Comprehensive improvement of saline-alkali land by planting new species of hybrid willow shelterbelt on coastal beaches

Abstract

The invention discloses a method for comprehensively improving a saline and alkaline land by planting a new species hybrid willow protection forest on a coastal mud flat, comprising the following steps of: preparing saline and alkaline land improvement materials and new species hybrid willow fast-growing fertilizers; taking comprehensive measures of new species hybrid willow protection forest planting; and managing the new species hybrid willow protection forest planting. According to the method disclosed by the invention, soil improvement materials are organically combined with the new species hybrid willow fast-growing fertilizers; the saline and alkaline land improvement materials can meet the requirements of the growth of new species hybrid willows on nutrients, are reasonably blended; the used materials are all mineral, agricultural and industrial wastes which have extensive source, and therefore low cost, high pertinency and improvement cost reduction are achieved; in addition, the invention is beneficial to the popularization and the generalization of a technology.

Description

technical field [0001] The invention relates to a method for comprehensively improving saline-alkali land by planting a new variety of hybrid willow shelterbelt on coastal beaches. Background technique [0002] Jiangsu is endowed with unique land reserve resources. The total area of ​​tidal flats in the province exceeds 10 million mu, and the total area of ​​unenclosed tidal flats is 7.5025 million mu, both accounting for about a quarter of the country's total. The extended coastline has prompted people to continuously reclaim tidal flats to make fields. However, in the process of tidal flat reclamation, many problems have been encountered, such as high salinity in tidal flats, difficult plant growth, lack of fresh water resources, heavy wind and sand, and a single ecological environment; due to high salinity, it is difficult for various salt-tolerant plants to grow. The lack of fresh water makes the surface of the bare tidal flats evaporate greatly, and sandstorms are easi...

Problems solved by technology

However, in the process of tidal flat reclamation, many problems have been encountered, such as high salinity in tidal flats, difficulty in plant growth, lack of fresh water resources, heavy wind and sand, and a single ecological environment; due to high salinity, it is difficult for various salt-tolerant plants to grow. The lack of fresh water makes the soil layer on the exposed tidal flat surface evaporate greatly, and it is easy to form wind and sand. The ecological environment is monotonous and deteriorating. Such a vicious circle has caused the development of tidal flats to progress slowly. Facing the resources that are at your fingertips, human beings can only hold back.
