施肥对撑绿竹幼竹生长的影响

在赤水市和仁怀市对撑绿竹不同施肥量对幼竹生长的影响进行了试验研究,施肥量设置0.3 kg/丛、0.4 kg/丛、0.5 kg/丛、0.6 kg/丛以及对照5种处理。试验结果显示,在赤水市和仁怀市2个试验点均表现为随着施肥量的增加新生竹胸径、竹高、质量的增幅相应增大,且以0.6 kg/丛施肥量的效果最好。不同施肥处理间,2个试验点的新竹胸径、质量差异均达极显著水平;在竹高方面,赤水试验点不同施肥处理间差异达显著水平,而在仁怀试验点差异达极显著水平。

Effect of Fertilization on the Growth of Young Bambusa pervariabilis×Dendrocalamopsis grandis

The effect of fertilization amount on the growth of young Bambusa pervariabilisxDendrocalamopsis grandis was experimented and studied in in Chishui City and Renhuai City. The fertilization amount was set as 5 treatments, i.e., 0.3, 0.4, 0.5 and 0.6 kg per clump and the control group. The experimental results showed that, in the two experiment sites in Chishui and Renhaui, the DBH, height and yield of young bamboo increased with the increased fertilization amount, while the treatment of 0.6 kg per clump produced the best effect. Between the different fertilization treatments, the DBH and yield of young bamboo in the two sites were significantly different. As for the culm height, the treatments showed significant difference in Chuishui site while extremely significant difference in Renhuai site.
