Problems solved by technology

However, the main technical difficulty in cross-seeding of cold-season and warm-season grasses lies in the fact that the two types of grasses have different growth habits and competitive abilities. , one type of grass will eliminate another type of grass, so that the compound turf community after overseeding will succeed to the uneven single turf community

Embodiment 1

[0034] The method for overseeding the cool-season grass and the warm-season grass provided by the present embodiment to build a compound turf comprises the following steps:

[0035] (1) In May, sow Zoysia grass seed on the soil of the football field lawn site to be sown, the seeding rate is 12g / m 2 .

[0036] (2) Around mid-September, trim the warm-season grass growing on the lawn site to a height of 1 cm, and then use a grass groomer to groom the warm-season grass on both sides , the second weeding direction is perpendicular to the first weeding direction; then sow the cool-season grass Poa annua at a seeding rate of 20g / m 2 . Other measures can be handled by conventional methods.

Embodiment 2

[0038] The method for overseeding the cool-season grass and the warm-season grass provided by the present embodiment to build a compound turf comprises the following steps:

[0039] (1) In May, sow Zoysia grass seed on the soil of the football field lawn site to be sown, the seeding rate is 15g / m 2 .

[0040] (2) Around the end of September, trim the warm-season grass growing on the lawn site to a height of 1 cm, and then use a grass groomer to groom the warm-season grass on both sides , the second weeding direction is perpendicular to the first weeding direction; then sow the cool-season sedge grass with a seeding rate of 25g / m 2 .

Embodiment 3

[0042] The method for overseeding the cool-season grass and the warm-season grass provided by the present embodiment to build a compound turf comprises the following steps:

[0043] (1) In June, sow Zoysia grass seed on the soil of the football field lawn site to be sown, and the seeding rate is 10g / m 2 .

[0044] (2) Around the beginning of October, trim the warm-season grass growing on the lawn field to a height of 1 cm, and then use a grass groomer to groom the warm-season grass on both sides. The second weeding direction is perpendicular to the first weeding direction; then sow the mixed seeds of cool-season sedge grass species and red fescue species, and the sowing rate of the mixed seeds is 20g / m 2 , the weight ratio of the seeds of Carex and Red Fescue in the mixed seeds was 0.6:0.4.

Abstract

The invention discloses a method for establishing and planting a composite lawn through overseeding of cool season turfgrass and warm season turfgrass and the composite lawn, and relates to the technical field of football field lawn establishing and planting. The method includes the following steps that warm season turfgrass seeds are sowed at a to-be-sowed lawn, and after the warm season turfgrass is budded and before the dormant period, and the cool season turfgrass seeds are sowed, wherein the warm season turfgrass is zoysia japonica, and the cool season turfgrass is one of bluegrass, red fescue and carex stenophylloides or a composition of bluegrass, red fescue and carex stenophylloides. According to the method, the suitable cool-season-turfgrass-seed one of the bluegrass, the red fescue and the carex stenophylloides or the composition of the bluegrass, the red fescue and the carex stenophylloides is selected and is subjected to overseeding with warm-season-turfgrass zoysia japonica, the two seeds are separately sowed, namely, the two seeds are sowed at different time periods, and therefore the formed composite lawn has the long green period and good uniformity.

Description

technical field [0001] The invention relates to the technical field of turf establishment and planting in football fields, in particular to a method for establishing a composite turf by overseeding cool-season grass and warm-season grass and the composite turf. Background technique [0002] Existing football field turf is mainly a single type of grass species, cool-season grass or warm-season grass. One of the main problems faced by this single type of football field lawn is that the warm-season grass has a long withering and yellowing period due to the low temperature in winter, resulting in a short green period and cannot be suitable for playing in winter; The many diseases and pests caused by it cannot be suitable for competitions in summer. From the perspective of a single turfgrass of warm-season grass or cool-season grass, it is still difficult to adopt a certain grass species that can keep the lawn evergreen all year round and have good disease resistance.
