Embodiment Construction

[0027] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples serve to illustrate the present invention, but do not limit the scope of the present invention.

[0028] In the method for prolonging the green period of turfgrass according to the invention, the lawn is covered and protected with a cover in winter, and the cover is made of non-woven fabric.

[0029] Such as figure 1 As shown, one embodiment of this method is applied to prolonging the green period of turfgrass in northern China, and specifically includes the steps:

[0030] S1: In mid-to-late November, trim the lawn grass to the predetermined stubble height, apply slow-release fertilizer, pour frozen water thoroughly, then cover with double layers of non-woven fabric, and fix it around;

[0031] S2: After covering, choose sunny and windless weather, uncover the non-woven fabric ever...

Abstract

The invention discloses a method for prolonging a green period of a lawn. In winter, a covering object is used for protecting the lawn in a covering way, the covering object adopts non-woven fabrics which can increase the temperature of soil, and maintain the stable changing temperature difference between day and night, thus having important significance on promoting root system growth and preventing influence of freeze injury. The non-woven fabrics can increase the soil moisture content, so that the cases that grass in the lawn becomes withered and yellow and even dies due to droughty and water shortage in dry and blowy winter can be avoided. The non-woven fabrics have large fiber gaps and good air permeability, can avoid the freeze injury to the lawn caused by droplets generated by the changing temperature difference between day and night. Besides the non-woven fabrics have poor light transmission, which can reduce the light intensity and avoid the strong light exposure of the lawn in winter. Compared with the lawn without using any covering object, the lawn covered by non-woven fabrics in winter cannot be yellow in winter, when the covering object is uncovered in March next year, the lawn viewing quality can be achieved the using standards after about one week.

Description

technical field [0001] The invention relates to the maintenance of lawn grass, in particular to a method for prolonging the green period of lawn grass. Background technique [0002] The temperature in northern my country is low in winter, and the wind and sand are generally large. If the lawn is not covered with mulch in winter, the turfgrass will easily turn yellow due to low temperature, water shortage and drought in winter, and will not turn green or even die in the next spring. At present, the commonly used materials for covering mainly include straw curtains, non-woven fabrics, plastic films, sunshade nets, quilts, etc. Different covering materials have different effects. Straw curtains tend to carry the same pathogenic bacteria as lawns, causing lawn diseases, and their firmness is poor. The plastic film has poor air permeability, and the water droplets produced by temperature changes are likely to cause freezing damage to the tips of turfgrass and turn yellow. Quilt...
