Embodiment 1

[0018] 1 site preparation

[0019] Site selection and land preparation for afforestation

[0020] The afforestation land is selected on the E, W, SE, and SW slopes with a slope of less than 35 degrees, but the land with broken terrain and bare land is not suitable for planting.

[0021] Season and method of land preparation: land preparation in the fall of the year before afforestation, use reverse-slope terraces for site preparation on gentle slopes, the size of reverse-slope terraces is 0.8×2×0.4m, and the soil is thawed in the following spring for shrub afforestation; planting holes are arranged according to reverse-slope terraces, and afforestation plants Row spacing is based on the size of the slope, and the horizontal distance between the upper and lower rows of ditch centers is 2m;

[0022] 2 Arrangement of runoff collection and planting points

[0023] For afforestation in arid mountainous areas, the planting points are arranged in the shape of "pin", and the catchme...

[0034] 1 site preparation

[0035] Site selection and land preparation for afforestation

[0036] The afforestation land is selected on the E, W, SE, and SW slopes with a slope of less than 35 degrees, but the land with broken terrain and bare land is not suitable for planting.

[0037] It is advisable to prepare the land in the first year and afforestation in the next year. On gentle slopes, use horizontal ditch land preparation with a depth of 60cm; in areas with broken terrain or large slopes and vegetation coverage of 0.5, it is advisable to use fish scale pits or caves for land preparation, which can protect the original The vegetation is also conducive to improving the survival rate of afforestation, and the horizontal ditch is 0.5×2.5×0.4m.

[0038] Season and method of soil preparation: land preparation in the autumn of the year before afforestation, and the soil is thawed in the spring of the following year for shrub afforestation; the planting holes are arranged ac...

Abstract

The invention relates to a method for building drought mountain sabina przewalskii, which comprises the following steps of: ploughing soil by advancing a growing season during afforestation, ploughing the soil by a horizontal ditch, a horizontal step or a counter-slope bench terrace at a gentle slope and carrying out shrub afforestation when the soil is thawed in the spring of the next year; arranging planting points in a shape like the Chinese character pin; afforesting when the soil is thawed by 30-40cm in the early spring, soaking a seedling root by slurry prepared from diammonium phosphate and a water-retaining agent before afforestation and selecting first-class and second-class seedlings which grow in 3 to 4 years and have the seedling height of more than 20cm, healthy and strong development and good root system to afforest; in order to advance the crown closure of a sabina przewalskii forest, carrying out hybridizing configuration on shrub species according to the counter-slope bench terrace or the horizontal ditch and configuring caragana and barberry of the shrub species at the sunny slope; and configuring of caragana microphylla, hippophae rhamnoides and dasiphora davurica the tree species at the semi-sunny slope. By changing the traditional afforestation method adopting the cheap, simple and easy method, the afforestation survival rate of the drought mountain sabina przewalskii is improved, the sustainable construction of the modern forestry is accelerated, forest resources are effectively expanded and the ecological environment is improved.

Description

technical field [0001] The present invention relates to comprehensive technology of arid mountain afforestation, in particular to a comprehensive technical system for expanding forest resources, improving ecological environment, and developing ecological forestry, specifically Background technique [0002] It is imperative to improve the ecological environment through afforestation in arid mountainous areas, but the comprehensive afforestation technology in arid mountainous areas is relatively lagging behind, such as the afforestation method that can be found at present, the afforestation method of embedding seedlings with soil, and the planting method of small pits against the wall Such technical measures are all deformations of traditional afforestation methods. The survival rate of Qilian juniper planted in arid mountainous areas with the above-mentioned technologies is only about 50%, which greatly restricts the improvement process of the ecological environment and the ef...
