Afforestation method of platycladus orientalis in green rocky hill

Abstract

The invention discloses an afforestation method of platycladus orientalis in a green rocky hill. The method specifically comprises the following steps that S1, firstly, seedling planting pre-treatment is carried out, wherein local high-quality strong seedlings for more than two years are adopted, during lifting of the seedlings, damage roots such as broken roots and peeled roots which have large wound surfaces and are not easy to heal can occur, the roots must be pruned, a shear mouth should be smooth during pruning, and at the same time, overlong main roots are subjected to short pruning. The provided afforestation method of the platycladus orientalis in the green rocky hill has the advantages that the survival rate of the platycladus orientalis in the green rocky hill can be greatly increased, the vegetation coverage is increased, the water and soil loss is reduced, and for limestone mountain regions with lean soil and less water, a soil water-retaining agent is utilized to effectively enhance the water-retaining property of soil, reduce the loss of soil nutrients, increase the utilization rate of water, be conductive to quickening the vegetation restoration process of the green rocky hill, promote the sustainable development and ecological protection of regional natural resources and lay a foundation for realizing the ambitious goal of clear water and green hills as soon as possible.

Description

technical field [0001] The invention relates to the technical field of afforestation, in particular to a method for afforestation of oriental cypress in Qingshi mountainous area. Background technique [0002] Since the 1970s, through the active research of many experts at home and abroad, the application of water-retaining agents in the fields of soil structure improvement, agricultural water retention and drought resistance, seed soaking, afforestation, and fresh flowers, vegetables, and fruits has made important progress. Water-retaining agent is a general term for high-molecular materials with high water-absorbing characteristics, also known as soil water-retaining agent, humectant, super-absorbent resin, and polymer water-absorbing agent. Absorb hundreds to thousands of times its own weight in deionized water. Most water-retaining agents swell into hydrogels after absorbing water, and then slowly release water for tree roots to absorb and utilize, thereby enhancing soil...

Problems solved by technology

Due to the lack of water, the survival rate of afforestation in these areas is very low. Therefore, how to work hard on water conservation and improve the survival rate of afforestation on barren hills has become a difficult problem to be solved urgently in afforestation on barren hills
