Planting time and methods of ryegrass growth characteristics of ryegrass

Ryegrass is a kind of gramineous plant, which has strong adaptability to the environment and can be planted in both the south and the north of China, but the climate in the south is milder, and the planting effect of ryegrass in the south is relatively better. Ryegrass is a kind of forage grass that is very suitable for poultry, and understanding how ryegrass is grown can help all parties to make a better profit.

Planting time of ryegrass

Can be sowed in spring or autumn, we usually use autumn sowing, the sowing time is from the first ten days of August to the end of November, and the most suitable sowing time is from September to October. Generally, the earlier the sowing, the higher the grass yield. The sowing method is generally scattered or strip sowing, with a sowing amount of 1.5-2kg per mu, and the seeds can be directly mixed with calcium magnesium phosphate fertilizer after sowing, but in case of dry weather or dry soil, it must be irrigated in time, otherwise it will affect seedling emergence. Before sowing, it is best to soak the seeds in the sun for 1 hour, soak the seeds in warm water for 12 hours, or 1% limewater for 1 hour, and then mix the seeds, so that the seedlings can emerge early and improve the seedling emergence rate. Interplanting in single-cropping rice field can be sown at 7 min and 8 days before harvest.

Super tall ryegrass likes warm and humid climate, and the suitable germination temperature of seeds is 13 ℃-20 ℃. It is difficult to germinate when it is lower than 5 ℃ or higher than 35 ℃. It can be planted from February to November, and the best planting time is from early April to mid-May and from mid-June to the end of July.

Planting methods of ryegrass

Ploughing and ploughing and soil preparation before sowing, combined with 1000 kg of farm manure as base fertilizer. It is suitable to sow in autumn. The row spacing is 15-30 cm, the sowing depth is 1-2 cm, and the sowing rate is 1-1.5 kg per mu. Like nitrogen fertilizer, it is appropriate to apply quick-acting nitrogen fertilizer after each cutting. It can be cut 3-6 times a year. The yield of fresh grass is 4000-5000 kg per mu. Send seeds on the bottom of rice. About 20 days before rice harvest, ryegrass seeds were soaked in water for 5 to 8 hours, picked up and drained, mixed with fine sand and sowed. The sowing rate is 1 to 1.5 kilograms per mu.

Ryegrass likes to be wet and afraid of flooding, so it must be drained and irrigated in time. Ryegrass planting method combined with irrigation and fertilization can greatly improve the yield and quality of ryegrass. Apply sufficient basal fertilizer before sowing, topdressing once at three-leaf stage and tillering stage, applying urea or compound fertilizer 5kg / mu each time. After that, topdressing fertilizer for each harvest, apply urea or compound fertilizer 10kg / mu. In order to prevent the grass from rotting, it is recommended to apply fertilizer 3-5 days after mowing, and each fertilization should be combined with irrigation. In the second year, 15 days before rice transplanting, the ryegrass plough was turned into the soil and retted with water. It is best to plow 5-7 days after mowing the grass.

Cut rice as low as possible, lest rice stubble affect the future harvest of ryegrass. Sending seeds can sow seeds in advance and prolong the growth period of forage grass. The planting method of ryegrass is ploughing and sowing. After the rice harvest, ploughing and crushing the soil, making the bed according to the width of 1.5 to 2 meters, leveling and sowing, or sowing according to the row spacing of 20 to 30 centimeters, the sowing amount is 1 to 1.5 kilograms per mu. After sowing, a shallow rake is suppressed once, so that the seeds are closely combined with the soil, and then irrigation is kept moist.

Growth characteristics of ryegrass

Ryegrass is a grass of the family Gramineae. It grows luxuriantly in spring and autumn, and its grass is tender and succulent. It is a good feed for cattle, sheep, rabbits, pigs, chickens, geese and fish. The grass supply period is from October to May of the following year, and can not grow in summer. Ryegrass has about 10 species of ryegrass, including forage grass and grassland grasses and some poisonous weeds in temperate regions of Eurasia. Ryegrass is about 0.3 ∼ 1 m (1 ∼ 3 ft) tall, with tough, dark green leaves. The spikelet grows on the zigzag axis. Perennial ryegrass (L. perenne) and Italian ryegrass germinate early and are important components in grass seeds collected from pastures and grasslands. Poisonous wheat is often infected by poisonous fungi, and its seeds also contain narcotic toxic ingredients, both of which are very dangerous to grassland animals. Ryegrass belongs to the genus of Gramineae ryegrass, which grows luxuriantly in spring and autumn, with tender and succulent grass and good palatability. It is a good feed for cattle, sheep, rabbits, pigs, chickens, geese and fish. The grass supply period is from October to May of the following year, and can not grow in summer.

Market benefit of raising chickens with ryegrass

Raising chickens with ryegrass can increase economic benefits. Because ryegrass is rich in nutrition and high in crude protein, feeding chickens with ryegrass can meet the needs of chickens. With forage mixed with forage grass, the daily weight of chickens is significantly increased. The survival rate of chickens is also relatively improved, and the overall quality of chickens has been significantly improved. Specific chicken feed formula, the demand for crude protein is different in different periods, the crude protein content is 19.5% in the rearing period, 17.4% in the growing period, and 16.3% in the fattening period.

And the ability to harvest ryegrass is strong and can be harvested repeatedly, so planting ryegrass to raise chickens can reduce the production cost of raising chickens. Chicken breeders generally know that the input cost of raising chickens is not large, and the main investment is spent on raising chickens. It is estimated to be about 80%. Ryegrass grows fast, has many tillers, can endure grazing, is a high-quality grazing forage grass, and is one of the grasses with the highest yield of digestible matter.

Raising chickens with ryegrass makes the chickens green and healthy. In order to meet the nutritional needs of chickens in the process of raising, many chickens are fat and put in a large number of additives, which makes there are a lot of drug residues in chickens. Raising chickens with ryegrass not only meets the nutritional needs of chickens, but also does not damage the health of chickens, and consumers eat more safely and healthily.

Ryegrass chicken is a very scientific way of breeding, so that the chicken raised is not only ecological green, but also can meet the needs of normal development. If farmers can combine the cultivation of ryegrass with livestock farming such as chickens and ducks, it is a very favorable industrial model.
