Problems solved by technology

[0006] The purpose of the present invention is to provide a zero-maintenance false thrift grass greening lawn planting method for the defects of existing urban greening lawns that have high maintenance requirements, so that the false thrifty grass lawn basically does not need to spend manpower after the lawn is built. Material resources are used for maintenance and management such as pest control, fertilization, irrigation, weeding, pruning, etc., and the basic ecological functions and green landscape effects of the lawn can also be guaranteed under zero maintenance conditions

Embodiment 1

[0022] Open public green lawn: the lawn is established by planting stems in holes.

[0023]1. Lawn bed preparation: Before the soil is plowed, use 2 liters of glyphosate with a mass concentration of 10% per acre, and mix 40 kg of water to evenly spray the weeds on the original soil to kill the weeds to reduce the amount of water in the soil. base of weeds. After 4 days, the weeds began to wither and turn yellow, and then the soil was plowed, and the bed soil was rotated twice with a rotary tiller to loosen the bed soil, and the soil particles were uniform and the diameter was less than 1.0 cm. Apply 50-60 kg / mu of organic fertilizer, manually use a rake to make a shape with a slope of about 1-2%, mainly use surface runoff to drain water, and set up inspection wells in low-lying places for drainage. Irrigate the lawn bed with water one day before the lawn is planted, so that the soil of the lawn bed can maintain a good moisture content.

[0024] 2. Lawn planting: Take the sto...

Embodiment 2

[0027] Greening lawns on both sides of the road: adopt the method of laying turf directly. The bed soil is the subgrade soil during highway construction, and the soil fertility is average.

[0028] 1. Lawn bed preparation: Before the soil is plowed, use 2 liters of glyphosate with a mass concentration of 10% per acre, and mix 40 kg of water to evenly spray the weeds on the original soil to kill the weeds to reduce the amount of water in the soil. base of weeds. After 4 days, the weeds began to wither and turn yellow, and then the soil was plowed, and the bed soil was rotated twice with a rotary tiller to loosen the soil in the bed, and the soil particles were uniform, with a diameter of less than 2.0 cm. , slightly lower ridges on both sides, with a slope of about 5%, to facilitate the rapid discharge of rainwater through the surface runoff of the lawn into the inspection well next to the road. Irrigate the lawn bed with water one day before the turf is planted, so that the ...

Embodiment 3

[0033] Greening lawns in residential quarters: adopt the method of laying turf directly. There are some construction wastes in the green basement of the residential area, and the thickness of the overlying soil is about 40cm.

[0034] 1. Lawn bed preparation: Before the soil is plowed, use 2 liters of glyphosate with a mass concentration of 10% per acre, mixed with 40 kg of water to spray the growing weeds, and plow the soil after 4 days, and roughly level it Then apply 100 kg / mu of organic fertilizer, use a rotary tiller to lightly rotate the soil to mix the organic fertilizer with the 10cm soil particles on the surface, and manually level it with a rake to make a slightly inclined slope towards the road with inspection wells. About 3%. Irrigate the lawn bed with water one day before the turf is planted, so that the soil of the lawn bed can maintain a good moisture content.

[0035] 2. Lawn construction: use the turf that has already formed a turf to be planted directly on ...

Abstract

The invention relates to a method for planting a zero-maintenance centipede grass lawn, and belongs to the urban greening construction field. The method comprises the following steps: selecting a centipede grass lawn plant capable of being suitable for zero maintenance, building the lawn by a seed stem pit planting method or a turf plugging method, weeding and applying fertilizers before building the lawn, draining by the form of direct surface runoff, and controlling a lawn bed slope at 0.5-5%; promoting centipede grass to rapidly form a ground creeping stem covering layer by taking measures of keeping soil moisture, controlling weeds, routine mowing and the like in the process of building the lawn, and forcing out the growth space of the weeds to cause weed harm to not occur basically after building the lawn. The method helps maintain dynamic balance of lawn growth by natural rainfall and nutrient cycle by virtue of excellent properties of the centipede grasses such as extreme strong disease and pest resistance, drought resistance, soil-hungry resistance, creeping growth and the like, and can ensure good ecological functions and greening landscape of the lawn under the zero maintenance condition.

Description

technical field [0001] The invention relates to a method for establishing a zero-maintenance false thrift grass green lawn. The false thrift grass lawn after being planted can adapt to zero-maintenance management and ensure the basic ecological greening function and landscape effect of the lawn. It belongs to the field of urban greening construction. Background technique [0002] Lawn is the main component of urban landscaping. Lawn not only has the same ecological greening function as other landscaping plants, but also provides residents with green leisure activities. Therefore, lawn always occupies more than one-third of the urban green space. area. In recent years, the green area of ​​urban lawns in my country has grown rapidly, and many cities have reached or approached the level of 10 square meters per capita. With the increase of lawn greening area, the maintenance burden of lawn green space is getting heavier, and the contradiction between lawn maintenance managemen...
