The grass is an intraspecific hybridization combination made with the American Pennisetum sibirica TifT23A, and Pennisetum 3B-6. It is suitable for high-yield and high-quality pasture varieties cultivated in the annual and summer seasons in the Yangtze River basin and in the south. 1. Morphological characteristics and major reproductive characteristics. The plant is about 300 cm high and has a well-developed root system. There are 11.2 births, more than 20 main leaf blades and 60-70 cm long. The seeds weighed 7.0 grams and the seeds were gray. The number of fertility days in Nanjing was 130 days and the yield was 6000-8000 kg/mu. Hi warm and humid climate conditions, when the temperature reaches 20C or more, the growth rate. Drought-resistant. Loosing, disease-free occurrence, suitable for multiple cutting, feeding herbivores and fish. 2, cultivation techniques. The seed of Pennisetum americana is small, and the young shoots have poor top soil. The quality of the soil preparation has a great influence on its seedling emergence. Therefore, the soil preparation must be fine and it is conducive to emergence. When the temperature reaches 15C, the planting is appropriate. In the middle and lower reaches of the Yangtze River, from about the end of April to the beginning of May, the Huanghuai region is sown in May-June, with a depth of about 1.5 cm. 5-6 days to emerge. Mu sowing volume 0.7-1.0 kilograms. Line spacing 50 cm: It can also be transplanted and planted, line 40*20CM. In order to prevent ants from waiting until the ground pests harm seed or seedlings, it is necessary to use pesticides such as furanide or seed dressing or toxic soil. Use 1500 kg of high-quality organic fertilizer per acre and apply 15-20 kg of calcium phosphate as base fertilizer. After each cutting, topdressing should be applied once, using 5 kg of urea per acre (or other nitrogen fertilizer, human and animal waste). 3. Nutritional value and utilization. Dry matter contained crude protein 15.4%, crude fat 4.2%, and crude fiber 35%. Nitrogen free extract 25%. The height of the coarse ash 9% when castrated: 70-80 cm for feeding fish, rabbits, geese, and pigs; 1-1.3 m for cattle and sheep. Keep the height of 10-15 cm, do not. Rainy days castrated. Otherwise it will cause lack of plants and reduce production. China Agricultural Network Editor
