| 摘 要： | 研究了不同施氮水平对厚皮甜瓜生长发育、产量及品质的影响。结果表明,厚皮甜瓜株高,叶面积增长速度随施氮量的增加而增加,主蔓茎粗、植株干物质在施N 116.25 kg/hm2下增长最快;施N量在116.25kg/hm2下果实Vc,总糖含量最高,施N量在116.25~232.50 kg/hm2范围内,对可溶性固形物含量影响不大;产量随施氮量增加呈先升高后下降趋势,施N 116.25 kg/hm2产量最高,达到43 273.35 kg/hm2,但继续增施N到465 kg/hm2,产量反而显著低于不施氮的空白对照。

| Abstract: | This experiment was carried out to investigate effects of different levels of nitrogen application on growth,yield and quality of muskmelon.The results showed that increasing speed of height and leaf area of muskmelon went up with the increase of nitrogen level.The increasing speed of stem diameter and total dry matter were the fastest in 116.25 kg/hm2 N application.The content of Vc and soluble total sugar were the highest in 116.25 kg/hm2 N application,there were little effects on the content of soluble s... |
