Description

Method for introducing American bamboo willows to perform saline-alkali soil original soil greening
Technical Field
The invention relates to a method for greening saline-alkali soil, in particular to a method for conducting saline-alkali soil original soil greening by introducing American bamboo willow.
Background
With the rapid development of the economic society of China and the continuous expansion of the urban scale, the east coastal region such as the yellow river delta efficient ecological economic region of the Bohai sea, the Tianjin coastal new region, the Hebei Caofendin new region, the Liaoning coastal economic zone, the Shanghai Pudong new region of the Long triangle, the Jiangsu coastal economic zone and the like starts to develop to the coastal mudflat. In coastal areas of Xisung, large-scale development is actively underway. The development of the areas inevitably brings about the construction of a large number of urban landscaping projects. However, both intertidal zone tidal flat, sea withdrawal land, sea area plain and new peripherad land blown and filled by the peripherad in the Bohai region and new peripherad land in the Jiangsu and Zhejiang regions are coastal heavy saline-alkali land, and typical coastal muddy heavy saline-alkali soil is formed due to the existence of high underground water level, high underground water mineralization and high evaporation-precipitation ratio (evaporation amount: rainfall amount: 3.13: 1). Most of the land has the salt content of more than 1 percent, the vegetation is rare, the ecology is fragile, and the agricultural production and the landscaping are restricted.
At present, the greening of a plurality of related domestic cities such as Tianjin coastal new areas, yellow river delta areas, Hangzhou bay new areas and the like mostly adopts an engineering salt-avoiding measure of 'isolating layer + alien soil' to reduce the underground water level and the salt content of soil, and after the salt content of the soil is controlled to be below 0.4%, the construction of garden greenbelts is carried out. The above measures, although successful, also present serious problems. Firstly, the cost is extremely high, the maintenance cost is high, various hidden dangers are buried for the maintenance management in the later period, and a large number of fertile farmlands are destroyed every year due to the planting of the foreign soil (usually, 1 cubic meter of good planting soil needs to be dug from the existing farmland to be used as the foreign soil every time 1 square meter of greening is carried out on the saline-alkali beach). Because the land resources can not be regenerated, the currently generally adopted soil-changing greening method causes great damage to the existing cultivated land and ecological environment; secondly, the salt tolerance of some traditional planted salt-tolerant tree species is low, the landscape effect is difficult to persist, and the phenomena of 'green in one year, yellow in two years and entering the stove chamber in three years', even 'greening in spring, yellowing in summer and whitening in autumn' occur. The technology of 'original soil greening' which has low cost and accords with the development principle of sustainable landscaping career is gradually taken into consideration by people.
The American bamboo willow is introduced from the United states, and 1-4 level tests in 8 regions of the nation prove that the successful performance of the American bamboo willow in all aspects such as cold resistance, drought resistance, flooding resistance and the like far exceed the performance of most of fast-growing tree species in China at present.
