| 摘 要： | 根据陇东南天水市境内7个气象站1960-2005年逐年、逐月降水、气温及日照时间资料、1980-2005年土壤湿度资料及1985-1987、2002-2004年在陇东、陇中、陇东南3地紫花苜蓿Medicago sativa等4种人工牧草的种植试验资料、天水市畜牧局调查资料,分析牧草的生长特性及对环境条件的要求.结果显示:陇东南地区最适宜人工牧草播种的时间为早秋的9月,人工牧草枝叶生长最盛时段为分枝-开花期,整株物质累计最盛的时段为结荚-收刈期.在退耕种草的过程中,应根据生产实际结合气候条件,合理安排播种时间,降低牧草种植风险,争取最大生态和经济效益. |

| Abstract: | Based on the meteorological data such as yearly,monthly precipitation,temperature,sunshine,the soil moisture of 7 weather stations in Tianshui 1960-2005,experiment data of planting alfalfa and other 4 artificial forage grasses in East,Middle,Southeast of Gansu in 1985-1987and 2002-2004,the investigation material of Tianshui Livestock Bureau,the requirements of forage grasses to environmental condition had been analyzed.The results showed that the most suitable sowing time of forage grasses was in September early in autumn,the highest period of leaves and stem accumulation was in Bifurcation-flowering period,the highest period of whole plant accumulation was in pod setting-shear period.The actual condition and climate must been considered when planting artificial forage grass,thus the risk of degree for planting could be reduced and production could be reasonably arranged,meanwhile the best ecological and the economic efficiency could be gotten. |
