Problems solved by technology

At first, this kind of overseeding update only played a temporary filling role. When the spring temperature rises and is conducive to the growth of Zoysia grass, the overseeding grass seeds will gradually disappear. However, the overseeded cool-season grass species are all newly sown and have tenacious vitality. Conventional management methods cannot completely subside in the whole spring or even early summer of the following year, so that Zoysia turfgrass can grow in the normal growing season (late spring to late autumn). ) can not grow normally, and the coverage rate and lawn properties become worse, which seriously affects the ornamental value of Zoysia turf lawns in these two areas.

Embodiment 1

[0020] Experiment site: Zoysia lawn of Jiangsu Agriculture and Forestry Vocational and Technical College

[0021] 1) Sowing: Oversow perennial ryegrass on Qingdao Zoysia lawn in autumn, with a seeding rate of 1.5g / m 2 , carry out routine management (with comparative example 1);

[0022] 2) Water control management: After winter, from the beginning of February to the end of February of the following year, control irrigation in addition to natural precipitation. If there is no natural precipitation, water once a month. The soil is 5cm deep and moist. Natural precipitation eliminates the need for artificial watering, and the natural precipitation needs to accumulate to reach a depth of 5cm in the soil to moisten;

[0023] 3) Pruning management: After winter, from the beginning of December to the end of February of the following year, the cool-season turfgrass is trimmed twice a month, with an interval of about 15 days between each trimming. Follow the 1 / 3 pruning principle, for...

Abstract

The invention discloses a method for promoting fading of overseeding cold-season turf grass in springs. The method includes 1) seed sowing, 2) water control management, 3) pruning management, 4) growth inhibitor treatment and 5) mulching treatment. The method has the advantages that thorough fading of the overseeding cold-season turf grass can be promoted by the aid of the method in early springs,accordingly, warm-season zoysia japonica can completely assuredly timely revive and healthfully grow, landscape effects of the warm-season zoysia japonica turf grass in regular growing seasons (fromlate springs to late autumns) can be effectively improved, and the service life of warm-season turf can be prolonged.

Description

technical field [0001] The invention belongs to the planting field of plants of the genus Zoysia, and in particular relates to a method for promoting the fading of overseeded cool-season turfgrass in spring. Background technique [0002] Overseeding is a commonly used method in warm temperate and warm tropical regions of my country to ensure that lawns are evergreen throughout the year. The Zoysia turfgrass planted in these two areas is dormant due to the cold, which makes the turfgrass grow slowly or turn brown or withered yellow, which makes the lawn landscape fade. The period of greening in early summer of the second year forms an intermittent period of lawn utilization. In order to keep the winter green, the method of overseeding can be used to keep the lawn evergreen in winter. Overseeding is the additional sowing of cold-type turfgrass on a Zoysia lawn. At first, this kind of overseeding update only played a temporary filling role. When the spring temperature rises a...
