本试验从当前西瓜栽培上急需回答的最佳育苗苗龄的实际问题出发,以龙宝为试材,在小棚内设置了4月17日、4月25日、5月2日、5月8日播种,5月26日定植的39天,31天、24天、18天苗龄四个处理。田间三次重复,随机排列。调查和分析了不同苗龄的生长发育状况及不同苗龄的产量,从而得出4月17日和4月25日播种的39天和31天苗龄生长发育最早,雌花出现早,座瓜期合适,产量较高,从而得出4月25日播种31天苗龄是既经济又有效的最佳苗龄。
This experiment from the current watermelon cultivation urgently need to answer the actual seedling age of the actual problems starting to Longbao as the test material in the shed set April 17, April 25, May 2, May Planting on the 8th, May 26 planting 39 days, 31 days, 24 days, 18 days of seedling age four treatment. Field repeated three times, arranged randomly. The growth and development status of different seedling age and the yield of different seedling age were investigated and analyzed. The results showed that the 39th and 31st days of April sowed on April 17 and April 25 were the earliest growth and development, Appropriate, high yield, which concluded that April 25 planting seedling age of 31 days is both economical and effective the best seedling age.
