摘芯程度对黔辣3号主要经济性状的影响

Effect of Tip Pruning Degree on Main Economic Characters of Qianla 3,a New Pepper Variety

为辣椒新品种黔椒3号的推广以及摘芯技术在辣椒生产上的应用提供参考,进行了黔辣3号现蕾期不同摘芯程度对主要经济性状的影响试验。结果表明:摘芯后植株矮、茎较粗、侧枝多、单株挂果数多、成熟一致,生长期缩短。在现蕾期摘去2叶1～2芯的干椒产量为276.86kg/667m2,比对照(不摘芯)增产50.51%;千粒重最重,为6.72g。

Qianla 3, a new pepper variety, was tested to study the effect of tip pruning degree at budding stage on its main economic characters to provide a reference for popularization of Qianla 3 and application of tip pruning technique in pepper production. The results showed that performance of the pepper plants after tip pruning at budding stage was dwarf, strong stem, more lateral branches, more peppers,early maturity and maturity uniformity. The dry pepper yield of Qianla 3 with removing two leaves and 1~2 leaf buds on the plant tip at budding stage could reached 276.86kg/667m2 ,50.51% higher than CK and its 1000-seed weight was up to 6.72 g.
