摘要:
以西瓜为试材，通过不同氮钾用量试验，研究了不同肥料用量对西瓜生长发育、产量和品质的影响。结果表明：在一定范围内，随着氮用量的上升，〖JP2〗西瓜产量增加。当每667 m2氮用量达到10 kg以后，西瓜产量开始呈下降趋势；钾对提升西瓜品质有较大作用，高钾处理（每667 m2施用16 kg K2O）比低钾处理（每667 m2施用14 kg K2O）糖酸比提高4.57%~6.27%。该试验条件下每667 m2氮、钾推荐用量分别为6.73 kg和16 kg。
Abstract:
In order to offer theoretical basis for reasonable and efficient fertilization on protected watermelon in greenhouse,the effects of different nitrogen and potassium fertilizer on growth,development,yield and quality of watermelon were studied.The results showed that watermelon yield improving with the amount of the nitrogen fertilizer increasing,however,667 m2 nitrogen application over amount 10 kg decreased the yield.The increase of potassium supply could greatly increase the quality of watermelon,The sugar-acidity ratio of higher potassium supply（16 kg K2O per 667 m2） got 4.57%-6.27% more than the lower potassium supply（14 kg K2O per 667 m2）.Under the experiment condition the recommendation N and K2O fertilization were 6.73 and 16 kg per 667 m2.
