Embodiment 1

[0033] Production method of hybrid Bermuda pure turf:

[0034] The turf production base is the original rice-planting farmland. After 2 repeated operations of rotary tillage, scraping and rolling, the firmness of the lawn bed soil has reached 87%, and the flatness error has been controlled to about 8mm. Open ditches and release water for irrigation for 24 hours. After the lawn bed has completely absorbed the water, drain the accumulated water on the surface.

[0035] Cut the stolons of hybrid Bermuda (species TIFDWARF) into 3-5 cm long grass stems, and spread them manually on the lawn bed soil that has been compacted and leveled and absorbs enough water. The amount of grass stems per square meter is about 0.5 kg, and the grass stems were spread as evenly as possible. Immediately after planting the grass stems, use a roller to press the grass stems into the soil on the surface of the lawn bed.

[0036]Immediately after planting the grass stems, ditch the ditch and release wat...

Embodiment 2

[0041] The production method of pure turf of false thrift grass:

[0042] Select the farmland where rice was originally planted, and through repeated operations of rotary tillage, scraping and rolling twice, the firmness of the bed soil has reached 90%, and the flatness error has been controlled to about 8mm. Open ditches and release water for irrigation for 24 hours. After the lawn bed has completely absorbed the water, drain the accumulated water on the surface.

[0043] Cut the stolons of False Thrift Grass (the variety is commoner) into 5-10cm long grass stems, each grass stem has more than 3 buds; manually plant the grass stems into the lawn bed soil that has absorbed enough water, and the grass stems More than 50% of the stems are buried in the soil, and the part exposed to the ground contains at least one bud; the distance between planting holes is controlled at 15-20cm.

[0044] After the grass stems are planted, immediately ditch the water to keep the lawn bed soil m...

Embodiment 3

[0048] Production method of bluegrass pure grass turf:

[0049] Choose a relatively flat farmland, irrigate until the soil moisture content is in the range of 15-20%, and repeat the operations of rotary tillage, scraping and rolling twice, and the firmness of the bed soil will reach 85%, and the flatness error will be controlled to about 8mm . Ditch the water for 24 hours. After the lawn bed has completely absorbed the water, drain the accumulated water on the surface.

[0050] Use a seeder to evenly sow the seeds of bluegrass bluegrass on the flat bed soil that has been compacted and leveled and absorbs enough water. The amount of seeds per square meter is 20 grams. Immediately after sowing, use a road roller to press the seeds into the lawn bed in the surface soil.

[0051] Immediately after the sowing is completed, ditch the water and irrigate immediately to keep the bed soil moist, and the thickness of the surface water is controlled at about 2mm. After planting for 20 d...

Abstract

The invention relates to a production method for pure turf without culture substrate. Soil after being rolled and compacted is used, and gaps between soil particles are eliminated, so that the root system of the turf cannot prick into the soil and can only adhere to the surface layer of the compacted soil to grow, enough water and wettability degree can be kept, and enough medium-weight and micro-element nutrition particles can be provided for the growth of the turf by irrigating the compacted soil. In the production management, the high-quality turf still can be produced quickly only by providing enough macro-element nutrients like nitrogen, phosphorous and potassium. The firm turf layer is formed by staggered growth of stolon, root stock and the root system, the forming turf only adheres to the surface of the compacted soil to grow instead of pricking into the soil to grow, the turf can be cut into different sizes as needed, the turf can be torn down from the soil manually, and the turf can be rolled to a turf roll or be folded into a turf block to be sold.

Description

technical field [0001] The invention relates to a technique in the field of plant planting, in particular to a method for producing pure turf without a cultivation substrate. Background technique [0002] Turf is a transplanted commodity used for lawn planting, which refers to pieces of lawn that are shoveled out and sold. The turf is composed of the stems and leaves of the lawn plants above the ground and the root system of the underground part and the accompanying soil or matrix. The turf can be directly planted on the ground to form a lawn in greening construction, which has the advantages of fast lawn formation and simple construction. The direct planting method requires a large amount of turf to build a lawn, and the required turf area is almost equal to the area of ​​the completed lawn. However, the working hours of general greening projects in my country are very tight, and basically all need to be achieved in a short period of time. Therefore, most of the greening l...
