摘要

In order to improve the quality and yield of'Tingxue 1'and accelerate its popularization,the key cultivation techniques of the variety were studied.The results showed that'Tingxue 1'could be cultivated whole year in Shanghai.Its suitable plant density was 8 910 plants/hm2 with plant space of 33 cm and row space of 250 cm in spring,summer or autumn.The appropriate pre-plant fertilizer rate was 15 t/hm2 refined organic fertilizer plus 600 kg/hm2 " Shima" compound fertilizer or 300-450 kg/hm2 watermelon-special compound fertilizer.The best pruning method was double vine pruning,which was removing the growing point of main stem at 4-5 leaves stage and keeping two strong branches.Two branches' growing points should be removed at their 12th nodes in spring cultivation.%为了提高‘亭雪1号’的品质和产量,加速其推广,进行了该品种的配套栽培关键技术研究.结果表明:‘亭雪1号’在上海地区可以周年栽培,种植密度以株距33 cm、行距250 cm(8 910株/hm2)为佳;基肥施用量以精制有机肥15 t/hm2+狮马牌复合肥600 kg/hm2或西瓜专用复合肥300-450 kg/hm2为宜;最佳整枝留果方式为双蔓整枝,即在主蔓4-5片叶时摘心,选留2根粗壮子蔓生长,并在第12节打顶.
