摘　　要：研究采用田间随机区组试验,通过对撑绿竹不同施肥时期处理的立竹数、胸径和秆材产量进行比较,寻求撑绿竹最佳的施肥时期。结果表明：与处理5（3、8、12月三次/a）的2007-2009年累计产量（25523.5.kg/hm^2）相比,处理4（3、8月两次/a）、处理1（3月一次/a）、处理2（8月一次/a）和处理3（12月一次/a）的累计产量依次降低了7.3%、27.7%、30.8%和34.9%。一年施用3次处理能够显著增加撑绿竹的立竹数和产量,其次是一年施用2次,一年施用1次对立竹数和产量的增加效应较低。一年施用1次的时候,在3月施用效果要比8月和12月的要好。不同施肥时期处理对撑绿竹胸径的影响与立竹数和产量的基本一致。在生产实际中,考虑到劳力和费用问题,可以在3月和8月各追肥1次。In order to determine the best fertilizer period,the study used a randomized block field trial and compared the culm numbers per clump,diameter at breast height（DBH） and yields of different fertilization period treatments through a randomized block field trials.The results showed that the cumulative yield between 2007 and 2009 of the treatment of fertilization 3 times a year in March,August,December reached 25522.3 kg/ha.Compared with fertilization 3 times a year,the cumulative yields of the treatments of fertilization 2 times a year in March,August,fertilization 1 times a year in March,in August and in December decreased by 7.3%,27.7%,30.8% and 34.9%.The effects of application fertilizer for 3 times a year on culm number per clump and yield of the bamboo were the best,followed by application fertilizer 2 times a year,which of 1 times a year was the lowest.Application fertilizer in March was better than in August and in December when application fertilizer 1 times a year.The effects of different fertilization period treatments on DBH of bamboo were basically consistent to those of the culm numbers per clump and yields.Taking into account the labor and costs,application fertilizer for 2 times a year in March and August can be used in actual production.
