Subtropic evergreen lawn composite prescription, its lawn construction method and application

Abstract

The invention belongs to the field of engineering technique for ecological greening town in subtropical zones. The employed combined lawn strains are Ling zhi tall fescue, hound tall fescue, beck tall fescue, Jiao zhan tall fescue, midnight English grass, De bi perennial ryegrass and common Bermuda grass, sowing seeds according to the proportion of tall fescue strains 50%, English grass strains 20%, perennial ryegrass strains 10% and Bermuda grass 20%, for two working times and even sowing, through scientific caring and management, in areas of normal climate and management such as Nan jing, the lawn yearly green period is above 320 days, the oversummering and overwintering rate is above 95%, the structure is stable, there are little weeds, the lawn is temperature-resistant, cold-resistant and trample-resistant, and the cost of lawn forming and caring is low, suitable for forming lawns in the green place, square and sportsground.

Description

[0001] One, technical field: the present invention belongs to the technical field of urban ecological greening engineering. 2. Background technology [0002] After searching the national patent network ( www.sipo.gov.cn / sipo / default.htm ), after reviewing related literature and a large number of investigations, there is no grass seed mixed planting formula and ratio suitable for planting evergreen lawns in subtropical regions. Mixed sowing formula and corresponding sowing techniques in temperate and tropical areas. Since the subtropical region belongs to the transitional climatic zone, it is hot in summer and cold in winter. At present, there is no turfgrass species at home and abroad that can resist both heat and cold. In subtropical regions, the turfgrass varieties that can be planted in the subtropical region and can be evergreen all year round are currently used. Excellent cool-season turfgrass varieties such as tall fescue (Festuca arundinacea L.), bluegrass (Poa pratens...

AI Technical Summary

Problems solved by technology

[0004] (1). Solve the problem that the existing commonly used turfgrass varieties have a short green period (below September) and cannot be evergreen throughout the year;

[0005] (2). Solve the problem that a single species of Jianping has a single resistance, can not survive summer or winter and is easy to degenerate;

[0006] (3). Solve the problems of using a single species to build a lawn, the grass group structure is simple, the life is short, the weeds are overgrown, and the quality of the lawn is poor
