Construction method for sandy land vegetation recovery

Abstract

The invention discloses a construction method for vegetation recovery on sandy land. The method is to firstly make the straw into a straw rope, soak it in the garbage bacterial seed solution, and then mix the straw powder, manure, spirulina, porous layered silicate sand control new material, and plant seeds successively to obtain a plant containing Straw mix for seeds. During construction, a series of ditches are first opened on the sandy land, and spare straw ropes are placed in the ditch, then the straw mixture containing plant seeds is sprinkled in the ditch, and then watered and covered with soil. The method can fix water, fix fertilizer and increase fertilizer in sandy land, improve soil fertility, and can provide good supporting conditions for germination of plant seeds and later growth of plants.

Description

Technical field [0001] The invention relates to a method for planting plants suitable for sandy desertification land, so as to facilitate the vegetation restoration of the desertification land. Background technique [0002] According to people's experience of fighting against soil desertification for many years, although there is no less fertilization and less watering when planting turf or trees and after planting, due to the poor water and fertilizer retention of the soil quality, the seedlings will not get enough water. Without the guarantee of sufficient fertilizer, and without the support of local soil water retention and water release functions, often the seedlings seem to be good in the first year, but generally die young after two or three years. At present, for the planting of plants in sandy and desertified land, water-absorbing and water-fixing agents are generally used to improve the water-deficient soil environment, such as Ge Xuegui et al. , 2001, 12) adopt SA...

Problems solved by technology

[0002] According to people's experience in fighting against soil desertification for many years, although there is no less fertilization and less watering when planting turf or forest trees and after planting, due to poor water and fertilizer retention properties of the soil, the seedlings will not get enough water. The fertilizer is guaranteed, and the water retention and water release function of the local soil is not supported. Often the seedlings seem to be good in the first year, but they generally die after two or three years.

At present, for planting plants in sandy and desertified land, water-absorbing and water-fixing agents are generally used to improve the water-deficient soil environment, such as Ge Xuegui et al. , 2001, 12) adopt SAP (Super absorben polgmer) superabsorbent resin, pillared montmorillonite, aluminum-deficient type zeolite; CN1343754 adopts bentonite and zeolite; Yet these materials can only temporarily improve the water shortage situation, and some will also Secondary pollution to the environment

In addition, CN1078343 passes the straw through the paper pulp, adds nutrient solution, and finally makes a paper tape, sows the seeds between the two layers of paper tape, and directly spreads the paper tape in the soil when sowing: CN1509598 uses straw and agricultural product processing waste, etc. Pressed into a plant board containing the nutrients needed for plant growth, which can be used for seed germination of lawns, etc.; although these technologies solve the problems of no-tillage and seed germination, they ignore the transformation and fertilization of the soil environment, which is not conducive to the planting of plants continue to survive and grow for a long time
