西瓜新品种‘申蜜968’的优质高产栽培技术研究

Study on the cultivation techniques for good-quality and high-yield of new watermelon cultivar ‘Shenmi 968’

‘申蜜968’是上海市农业科学院设施园艺研究所最新育成的高品质抗枯萎病西瓜新品种,为了加速该品种在生产上的推广应用,开展了配套栽培关键技术的研究。结果表明:‘申蜜968’在上海地区春播早熟设施栽培最适播种育苗期为2月10-20日,采用双蔓整枝方式,选留主蔓第15-18节位上的第2或第3雌花坐果为佳;定植前大田撒施270 kg∕hm^2狮马牌复合肥(N∶P∶K=15%∶15%∶15%)+15 t∕hm^2充分腐熟的有机肥,一次性耕翻做底肥;膨瓜期随水滴施狮马牌复合肥300 kg∕hm^2,同时每5-7 d叶面喷施一次狮马牌高钾叶面肥(N∶P∶K=7%∶12%∶40%),每次5 kg∕hm^2,连续喷施3次,可有效提高该品种的品质和产量。

In order to improve the quality and yield of new watermelon cultivar’Shenmi 968’,which is resistant to Fusarium wilt,and accelerate its application in production,a series of key cultivation techniques were studied.The results showed that the optimum sowing date of’Shenmi 968’was February 10-20.The two-vine pruning was the most suitable pruning pattern for the cultivar,the best fruit setting place was 15-18 node on the major vine.Before planting,15 t/hm^2 organic fertilizer+270 kg/hm^2 Shima Brand complex fertilizer(N:P:K=15%:15%:15%)should be applied.During the fruit expansion period,the compound fertilizer 300 kg/hm^2 should be applied with drip irrigation.At the same time,Shima Brand high potassium fertilizer(N:P:K=7%:12%:40%)should be sprayed every 5-7 d,5 kg/hm^2 each time for 3 times of continuous spraying.The above measures were conducive to the increase of yield and quality of the cultivar.
