Problems solved by technology

[0005] 1) There is an obvious interval between the replacement of old and new lawns. During the reconstruction period, the lawn has lost all ecological functions, and the soil is exposed, which is easy to cause soil erosion;
[0006] 2) high cost
Lawn rebuilding costs not only the cost of a new lawn, but also the cost of completely removing the old lawn, which is more than the cost of a new lawn

Embodiment 1

[0029] 1. In spring, after the temperature stabilizes above 18°C, use a weed groomer to weed the seaside paspalum lawn that has turned green. The depth of weeding is 30mm, and the thinned grass stems are collected as seashore paspalum seed stems (each section Grass stems contain at least 1 stem node) for later use.

[0030] 2. On April 21, perform a low pruning on the bluegrass lawn that has formed a lawn, the pruning height is 20mm, and the lawn height after low pruning is kept at 20mm;

[0031] 3. After low pruning, drill holes on the bluegrass lawn with a depth of 80mm and a hole spacing of 5cm;

[0032] 4. Vertically insert a section of seashore paspalum seed stem section containing 3-4 internodes in the hole;

[0033] 5. Cover the seashore paspalum stems with soil. The thickness of the covering soil is controlled at about 8mm, so that at least one node of the seashore paspalum stems is exposed to the ground, and the soil is firmly stepped on so that the seed stems buried...

Embodiment 2

[0037] 1. In spring, after the temperature stabilizes above 18°C, use a turf machine to lift out all seashore paspalum lawns, wash off the soil on the lawn, and cut the lawn into 20-150mm long stems (each grass stem contains 1 —4 stem nodes), as a seed stem for subsequent use.

[0038] 2. On May 10, 3 times of low pruning was carried out on the tall fescue lawn that had already been pruned, the pruning height was 30mm, and the lawn height after low pruning was kept at 30mm;

[0039] 3. After the tall fescue lawn is properly trimmed, then drill holes on the tall fescue lawn. The depth of the holes is 30-80mm, and the hole spacing is about 5-6cm;

[0040] 4. Vertically insert a section of seashore paspalum seed stem section containing 1-4 internodes in the hole;

[0041] 5. Cover the seaside paspalum seed stem with about 5-6mm of soil, so that at least one node of the seashore paspalum seed stem is exposed to the ground, and step on the soil firmly so that the seed stem buried ...

Embodiment 3

[0044] 1. In spring, after the temperature stabilizes above 18°C, use a weed groomer to re-weed the seaside paspalum lawn that has turned green. The depth of weeding is controlled at 5-30mm, and the thinned grass stems are collected as seaside paspalum species. Stem (every grass stem contains at least 1 stem node) for later use.

[0045]2. On April 21, low-pruning the bluegrass lawn that needs to be converted is carried out twice, the pruning height is 30mm, and the lawn height after low pruning is kept at 30mm;

[0046] 3. After low pruning of the bluegrass lawn, cut the bluegrass lawn vertically, the cutting depth is 20-30mm, and the cutting distance is 4-6cm;

[0047] 4. Continuously insert a section of seashore paspalum seed stem section containing 1-4 internodes between the soil gaps left after the vertical cutting of the lawn;

[0048] 5. Cover the seashore paspalum seed stems with 5-8mm thick soil, so that at least one node of the seashore paspalum stems is exposed to ...

Abstract

The invention relates to a method for transforming a cold-season lawn into a seashore paspalum lawn, which belongs to the field of gardening and greening construction. Low pruning and punching or square cutting are carried out on the cold-season lawns like Poa pratensis lawns and Fextua arundinacea lawn, the seed stems of seashore paspalum are inserted into the punched holes or cut lances, and then earth covering and watering are carried out to keep the soil humid until the axillary buds on the seed stems sprout and grow into creeping stems on the ground. Utilizing the natural growth habit of the cold-season lawns and the seashore paspalum lawns, the invention adopts a method of hole seeding or drill seeding of the seed stems of seashore paspalum, thus leading the lawn to have the natural transition from the cold-season lawn to the seashore paspalum lawn, and then to a complete transformed seashore paspalum lawn by the time when summer begins. During the whole transformation process, the two grass seeds grow or decline naturally, therefore, the overall lawn coverage can reach one hundred percent, with no obvious drop in quality of the lawn, and the function of the lawn can still held during the reconstruction period of the lawn.

Description

technical field [0001] The invention relates to a method for converting a cool-season lawn into a seaside paspalum lawn, in particular to a method for gradually and naturally converting a cool-season lawn into a seaside paspalum lawn according to the growth habit of lawn plants, belonging to the field of landscaping construction . Background technique [0002] At present, cool-season turfgrasses (perennial ryegrass, bluegrass, tall fescue, creeping bentgrass, etc.) have better cold tolerance, but their heat resistance is relatively poor. Under these conditions, it is obvious that the growth is not suitable, the growth potential is weak, the disease is serious, the quality is reduced, and even death, which seriously affects the landscape and function of the lawn. In addition, cool-season lawns have higher requirements for maintenance and management, and management measures such as frequent pruning, fertilization, irrigation, and control of diseases, insect pests and weeds ar...
