整枝方式对大棚西瓜长季节栽培抗病性和产量的影响

Effects of Different Pruning Methods on Resistance and Yield of Greenhouse Watermelon for Lengthened Growth Period

为探索不同整枝方式对西瓜长季节栽培座果节位、抗病性和产量的影响,以西瓜早佳84-24为研究对象开展相关研究。结果表明:设施条件下,采用三蔓整枝(一主蔓二侧蔓),生长最为协调,病害轻,病情指数均在5.3%以下;座果节位适中、成熟早,不易早衰;产量高,折合产量高达5 143 kg/667 m^2,最适宜长季节栽培。

In order to explore the effects of different pruning methods on the joint position of the fruit,disease resistance and yield of watermelon cultivation for lengthened growth period with the main variety of watermelon Zaojia84-24as experimental material.Under the condition of facilities,the results showed that the three vine pruning was the best methods for lengthened growth of Zaojia84-24watermelon variety with plant coordinated growth,light disease,and the fruit setting appropriate,mature early,not easy to premature aging,and high yield.
