Problems solved by technology

[0005] The purpose of the present invention is to aim at the problem of low survival rate and preservation rate of seedlings after afforestation in arid desert areas, and proposes a structure and method for afforestation by accumulating water in arid desert areas to improve water supply conditions, thereby increasing the survival rate and preservation rate of seedlings. Preservation rate and water demand for later growth, to overcome the limiting factor of water shortage in afforestation, and prevent the development of desertification

Embodiment 1

[0028] The invention provides an afforestation structure for accumulating water in arid desert areas, such as figure 1 As shown, a preferred embodiment of the present invention is shown therein. The double-membrane water storage structure and process of the present invention fully utilize various water resources from three aspects of water storage, water collection and water retention, so as to achieve the purpose of continuous water supply and moisture conservation, and improve the survival and preservation rate of planted seedlings and the later stage. The water requirement for growth can overcome the obstacle of lack of water for afforestation seedlings to survive and survive, and meet the water requirements for later growth to a certain extent.

[0029] Specifically, the water-collecting afforestation structure includes a biodegradable film 4 laid on the bottom of the pit, a seedling 1 planted on the biodegradable film 4, a water tray 3 arranged around the seedling 1, and ...

Embodiment 2

[0041] The present invention also provides a method for afforestation by accumulating moisture in an arid desert area, comprising the following steps:

[0042] A. Level the tree planting work surface, dig planting pits as required before planting, and lay biodegradable plastic film 4 at the bottom of the pit. The surrounding area of ​​the biodegradable plastic film 4 is supported by soil blocks or crushed stones to form a pan shape, so that biodegradation The edge of the plastic film 4 is 8-12cm higher than the bottom.

[0043] Specifically, site preparation should be carried out in advance according to the planning scheme before construction. Dig pits as required before planting, and lay a biodegradable plastic film 4 with a thickness of 0.8s to 1.2s on the bottom of the pit. It is in the shape of a pan, with a rim height of about 10cm for water storage. Preferably, when laying the biodegradable plastic film 4, if there are sharp gravels at the bottom of the pit, a layer of...

Abstract

The invention relates to an afforestation structure and method for storing and collecting water in an arid desert area. The structure comprises a biodegradable mulching film laid at the bottom of a pit, a nursery stock, a water tray and a mulching film body laid on the ground around the nursery stock; the whole biodegradable mulching film at the bottom of the pit is in a pan shape, the water traywith the nursery stock in the pit as the center is in a funnel shape or a dustpan shape with a higher outer end and a lower inner end, an opening is formed in the center of the mulching film body which is pressed by soil or stones for fixation, and the mulching film body is covered with a plant straw layer. A double-film structure and a process are adopted, various water resources are fully utilized from the aspects of water storage, water collection and water conservation to achieve the purposes of continuous water supply and moisture conservation, the survival rate and preservation rate of the planted nursery stock are increased, the biggest constraint factor that afforestation in the arid area is in shortage of the water is overcome, and the requirement of the nursery stock for the water during growth in the later period is met to a certain extent.

Description

technical field [0001] The invention relates to the field of afforestation, in particular to a water-accumulating afforestation structure and method in an arid desert area. Background technique [0002] After the founding of the People's Republic of China, my country's greening and afforestation has achieved certain results. At present, the national forest coverage rate is 18.21%, an increase of about 5 percentage points compared with the 1980s. But this level is only 61.52% of the world average, ranking 130th in the world. In contrast, my country's forests have the weaknesses of insufficient total quantity, uneven distribution, and low quality. The overall function of the forest ecosystem is also very fragile, and there is a long way to go to protect and develop forest resources. [0003] Most of the Northwest China and North China mountainous areas are arid and semi-arid areas. At present, the arid and semi-arid areas account for about 52.5% of the total land area, and th...
