摘要
木瓜网室栽培是目前防止木瓜轮点毒素病最有效的方法。广东雷州半岛气温较高,网室因日照通风不良,且温度高于网外,导致植株易徒长、茎细、结果部位高。为探讨网室木瓜倒株栽培利弊,评估找出倒株适期及最佳倒株方法,开展本项技术研究。结果表明,冬植网室木瓜倒株适期为定植后2个月平均株高39.50 cm效果最好,株高及结果部位降低约20 cm,茎增粗0.37 cm,但结果数减少34个/株,采收期延迟18.5 d,开张度、叶片数、单果质量、肉质、糖度及肉色则与对照相比无显著差异;倒株方法以用塑胶绳固定拉倒法效果最好。秋植网室木瓜倒株适期为定植后1个月平均株高36.03 cm效果最好;倒株方法利弊与冬植相同,亦以塑胶绳固定拉倒法为佳。
Cultivation of papaya in net room is the most effective method to prevent papaya toxin disease.The temperature in the Leizhou Peninsula is relatively high,the ventilation in net room is not well,and the temperature is higher than that of the net outside,which resulted in leggy plants,thin stems and high fruiting position.The purpose of this study is to explore the advantages and disadvantages of the inverted planting of papaya in the net room,and to evaluate and find out the suitable period and the best method for inverted planting.The optimum period for the inverted planting of papaya in net room in winter is 39.50 cm on average plant height after two months of planting.There was no significant difference in opening degree,number of leaves,fruit weight,flesh quality,sugar content and flesh color after 18.5 days delay.The optimum period for the inverted planting of papaya in the net room in autumn planting is 36.03 cm on average plant height after one month of the planting.
