Ryegrass (referred to as ryegrass) is an annual herbaceous forage, with fibrous roots, base clusters, plant heights of 90 to 130 cm, leaf lengths and widths, dark green leaves and luster, and arc-shaped drape. Rich in protein, minerals, vitamins, including crude protein content of up to 20%, ryegrass quality, good palatability, cattle, sheep, pigs, rabbits, geese, chickens and other livestock and poultry to eat, but also grass carp Good feed. Ryegrass has great potential for yield increase. Under conditions where the water and fertilizer conditions are better and sowing earlier, the yield of fresh grass per mu can reach about 10,000 kilograms. The general fertilization management level is about 5000 kg per mu. Ryegrass has a warm and humid climate, fertile soil, and suitable for both viscous and red soils. The optimum soil pH is 6 to 7.
The ryegrass can be sown in spring and autumn. The number of harvests in autumn sowing is higher and the total yield is higher. Spring sowing can prolong the harvesting period, and the grass is fresh, but the total production is low. The sowing date for autumn sowing is from early September to late November and spring sowing in early February.
Seeding operation before sowing Mushi circulatory 1000 to 1500 kg. If there is no organic fertilizer such as circulatory fertilizer, 25 to 30 kg of calcium magnesium phosphate fertilizer can be used as basal fertilizer. After fertilization, plough the land to do the trick. The ryegrass seed is small, and it is required that the buckwheat noodles be flat and no large clods. The seeding method is drilled or broadcast, but it is convenient for management and it is better for drills. The drill requires 7-foot opening and 6-inch seeding. The amount of mu for use is about 1.5 kg. If there is little rain during the sowing period or if the soil is drier, soaking seeds with fresh water can be used for 2 to 4 hours in order to facilitate seedling emergence and increase the rate of seedling establishment; applying a small amount of nitrogen fertilizer can speed up regeneration and increase yield, and it is necessary to pay attention to the hazards of tigers and earthworms at the seedling stage. If found to use "toxic silk" pesticide control.
The height of the harvested ryegrass grass is about 30 cm. The sowing time, the number of times and the output are related to the fertilizer and water management conditions. In the early autumn, the seeds can be cut 1 or 2 times during the year, and the next spring can be cut about 4 times. If planted in October, if it is well managed, it will be cut once a year and cut two or three times after the year. Spring sowing, can be cut 3 times in early June. Farmers can arrange the sowing time reasonably according to the feeding condition of livestock and poultry.
The households implementing the Reform and Demonstration Project of Agricultural Science and Technology Extension System in Fengyi Town had improved milk production after feeding ryegrass, and the effect was obvious.
Ryegrass planting technology
Fengyi Town cultivates 800 hectares of ryegrass per year, produces 3-4 tons per mu, and has a total output of 2,400-3,200 tons. After implementing the reform and demonstration project of agricultural science and technology extension system this year, farmers’ enthusiasm for raising cattle has increased and planting area has increased to 1200 acres. The introduction of ryegrass planting techniques in Fengyi Town is as follows:
