摘要
研究氮肥对甜瓜干物质积累、分配以及产量和品质的定量影响是实现露地甜瓜栽培氮肥优化管理的前提。试验以自育品种新蜜杂36号为材料，定量分析不同氮肥施用水平对甜瓜干物质、产量及品质的影响，结果表明，增施氮肥显著提高甜瓜干物质积累和氮素吸收，在P20，140kg／hm2、K：0150kg／hm2的基础上施N225kg／hm2，甜瓜产量和品质均为最高，各施氮处理氮肥利用率在11％-29％之间且氮肥利用率随施氮量的增加而降低。
Quantying the effects of N fertilizer on dry-matter accumulation, distribution and yield, quality of muskmelon is the prerequisite to realize the optimal management of N fertilizer in muskmelon cultivation in open field. This experiment takes the cuhivar of muskmelon--XinMiZa36 as the experimental material, quantitatively analyzes the effect of different N fertilizer application rate on dry-matter, yield and quality of muskmelon. The results showed that increasing N fertilizer ap- plication rate could significantly raise the dry-matter accumulation and nitrogen absorption of muskmelon. The treatment of fertilizer application of N 225 kg/hm2with P2O5 140 kg/hm2 and K2O 150 kg/hm2, obtained the highest yield and quality of muskmelon. The nitrogen utilization efficiencies of all N treatments are between 11% to 29%, and the nitrogen utilization efficiency decreases with the increase of nitrogen application.
