Saline-alkali land lawn planting method

Abstract

The invention discloses a saline-alkali land lawn planting method which comprises the following steps: S1, land leveling: leveling the land to a preset reference elevation; S2, uniform arrangement of salt discharge wells: burying concealed pipes, and dissolving and discharging salt on the surface layer of soil in combination with irrigation and drip washing; S3, application of peat soil and gypsum: applying the peat soil and the gypsum into the soil through a ploughing machine, and performing ploughing and uniform stirring; S4, laying of fine sand; S5, selection of proper grass seeds for sowing; S6, watering and ventilating: carrying out regular spraying and watering to keep the soil moist, and uniformly punching air holes through a conical tool; S7, regular fertilization: scattering organic fertilizer and calcium superphosphate through a fertilizer throwing machine; and S8, reduction of water evaporation: supplying sufficient nutrition to the lawn, reducing water evaporation, and applying rooting powder and an anti-transpiration agent to the soil. According to the saline-alkali land lawn planting method, the saline-alkali land can effectively cover the lawn, the greening area is increased, the salt content of the saline-alkali land is increased, and the ecological environment is protected and improved.

Description

technical field [0001] The invention belongs to the field of lawn planting, and in particular relates to a lawn planting method on saline-alkali land. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which my country is the largest 99.13 million hectares. The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. However, as the available land resources are decreasing day by day, saline-alkali land is a precious land resource, and its development, utilization and improvement will become an important source of available land. The new urban areas of...

Problems solved by technology

Lawn, as an indispensable vegetation type in the green space ecosystem, not only has the function of greening and beautifying the saline-alkali soil environment, but the existing method of planting lawn in saline-alkali land has a low survival rate, is easy to die, and consumes more water.
