Problems solved by technology
[0003] 1. The water conservation measures are not good. After the saplings are planted or during the tending period of the economic forest, the watering is mainly based on direct hole irrigation. Due to the lack of water conservation measures and the strong evaporation of water in the sandy land, the water is lost rapidly, which cannot meet the long-term water requirements of the saplings. Demand, not only cause a lot of water waste, the effect is not good
[0004] 2. Reasonable planting density is not arranged according to the amount of rainfall in the planting area, and the tree species are different, resulting in insufficient water supply, affecting tree growth, and resulting in weak natural regeneration ability
[0005] 3. The sandy land is extremely barren, and there is no timely supplement of nutrients during the growth period of young trees, resulting in poor growth
[0006] 4. In recent years, the sand-covered afforestation promoted in some places uses ordinary agricultural film, which has low degradability and often causes secondary pollution of sandy land.

Embodiment
[0021] Such as figure 1 figure 2 As shown, build a tree planting pit 2 on the sandy land, with a depth of 1m and a diameter of 1m, and a ridge of 0.2m high should be built with soil around the pit. The density depends on the local rainfall. If the local annual rainfall is ≤400mm, the appropriate density is 3m×3m; if the rainfall is ≥400mm, the appropriate density is 3m×2m. Before planting trees, spread a layer of degradable plastic base film 6 on the lower layer of the tree planting pit 2, and then spread 10-20cm thick crop straw 10 to increase soil organic matter content and store water, plant 1a-year-old apricot tree saplings, and cover them with sand after planting Soil 11, the covering soil surface will be 20cm lower than the pit ridge, lay degradable plastic film 8 on it, compact with sand 9, punch a 0.5cm diameter drip irrigation hole 7 in the depression of degradable plastic film 8, and pass through The water pipe 3 leads the diammonium phosphate nutrient solution wi...

The invention discloses an environment-friendly method for drought-resistant afforestation on sandy land, which comprises the following steps: (1) excavating planting pits on sandy land and determining the concentration of the pits according to local rainfall; (2) laying a layer of degradable plastic film at the bottom of each pit, scattering a layer of crop straw on the film, and planting saplings; (3) covering degradable agricultural films after planting, covering sand on the films, and excavating an irrigation hole at the lowest concave position; (4) preparing diammonium phosphate water solution to be filled in an irrigation tank, and leading water to the irrigation hole through a water-leading pipe; and (5) in watering the saplings, inserting the outlet of an irrigation pipe into the irrigation hole, opening a water-control valve to irrigate, and controlling the flow rate at a certain speed.
Description
technical field [0001] The invention relates to an environment-friendly and drought-resistant afforestation method in sandy land. Background technique [0002] The sandy soil has large particles, is dry and barren, and rainfall is very easy to infiltrate and lose, resulting in a shortage of soil moisture. The shortage of soil moisture is the main factor restricting the growth of young forests, often resulting in low survival rate of afforestation, slow growth of trees, and natural regeneration of forest stands The capacity is reduced, and the benefits of economic forests are not high. It can be known from data review that in recent years, sandy land afforestation techniques popularized in various places, such as: sandy land afforestation technology in Dayulinkeng, sandy land afforestation and mulching technology, etc., are all simple trimming of sandy land to facilitate interception or retention of rainfall. Its technical content is low, and the following problems generally...
