Method for utilizing desert trace moisture and sand to plant salix mongolica

Abstract

The invention discloses a method for utilizing desert trace moisture and sand to plant salix mongolica. According to the method, deep holes are dug for cuttage planting, the deep holes are backfilledwith desert sand, and moisture of a humid sand layer under the ground surface is supplied to the salix mongolica. The planting method includes the steps that wickers are soaked, wherein the salix mongolica wickers are shaped for use to form seedlings, and the seedlings are soaked in a water area in bundles so that the wickers can fully absorb water; the deep holes are drilled, wherein holes are drilled by means of a one-man gasoline planting machine; the wickers are inserted into the holes, wherein after the holes are drilled, the soaked wickers are quickly inserted into the holes; the holes are filled with the sand, wherein the holes are filled with the desert sand within 24 hours, and then planting is completed. The method for utilizing desert trace moisture and sand to plant salix mongolica is particularly suitable for places in the Tengger desert region, wherein the sand layers of the places are 2 m thick or thicker, the ground surface dry sand layers are 0-40 cm thick, and the water content of humid sand layers is not lower than 5%; hole digging for planting is simple and convenient, planting is facilitated, the survival rate of the salix mongolica is high, and the desert windproof and sand-proof effects are remarkable.

Description

technical field [0001] The invention belongs to the desert planting technology, and relates to a technology for backfilling desert wind and sand, utilizing trace water in the wet sand layer under the desert surface, and drilling deep hole cutting planting technology, specifically a method for planting Salix salix using desert trace water and wind sand. Background technique [0002] Desertification is an ecological disaster in many countries in the world today, and our country is also one of the countries where desertification is seriously harmful, causing hundreds of billions of yuan in economic losses every year. Windbreak and sand fixation, afforestation is one of the effective ways to control desertification. However, planting trees in desert areas, especially in deserts, is very difficult. Due to the double hazards of drought and wind and sand, it is difficult for trees planted in the desert to survive. [0003] In my country, the desert is expanding at a rate of more t...

AI Technical Summary

Problems solved by technology

[0007] 1. Water resources are scarce, and each tree needs to be watered many times to survive, so it will cause serious waste of water resources and is unrealistic

[0008] 2. Due to the thick layer of dry sand in the desert and the state of quicksand, the quicksand will be backfilled when traditionally digging a hole with a shovel, so it is difficult to dig a deep hole when planting trees. If you want to dig a one-meter-deep hole, the hole will be very large , time-consuming and labor-intensive, and artificial backfilling of sandy soil will cause the phenomenon that the bottom cavity is not filled properly; if the tree pit is dug shallow, the efficiency of tree pit digging will be improved, but the survival rate of trees will be significantly reduced, so that the bottom of the pit cannot reach the wet soil layer , which causes the roots of the saplings to be in the dry sand layer, and the poured water will seep quickly and be competed by the surrounding dry sand, eventually causing the saplings to die

[0009] 3. The foundation of the shallow-planted saplings is unstable, and it is difficult to resist the wind and sand in the desert and be blown down or uprooted. At present, there is no known method for the above-mentioned problems that can be properly solved at the same time
