Method for updating deteriorated grassland bluegrass lawn at low cost in north

Abstract

The invention provides a method for updating a deteriorated grassland bluegrass lawn at low cost in the north. Weed control, pruning height control, lawn partition area and turf block size determination, rooting hastening with grass blocks soaked in pesticide, determination of the number of turf blocks planted in a community per square meter and planting positions, compacting, watering, sand covering, growth regulator application and other technologies are applied, on the basis of the natural rules of plant interspecific competition and the survival of the fittest, zoysia japonica can easily invade the deteriorated grassland bluegrass lawn due to strong creeping stems and the strong growing vigor and competitiveness, other grass seeds can hardly invade the lawn once the population of the zoysia japonica is formed, and therefore the aim of updating the deteriorated grassland bluegrass lawn at low cost is achieved. The effective method can be applied to the production practice of landscaping in a large area, can solve the problem of a deteriorated cool-season lawn, and can lower updating cost.

Description

technical field [0001] The invention relates to a technology for regenerating bluegrass turf in degraded grassland, in particular to a low-cost method for renewing degraded bluegrass grassland in degraded cool-season grassland Zoysia sativa through artificial assistance to promote natural succession. Background technique [0002] As one of the garden landscapes, the lawn green space can provide people with more green spaces for rest and activities, and realizes people's good wish to return to nature. In northern China, especially in Beijing, Tianjin, Shenyang, Dalian and other regions, due to the climate restrictions of cold and dry winter and hot and dry summer, most of the lawns in the lawn green space of garden projects are cool-season grass species.
