摘　　要：观察温室甜椒在每平方米８ 个茎枝条件下，３ 种不同整枝方式对其干物质生产分配规律及对产量波动的影响，结果表明：甜椒单干整枝（Ｔ１） 比不同双干整枝（ 两枝留果与一枝留果） 的叶面指数、单位面积生物量和产量显著增高，单位面积果实中干物质分配比例也明显提高。双干整枝双枝留果处理（Ｔ２） 与单干整枝干物质分配规律基本相同，而双干整枝若限制一枝坐果（Ｔ３） ，植株总干物质量不受疏去一枝花的影响，但其干物质分配到营养器官的比例相对增大，单位面积产量明显降低。不同处理对甜椒产量波动规律影响不大。Three different pruned methods for greenhouse sweet pepper were tested. Biomass production and distribution and yield fluctuation of sweet pepper were investigated. The results indicated that Leaf area index,biomass production and yield per square meter were significantly higher for T 1 (8pl·m -2 with one stem) than those for T 2 (4pl·m -2 with two stems and no flowers removed) and for T 3 (4pl·m -2 with two stems and all flowers of one stem removed). T 1 and T 2 had a same pattern for dry matter distribution. In T 3 the total dry matter production was not influenced by defloration of one of stems,but more dry matter distributed to vegetative parts. The yield (T 3) per square meter was decreased. Yielding pattern was not influenced by the treatments.
