摘要
以‘早佳三号’为试材,在西瓜最佳施肥量的基础上,通过不同氮、钾肥运筹配比试验,研究不同时期氮、钾肥配施对西瓜生长、产量及品质的影响,探讨西瓜简约化施肥技术。结果表明,不同时期施用氮、钾肥对开花期叶片数、节位、蔓长有显著影响,但对西瓜产量、品质影响的差异不显著。因此,沿海地区采收1~2茬西瓜的早春大棚种植方式,可实行一次基施氮、钾肥,达到省工节本效果。
In order to discuss the watermelon simplified fertilization technology, the effects of nitrogen and potassium management on growth, yield and quality of watermelon were studied through different ratio of nitrogen, potassium management test, with the variety of ‘Zaojia No. 3＇used as material. The results showed that when the nitrogen and potash fertilizer were applied at different period, significant differences were observed on the leaf number, section and vine length at blooming stage, but no significant difference was found on the growth, yield and quality of watermelon. Therefore, for the sake of saving labour and cost, nitrogen and potassium fertilizer should be applied as base fertilizer in early spring greenhouse watermelon planting for early 1-2 crop harvest in coastal areas.
