| Research forages'fresh yield, nutritional quality and Agronomic traits (Guimu—1 Hybrid Pennisetum urpureu and Pennisetum purputeum cv.mott) under different harvest time in the Hunan region, promoting research and providing some scientific basis for two forages in Hunan. Have repeated three times to Guimu—1 Hybrid Pennisetum urpureu and Pennisetum purputeum cv.mott, a total of six residential, residential area is 6×5= 30m2, combined with soil preparation before planting wet manure per 5000 kg 667m2 facilities for basic fertilizer, after transplanting the forages poured the colonization water one time. During the cultivation, weeding and jointing a dilute water one time (30 kg/667m2). The results showed that:l.With the harvest time goes, Guimu—1 Hybrid Pennisetum urpureu and Pennisetum purputeum cv.mott' expanding leaves of chlorophyll a, chlorophyll b and total chlorophyll contents overall in uptrend, while carotene content in decreased.2. Guimu—1 Hybrid Pennisetum urpureu's ADF content in the whole harvest time remains unchanged, while the Pennisetum purputeum cv.mott in the first time increased and then is basically decreased.3. Guimu—1 Hybrid Pennisetum urpureu appeared the maximum tiller number in September. The stems and leaves of two forges showed an upward trend with the harvest time goes, but they have different upward trend.4. With the harvest time goes, Guimu—1 Hybrid Pennisetum urpureu and Pennisetum purputeum cv.mott showed an decline trend.5. Guimu—1 Hybrid Pennisetum urpureu and Pennisetum purputeum cv.mott' ground fresh (dry) weight showed an upward trend with the harvest time goes, but they have differences, the maximum biomass of they occurred at different times, Guimu—1 Hybrid Pennisetum urpureu appeared early (in August) than Pennisetum purputeum cv.mott (in September).6. Guimu—1 Hybrid Pennisetum urpureu and Pennisetum purputeum cv.mott the whole DM content showed an decline trend with the harvest time goes, and the CP and the water content remains the same trend. |
