Method for interplanting ryegrass in Cynodon dactylon in central China

Abstract

The invention discloses a method for interplanting ryegrass in Cynodon dactylon in central China. The method comprises the following steps: treatment of two grasses in the interplanting process of ryegrass, and growth process control of the ryegrass in a translating period after the reviving and growth the next year. The method is used to make the ryegrass have good growth advantages and rapidly form a strong and beautiful lawn and avoid the dry yellow phenomenon of the lawn, can promote the reviving and growth of the ryegrass and inhibit the growth of the ryegrass in order to accelerate the translating of the interplanted ryegrass lawn, and protects the growth of original ryegrass, so the method is suitable for the central China to make the values of the lawn reach the optimum level.

Description

technical field [0001] The invention belongs to the technical field of landscaping, and in particular relates to a method for inter-sowing grasses, in particular to a method for inter-sowing ryegrass on Bermuda lawns in central China. Background technique [0002] Lawns have the functions of purifying air, absorbing dust, preventing noise, taking drugs, reducing soil erosion, improving soil structure, beautifying cities, and improving urban ecology. [0003] The climate in central China is characterized by high temperature in summer and low temperature in winter. In terms of turfgrass selection, it can be divided into cool-season grasses and warm-season grasses. Both have deficiencies, such as cool-season grasses with long green periods. However, it is difficult to maintain and manage in summer, and has poor heat and drought resistance. Warm-season grasses have strong heat and disease resistance in summer, but they stop growing and go dormant in autumn, winter and spring und...

Problems solved by technology

[0003] The climate in central China is characterized by high temperature in summer and low temperature in winter. In terms of turfgrass selection, it can be divided into cool-season grasses and warm-season grasses. Both have deficiencies, such as cool-season grasses with long green periods. However, it is difficult to maintain and manage in summer, and has poor heat and drought resistance. Warm-season grasses have strong heat and disease resistance in summer, but they stop growing and go dormant in autumn, winter and spring under cold weather conditions, and the grass color is withered and yellow.

[0007] The warm-season grasses that are widely planted in central China are not suitable for interplanting cool-season grasses. There are two main reasons: First, although Manila lawns wither and dormant in winter, their ecological habits of being sunny and not tolerant to shade have not changed. The next year’s rejuvenation accumulates nutrients and energy, and the cool-season turf that grows vigorously in winter just deprives it of this ecological habit. The cool-season turf plants block the sunlight intake of the Manila turf, which directly leads to the growth of the Manila turf when it turns green in the next year. Bad, even mass death

Secondly, the grass layer of Manila lawn is dense, especially the lawn that has grown for many years. Many grass seeds cannot reach the soil layer, but stay in the Manila grass layer, coupled with the environmental characteristics of rainwater and poor air permeability of the dense grass layer, which leads to grass seed rot, which seriously affects the germination of cold-season grass seeds inter-sowed Rate
