It is a hybrid of Pennisetum americana and Purple pennisetum. With its stems and leaves to raise herbivorous fish, bait coefficient of 25-30, fish palatability is not as good as Sudan grass. Cut output of 195-300 tons / ha. Hi warm, moist, light frost resistance, but will freeze to death below 0 °C, so the Yangtze River can not naturally winter. Hybrid plants can obtain seeds. At present, it is better to use a hybrid generation for asexual reproduction. Stem segmentation and root division methods were used for planting. Breeding methods: The first step is to protect the species during winter. In the first frost, the stem was selected as a stem for the growth period of more than 100 days and was strong and solid. The stem was cut from the base of the plant and the shoot was cut off. The leaves that were hung were removed and used as spare. It is also possible to dig whole roots before stopping growth in December. The stalk part is only about 5 cm at the base and the rest are removed. There are many methods of insulation for overwintering, and the effect of membrane greenhouses is best. According to the number of conservation species, it can be made into a greenhouse or a shed. This method can both protect the species during winter and reproduce, and the seedlings of the following year can also grow early and give birth early. The specific method is to turn the land in the greenhouse well, cut the spare stem into 12-13 cm long sections, each section has a stem section, the stem section is biased to the lower end of 1/3, the upright end of the stem is inserted into the soil In the middle, the stem section is 3 - 3.5 centimeters under the soil, and the upper and lower ends cannot be reversed. If the root is overwintering, all the roots will be implanted in the soil, leaving the base stems exposed on the soil. The spacing is about 10 cm. Planting stems and seed roots should be done after implanting in soil, and then keep the greenhouse warm and moist. If it is only for winter maintenance, the storage temperature is maintained at 5-10°C. If the temperature is too high, proper ventilation is required to reduce the temperature. Overwinter conservation can also be carried out by pit burying method, digging a shallow pit in the leeward sun, placing the stems neatly, covering the soil, covering the earth about 40 centimeters thick, low temperature is thicker, so that the pit temperature is maintained at about 7 degrees Celsius . The second step is transplanting. In early May, the temperature can be transplanted when the temperature reaches around 15°C. Turn over the land first and apply basal fertilizer. If the rooting method is used, the roots will be cut through the winter, so that each root has 1-2 buds. Do not cut the bud. The method of planting people in the field can refer to the above-mentioned wintering method, but the spacing of the plants is about 40-45 cm. The stem segments of long-emerged shoots in the greenhouse can be transplanted directly along the above row spacing. Using the pit-burial method to overwinter, the stems are cut into sections according to the method of overwintering stem sections introduced earlier. The stem segments with prominent stem segments and buds were selected, and the higher the survival rate was, the lower the old stem segments were. Insert the selected stem section upright into the soil and cover about 6 cm of soil on the stem section. The spacing is the same as above. Spray water after transplanting. The Yangtze River valley began to castrate in early June and the cutting height is preferably 80-100 cm. In June and July, the growth was fastest, and the water and fertilizer were suitable. Every 10-15 days, it can be cut once. May 8-10 cuts 8-10 times. In October, when the temperature dropped below 20°C, the growth slowed down, and in mid-December and later, it stopped growing.
The above four grasses produce high yields and require high fertilizers. Must be enough base fertilizer, base fertilizer mainly organic fertilizer, such as the use of manure, applied per hectare 10500-15000 kg, or 600 tons of fresh mud (thickness of about 3 cm). The phosphorus-deficient soil is applied with about 225-300 kg of superphosphate per hectare and ploughed into the soil with organic fertilizer. During the cutting period, the top dressing is applied once every 1-2 times, with diluted livestock and urine and pond mud, with little or no fertilizer. The authors found that chemical fertilizers cause a reduction in the disease resistance of Sudanese grasses. For example, it is recommended that ammonium sulfate should be applied at a rate of about 225 kg per hectare for combined application of fertilisers. The four grasses grow vigorously with less weeds, but they also require cultivating and weeding. After one or two times of cutting, cultivating once, while rooting. If covered with mud as base fertilizer, weeds are generally free of weeds and no cultivators are required. Irrigation during drought, especially Sudan grass, grassy grass and hybrid pennisetum. There are few pests and diseases of the four species of grass. In case of drought, poor irrigation or lack of fertilizer, there are occasional serious diseases and insect pests. Low-toxicity and low-residue drugs should be used according to the pests and diseases. After half an month of application, or after rain, castration should be avoided to avoid poisonous fish. .
