Those with good cold tolerance can plant ryegrass or Dongmu 70. Dongmu 70 rye, also known as winter grass and winter pasture, is a subspecies of winter rye in Gramineae and is an annual or perennial herb. Dongmu 70 has many tillers, fast growth, strong cold resistance, high yield of fresh grass and good quality. Good palatability. Tall plants and high grass yield are ideal green and silage for herbivores such as cattle, sheep, rabbits and grass carp in winter and spring.

trait

1, with developed root system and cold tolerance. The seeds of Ryegrass Dongmu 70 can germinate at the temperature of 0.5-2.5℃, and the germination rate of 2 1 day is 82.23%-84.83%. Stems and tillers were placed in ice at-65438 05℃ for 24 hours, and no freezing injury was found. The optimum temperature of Ryegrass Dongmu 70 is 15-20℃. The critical temperature for stopping growth is 0.4℃, but it is not damaged by freezing. Compared with wheat crops, it has strong tillering ability and developed root system, which is also the reason for cold tolerance.

2. Do not compete with grain, cotton and oil for cultivated land. Make full use of cotton fields in winter leisure season, and add one-season forage from 10 to April and half a year of the following year. It not only improves the income of cotton fields, but also opens up a source of organic fertilizer for agriculture and purifies the environment. 2. The growth period of this grass is 243 days, heading in early April and harvesting seeds in early June. The crude protein content of hay is high, with an average of 15%, which is close to that of alfalfa (18%). 3. Strong adaptability. Drought tolerance, cold tolerance, barren tolerance, no pests and diseases; After sowing, the average temperature is 4.4℃, which can take root and emerge. 4. High plant height and yield. The plant height 1.5 ~ 2m, and the yield of fresh grass per mu is 7000 ~ 8000kg.
