文章探讨了整枝方式对厚皮甜瓜产值的影响,确定了适宜的整枝方式,为制定厚皮甜瓜高效栽培技术规范提供依据.在陕西关中地区早春大棚4膜覆盖爬蔓栽培条件下,研究3种不同的整枝方式对3个参试厚皮甜瓜品种产量、价格的影响,进而研究其对产值的影响.结果表明,'骄雪六号'、'西甜4号'、'骄雪八号'3个厚皮甜瓜品种均采用单蔓整枝产值最高,分别为19.6万、20.3万、20.9万元/hm2,与双蔓整枝(15.0万、15.55万、16.05万元/hm2)、三蔓整枝(10.35万、11.1万、12.6万元/hm2)相比均达到显著差异水平.因此,陕西关中地区早春大棚4膜覆盖爬蔓栽培条件下,3个参试品种厚皮甜瓜的整枝方式以单蔓整枝为宜.%In this paper,the effects of pruning methods on thick-skinned melon output value are discussed,the pruning method suitable for thick-skinned melon is determined, to provide a basis for the development of efficient cultivation techniques.In early spring greenhouse having 4-layer plastic film covering at Guanzhong area of Shaanxi,three thick-skinned melon cultivars,'Jiaoxue 6','Xitian 4''Jiaoxue 8'were treated with three different pruning methods,to explore the effects of pruning methods on yield,price and output value.The results showed that,compared with the output value of double-vines pruning(150000,155500,160500 yuan/hm2) and three-vines pruning (103500, 111000, 126000 yuan/hm2), the output value of all three melon cultivars reached the highest by single vine pruning (196000, 203000, 209000 yuan/hm2). The difference of output value among three cultivars reached significant difference level.Therefore,in early spring greenhouse having 4-layer plastic film covering at Guanzhong area of Shaanxi,the suitable pruning method for the three thick-skinned melon cultivars is single vine pruning.
