Method for desert forestation

Abstract

The invention discloses a method for desert forestation. The method comprises the following steps including 1, water source preparation, namely a plurality of wells are drilled in the desert forestlands; 2, seedling preparation, namely for Salix psammophila cuttings, the branches of 1.2 to 1.5 m in length and more than 0.8 cm in diameter are selected, the gathered seeding blanches are soaked in water to absorb water, and for poplar or hankow willow cuttings, the seedlings of 3.5 m in height and more than 3 cm in diameter at breast height are selected and soaked in water prior to planting to absorb water; 3, water flush forestation planting, namely water in the wells is pumped out through a centrifugal water pump, so that the sandy soil around the seedlings is flushed into gaps through water to fill and seal the gaps, and the seedlings are watered fully. The desert forestation procedures can be finished within 30 to 50 seconds by utilizing the method provided by the invention, the forestation survival rate achieves 90%, and the three-year conservation rate reaches more than 80%.

Description

technical field [0001] The invention relates to a desert afforestation method. Background technique [0002] In arid and semi-arid areas, mobile sand dunes in desert sand, bare sand and other desert areas with harsh natural conditions, the survival rate and forestation rate of afforestation have always been the bottleneck problem that restricts the effect of afforestation, and it is also a technology that afforestation workers have been paying attention to. question. Moisture in the above-mentioned areas is an important factor affecting the low survival rate of afforestation. If irrigation is carried out, the transportation and implementation conditions will be very difficult, and it will increase the cost of afforestation. [0003] In the past, the afforestation technology is to first prepare the land, dig the planting holes manually or mechanically, and then complete the whole afforestation process through the processes of planting seedlings, covering soil, and watering. ...

Moisture in the above-mentioned areas is an important factor affecting the low survival rate of afforestation. If irrigation is carried out, the transportation and implementation conditions will be very difficult, and it will increase the cost of afforestation

[0003] In the past, the afforestation technology was to prepare the land first, dig the planting holes manually or mechanically, and then complete the entire afforestation process through the processes of planting seedlings, covering soil, and watering. The conventional afforestation process is complicated and cumbersome, and the survival rate and preservation rate of afforestation are low.

[0004] Although the high-pressure water drilling technology of combined wells for planting seedlings has been reported, it is often difficult for the tree species after afforestation to survive and become forests due to wind erosion in the mobile sand dune area, resulting in a significant decline in the afforestation effect in the later period
