摘  要:
本试验比较了矮柱栽培的3种密度与高柱栽培在生长和产量方面的差异及其经济效益。试验结果表明,矮柱(高1.6米)密植投产早,植后3年便有收获;产量高,收获第一年2×1.2米处理亩产鲜果2022.7公斤,产值超万元,显著高于对照。历年累计产量各处理间差异不显著。矮柱密植栽培因单位面积内的株数多,体积大,结果面广,结果枝多,形成丰产树型快,故能早产高产。3种密度中以2×1.2米处理最好,历年累计平均亩产量也稍高,其后依次为2×1米和2×1.5米处理。经分析,作为胡椒产量基础的树型结构如枝序数量、各级结果枝数量、体积和表面积(结果面)等,各处理群体间差异显著或极显著。这是因为矮柱密植栽培的群体量多弥补了个体量少的缘故。据调查,矮柱密植栽培植株生长整齐,风害轻,密度越大植株生长整齐度越高,开花期间遇台风的落花穗数量显著低于高柱栽培。

摘  要:
A comparison was made between pepper (Piper nigrum)vines on shorter supports arranged in three differant spacings and vines on tall supports arranged in conventional spacing in relation to their growth rate, yield and economic results. The former (on 1.6 m tall supports)was found to give earlier and better crop than the latter (control) and best results were obtained with spacing of 2×1.2 m, which also broughtd about a slightly higher cumulatiye mean output per unit area over years. It was observed that closely-spaced pepper vines grew uniformly on shorter supports. The higher the planting density, the more uniformly the vines grew. In addition, much less flower clusters of vines on lower supports were blown off by a typhoon during flowering in comparison with vines on higher supports.
