不同水肥处理对设施西瓜的形态指标及产量的影响

Effects of Different Water and Fertilizer Treatments on Morphological Indexes and Yield of Protected-land Watermelon

在陕西宝鸡地区引入礼品西瓜新品种苏梦8号,通过在大棚中小区试验,研究苏梦8号在不同水肥处理下的形态指标、产量及节水节肥效果,设计了常规水肥处理和滴灌水肥处理。结果发现滴灌处理的西瓜在不同时期长势更好,产量较高,增产率达6%,水分利用效率提升了19%,节省肥料总量36.5%。

‘Sumeng 8’,a new gift watermelon variety,was introduced into Baoji area.The morphological index,yield,water-saving and fertilizer-saving of‘Sumeng 8’under different water and fertilizer treatments were studied through plot experiment in the greenhouse.The conventional water and fertilizer treatments and drip irrigation water and fertilizer treatments were set up.The results showed that the watermelons treated with drip irrigation grew better in different periods,its yield was increased by 6%,water use efficiency was increased by 19%and 36.5%of total fertilizer was saved.
