Embodiment Construction

[0034] Below in conjunction with embodiment describe in detail:

[0035] 1. In step ①

[0036] The soil finishing requires that the soil plowing depth is 25-35cm, and after plowing, it shall be promptly raked, crushed and pressed with a compactor, and the continuous operation of raking, plowing and compacting shall be implemented.

[0037] 2. In step ②

[0038] The construction of the drainage canal requires that the branch and main canals are connected and connected with the farmland drainage system, and the width of the flat bed is between 15-18m.

[0039] 3. In step ⑦

[0040] Described planting technology requires nitrogen fertilizer to select urea, ammonium bicarbonate, ammonium nitrate or ammonium sulfate, and its consumption is 4-6g / m 2 ;

[0041] Phosphate fertilizer is calcium superphosphate, its dosage is 8-12g / m 2 ;

[0042] Potassium fertilizer is potassium sulfate or potassium nitrate, the dosage is 8-12g / m 2 ;

[0043] And with the application of trace el...

Abstract

The invention discloses a method for planting lawn in saline-alkali soil and relates to the fields of the saline-alkali soil control and planting technology. The method comprises the steps of: 1, soil arrangement; 2, establishment of a drainage canal; 3, straw application; 4, sand covering on a surface; 5, selection of grass seeds; 6, planting technology; 7, fertilizer application according to formulas; and 8, cultivation management. In the method, the bare surface of the saline-alkali soil can be covered effectively in short time, the water evaporation of the ground is reduced, and the saltness of the surface soil is reduced; the saline-alkali soil can be utilized comprehensively in a large area, and the vegetation structure of the saline-alkali soil can be adjusted; and the vegetation cover area of the saline-alkali soil is enlarged, and the ecological environment is protected and improved.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land treatment and planting, in particular to a lawn planting method on saline-alkali land. Background technique [0002] Saline-alkali land is an important land resource for agricultural development and utilization. my country has about 36.3 million hectares of saline-alkali land, about 75% of which have not been effectively controlled and rationally developed and utilized. Saline-alkali soil contains excessive salt, toxic substances, high alkalinity, and poor soil properties, which inhibit the growth of plants, making it difficult for plants to grow on saline-alkali soil, forming a large area of ​​saline-alkali wasteland, and the ecological environment is poor. 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. [0003] Lawn,...
