In what season should grass seeds be sown?

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 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.

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

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.

1. Sowing period: master the symbiotic period of about 20 days between grass seed and late rice, and sow it 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.

Lay the base, after the late rice is harvested, and then add 10 15 catties of fertilizer. After the beginning of spring, a small amount of human manure or urea is applied to the fields with poor growth.

Strive to exchange small fat for big fat.

Types of lawn seeding machinery

There are two types of lawn sowing, one is to sow grass seeds on bare land without any lawn, but after land preparation. The other is to reseed grass seeds on the already formed lawn areas that have been damaged or have poor growth.

Lawn seeding machinery mainly includes lawn seed seeder, lawn spreader, lawn spray seeder, lawn precision seeder and lawn reseeder.

Usually, for lawn seeding requirements are not high, spreaders and spraying machines can be used; For lawn sowing requirements, seed drills can be used; For the most precious grass seeds, precision seeders can be used. Turf reseeding machines are often used when reseeding grass seeds in existing turf plots to partially damaged or poorly produced areas.

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.

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.

In the summer, many grass seeds can be sown, such as some warm-season varieties of dogtooth root, Bermuda, Manila, etc., the summer sun is abundant, suitable for the growth of these plants, please call Changjing Seed Industry for details.

Grass seeds can be sown in summer, especially warm-season grass seeds are particularly suitable for planting in summer, and dogtooth root and knotweed are outstanding representatives of warm-season grass seeds, which can grow at high temperatures in summer 35, and are the most prominent grass seed types among all green grass seeds. Other types of grass seeds can also be planted barely in the summer, but they need to be cooled artificially.

So what are the grass seeds that are suitable for summer growth? The grass seeds we commonly use are dogtooth root, broad-leaved grass, clover, etc. Warm-season grass seeds have outstanding high temperature resistance and can grow in an environment of 25-35, so summer planting is more suitable to meet the temperature needs of warm-season grass seeds.

Turfgrass seed planting time.

Gymnosperms are perennial plants that usually germinate three days after sowing and have a growth cycle of about two months. Generally, gymnosperm seeds are suitable for sowing in spring, because it likes a warm environment very much, and the temperature of spring is just right for the growth of gymnosperms.

Turfgrass seed planting method.

1.In general, ground grass is easy to grow. Before planting, it is necessary to choose seeds with full and healthy grains, which can improve the survival rate.

2.After planting the ground grass, you need to water it. It is generally sufficient to ensure that the soil is completely moist.

3.Terraced grasses like light, and the light time should be replenished in time. Generally, it takes about 5 hours of light a day.

Turfgrass seed collection.

Terraced grasses generally do not bloom. Its seeds are collected from April to June each year. Generally, you can pick it off by hand.

The appearance of the turfgrass seed Yunchiko.

Ground cover grass has many seeds, the shape is generally slender, the color is mostly yellow, the weight of the seeds is very small, but the adaptability is relatively strong.

Soak the seeds in cold water for 2-4 hours. Land selection and land preparation: Deeply turn the soil, clean up the debris and gravel in it, and apply sufficient base fertilizer.

Planting in the soil: The seeds are sprinkled on the surface of the soil and then covered with a thin layer of soil.

1. Planting time

Grass seeds are cold tolerant and high temperature resistant, and if the temperature can be controlled, they can be sown at any time, but it is recommended to choose spring planting, because the climate is mild and cool at this time, which is suitable for the growth of grass seeds, and the survival rate is high after planting, and it is also convenient for later management.

2. Treat the seeds

Before planting grass seeds, it is necessary to choose new seeds for planting, if it is two or three years of seeds, even if they germinate, the growth is relatively weak, and then the seeds are germinated, first soak them in cold water for 2-4 hours to improve the germination rate, and then take them out to dry.

3. Land selection and land preparation

Grass seeds are suitable for planting in loose, well-permeable, well-drained soil, first carry out deep turning, clean up the debris and gravel, and then apply enough base fertilizer to improve soil fertility, which is conducive to the healthy growth of plants and more vigorous growth.

4. Plant into the soil

Sprinkle the treated seeds on the surface of the soil and cover with a thin layer of soil, if the temperature is low, cover it with straw to keep warm and moisturize, promote germination, and during germination, water frequently to keep the soil in a slightly wet state.
