Cultivation method for lawns of sloping field type coastal heavy saline-alkali land

Abstract

The invention provides a cultivation method for lawns of a sloping field type coastal heavy saline-alkali land. The cultivation method comprises the following steps of laying a salt discharge system, laying an irrigation system, carrying out raw soil preparation, planting festuca arundinacea, planting zoysia matrella, planting perennial ryegrass and carrying out planting post-management. The step of laying the salt discharge system comprises the following steps: digging salt discharge ditches properly along the altitude direction of a sloping field from the top of the sloping field to the base part of the sloping field, wherein the salt discharge ditches are 1m to 1.2m in depth; and laying salt discharge underground pipes in the ditches according to a principle that one pipe is arranged in one ditch. The step of laying the irrigation system comprises the following steps: laying the irrigation system at a position which is 75cm to 80cm in depth below the ground surface, wherein the laying space of irrigation water pipes is 5m; setting up one water spraying pipe every other 5m on each water pipe, wherein each water spraying pipe can extend to be a part which is 15cm to 20cm above the ground surface and a spraying nozzle capable of realizing 360-degree water spraying is mounted at a pipe opening of each water spraying pipe. The cultivation method for the lawns of the saline-alkali land, provided by the invention, has the advantages of rapid lawn formation speed, high lawn survival rate and uneasiness of degradation.

Description

technical field

[0001] The invention relates to a lawn cultivation method on saline-alkali land, in particular to a lawn cultivation method on slope-type coastal heavy saline-alkali land. Background technique

[0002] As we all know, for the greening of saline-alkali land, the method of soil replacement and greening commonly used at present has caused great damage to the existing cultivated land and ecological environment.

[0003] The "original landscaping" technology, which is low in cost and conforms to the development principles of sustainable landscaping, has gradually been paid attention to by people. If the original soil greening is carried out, it will be of great benefit to the sustainable development of the ecological environment, but the original soil greening of saline-alkali land is extremely difficult.

[0004] Lawn, as an indispensable vegetation type in the green space ecosystem, not only has the functions of greening and beautifying the soil environment, bu...
