A successful lawn is inseparable from careful management, but the work steps during establishment are also extremely important.Many problems encountered in lawn management may be directly or indirectly related to mistakes or negligence in the lawn establishment process. If the work during establishment is done carefully and thoughtfully, the management work after establishment will also be Correspondingly, it is more worry-free, but if the planting is improper, it may cause problems such as weed breeding, pest damage, poor soil conditions, uneven growth of lawn grass, etc. to varying degrees. Therefore, like other general construction projects, lawn planting should also have certain procedures, mainly: site preparation, grass seed selection, lawn propagation, etc. For projects that need to be delivered for use, you must also be responsible for the care and maintenance of young lawns before delivery. Managed to produce a high quality lawn.
The process of planting a new lawn
Planting a new lawn is a complex and methodical task. It requires a series of constraints on the establishment based on different regions, different site conditions, different requirements and other external factors. But in general, the main Make appropriate changes to the following aspects according to different conditions.
1. Choose the appropriate lawn grass species
The selection of lawn grass species is affected by many factors. In addition to customer requirements and seed dealer recommendations, the most important thing is that the selected lawn grass should be adapted to the local climate and soil conditions. For example: if the sowing land is semi-shady, shade-tolerant turfgrass should be selected. The selected turfgrass should also implement a series of management measures such as pruning, fertilization or irrigation. It is most taboo to ignore the planting site and the planting site due to personal preferences. Blindly introducing species due to climate differences in the place of origin and doing large-scale breeding and construction will not only result in failure, but may also cause a large amount of economic and other losses. When introducing or adopting a new turfgrass variety, you should try to consult relevant experts or grass seed dealers. If necessary and possible, you should generally conduct a small-area planting experiment first to avoid unnecessary economic losses. Specific selection requirements and criteria are described later.
2. Preparation of flat bed
There are different types of lawns, but the requirements for the lawn bed are the same. They all need a soil texture that can well adapt to the growth and development of turf grass. Therefore, if the conditions of the lawn bed are not ideal, a series of seedings need to be carried out on the lawn bed soil. Preparatory work must be carried out in order to ensure that the soil has good drainage, high flatness, and suitable pH. At the same time, soil fertilization and organic matter addition must be carried out. However, the specific construction work of the lawn bed is related to the environmental conditions of the lawn site, such as the local The climatic factors will affect the design and installation of the irrigation and drainage facilities of the flat bed. The specific characteristics of the soil will also affect the fertilization and application of soil conditioners. Therefore, in the preparation of the flat bed, the environmental conditions of the opposite site must also be considered. Make a detailed and clear investigation.
3. Propagation of lawn
The selected lawn grass can be propagated vegetatively or by seed. Each has its own advantages and disadvantages, but regardless of the type of propagation, a certain time and method need to be selected.
(1) Time selection for lawn propagation
Theoretically, lawn propagation can be carried out all year round, but in order to have a high success rate in establishing lawns, a certain season is often selected. Generally speaking, as long as the temperature during lawn propagation and the temperature 2 to 3 months after propagation The temperature is suitable for the growth and development of lawn grass. In cooler areas there is an ideal season – early spring, late summer or early fall. Generally speaking, the propagation of cool-season turfgrass can be chosen in late summer and early autumn, while the propagation of warm-season turfgrass can be chosen between late spring and early summer. If spring is chosen, sowing should be done as early as possible. , so that the seedlings can grow robustly and establish a flat surface as soon as possible before the hot weather comes, so as to prevent the invasion of summer weeds. The best season for seedling growth is often late summer or early autumn. In these two seasons, weeds are not very serious in summer, and the temperature and rainfall are more conducive to the growth of turfgrass. If it is well established before the cold winter season, Once the lawn construction work is completed, the turfgrass planted in the cool season can still withstand the cold of winter.However, when building a new lawn on a flat bed, it is wrong for the lawn manager to insist that once the sowing land meets the conditions, it must be sown regardless of whether the sowing date is ideal. If a flat bed must be built at this time, in this case, then Special efforts should be made to reduce the undesirable effects of out-of-season sowing, such as mulching. In order to protect the seedlings from losses caused by heat and dryness of the soil surface, the soil surface should be lightly covered with straw or other crops such as (straw), and watered carefully. These measures are beneficial to sowing in late spring and early summer. Planting in mid-summer is often not easy to achieve success (except for the use of a few warm-land grass seeds such as zoysia and bermudagrass to build lawns). Good judgment can help you extend planting until late August. In winter in most parts of the South, when green coverage is essential (such as golf courses, etc.), planting ryegrass can provide a temporary satisfactory lawn.
