Embodiment Construction

[0032] Specific embodiments of the present invention will be described in detail below.

[0033] A drought-resistant afforestation method for poplars in a semi-arid area, comprising the steps of:

[0034] 1. Land preparation

[0035] Site preparation can improve site conditions such as microclimate, soil moisture, soil nutrients, and soil aeration. When poplar afforestation can be used comprehensive land preparation and partial land preparation. When the economic conditions are good, the soil should be fully plowed in autumn and winter, with a plowing depth of 30cm to 40cm. Before afforestation in the next spring, the ground should be raked and then a planting pit should be dug. The length, width and depth of the pit should be 80cm×80cm×(80cm~ 100cm). If the economic conditions are not good enough, you can directly dig a planting pit with the same specifications as above.

[0036] 2. Raising seedlings and transporting seedlings

[0037] The quality of poplar seedlings is ...

Abstract

The invention discloses a semi-arid region aspen anti-drought afforestation method. The method includes the following steps of firstly, preparing a land, wherein soil is turned over comprehensively inautumn and winter by the depth of 30-40 cm, planting pits with the length, width and depth being 80 cm*80 cm*(80-100) cm are dug after the land is raked flat before afforestation in spring of the second year, and the planting spacing of aspen is 2 m*2 m or 2 m*3 m; secondly, lifting seedlings and conveying the seedlings, wherein the seedlings are adjusted nearby, the seedlings are planted instantly after being lifted or planted in the current day; thirdly, conducting transplanting; fourthly, conducting management, wherein after the seedlings are planted, the young forest tending and protecting are reinforced, and the timely intertilling and weeding, fertilizer applying and irrigating, disease and insect pest preventing, forest fire disaster preventing and artificial damage preventing areconducted. The method is high in practicability, low in manufacturing cost and suitable for semi-arid region aspen afforestation and can effectively improve the water utilization efficiency and remarkably improve the afforestation survival rate.

Description

technical field [0001] The invention relates to the technical field of forest cultivation, in particular to a new method for drought-resistant afforestation of poplars in semi-arid areas. Background technique [0002] Poplar is widely distributed and grows rapidly. It is a good timber forest and ecological protection forest tree species. For a long time, poplar has played a very important role in the semi-arid area as the main tree species of the Three-North Shelterbelt and the tree species of industrial raw materials. However, in production practice, the survival rate of poplar afforestation is often low due to drought and water shortage. In order to improve the survival rate of poplar afforestation, effectively solve the problems of industrial timber production and improve the ecological environment, there is an urgent need for a poplar afforestation technology that is suitable for semi-arid areas and can effectively improve the survival rate. [0003] The present invent...
