Embodiment 1

[0018] The activated sludge is air-dried and crushed into the size of rice grains, and 10.7 kg of the activated sludge powder, 88 kg of phosphogypsum, 0.1 kg of gum arabic powder, 0.1 kg of pulp, 0.1 kg of water-retaining agent, and 1 kg of sulfur powder are mixed evenly to make 100 kg As a growth substrate, 10 kilograms of ryegrass seeds are uniformly mixed with the growth substrate to prepare a sowing material; the prepared sowing material is evenly spread on the waste ground to ensure that the thickness of the thinnest part is ≥ 1 cm, and then the cultivation management is carried out according to a conventional method.

Embodiment 2

[0020] The specific method is the same as in Example 1; wherein, 30 kg of activated sludge powder, 68.7 kg of phosphogypsum, 0.1 kg of gum arabic powder, 0.1 kg of paper pulp, 0.1 kg of water retaining agent, 1 kg of sulfur powder, and 10 kg of ryegrass seeds.

Embodiment 3

[0022] The specific method is the same as in Example 1; wherein, 15.7 kg of activated sludge powder, 83 kg of phosphogypsum, 0.1 kg of gum arabic powder, 0.1 kg of paper pulp, 0.1 kg of water retaining agent, 1 kg of sulfur powder, and 10 kg of ryegrass seeds.

Abstract

The invention discloses a method for recovering plant cover in situ at the abandoned land belonging to plant cultivation methods; and is object to provide a method for planting grass in situ at the abandoned land without soil. Its technical scheme includes: mixing uniformly the grass seeds and the growth substrate at a weight ratio of 1:10 to confect a sowing material, uniformly covering the sowing material on the surface of the abandoned land, and then performing breeding management according to the conventional method, wherein, the growth substrate is confected by the following material at weight percentage: 68.3-88% of phosphogypsum powder, 10.5-0% of activated sludge powder, 0.1% of Acacia powder, 0.1% of paper pulp, 0.1-0. 5% of water-loss reducer and 1% of sulfur powder. The grass planted by the method has high survival rate, fast plant cover growth and good water retaining and earth solidifying effect; can not only prevent soil erosion, but also significantly improve the ecological environment and natural landscape; has small engineering amount, convenient construction, low investment and the like advantages; and the method is an ideal method for abandoned land reclamation treating and plant recovering.

Description

Technical field: [0001] The invention relates to a method for planting turf, in particular to a method for planting turf in situ on an abandoned land to form vegetation. Background technique: [0002] As we all know, although our country has a vast area, the phenomenon of land desertification and rocky desertification is relatively serious. In recent years, with the rapid development of infrastructure, a large number of abandoned lands have been formed, further exacerbating the deterioration of the ecological environment. Abandoned land is a broad and relative concept. The abandoned land mentioned in this article mainly refers to various waste rock dumps, bare wasteland, and various sites where natural vegetation has been destroyed after manual excavation. It also specifically refers to karst areas that are difficult to grow. Vegetated desert, stony desert. Because the abandoned land is mostly barren soil or broken rock, the site conditions, water and fertilizer conditions...
