What is the yield of ryegrass planting in winter

The annual production of perennial ryegrass is around 8 tons

1. Land selection and land preparation

Ryegrass is an annual grass forage, with strong adaptability, high yield, alkali tolerance, barren resistance, cold resistance, resistance to diseases and insect pests, more tillers, strong regeneration ability, high requirements for water and fertilizer, and should be planted in loose and fertile, well-drained soil plots. Before sowing, the soil should be turned over to make the soil more finely fragmented, and appropriate base fertilizer should be applied, generally 5000 kg of soil miscellaneous fertilizer, 40 kg of superphosphate, and 25 kg of ammonium carbonate. <>

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.

One acre of planting 8 12 kg of ryegrass seeds, in the south can bring about 30,000 kg of mu yield, and in the north mu yield is slightly lower, can only have about 25,000 28,000 kg of mu yield, of course, more fertilization, more watering and scientific management can also improve the yield of ryegrass per mu.

Perennial ryegrass is planted at temperatures ranging from 8 degrees Celsius to 25 degrees CelsiusIt is difficult to germinate when it is below 5 degrees Celsius or above 35 degrees Celsius, and it grows most vigorously when the temperature is around 27 degrees Celsius, and when the temperature reaches minus 18 degrees Celsius, perennial ryegrass begins to freeze and cannot continue to grow, and in severe cases, it is possible to freeze to death due to cold.

Moistened ryegrass has ryegrass planting techniques and **.

Perennial ryegrass prefers a cool, humid climate, and is suitable for growing in areas with cool summers and less severe winters. It is difficult to tolerate the low temperature of -15, and 10 and 27 can be suitable for growth. 35 Above are susceptible to withering and death.

It is not shade tolerant, can tolerate moisture, is not drought tolerant, high temperature and drought in summer are extremely unfavorable to growth, likes fertilizer and is not barren, suitable for cultivation on soil with good drainage, moist and fertile, and pH value of 6 7. Ryegrass prefers cool, humid climates. It is suitable for growing in areas with cool summers and not too cold winters.

About 10 can grow well, below 27 is the suitable temperature for growth, 35 is poor growth. Strong sunlight, short sunshine and low temperature are beneficial for tillering. If the temperature is too high, the tillering stops or dies in the middle of the process.

Ryegrass has poor cold and heat tolerance and is not shade tolerant. It can grow for more than 2 years under suitable terroir conditions, and is generally only used as over-yearning forage in China.

Ryegrass seeds are generally sown at a density of about 20 25 grams per square meter, but this density standard is not set in stone depending on the sowing method and the sowing area.

The planting density of ryegrass also depends on the variety of ryegrass, seed quality, germination rate, planting conditions, soil preparation and seedling management. Excessive sowing will lead to over-dense seedling, which will not only waste costs, but also increase the competition of ryegrass for nutrients, water and light, resulting in poor growth of seedlings and easy to be attacked by diseases. If the amount of sowing is too small, it will prolong the time for ryegrass lawn to be formed.

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.

Seeding 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.

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.

The annual output of one acre of land is about 5 tons.

Moistening ryegrass has ryegrass seeds** table, planting techniques, etc.

Under conventional planting, the average yield of ryegrass is about 20,000 catties of mu, but because of the different trap wheels, methods and management methods during sowing, the specific yield will also have certain differences, so it needs to be determined according to the actual situation. In order to improve the yield of ryegrass, it is necessary to apply sufficient basal fertilizer in combination with fine land preparation, and the grass seeds should be mixed with calcium, magnesium and phosphorus fertilizers, and then sprinkled in the prepared plot and covered with soil.

1. Output. Wang Xin Under conventional planting, the average yield of ryegrass is about 20,000 catties of mu, but the sowing time, method and management methods are different, and the yield of ryegrass will also have certain differences, so the yield of ryegrass needs to be determined according to the specific situation.

2. Ways to improve yield.

1) Before sowing, it is necessary to prepare the land finely and apply sufficient base fertilizer, generally 2000-3000kg of farm fertilizer can be applied per mu, or 40kg of nitrogen, phosphorus and potassium compound fertilizer.

2) When sowing, it is required that there should be no stagnant water in the soil, but it should not be too dry, which is easy to affect germination.

3) Before sowing, the grass seeds need to be mixed with calcium, magnesium and phosphorus fertilizer, and then sprinkled in the prepared plot, and then covered with fine soil.

4) It is necessary to pay attention to watering at the seedling stage, and need to be watered frequently in drought, the land should be wet and watered thoroughly, and the weeds in the field should be removed in time.

2. Can ryegrass be planted all year round?

1. Can ryegrass be planted in all seasons?

Ryegrass can generally be grown all year round, but it needs to be cooled down in the summer, as ryegrass seeds tend to die in high temperatures.

2. Precautions for planting.

1) When sowing, you need to choose a good sowing date, ryegrass likes a warm and humid climate, the appropriate temperature for seed germination is above 13 °C, when the temperature is above 10 °C, seedlings can usually grow, so the sowing period of ryegrass is longer, both autumn and spring sowing.

2) If it is sowing in autumn, it can usually be sown from mid to late September to early November, and the sowing time can not be too early, if it is sown too early, because the temperature at this time is relatively high, which is not conducive to seed emergence.

3) 45-50 days after sowing, the first harvest of ryegrass is carried out when the height is 40 cm, leaving 3-5 cm high. It should be noted that at the time of the first harvest, it is necessary to harvest in a timely and comprehensive manner to promote the growth of tillers. At the same time, it is necessary to pay attention to top dressing, top dressing is generally carried out 2-3 days after harvesting, generally each time you can top urea 5-8kg, or farm fertilizer 100-200kg, dilute it into an aqueous solution and then evenly water.

<> the yield of ryegrass per mu in the south is generally about 30,000 catties, and the yield per mu in the north is generally about 25,000-28,000 catties, and its yield can be appropriately increased if properly managed. Ryegrass is a perennial herbaceous plant belonging to the order Poaceae, Poaceae, ryegrass family, ryegrass genus, ryegrass species, and it is also an excellent forage grass, which is now widely cultivated all over the world.
