Embodiment Construction

[0027] The purpose of the present invention is achieved through the following technical solutions:

[0028] The method for water collection, water retention and water replenishment of the present invention comprises the following steps:

[0029] A. Water collection is the collection and preservation of natural precipitation to provide for the growth and development of forest trees. There are two types of water collection. One is to collect natural precipitation in woodland and tree holes by means of land preparation works and water conservation measures; Collect and store natural precipitation from residents’ roofs, courtyards and road slopes, and use it as supplementary irrigation when trees are short of water.

[0030] B、 Site preparation is to dig and plant tree holes and build water collection areas around the trees. The first function is to loosen the soil, improve the soil structure, and provide more suitable micro-environmental conditions for the growth of tree roots...

Abstract

A method for improving an afforestation survival rate by water collecting, water retention and water replenishing comprises the steps of water collecting, soil preparation, water retention and water replenishing. The water collecting method comprises the steps that a soil preparation engineering mode is used for collecting natural rainfall water into forest land and plant pits; the measure of building a flow collecting face, a flow collecting pool, a water cellar and the like is used, in the adequate rainfall reason, the natural rainfall water is collected and reserved, and the natural rainfall water is used for supplemental irrigation when trees are in short of water. The water retention method comprises the step of using mulching films, wheat straw, dinas and the like for covering the plant pits. The water replenishing method comprises the steps that when it is arid and does not rain and when nursery stock is in water shortage, the methods of micro-irrigation, trickle irrigation, infiltrating irrigation under films, root-irrigation through tube inserting, water injection irrigation and the like are used for water replenishing; soil preparation is conducted, fertilizer is applied to the plant pits, plastic films are mulched for catchment and soil conservation, seeding and planting are conducted, a water collecting face and a water reserving cellar are built to collect rainfall water, and water replenishing and irrigation are conducted in the drought period in spring. The final purpose is to improve the afforestation survival rate and the preserving rate, and to improve the volume of forest tree growth. In addition, the important links further comprise suitable tree species choosing, application of the new technology, new method and new materials of afforestation, cultivation management, disease and pest control and the like.

Description

technical field [0001] The invention relates to a water-collection and water-saving method for afforestation without irrigation in arid and semi-arid areas, that is, an afforestation method including a series of technical systems of water collection, water retention and water replenishment. technical background [0002] Afforestation is one of the main measures to improve the ecological environment in view of the fragile ecological environment, sparse vegetation, and serious soil erosion in my country's arid and semi-arid areas. However, due to drought and other reasons, the survival rate and preservation rate after afforestation are often relatively low. To do a good job in the afforestation work in this area, we must strengthen water collection and water saving work, strengthen the construction of water storage projects, and increase the intensity of rainwater resource development and utilization. Water collection, water retention, and water replenishment series technolog...
