1. Feeding sweet sorghum Planting time: Spring sowing in mid-March to late April, the ground temperature is 12 °C ~ 18 °C. Land parcels: The selection of high-quality plots for the soil can be carried out in the fall, leveling, or in conjunction with spring planting. Before the site preparation, apply 1,000 to 1,500 kilograms of fertilizer per acre to make base fertilizer. Planting methods: The use of 2020 cm hole sowing, after sowing cover the thickness of 2 to 4 cm, seeding volume of 1 to 1.5 kg / mu, density of 20,000 per mu is appropriate. Feeding value: Sweet sorghum stalks have high sugar content, calcium, phosphorus and potassium are higher than corn, and are more easily absorbed by cows and beef cattle. Post-planting management and castration: weeding and shoveling in the seedling stage. After each harvest, timely irrigation, weeding and topdressing should be performed. Generally sowing 30 to 40 days, plant height up to 1 to 1.5 meters, plant height 1.2 to 1.5 meters can be castrated use, leaving the sturgeon height of 15 to 20 cm. The yield of sweet sorghum fresh grass for feeding was 15,000 to 20,000 kilograms per mu, but the quality of grass varied greatly with the harvest time, and the harvest time should be grasped. 2. Sudan grass Planting time: Spring sowing in late April to early May, when the ground temperature stabilizes at 20 °C. Land consolidation: Sudan grass is a hi fertilizer crop. Organic fertilizer is used as a base fertilizer before plowing. The amount is 1,000 to 1,500 kilograms per acre and the combined farmland is turned into soil. The plough depth is not less than 25 cm, and the ploughing is completed. Planting methods: Generally used drill, 30 cm spacing is appropriate; acres per acreage of 2 to 2.5 kg; sowing depth of 3 to 4 cm. Feeding value: Sudan grass is rich in nutrients, suitable for proper cutting and good palatability, and high digestibility of cows and beef cattle. Post-planting management and castration: Sudan grass is not tolerant to weeds, and should be cultivated and weeded in time after emergence. Every ten to fifteen days, cultivating and weeding should be performed once. After each cutting, nitrogen fertilizer should be applied once, and urea can be applied to Mushi. 10 kilograms; Sudan grass needs a large amount of water, timely irrigation in case of drought, soaking until soaking, do not accumulate water. When the height of a Sudan grass plant reaches 50 to 60 cm, harvesting can begin. Generally every 30 days or so, once harvested, it can be harvested 4 to 5 times a year. The conditions of good water and fertilizer can be cut 7 to 8 times, leaving about 5 centimeters to produce fresh grass 8000 to 10,000 kilograms. 3. King bamboo grass Planting time: The spring planting time is from late March to early April, and the ground temperature reaches 15°C or more. When the temperature is low, the plastic shed can be covered with plastic film insulation. Stem treatment: King bamboo grass is vegetative pasture, the selection of mature stem section seedlings. The stems are generally mature and pest-free plants over 6 months old. The leaves that enclose the axillary buds are torn off and cut into small pieces with a knife. The cutting surface of the knife edge is beveled. Each section retains one stem section and each stem section. There should be an axillary bud, leaving the upper part of the eye short and the lower part long, and the cut stems can be planted directly. In order to improve the survival rate of seedlings, ABT rooting powder can also be used to soak for 28 hours at 100ppm, soaked with plant ash at the incision or soaked in 20% lime water for 30 minutes, and then transplanted after antiseptic treatment. Land consolidation: The land should be well-watered and well-illuminated, and plowed before planting to remove weeds, stones, etc.; loosely crush the soil, apply 3000 kg of fertilizer or 100 kg of compound fertilizer per mu. Sandy soil or hillside land should be earthworms to facilitate irrigation. The steep slopes should be planted along the contour lines and open holes in order to maintain the water and soil. The flat clay land and the low-lying land of the floodplain should be ridged and ridged to facilitate drainage. . Planting methods: The main method is to plant the stems and plant the stems. Place the prepared stems and buds upside-down and insert them into the soil at a 45-degree angle to the ground. The stem sections will be immersed in 3 cm soil, with 2000-3000 strains per mu and 35-40 cm spacing. The spacing is 50-60 cm. After planting, the axillary buds are covered with fine soil, and once a time, a clearing water or a clear water is poured. Feeding value: The fresh leaves of King bamboo grass are soft and juicy, with good palatability, rich nutrition, and high digestibility. Post-planting management and castration: After the planting of King bamboo grass, the soil is kept moist, and the emergence of seedlings is started in about 7 to 10 days, and the soil layers around the stems are loosened in time. The early growth of Pennisetum grass is relatively slow, and it should be carried out 1 to 2 times of cultivating and weeding before planting ridges, and the first cultivating and weeding should be carried out after planting for 1 month; the second weeding is carried out 2 months after planting. Emperor bamboo grass hi water, combined with irrigation timely fertilizer, in order to prompt the plant early delivery, more childbirth. When the plant grows to about 60 cm, organic fertilizer or compound fertilizer should be applied once. King bamboo grass generally can be harvested from May to November, and harvested once every 20-30 days. When used to feed cows and beef cattle, it can be harvested at a plant height of 130 to 170 cm and can be cut 5 to 6 times a year. Harvesting to 15 cm from the ground is appropriate for each stalk. Too low will affect plant regeneration. The annual mu output is between 25,000 and 30,000 kilograms.
