How many catties of perennial ryegrass grass are planted in an acre of land?

Ryegrass is a kind of cool-season lawn, like a cool and humid environment, the suitable sowing time is spring and autumn, the sowing amount of one acre is 12 15 catties

1. Perennial ryegrass likes a cool and humid climate

Perennial ryegrass is a kind of grass lawn plant species, it likes cool and humid climate, suitable for growing in areas with cool summer and warm winter, and has poor cold and heat tolerance.

2. It is very important to take drainage measures when planting

Ryegrass cannot grow without water, it cannot survive in an arid and water-scarce environment, but too much water is not good, and the soil is too waterlogged and the plants are flooded, so it is important to take drainage measures when planting.

3. Perennial ryegrass has a high yield and is a forage grass with high economic value

However, its growth cycle and regeneration ability are very strong, ryegrass can grow for more than two years under suitable environmental conditions, and the yield is very high, it can be harvested two or three times a year, and it is a pasture with high economic value.

4. Ryegrass can also be used as a green lawn and has certain practical value

Ryegrass can also be used as a green lawn, often planted in parks, courtyards, golf courses, football fields and other places, not only ornamental is very strong, but also has a certain practical value, can green the environment, improve air quality, and provide great help for urban greening construction.

5. Ryegrass is a high-quality pasture grass

The practical value of ryegrass is much higher than that of other lawn plants, it can be used for urban greening construction, improve environmental conditions, and is a kind of high-quality pasture, planted in grassland grazing areas, can also play a very important role in the development of animal husbandry, is a plant worth planting.

A pound of ryegrass can be sown about 50 60 square meters if it is used for breeding, about 25 square meters for greening, and about 10 square meters for lawn.

It depends on what kind of forage grass variety, such as 10 catties of domestic one acre of land, 4 catties of imported one acre, domestic seeds at 5 yuan a catty, imported seeds at 12 yuan a catty, and moistening ryegrass has seeds, planting technology and technology.

An acre of annual ryegrass needs about 10 catties, a green ryegrass is about 20 catties per acre, and a lawn ryegrass is about 30 catties per acre。One square is about 20 25 grams.

What factors affect the amount of ryegrass seeds to use?

Varieties, different varieties of seeds are not the same.

Region: Ryegrass is a cool-season type of ryegrass, and the amount of water used in the north is less than that in the south: the amount is less in places with sufficient moisture.

Sunlight: Use more in sunny places.

Before sowing per mu kilogram per mu with 50 kg of calcium and grass seeds mixed evenly and then pulling the line to sow seeds, the seeds can be soaked for 5-8 hours before sowing, and the epidermis water is dried for sowing, and the seeds and soil are fully contacted with a nail rake after sowing, and irrigation is carried out after sowing, and the irrigation can not be flooded to prevent the seeds from being washed away by water.

This variety, different varieties, different quantities, imported seeds per acre of land 4 catties, domestic seeds per acre of land 8 catties.

Moistened ryegrass has ryegrass seeds**table, planting techniques**.

Ryegrass yields about 8-10 tons per mu per year, harvested about 4-5 times a year, and the planting method is as follows:

1. Land selection and land preparation

2. Sow seeds

1) Generally in spring or autumn, the seeds should be placed in the sun for about 1 hour before sowing, and then soaked in water for 12 hours, so that the seeds can fully absorb water and germinate in advance.

2) sowing using the most strip sowing method, generally per mu sowing kilograms, depending on the soil moisture, land quality, seed germination rate and so on as appropriate, after sowing to cover a layer of soil and water through.

3) If the weather is dry or the soil is dry, it should be properly irrigated. The seeds germinate quickly, pay attention to weeding after germination, you can spray herbicides, and there will be a large area of grass in less than a month.

3. Post-management

Clean up the weeds in time during the growth of ryegrass seedlings, and properly loosen the soil and fertilize, fertilization is best carried out after harvesting to avoid grass stubble being burned.

4. Harvesting

The grass is cut about 50 days after sowing, and the grass is harvested regardless of the strength of the growth when the grass is mowed. After each interval of 20-30 days to harvest once, after harvesting to carry out watering and fertilization, to supplement the nutrients needed for growth, rye grass trampling resistance is also very good, natural grazing is also possible, the same can grow quickly, in order to solve the problem of lack of green fodder in winter, you can harvest after the green storage.

There are also many varieties of ryegrass, including Yaqing ryegrass, winter 70 ryegrass, tetraploid extra-high ryegrass, etc., different varieties, different soil conditions, different water and fertilizer conditions are the main factors affecting the yield. Generally around 5000-10000 catties.

The amount of fresh grass of 3000-4000kg also depends on your management.

How many seeds do ryegrass need for an acre of land.

It depends on what variety, such as 4 catties of seeds per acre of imported seeds; Domestic and 10 pounds of seeds per acre.

