutrients required by plant growth are provided, the planting blanket is used for original soil ecological green recovery of the muddy coastal saline-alkali land, and the effect is remarkable.

Description

technical field [0001] The invention relates to a planting blanket, in particular to a planting blanket used for improving the original soil of muddy coastal saline-alkali land, and belongs to the technical field of saline-alkali land improvement. Background technique [0002] The muddy coast is a low and flat coast composed of terrestrial silt and silt developed along the outer edge of the plain. It is the main coastal type of Liao, Tianjin, Hebei, Shandong Bohai Bay, Jiangsu, Shanghai, and Zhejiang coasts, and it is also the silt coast of my country. Centralized subdivision of tidal flats is also one of the important ways for coastal residents to expand cultivated land and afforestation through artificial ponds. Therefore, it is of great practical significance to do a good job in greening muddy coasts and improve the ecological environment in coastal areas. [0003] The soil of the muddy coast is mainly coastal saline soil, with deep soil layer, barren soil, weak soil enzy...

Problems solved by technology

And because of the coast, the amount of evaporation is large, and the salinity of the lower soil rises with the water, which can easily cause the surface soil to return to salt and alkali. The process of desalination and alkali washing is slow, and the soil shrinkage rate is large, which has become a limiting factor for the growth of various crops.

In addition, the soil is easy to harden, the soil has poor air permeability, poor drainage capacity, and insufficient water storage capacity. Plants are prone to die due to root rot, insufficient oxygen, excessive alkalinity or excessive drying, which is not conducive to plant growth.
