Embodiment 1

[0037] (1) Dig deep on the saline-alkali ground to form a planting pit, the planting pit is cylindrical, with a diameter of 100cm and a depth of 90cm;

[0038] (2) At the bottom and the inner wall of the planting pit, lay two layers of isolation nets woven by reed straw that can permeate and ventilate respectively. The thickness of the isolation nets is 1.3cm, and the interval between the two layers of isolation nets is 8cm. The attapulgite ore powder filter layers for absorbing saline and alkali components are respectively filled in between;

[0039] (3) Place an isolation ring inside the isolation net, the isolation ring is cylindrical, with a diameter of 20 cm, fill the original soil of the saline-alkali land mixed with microbial bacterial agents between the isolation net and the isolation ring, and air to 2 days;

[0040] (4) Plant saplings. When planting, saplings are planted in the isolation circle, and the isolation circle is filled with a mixed matrix comprising organi...

Embodiment 2

[0046] The only difference from Example 1 is that the microbial bacterial agent includes rhizobium, Acinetobacter beizierii, Bacillus megaterium, Bacillus subtilis, Bacillus licheniformis with a mass ratio of 10:3:5:1:10:3 and Pseudomonas.

Embodiment 3

[0048] The only difference from Example 1 is that the microbial bacterial agent includes rhizobium, Acinetobacter beizierii, Bacillus megaterium, Bacillus subtilis, Bacillus licheniformis with a mass ratio of 5:5:3:4:5:8 and Pseudomonas.

Abstract

The invention discloses a method for improving the construction survival rate of a coastal saline-alkali land protection forest. The method comprises the following steps: deeply digging in saline-alkali land to form planting pits; two layers of separation nets are laid on the bottom and the inner wall of the planting pit respectively, and the space between the two layers of separation nets is filled with a filtering layer; an isolation ring is placed in the isolation net, the space between the isolation net and the isolation ring is filled with saline-alkali land original soil mixed with a microbial agent, and the saline-alkali land original soil is aired for 1-2 days; saplings are planted, during planting, the saplings are planted in the isolation rings, the isolation rings are filled with the mixed matrix, and then the isolation rings are taken away. According to the method, the microbial agent and the filter layer are prepared and jointly used for construction of the coastal saline-alkali soil protection forest, salt outside the planting pits can be prevented from entering the periphery of the root system by using the filter layer, and the salt content around the plant root system can be reduced in combination with improvement measures of the microbial agent in the planting pits on saline-alkali soil; the damage of initial salinity of the coastal saline-alkali soil to the root system is reduced, and the long-term survival rate of the protection forest is improved.

Description

technical field [0001] The invention relates to the field of saline-alkali land protection forests, in particular to a method for improving the survival rate of coastal saline-alkali land protection forest construction. Background technique [0002] Saline-alkali soil is a common name for a type of soil in which saline-alkali substances accumulate on the soil surface. It means that the salt or alkali substances contained in the soil affect the normal growth of plants. Salt desertification belongs to land degradation caused by chemical action, most of which are distributed in the northwest, north, northeast and coastal areas. The agricultural use of saline-alkali land is very difficult and brings serious harm. The use of saline-alkali land plants for afforestation and forestry development plays an important role in many aspects: ① It can expand forest coverage and improve the regional ecological environment; ② It can improve saline-alkali soil and expand cultivated land area...
