In the construction of modern gardens and landscapes, lawns have become an indispensable part and can be seen everywhere in courtyards, parks, squares, streets, and communities. The lawn has a wide range of uses. It can be used as a material for landscape landscaping, as an accessible leisure place, and can also be used for mountain protection.
Then, if you want to understand the lawn, you must understand the common sense of grass species classification, which can be analyzed from 5 aspects:
1. According to the growing season
can be divided into warm seasons Type turfgrass and cold season turfgrass.
Warm-season turfgrass: the most suitable growth temperature is 26℃-35℃, and it will be dormant below 10℃. Warm-season turfgrass are more suitable for lawns in areas with higher climates such as South China and Hainan.
Commonly used warm-season turfgrass are: Manila, bermudagrass, zoysia , bison grass, horseshoe gold, white clover, etc., which tend to wither in winter. , Green in spring, summer and autumn.
Cool-season turfgrass: The most suitable growth temperature is 15℃-25℃, and the growth is slow above 30℃. Cold-season turfgrass are generally used in areas with colder climates such as Central China and Northwest China. Commonly used cold-season turfgrass are: ryegrass , tall fescue , cut bentgrass , bluegrass , red fescue and so on.This kind of grasses in the south are often afraid that the high temperature will not pass the summer and die, so they need to be replanted in October to bring you green vitality in winter.
2. According to different families
can be divided into gramineous turfgrass and non gramineous turfgrass. In the past, lawn plants were mainly composed of grasses of the grass family, but in recent years it has developed into non-grass plants.
Gramineae turfgrass: accounted for more than 90% of the turfgrass. The turfgrass of the genus Bentgrass, Lolium, Poa, Zoysia, and Fescue are all Gramineae.
Non-graminaceous turfgrass: Commonly used are Carex sylvestris, Moss tenuiflora, white clover, red clover, etc., which can be used as turfgrass plants; secondly, there are creeping horseshoe gold, turfgrass_ span20span, Thyme can be used as garden flower beds, modeling and ornamental lawns.
3. According to the purpose of the lawn,
can be divided into ornamental turfgrass, ordinary green turfgrass, soil-fixing slope turfgrass, sports field turfgrass, etc.
Ornamental turfgrass: mostly used for ornamental lawns, but also Used for ornamental decoration. The leaf color is emerald green, with good viewing effect, thin leaves and good hand feeling. Commonly used ornamental lawn grasses include white clover, bluegrass , perennial ryegrass and so on.
Common green lawn grass: generally used for recreation lawns, for tourists to walk, rest and carry out outdoor activities. Trample resistance and strong resistance. Commonly used common green lawn grasses include Zoysia japonica , carpet grass , bermudagrass, bluegrass, bison grass, etc.
Soil-fixing and slope protection lawn grass: used for environmental protection lawns, laid on slopes and water banks, used to prevent soil erosion and endure extensive management. Commonly used soil-fixing and slope protection lawn grasses include Zoysia, bison grass, tall fescue and so on.
Sports field lawn grass: generally used in football fields and tennis courts. It is elastic, resistant to frequent trampling, and has strong resilience. Commonly used sports field lawn grasses are: Zoysiagrass, Poa, tall fescue, perennial ryegrass and so on.
4. Classified by height
can be divided into low turfgrass and tall turfgrass.
Low turfgrass: common Zoysia grass, Zoysia tenuifolia, bermudagrass, buffalo grass, thrift grass, carpet grass and so on.
Tall turfgrass: common tall fescue, bluegrass, ryegrass, bentgrass and so on.
5. According to the width of turf grass leaf
can be divided into fine-leaf turf grass and broad-leaf turf grass.
Fine-leaf turfgrass: common bentgrass, Zoysia tenuifolia, Poa, Bison grass, Fescue tenuifolia and so on.
Broad-leaf turfgrass: common zoysia grass, carpet grass, false thrift grass, tall fescue and so on.
In our daily life, we often see lawns in parks, communities, and some sports fields that are evergreen all the year round, and the lawns at home begin to wither when the weather is cold.
These four-season evergreen lawns all use mixed and cross-seeding methods
Mixed sowing : Sown cold-season grasses on warm-season lawns in autumn, and warm-season grasses on cold-season lawns in spring. Grass seed.Commonly used mixed sowing methods are: Bermuda and ryegrass, ryegrass and tall fescue, tall fescue and bluegrass, etc. The two kinds of mixed sowing can play a complementary role, so that the green period is greatly extended. For mixed sowing, the dormant warm-season turfgrass should be cut in the fall, and the cold-season turfgrass should be cut before the summer. The time of mixed broadcasting is generally the most suitable in October, but it should be adapted to local conditions, referring to the local daily average temperature below 23°C. The number of seeds per square meter of mixed turf is generally between 15-30g, and the appropriate number of seeds should be selected according to different growth environments.
Live broadcast: is also called rebroadcast and follow-up broadcast. That is, cold-season grasses such as perennial ryegrass and annual bluegrass are sown on warm-season lawns before the onset of winter. The effect of cross-seeding and mixed-seeding is the same, both of which reach the evergreen lawn in all seasons.
These two methods can prolong the green period of the lawn. When we use these two methods, we must choose the varieties of cross-seeding or mixed seeding according to the variety of lawn grass, as well as the local climate and seed growth environment. , Time and quantity can achieve good results.
