摘要
连续2年对苎麻饲料专用品种"中饲苎1号"进行不同收割次数田间试验,试验设年收4次(hpy4)、5次(hpy5)、6次(hpy6)3组处理,每组3个重复,小区面积10.8 m2,研究不同收割次数对"中饲苎1号"生物量的积累与茎叶粗蛋白含量的影响。结果表明:随着年收割次数的增加,"中饲苎1号"平均鲜重产量与粗蛋白含量均呈增加趋势,但综合考虑含水量、干物质量及粗蛋白总产量等,年收割5次处理组在综合产量和饲料品质上占优。
Through two-years continuous cutting of feed ramie“Zhongsizhu No.1”by different harvesting times per year(hpy4,hpy5,hpy6)during growing season in Changsha,the biomass accumulation and crude protein content among treatments of“Zhongsizhu No.1”were tested and compared for two years.The results showed that the fresh weight and average crude protein content increased gradually with the increasing number of cutting,while considering the water content,yield of biomass and total crude protein production,it was suggested that the best harvesting times for“Zhongsizhu No.1”in Changsha area were 5 times all year with high yields of biomass and crude protein.
