Fast afforestation method of tamarix chinensis at coastal saline-alkali soil

Abstract

The invention discloses a fast afforestation method of tamarix chinensis at the coastal saline-alkali soil. The fast afforestation method comprises the following steps of: planting one or a plurality of tamarix chinensis provenance forest belts which are vertical to the prevailing wind direction on the afforestation land and carrying out site preparation at a wind-power planting area on the downwind direction of the tamarix chinensis provenance forest belt by utilizing the characteristics of ultrastrong salinity-alkalinity resistance, small seeds, strong germination capacity, easy survival, irregularly-scheduled flowering, and the like of Tamarixps; and naturally planting and seedling at the wind-power planting area by means of the propagation of tamarix chinensis seeds by wind power, and accelerating the forest establishment by adopting field management measures. The surface scale afforestation of the tamarix chinensis is carried out on the coastal saline-alkali soil to form a fast afforestation technology of the tamarix chinensis at the coastal saline-alkali soil; and the fast afforestation method is simple, fast and economic, can provide a great deal of seedlings and is used for afforestation at other places.

Description

Methods of rapid afforestation and greening of tamarisk in coastal saline-alkali land technical field The invention relates to a greening technology for coastal saline-alkali land, in particular to a method for rapid afforestation and greening of tamarisk in coastal saline-alkali land. Background technique A large area of ​​coastal saline-alkali land (or coastal saline soil) is distributed in the coastal zone. The terrain here is low and flat, the drainage is not smooth, the salt source is sufficient, the soil has high salinity content, the soil structure is compacted, and the ventilation and air permeability are poor. In addition, the groundwater level is high and the mineralization is high. The groundwater is mainly soluble salt chloride and covered by natural vegetation. The rate is very low, the biodiversity is monotonous, and the ecological environment is extremely fragile. Coastal saline-alkali land is a very difficult site type for afforestation, and conventional ...
