摘要
为探究不同整枝方式对设施栽培丝瓜熟性和产量的影响,以有棱丝瓜和普通丝瓜为材料,进行整枝处理,分析不同整枝方式对丝瓜产量相关主要农艺性状的影响。结果表明,有棱丝瓜秋茬设施栽培提前整枝处理不能使开花提前或单瓜质量提高,但可使第1雌花着生节位显著下降,从而有利于获得较高的早期产量,且6叶1心时摘心留4条一级侧枝获得的产量最高;春季设施栽培于5叶1心时摘心留3条一级侧枝处理有利于有棱丝瓜获得高产。普通丝瓜秋茬设施栽培过早进行摘心留侧蔓整枝处理会推迟第1雌花开放从而影响早期产量;而早春设施栽培通过整枝可使第1雌花节位降低5~7节,但过早或过迟整枝反而延迟了第1雌花开放;5叶1心至7叶1心摘心留蔓可使普通丝瓜的第1雌花开放提早7~10 d,并有利于提高产量。
In order to explore the effects of different pruning methods on the maturity and yield of luffa under facility cultivation,Luffa acutangula Roxb.and L.cylindrica Roem.were used as materials to carry out pruning treatment,and the effects of different pruning methods on the main agronomic characteristics related to yield were analyzed.The results showed that early pruning treatment on L.acutangula Roxb.in autumn could not advance flowering or increase the single fruit weight,but could significantly reduce the first female flower node,which was beneficial to obtain higher early yield,and the highest yield was obtained by picking the center and leaving 4 primary lateral branches at the time of 6 leaves and 1 center.In spring,it was beneficial to obtain higher yield by picking the center and leaving 3 primary lateral branches at the time of 5 leaves and 1 center.Early pruning treatment on L.cylindrica Roem.in autumn would delay the first femaleflowering time and affect the early yield.In early spring,pruning treatment could reduce the first female flower node by 5-7 nodes,but pruning too early or too late would delay the first female flowering time.The first female flowering time was 7-10 days earlier and the yield could be increased by picking the center and leaving lateral branches during the time of 5 leaves and 1 center to 7 leaves and 1 center.
