How to plant grass seeds and when to plant?

The soil of the plot planted with grass seeds should be soft, breathable and have a high drainage capacity. It is necessary to dig deep into the plot first, and clean up the debris inside by the way. After treatment, an appropriate amount of base fertilizer is applied to improve soil fertility.

Grass seeds have a certain ability to tolerate cold and high temperatures, and if the temperature can be properly controlled, they can be sown at any time. It is recommended to choose a new species and soak it in cold water for 2-4 hours after selection, which can promote faster and neater budding. The plot should be turned over once first, and an appropriate amount of base fertilizer should be applied to ensure that the plot is soft and fertile.

The planting method is very simple, sprinkle the seeds directly on the surface of the soil and cover the thin soil. There should be no shortage of water at the germination and seedling stages, and the soil should be slightly wet.

Grass seeds should be planted after the vernal equinox, after which the temperature rises and the land warms up.

Growth temperature. The optimal growth temperature of warm-season turfgrass seeds is 25 -35.

Grass seed species. Dogtooth root, Bermuda, knotweed, teff, bison grass, carpet grass, and false frugal grass, among others.

Geographical distribution. It is widely distributed in warm humid, warm semi-humid and warm semi-arid climate zones, and is generally widely distributed in the south of the Huai River.

Seeding time. Because warm-season grass seeds can tolerate high temperatures and grow most in environments above 25 degrees, the best time to plant warm-season turfgrass seeds is between May and October, but the specific time depends on the sowing environment. Growth temperature.

The optimum growth temperature for cool-season turfgrass is 15 to 25 .

Distribution. It has good cold tolerance, but it is not resistant to high temperatures, so it is distributed in cool and warm areas, such as the northern cities where I have been, such as the Northeast, Northwest, North China and other places.

Seeding time. Because cold-season grass seeds are generally heat-tolerant, they cannot be sown in the hot summer, and in contrast, germination in the cold winter is not very favorable, so it is more suitable to sow in spring and autumn, such as March and May, and September and November.

The method of sowing grass seeds is as follows:

1. Sowing period: grasp the symbiosis period of about 20 days between grass seeds and late rice, and sow seeds on October 10 and 20.

2. Sowing amount: According to the quality of grass seeds, the sowing amount per mu is generally about 5 catties.

3. Ditching: In addition to opening the side ditch, it is necessary to open the ditch into the word "ten", "twenty" and "well" according to the shape and size of the field, and the ditch should be deep and not too shallow to prevent water accumulation.

4. Fertilization: Before sowing, use 25 kg of superphosphate per mu as the base, and after the late rice is harvested, add 10 15 kg of fertilizer. After the beginning of spring, a small amount of human manure or urea is applied to the fields with poor growth, and strive to exchange small fertilizer for large fertilizer.

1. Select the variety

Before planting the lawn, it is necessary to investigate the planting area, choose the right grass species according to the climate and environment and the use of the lawn. The climate in various parts of our country is relatively different, the south is warm and humid, suitable for planting warm-season lawns, while the north is cold and arid, mainly cold-season lawns, but it can also be mixed sowing, which can make the lawn green period longer and the effect is better.

2. Organize the land

Planting lawn must be tidy up the land, before sowing the planting land will be ploughed again, remove the weeds and gravel in it, to prevent these debris from affecting the growth of the lawn, and then plow the soil finely, apply the appropriate amount of fertilizer, provide sufficient nutrients for it, and then level the ground, so that the lawn can grow more flat and beautiful.

3. Sowing work

The grass seed sowing method is very simple, generally it is directly sown, it can be sown manually or by machine, the seeds are evenly sown, and then covered with a thin layer of soil, and gently compacted, so that the grass seeds are in better contact with the soil, and the root system can take root quickly.

4. Maintenance management

After the grass seeds sprout, the non-woven fabric should be uncovered, the lawn should be watered and fertilized, pay attention to the appropriate amount of watering, there can be no stagnant water, the temperature is high in summer, the water evaporates quickly, and the watering is generally carried out in the morning and evening. If you want to fertilize, you can use organic fertilizer or compound fertilizer, and fertilize according to the growth of the lawn, do not overdo it. In addition, the lawn needs to be properly trimmed after it is formed to make the lawn grow more lush and flat.

