中文摘要	在西北干旱半干旱地区,设置3个水分水平和3个氮素水平,共9个处理,应用完全随机区组试验设计,研究不同水氮处理组合对温室甜瓜氮素吸收分配、产量及土壤硝态氮分布和累积的影响。试验结果表明:甜瓜成熟期地上部干物质量以及氮素累积量以中水中氮(W_2N_2)处理为最大,甜瓜采收后各处理硝态氮含量在0~15 cm土层内最高,随土层的加深硝态氮含量逐渐减小。0~60 cm土层内硝态氮累积量随施氮量的增加而增大,随灌水量的增加而减小。甜瓜产量随灌水量和施氮量的增加而提高,但是在高水和高氮条件下略有下降。滴灌施肥的施氮量和灌水量控制在N_2 (130 kg/hm~2)和W_2(1.0ET_c)时,有利于提高甜瓜产量,是试验地区膜下滴灌条件下温室甜瓜生产中适宜的水氮组合。
英文摘要	A greenhouse muskmelon variety was grown under mulched drip irrigation to investigate the effects of different water and nitrogen levels on nitrogen nutrient absorption, distribution and yield of greenhouse muskmelon, soil NO_3~--N distribution and accumulation, which can provide theoretical basis for high water-fertilizer use efficiency and the optimal regulation and control of greenhouse muskmelon. Muskmelon plants were subjected to three irrigation levels and three nitrogen levels, and totally were 9 treatments. Treatments were completely arranged according to randomization. Results showed that the above-ground dry matter accumulation and amounts of N accumulation were obtained in the treatment of W_2N_2 and the content of soil NO_3~--N was the highest in 0~15 cm soil layer after the muskmelon harvest and the content of soil NO_3~--N decreased with the increase of soil depth. The accumulation of 0~60 cm soil NO_3~--N increased with the increase of nitrogen rate and decreased with the increase of irrigation amount. The yield of muskmelon increased with the increase of irrigation amount and nitrogen rate except for the treatment of W_3 and N_3. It was concluded that the irrigation level W_2 and nitrogen level N_2 could be recommended as the best combination of water and nitrogen which can improve muskmelon yield in the production of muskmelon under drip irrigation with plastic film mulched in the experimental area.
