摘要
研究了不同施肥水平和滴灌对西瓜产量和品质的影响。施肥处理分别为推荐用量(RD)的75%、100%和125%。灌溉处理蒸散速率为0.6和0.8。一种对照是地表灌溉和常规土壤施肥。施肥和灌溉水平对植株1号果实数量和产量有显著影响。总产量在100% RD (91.1 t ha-1)时最高，而125% RD (80.13 t ha-1)时最高。100% RD施肥记录的果实数量最高，与125% RD相当。灌溉水平从0.6 ET增加到0.8 ET，植株-1的果实数量和果实产量都有所增加。100% RD施肥记录的植株-1产量最高，为8.51 kg。施肥和灌溉水平对果实重没有影响。亏缺灌量为0.6 ET时，TSS、番茄红素、抗坏血酸和糖含量均未增加。
Effect of fertigation and drip irrigation on yield and quality of watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai]
The study was conducted to evaluate the influence of different levels of fertigation and drip irrigation on yield and quality of watermelon. Fertigation treatments were 75, 100 and 125 % recommended dose of fertilizer (RD). Irrigation treatments were 0.6 and 0.8 evapotranspiration (ET) rates. One control was taken with surface irrigation and conventional soil application of fertilizers. Levels of fertigation and irrigation exerted significant influence on number of fruits plant-1 and yield plant-1. Total yield was highest at 100 % RD (91.1 t ha-1) compared to 125 % RD (80.13 t ha-1). Fertigation at 100 % RD recorded highest number of fruits which was on par with 125 % RD. There was increase in number of fruits plant-1 and fruit yield with increase in irrigation level from 0.6 to 0.8 ET. Fertigation at 100 % RD recorded the highest yield of 8.51 kg plant-1. Fertigation and irrigation levels had no influence on fruit weight. TSS, lycopene, ascorbic acid and sugar contents did not increase with deficit irrigation of 0.6 ET.
