    摘要:

    选择硫酸钾、硝酸钾、氯化钾3种钾肥,在江苏沿海开展西瓜钾肥效果试验,研究不同钾肥类型对西瓜生长及品质的影响。结果表明,施用不同钾肥可协调西瓜生长,避免茎叶生长过旺;与对照和其他钾肥处理相比,施用硝酸钾肥显著促进根系干物质积累,硫酸钾肥则显著促进茎部干物质积累;硝酸钾肥和硫酸钾肥显著提高西瓜单果重和产量;氯化钾肥处理西瓜植株干物质积累和产量均最低,与对照无显著差异,但氯化钾肥处理有降低可滴定酸和提高Vc含量的作用。今后应从西瓜产量、品质和环境影响等多方面评价施用不同类型钾肥的综合效应。

    Abstract:

    Potassium sulfate, potassium nitrate and potassium chloride were used to study the effect of potash on the growth, yield and quality of watermelon in Jiangsu Province. The results showed that all the potash fertilizers enhanced the growth of watermelon by inhibiting the over growth of stems and leaves. Potassium nitrate addition significantly increased the root dry matter accumulation compared with control and other potash fertilizers, whereas potassium sulfate significantly increased the stem dry matter accumulation. Both potassium nitrate and sulfate significantly improved the single fruit weight and yield of watermelon. Although potassium chloride addition had the lowest dry matter accumulation and yield compared with other potash fertilizers, it declined the titratable acid content and improved the Vc content of watermelon. It is better to evaluate the synthetic effect of potash fertilizers on watermelon from the aspects of yield, quality and environmental influence.
