Description

Technical Field

[0001] The invention relates to the technical field of land desertification control, in particular to a cultivation method for improving the survival rate of windbreak and sand-fixing forest seedlings. Background Art

[0002] Land desertification is a serious ecological problem. Its formation is a complex problem involving multiple factors. On the one hand, it is affected by climate change and improper human activities. On the other hand, it is the result of the existing desert sand source under the action of wind, causing quicksand and sandstorms. Land desertification not only gradually reduces the usable land area, but also aggravates environmental deterioration, frequent disasters, causes huge economic losses, and seriously affects the normal production and life of human beings. In order to solve the problem of land desertification, people have adopted various wind-proof and sand-fixing measures. Among them, planting low shrubs or herbaceous plants with tenacious vitality in the desert is a relatively effective way. However, due to the low rainfall and strong wind in the desert, the planted seedlings are either blown away or buried by quicksand, making it difficult to grow and the survival rate is low. It takes multiple plantings to form a shelterbelt. Summary of the invention

[0003] In view of the problems existing in the prior art, the present invention provides a cultivation method for improving the survival rate of windbreak and sand-fixing forest seedlings. The method has strong windbreak and sand-fixing performance and a high survival rate of the forest seedlings.

[0004] To achieve the above object, the present invention provides the following technical solution: a cultivation method for improving the survival rate of windbreak and sand fixation forest seedlings, comprising the following steps:

[0005] 1) Composting: build a fermentation groove to collect domestic garbage, add soil and compound fertilizer, mix well, and then pile up for fermentation. Cover the surface with film for heat preservation. Turn it over and cover it with film after one week. It will be ready for use after fifteen days.

[0006] 2) Planting: Mix the fermented fertilizer with sand that accounts for 1 / 3 of the fertilizer weight, mix well, put it into a planting frame, and plant the tree seedlings. The planting frame is a hollow structure with openings at the upper and lower ends. A wire mesh is set at the lower end, and cardboard is placed on the wire mesh;

[0007] 3) Nursery management: Centrally maintain and manage the planting frames where the tree seedlings are planted, ensure the supply of water and fertilizer, and spray the leaves with 0.3%-0.5% water and fertilizer when the tree seedlings grow new leaves;

[0008] 4) Transplantation: Transplant the planting frame planted with tree seedlings to the desertified land. Before transplanting, dig multiple rows of planting trenches in the desertified land. The depth of the planting trenches is 40-50% of the depth of the planting frame. The multiple rows of planting trenches are parallel to each other and perpendicular to the main wind direction of the planting site.

[0009] 5) Management after transplanting: Water thoroughly once after transplanting and add 0.1-0.3% urea; drip irrigation and fertilizer are used for daily management.

[0010] As a preferred embodiment of the present technical solution, in step 4) transplanting, the height of the tree seedlings in the planting frame is gradually reduced along the direction of the main wind direction.

[0011] As a preferred embodiment of the present technical solution, the row spacing between multiple rows of planting furrows is 4-6 meters, and the column spacing between the tree seedlings in each row of planting furrows is 0.8-1 meter.
