| 摘 要： | 为了探讨多效唑施用量和施用时期对辣椒生长及产量的影响,对遵椒2号进行了多效唑施用试验.结果表明,在4叶期和初花期各施用1次及初花期施用1次不同浓度多效唑,辣椒苗均表现叶色变深,株高降低,绿叶片增多,根茎增粗,苗壮;田间株高降低,第1节高变矮,根茎变粗.单株挂果数增加,单果变重,千粒重增大;增产2%～20.14%,施药与不施药对辣椒产量均有明显影响,但与施药次数差异不明显,处理浓度以250mg/kg效果最好;辣椒抗倒伏性强.施用浓度以250mg/kg效果最佳.在辣椒4叶期和初花期各施多效唑1次与初花期仅施多效唑1次相差不大.

| Abstract: | Zunjiao 2,a hot pepper variety,was applied by paclobutrazol with different concentrations and times to discuss the effects on its growth and yield.The results showed that applying paclobutrazol at four-leaf stage and first flower stage once could deepen leaf color,reduce plant height,improve lodging resistance,raise number of green leaf and stem diameter,increase pepper fruits per plant,single fruit weight and 1000-seed weight and its increase range of yield was from 2% to 20.14%.There was significant diffe... |