In warmer areas, the ideal planting season is spring (when temperatures warm enough for lawns to germinate). This early seeding will keep your lawn grass green throughout the growing season before the colder months arrive. When establishing lawns in the tropics, there is a wide range of selectivity in terms of sowing dates. In fact, this area can be seeded at any time during the summer if moisture is provided for seed germination and turfgrass growth.
(2) Mixed sowing of cold area turfgrass
Areas with cold winters (such as most areas in northern my country) usually use mixed sowing. Generally speaking, the effect of mixed turfgrass sowing is more satisfactory than that of single sowing. However, mixed sowing is rarely done in warm areas. This is because most good-quality warm-land turfgrasses use vegetative propagation rather than seed propagation. At the same time, competition among them is quite fierce. From this perspective, they are not suitable for mixed sowing. Mixed sowing in the north has many advantages. The actual growth of the first turfgrass in the mixed sowing combination varies during the growing season. Therefore, from early spring to late autumn, the growth of mixed sown lawns can be more uniform. At the same time, mixed sowing can also prevent the rapid spread of diseases. , thereby reducing global damage.
When mixed sowing lawns in cold areas, if the proportions of each species are appropriate (you can seek advice and suggestions from grass seed dealers), you can first use temporary turf grass (preferably perennial ryegrass) to quickly occupy the soil, and then While the growth and development of this turfgrass is slow, more permanent turfgrasses gradually grow vigorously, forming a stable lawn. Italian ryegrass (garden ryegrass) is not suitable for mixed planting because it grows so vigorously that it crowds out other slower-growing lawn grasses. If shade-tolerant turfgrass is needed in the mix, meadow fescue (rather than oxtail) can account for 15% of the mix, which can create conditions for rapid growth. This is because meadow fescue is shade tolerant while ryegrass is not. Small chaff grass can also be included as a component of the mix, but the total proportion of all fast-growing lawns (ryegrass or meadow fescue plus small chaff grass) should not exceed 25%. Lawn mixes composed of inexpensive seeds often include an excess of temporary turfgrass (ryegrass, meadow fescue, or chaff grass) and a reduced proportion of relatively expensive permanent turfgrass. The higher the proportion of temporary turfgrass seed contained (approximately 25%), the less chance there is of permanent turfgrass forming stable turfgrass.
Establish a general lawn on soil with adequate sunlight and moderate fertility. Cold-land perennial turfgrass can be bluegrass, purple fescue and tenuous bentgrass, or two or more bluegrass and purple fescue can be used. Variety. Weak bentgrass seeds should not contain creeping bentgrass seeds to avoid tangles that could cause trouble in the future. As mentioned before, since the growth and development characteristics of warm-land turfgrass are different from those of cold-land turfgrass, single sowing is usually used instead of mixed sowing between them-spinner fertilizer spreader. Of course, this does not object to the mixed sowing of cold-land and warm-land turfgrasses that have been successfully carried out in some areas.
When establishing partially shade-tolerant lawns in cooler areas, thick-stemmed bluegrass should be substituted for grassland bluegrass and, if mixed, purple fescue should be included, while downy bentgrass should be used instead of thin bentgrass. Pasture fescue and brangrass should be fast-growing local turfgrasses in mixed turfgrasses. Among warm-land turfgrasses, obtusegrass is the most shade-tolerant, while carpet grass is less shade-tolerant.
In cold areas with poor soil and slopes, the mixed lawn should contain a high proportion of small bran grass, and the number of purple fescue should also be appropriately increased. At this time, the dependence on bluegrass should be reduced. Among warm-land turfgrasses, bermudagrass is an ideal species in these areas because of its high drought tolerance.
