摘  要:为了探明控释氮肥对旱地马铃薯产量效应的影响,在露地和覆膜模式下开展不同控释氮肥施用效应试验,对比分析不同种植方式下控释氮肥对马铃薯生育进程、生长指标及产量性状的影响。结果表明:不同控释氮肥通过延长马铃薯开花期至成熟期的生殖生长阶段,提高了马铃薯大中薯率、产量;其中以覆膜+控释尿素模式效果最优,马铃薯产量较常规施用化肥提高了14 740.7 kg·hm^(-2),可作为宁夏旱作区马铃薯高产栽培模式进行推广应用。In order to explore the effect of controlled-release nitrogen fertilizer on potato yield in dry land,experiments on the application effect of different controlled-release nitrogen fertilizer were carried out under open field and film mulching modes. The results showed that each treatment of controlled-release nitrogen fertilizer increased the rate and yield of large and medium-sized potato by prolonging the reproductive growth stage from flowering to maturity. Among them, treatment with film mulching and controlled-release urea was the best. Compared with conventional chemical fertilizer treatment, the yield increased by 14 740.7 kg·hm^(-2), which can be used as a high-yield cultivation model in dry farming area of Ningxia.
