摘　　要：为提高瓠瓜品种浙蒲6号和浙蒲9号的制种产量,通过不同双亲播期、种植密度和坐果节位的试验,探究了其对瓠瓜制种产量的影响。结果表明,浙蒲6号瓠瓜制种时母本不宜比父本迟播,母本可适当密植,株距选择40 cm为最佳;浙蒲9号瓠瓜制种时母本比父本早播10 d,母本株距选择40 cm,坐果节位选择低节位(子蔓7~8节)时,制种产量能得到显著提高。In order to improve the seed yield of bottle gourd varieties(Zhepu 6 and Zhepu 9),the effects of different parent sowing dates,planting density and fruiting node position on seed yield were explored.The results showed that the female parent should not be sown later than the male parent during seed production of Zhepu 6,and the female parent should be planted close together,and the best distance between plants was 40 cm.The female parent of Zhepu 9 gourd should be sowed 10 days earlier than the male parent,and the planting density should be 40 cm,the fruiting node position should be a low node(7-8 nodes of the subvine).After implementing these cultural practices,the yield of seed production can be significantly improved.