Moistening ryegrass has a table of ryegrass planting, planting techniques and technology.

OK. Perennial ryegrass can be sown in March, and in March it is spring, the climate is relatively warm, and ryegrass also likes to grow in a warm environment, so the climatic conditions in March are in line with the growth habits of ryegrass.

Perennial ryegrass cultivation method:

1. Planting time

Perennial ryegrass is a cold-season grass species, with good cold tolerance, but not heat resistance, so it must not be planted in summer, most of them are planted in spring and autumn, which will be good for seed germination and growth, and the specific planting time should be decided according to the climate of each place.

2. Soil environment

It is best to plant perennial ryegrass in loose and fertile soil, and before planting, the soil should be prepared and turned over to remove weeds and debris, and the bottom fertilizer should be applied to water enough to maintain sufficient nutrients and water to make the seed germination rate higher.

3. Sowing method

Perennial ryegrass seeds are sown in strip sowing, first set the row spacing, about one kilogram of seeds per acre, spread the seeds evenly in the soil, cover the soil layer with a thickness of about one centimeter, and finally water thoroughly, you can.

This question is not very specific, but it is a question 1Isn't "now" the time for planting? Can it be planted at this time?

2.What is perennial ryegrass used for? Is it profitable?

Now "Can you plant?" 3.Is this plant suitable for planting in the questioner's place, and can it be planted?

Ryegrass is an important cultivated pasture and green manure crop. Most of the ryegrass grown in China is a perennial sparse bush herbaceous plant. The height of the plant is 80 100 cm.

The fibrous roots are well developed and are mainly distributed in soil layers up to 15 cm deep. The stems are erect, smooth and hollow, and light green in color. The number of tillers per plant is generally 60 100, and the number can reach 250 300.

Ryegrass grows in environment, and the pH of suitable soil is 6-7. The diurnal temperature is 12 -27 The regeneration ability is strong, the light is strong, the sunshine is short, the temperature is low for tillering, and the shading is not good for the growth of ryegrass. Ryegrass is moisture-tolerant, but it is not conducive to growth due to poor drainage or high water tables.

Perennial ryegrass is a very economically valuable cultivated forage. It is cultivated in New Zealand, Australia and other foreign countries, and is a forage for cattle and sheep.

1. Soil environment

Although perennial ryegrass is very adaptable, it is more suitable for growing in its own loose, airy and fertile soil, and a good environment can make the plant grow better. Before sowing, the soil should be deeply turned and fertilized, and then the soil should be broken and leveled.

2. Sowing time

Perennial ryegrass seeds are mostly sown in early spring or early autumn, the climate begins to warm up in early spring, the soil thaws, which is very suitable for seed germination, and autumn sowing should also be early, and then gradually become cold, which will not be conducive to seed germination. Of course, the climate varies from region to region, and the timing of planting varies from place to place.

3. Sowing work

Perennial ryegrass seeds can be sown in the way of sowing, to spread the seeds evenly in the soil, about 30 40 grams per square of seeds, not too much or too little, the sowing depth can be about one centimeter, after the sowing is completed, it should be gently pressed with a tool, and sprayed with some water to keep the soil moderately moist, which is more conducive to seed germination.

Perennial ryegrass has many uses, first of all, it has a good greening effect, the color is light green, it grows vigorously, and can be used for the construction of green lawns. Secondly, perennial ryegrass has a well-developed root system and flexible grass, which is a good slope protection lawn, which can prevent rainwater from scouring the soil after planting, maintain water and soil, and protect the environment. Finally, it can also be used as pasture grass, which is highly nutritious and suitable for livestock.

Because of its so many uses, perennial ryegrass is grown in many places.

Perennial ryegrass is a short-lived perennial forage grass of the genus Ryegrass of the family Poaceae, with a general lifespan of 3 to 4 years. Perennial ryegrass is characterized by fast growth and high grass yield. It is suitable for growing in areas with cool summers and not too cold winters; It is most suitable for growing in areas with annual precipitation of 500 to 1500 mm; It is not resistant to heat, and if it is above 35 years old, growth will be stunted; It is not tolerant to severe cold, intolerant to low temperatures of -15, and prefers well-drained soil and clay.

Perennial ryegrass can only be sown in spring in cold areas in winter, summer sowing in dry areas in spring, and can be sown in spring and autumn in the Yangtze River basin and all places south of it. The row spacing of strip sowing is 15 30 cm, the sowing depth is 2 3 cm, and the sowing rate is 1 kg per mu (667 m2).

Perennial ryegrass is a forage grass with high economic value, with lush stems and leaves, tender and juicy, which is preferred by all kinds of domestic animals, and is a high-quality forage for horses, cattle, sheep, pigs, poultry, rabbits and herbivorous fish. High yield, strong regeneration capacity, mowing 3 4 times a year, per mu (667 m2) can produce 3000 4000 kg of grass. It is suitable for green fodder and hay preparation.