In winter, you can choose cool-season grass species (early maturing grass, tall fescue, ryegrass, purple fescue, scissors, etc.); If you're in the south, you can choose warm-season grass species (dogtooth root, baihi grass, knotweed, horseshoe gold, etc.).

Choose the location of the planting lawn, prepare the land and fertilize it in advance, plough the soil, break the soil on the surface, remove the stones, bricks, etc. on the soil surface, make the soil flat, maintain good air permeability and porosity, and apply organic fertilizer to ensure sufficient nutrients, and the fertile environment is more conducive to the growth of grass seeds.

In order to promote better germination after sowing, the seeds are treated in advance, disinfected with a solution of 1/1000 of potassium permanganate, and the seeds are soaked after disinfection. Before sowing, you can water the soil thoroughly, mix the seeds with fine sand, and then sow the seeds evenly, you can use a hand-cranked seeder to sow the grass seeds, and after sowing, you can smooth and roll it to make the seeds better fit the soil.

Precautions for turfgrass seed sowing.

When the lawn is planted, it is generally not recommended to mix the warm-season turfgrasses, because the difference in growth habits between them is relatively large, and the tillering ability is very strong, and the competitiveness is quite different.

It is not recommended to mix cool-season lawns and warm-season lawns directly, mainly because their growth habits are quite different and their needs for some nutrients are quite different. For example, cool-season lawns can grow well in warm and cool spring and autumn, but in summer they will be in a semi-dormant state, with poor disease and insect resistance, and the amount of nitrogen fertilizer needs to be properly controlled.

If it is in the northern part of our country, it can be planted in spring, generally from early March to mid-April, so that it will not affect its normal growth, because the winter in the northern region is very cold, there is no way to plant, otherwise it will affect the normal germination rate.

However, if it is planted in the south of our country, it can be planted in spring, autumn or winter, because the planting time of each grass seed is different, and the climate in the south is warmer than that in the north.

Grass seeds can be planted from the aspects of planting time, germination, land selection, planting, and reasonable water and fertilizer.

1. Planting time.

If it is a warm-season grass seed, the planting time is from May to October, and the temperature should be above 25, so as not to affect the growth of grass seeds due to low temperature. If it is a cool-season type of grass seed, it can be done in spring and autumn, that is, between March and May or September and November, and the temperature should be around 15-25.

Second, carry out germination.

Grass seeds should be germinated before planting, and the most commonly used germination method is to soak them in water, and put them in water before planting, so that the seeds can germinate more uniformly and facilitate later management. Different kinds of grass seeds, germination time is also different, tall fescue grass seeds should be soaked overnight, water control and then continue to dry for a day, the temperature is kept at about 18 28, and germination can be produced in about a week. The seeds only need to be soaked in water for 4-5 hours.

In addition, some grass leaves do not need to be soaked in water, such as dogtooth root seeds.

3. Land selection and land preparation.

Grass seed planting should choose breathable and soft land, before planting to destroy the liquid for land preparation, need to dig deep land, and clean up the stones, bricks and other debris in the land, the ground should be leveled, and apply base fertilizer. Water about 12 hours before planting, and after watering, you can choose to sow seeds.

Fourth, start planting.

When planting, the germinated seeds are sown on the soil, and the seeds are covered with a thin layer of soil, which can then be covered with straw to ensure that the humidity is right. Always observe the moisture of the soil after planting, if the soil is dry, then it needs proper watering to moisturize. When the grass seeds germinate, the mulch should be removed, otherwise it will affect the growth of the seedlings.

During the growth of the grass, it is also necessary to water it in a timely manner according to the dryness of the soil.

5. Reasonable water and fertilizer.

After the grass seed is planted, it needs to be reasonably applied water and fertilizer, and the soil needs to be kept slightly moist every day, so as to facilitate the germination of grass seeds, and during the grass seed growth period, some fertilizer can be sprayed for it to supplement the nutrients required for the growth of grass seeds, and attention can not be applied to thick fertilizer, otherwise it is easy to adversely affect the growth of grass seeds.
