Ryegrass—Dongmu 70

Dongmu 70 is an annual gramineous forage with strong adaptability, high yield, alkali tolerance, barren tolerance, cold tolerance, resistance to diseases and insect pests, many tillers, and strong regeneration ability.

Winter grazing 70 ryegrass generally yields about 3000 kilograms of fresh grass per mu, up to 5000 kilograms. Its stems and leaves are delicate, rich in nutrients and good palatability. It is ideal forage and silage for herbivores such as cattle, sheep, rabbits and grass carp in winter and spring. It creeps during the seedling stage. In spring, the stems are firm and not easy to lodging, and the height is 150 cm to 180 cm. After maturity, the heads of the ears are slightly drooping, and the middle and upper stems and leaves are green. It can be used as forage. Dongmu 70 has high nutritional value, rich in amino acids, and contains a variety of trace elements, high protein, high fat and high lysine. Winter grazing has 70 tillers, fast growth, strong cold resistance, high fresh grass yield, good quality, good palatability, tall plants and high grass yield.

1. Features

1. Developed root system, resistant to severe cold. Compared with other wheat crops, winter grazing 70 has stronger tillering power and developed root system, which is also the main reason for cold tolerance.

2. Do not compete for cultivated land with grain, cotton, and oil. Make full use of the winter slack season of cotton fields. From October to April of the following year, one season of forage will be increased in half a year. It not only increases the income of cotton fields, but also opens up a source of organic fertilizer for agriculture and purifies the environment.

2. Cultivation points

1. Shallow tillage and stubble elimination. After harvesting autumn crops such as cotton, red taro, soybeans, shallow plough 1 time, turn out the residual roots left by the previous crops in the ground, so as to fertilize and restore soil fertility. Shallow ploughing accompanied by raking the ground 1-2 times, can maintain moisture and remove stubble, Prepare for fertilization and deep plowing.

2. Apply foot fertilizer. Because ryegrass produces high grass yield and requires more nutrients, it must be adequate base fertilizer. The amount of fresh ryegrass is closely related to the amount of fertilization. Generally, 5,000 kilograms of soil and miscellaneous fertilizers, 40 kilograms of superphosphate and 25 kilograms of ammonium bicarbonate are applied per mu. The soil and miscellaneous fertilizers are broken up and spread evenly, and the chemical fertilizers are sprinkled with the furrow and covered with the plow in the soil.

3. Deep ploughing and fine rake. Tillage depth of 20-22 cm makes the soil in the cultivated layer loose and mature, which is beneficial to the growth of the root system of ryegrass and increases the ability of the root system to absorb water and fertilizer. Asking to plow all the way to the side without lying down. While ploughing and raking, artificially break large blocks of soil to reach fine soil level.

3. Seeding guidance

1. Sowing period. The sowing period is from late September to early October, within this range, it should be early but not late, otherwise it will affect the improvement of ryegrass products.

2. Broadcasting method. The general sowing depth is 3-5 cm, and the specific depth depends on the moisture content, soil quality, and soil preparation.

3. Seeding amount. Generally sown 6-10 kilograms per mu, depending on the soil moisture, soil preparation quality, and seed germination rate.

Four, field management

1. Field tillage and weeding. Combine cultivating to eliminate weeds in time, increase ground temperature, and promote germination and growth.

2. Fertilize. In order to promote greening, accelerate plant growth, and replenish soil fertility, topdressing fertilizer should be applied in time after each cutting, generally 15-20 kg of ammonium bicarbonate per acre hole. Fertilization should be even, and the depth of application should be 6-8 cm. After application, cover the soil with your feet and be careful to prevent the volatilization of chemical fertilizers.

3. Irrigation. In the case of relatively dry weather, irrigation must be carried out, which is combined with fertilization.
