在长江中下游地区,辣椒长季节栽培的关键技术之一是越夏整枝。为了研究不同整枝方式对越夏栽培辣椒生长的影响,试验设计了3种整枝处理,即处理1(再生整枝)、处理2(四干整枝)和处理3(多干整枝),以不整枝为对照(CK)。结果表明,采取多干整枝法最有利于辣椒的越夏生长,能使植株保持获得高产的良好株型,可有效减轻病毒病的为害,提高辣椒果实的商品性,椒果产量和经济效益分别比对照处理增加15.8%和19.0%。
In the middle and lower reaches of the Yangtze River, pepper growing season is one of the key technologies of summer pruning. In order to study the effect of different pruning methods on perennial cultivation of pepper, we designed three kinds of pruning treatments, namely treatment 1 (regenerative pruning), treatment 2 (four stem pruning) and treatment 3 (multi-pruning) Control (CK). The results showed that adopting the multi-stem pruning method was most beneficial to the perennial growth of peppers, and the plants could maintain a good plant type with high yield, which could effectively reduce the damage of virus diseases and improve the commerciality of peppers. The output and the economic benefits of peppers 15.8% and 19.0% more than the control treatment.
