Problems solved by technology

[0005] (1) There is no supporting water diversion and water storage facilities, so that the water supply in the later stage of seedling growth is seriously insufficient
[0006] (2) Not paying attention to changing the micro-topography, not forming a larger catchment surface, so that the limited precipitation cannot gather around the roots of trees, resulting in ineffective evaporation of surface water
[0007] (3) The density of afforestation is too high, resulting in a serious shortage of soil moisture
[0008] Therefore, if the above-mentioned traditional conventional afforestation techniques are still used in the plantation process, the survival rate of the afforestation will inevitably be low, the growth of trees will be poor, and the growth rate will be low.

Embodiment 1

[0044] Implement the drought-resistant method of plantation and tending in the arid area of ​​Gansu, the specific implementation method steps are as follows:

[0045] (1), Jianshui collection system (as shown in Figure 1)

[0046] Use existing roads, or slope along the beams on the barren slope to the direction of confluence, and build the road confluence surface. When the existing road is used as the road collecting surface, the lateral ratio of the road collecting surface is 1 / 30-1 / 50, and the vertical ratio is 1 / 50-1 / 100.

[0047] Close to the collecting surface of the road, according to the perimeter of the collecting surface of the road, build a diversion channel with masonry structure, the diversion channel is 0.5m wide and 0.6m deep.

[0048] Construction of water storage facilities: build a water cellar with an interval of 400-500m and a distance of 5-10m from the aqueduct, as shown in Figure 2. 0.7m, built with bricks and 0.3-0.5m above the ground, the diameter of t...

Embodiment 2

[0059] In the arid areas of the north, the drought-resistant method implemented in plantation and tending, the steps are as follows:

[0060] (1), Jianshui collection system:

[0061] Where there are beams on the barren slope, the road collecting surface shall be built along the beam to the direction of confluence, which must be compacted. The dry bulk density of the compacted collecting surface shall not be less than 1.5t / m 3 . All the other are with embodiment 1;

[0062] The construction of water storage facilities: with embodiment 1.

[0063] (2) Construct the barren slope collecting surface (as shown in Figure 1).

[0064] Lay a plastic film on the tamped collecting surface, and lay a polyvinyl chloride film with a thickness of 0.2 mm on the collecting surface, and compact it with stones around; the rest are the same as in Example 1.

[0065] (3), the building of collecting pit: with embodiment 1

[0066] (4), water storage and moisture conservation measures: with em...

Embodiment 3

[0068] The construction of embodiment 3 water storage system

[0069] (1) Next to the diversion channel of the road collecting surface with little rainfall (rainfall of 10 mm within 24 hours or less than 2.5 mm within one hour), the workover type water cellar (see Figure 2), single Cellar capacity is 30~50m 3 .

[0070] The cellar body consists of three parts: cellar tube, dry cellar and water cellar. The dimensions of each part are as follows:

[0071] Cellar tube (upper ground cellar mouth, for water intake): diameter 0.6-0.7m, depth 1.5-2m;

[0072] Dry cellar (the part that does not store water): the upper part is connected with the cellar tube, with a depth of 2-3m. The diameter gradually enlarges downwards, until the diameter of the loose plate is 3-4m;

[0073] Cellar body (water storage part): 3-5m deep, the diameter gradually decreases from the loose plate downwards, and the diameter at the bottom is 2-3m;

[0074] Pit mouth: 0.6-0.7m in diameter, made of bricks ...

Abstract

The present invention provides a drought-resistant method for building and raising the artificial forest, the steps of which comprise: (1) the construction of the affluence surface; (2) the construction of affluence pit; and also comprise water-collection system. Adopting the drought-resistant method of the present invention that is used for building and raising the artificial forest can reasonably use the valuable waterfall resource in the arid region and in the semiarid region, adequately play the production potential of the land and maximally improve the growth of the tree, which provides a feasible method for maintaining the water and soil, resisting the drought, building the forest and raising the artificial forest in the arid region and the semiarid region in the north of China.

Description

technical field [0001] The invention relates to a drought-resistant method, in particular to a drought-resistant method for plantation and tending. Background technique [0002] In the arid and semi-arid areas of northern China, natural precipitation is the only water resource for trees to survive. However, under arid climate conditions, due to less precipitation, strong solar radiation and high wind speed, the potential evapotranspiration is very high. When the water supply intensity of the soil cannot meet the normal transpiration requirements of the trees, the trees will experience water deficit Deficiency can inhibit the progress of leaf photosynthesis, so that the survival rate of afforestation is low, and the phenomenon of "little old trees" is common. [0003] Only by adopting appropriate artificial flow collection technology to redistribute the extremely limited rainfall in space and time, so that the precipitation can be used efficiently. The use time of soil mois...
