Problems solved by technology

However, in the process of planting Haloxylon in frontier desert areas with wind and sand, the survival rate of transplanted seedlings for afforestation is only about 10%. Success, severely limited the development of Haloxylon and related industries
[0004] In order to improve the survival rate of Haloxylon seedlings transplanted for afforestation, most of the existing technologies transform the afforestation land when transplanting Haloxylon seedlings. The improvement methods include plowing the land, fertilizing and placing nutrient substrates, etc., such as the Haloxylon disclosed by Zhang Zhenrong and Wang Rongna. Artificial cultivation technology, in the incomplete soil preparation technology, only discloses the specific method of hole planting, although its planting effect is improved compared with traditional planting, but due to the influence of soil conditions in sandy areas, the improvement effect is not obvious; patent CN 104429802 A discloses a method for afforestation of Haloxylon-free vegetation on heavy clay soil in arid areas, and discloses the method of "organizing the terrain into a water collection tank, digging planting holes at the bottom of the tank and planting Haloxylon", although it solves the problem of sand frontier desert areas The problem of water shortage has improved the survival rate of Haloxylon saxaul, but due to large-scale land preparation, it will destroy the original ecology of the local area, and it will also have poor defense against rainy climates, which will easily cause root rot; The method of live-seeding afforestation in the growing season of Haloxylon in the sandy area discloses "including steps: 1) determination of the afforestation site; 2) laying drip irrigation pipes on the afforestation site; 3) irrigation before sowing; 4) sowing; 6) the planting method of "management after the second year of sowing", which improves the survival rate and preservation rate of Haloxylon plantation, and reduces the dependence on the team's weather, but this method increases the cost due to the laying of pipelines, and the soil in desert areas The lack of nutrients makes the growth of Haloxylon poor, and even affects the survival rate; CN 102577778 A discloses the dwarfing propagation technology of Haloxylon, which discloses "including steps: 1) transplanting inoculation with inoculation paper; 2) applying a small amount of farmyard manure or chemical fertilizer; 3) the planting method of marking the planting position, etc., which reduces the damage to the natural environment and wild vegetation by humans, and has a high planting success rate
However, the application of chemical fertilizers in the frontier desert area of ​​wind and sand not only destroys the original soil quality of the local soil, but also takes a relatively long time for the granular fertilizer to melt and absorb the crops, and is easily washed away when watering, and the fertilizer effect cannot be fully exerted; CN 1449649 A discloses a white shuttle The artificial planting method of Haloxylon disclosed the method of "cultivating Haloxylon in nutrition bags", which is obviously expensive and cannot be widely promoted
More importantly, there is a lot of wind and sand in the desert area at the frontier of wind and sand, and conventional fertilization methods, such as direct seeding, will easily blow away the topdressing fertilizer, and it is difficult to achieve substantive effects

Embodiment 1

[0027] The method for imitating ecological afforestation of Haloxylon in the frontier desert area of ​​wind and sand comprises the following steps:

[0028] 1) Forest land selection: 1000 mu of desert land with a soil moisture content of more than 2% and a salinity less than 2% in Jiebei Village, Hongshui Town, Jingtai County, Gansu Province was selected as forest land.

[0029] 2) Project implementation period: 2010-2015.

[0030] 3) Forest land treatment: Before soil thawing and planting in 2010, a planting belt with a depth of 20-30 cm and a width of 3 m was excavated in the afforestation site along the east-west direction. The original ecology of the desert area at the frontier of wind and sand is maintained between the belts.

[0031] 4) False planting: 2 days before planting, dig a false planting ditch with a width of 25-30 cm and a depth of 45-50 cm along the east-west direction. The south side of the false planting ditch is inclined at 45°. Put it in the ditch, squee...

Abstract

The invention discloses an imitative ecological afforestation method for Haloxylon ammodendron in a desert area of a sandstorm front, belonging to the technical field of plant cultivation. Desert land with a soil water content of 2% and above and a saline-alkali degree of less than 2% is selected as afforestation land. Cultivation belts are dug out along the eastwest trend of the afforestation land before the soil defreezing and plantation. In the cultivation belts, heeling-in ditches for heeling in are dug along the eastwest trend. Then direct-seeding forestation, irrigation, pest control, and enclosing management and protection are successively applied. Cultivation belts are dug out before plantation and afforestation, so that low survival rate and growth rate of Haloxylon ammodendron caused by the fact that weeds compete with Haloxylon ammodendron for water and fertilizer are avoided. At the same time, the original ecology is maintained by keeping certain space between every two cultivation belts and damage to local ecological environments can be prevented. Demands for water during plantation of Haloxylon ammodendron are sustained by the construction of reservoirs. Thus, the transplanting survival rate of Haloxylon ammodendron is remarkably increased to 90% and above in comparison with the traditional transplanting survival rate of about 10%.

Description

technical field [0001] The invention belongs to the technical field of plant planting, in particular to a method for imitating ecological afforestation of Haloxylon in desert areas at frontiers of wind and sand. Background technique [0002] Haloxylon is a small tree of the Chenopodiaceae Haloxylon genus, which is a national second-class protected plant. It has strong drought resistance, heat resistance, cold resistance, and salt tolerance. The salt content in the stems and branches is as high as about 15%. Strong, fast-growing, dense branches, well-developed root system, strong windbreak and sand-fixing ability, it is an excellent tree species for sand-fixing and afforestation in the arid desert areas of Northwest my country and Inner Mongolia. Haloxylon is a hard material with strong firepower, and it is a high-quality fuelwood.
