摘要
采用盆栽试验方法,研究了不同上限灌溉处理对辣椒生长形态、生理变化及各产量指标的影响。结果表明:随着辣椒生育期内灌水量的增加,辣椒的株增高、茎增粗、光合速率及蒸腾速率提高。在幼苗期,灌水量大小对辣椒生长发育影响不明显;在现蕾期、开花结果前期,灌水量为田间持水量的80%时辣椒生长比较好,但在盛收期灌水量为田间持水量的70%时有利于节水、增产。
Based on pot experiment,it studies the effects of different optimum irrigation on hot pepper growth,physiological and various products indexes.The results show that the plant height,stem diameter,net photosynthesis rate,transpiration rate are all increased along with the increase of irrigation quantity.At the seeding stage,the effect of different irrigation quantity on plant growth is not significant.At squaring,bloom and fruit-bearing stages,80% irrigation of soil moisture capacity is better for plant grow...
