Embodiment Construction

[0032] The present invention will be further described below in conjunction with specific embodiments. The exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not as a limitation to the present invention.

[0033] A method for afforestation of willow cuttings in saline-alkali rainy season, comprising the following steps:

[0034] 1) Variety selection: select shrub willow Suliu 52-2, Suliu 2345, arbor willow Suliu 1011 or Suliu 1010 or one of other saline-alkali-tolerant fast-growing willow varieties;

[0035] 2) Forest ground water level control: For the plots that need afforestation, connect the internal and external drainage system of the forest land, control the ground water level below 0.6 meters when planting shrub species, and control the ground water level below 1 meter when planting tree species;

[0036] 3) Soil improvement: Start soil improvement 1 year in advance, apply cow dung with a fresh weight of more t...

Abstract

The invention discloses a coastal saline and alkaline land rain season willow root cutting forestation method. The coastal saline and alkaline land rain season willow root cutting forestation method includes variety selection, forest land underground water level control, soil improvement, bed manufacture, plastic film mulching, forestation and management. Compared with the prior art, the coastal saline and alkaline land rain season willow root cutting forestation method has the advantages that rainfall is large and forestation land is small in saline and alkaline stress effect in a rain season, and therefore willows easily sprout and grow, and then the willows can grow to be 1m high after the rain season is finished, the forestation land can be effectively mulched through proper close planting, salt surface infiltration action of the forestation land is inhibited, the forestation in the rain season can effectively avoid influences of spring drought, the root cutting forestation in the rain season has obvious advantages for coastal beach forestation land with no fresh water irrigated, and additionally by using the root cutting forestation, cuttings are completely inserted into soil, water retaining capacity of wickers is strong, and willow forestation survival rate on the coastal saline and alkaline land is improved, and furthermore when the root cutting forestation is used, forestation material consumption is small, the root cutting wickers are quick to collect and transport, forestation cost is low, close joining of all forestation environments is facilitated, and forestation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of afforestation, in particular to a method for afforestation of willow cuttings in rainy seasons in coastal saline-alkali land. Background technique [0002] The coastal saline-alkali land can use shallow soil layer, poor soil, compaction, poor air permeability, high soil salinity, and is easily affected by drought, flooding and typhoon, and lacks irrigation conditions. These unfavorable factors can directly or indirectly lead to Afforestation in coastal saline-alkali land has failed. Therefore, coastal saline-alkali land afforestation has always been a worldwide technical difficulty. In order to break through the "forbidden zone" of afforestation in coastal saline-alkali land, domestic and foreign scholars mainly conduct technical research in the selection of afforestation species and saline-alkali land improvement technology. [0003] 1. Selection of afforestation species [0004] There are relatively ...
