中文摘要	本文为探明宁夏南部半干旱雨养农业区不同膜色地膜覆盖对旱作区马铃薯生长代谢、抗性生理、光合特性以及增产增效的影响。在2016和2017年以马铃薯青薯9号'为试验材料,设置黑色地膜覆盖(BM)、白色地膜覆盖(WM)和对照无膜覆盖(CK)三种覆盖措施,探究不同处理下马铃薯植株株高、冠幅、功能叶片光合特性、丙二醛含量、细胞膜透性、根系活力以及干物质积累的动态变化和产量及构成。结果表明,BM能显著促进马铃薯植株的生长、提升产量。相较于CK和WM,BM处理下马铃薯叶片的净光合速率、株高、冠幅和根系活力显著提高,蒸腾速率、丙二醛含量和细胞膜透性明显降低。除此之外,覆膜提升了各器官的干物质量积累量,从而显著增加马铃薯产量及产量构成。综合2年结果来看,BM处理的马铃薯具有较高干物质积累量和产量,产量分别较WM和CK显著增加17.85%和60.52%。相关性分析表明,除蒸腾速率、丙二醛含量以及细胞膜透性与产量存在负相关性以外,其他指标均与产量呈正相关,且与根系活力间的相关性最显著。可见,覆膜措施能有效促进马铃薯生长代谢,缓解干旱对马铃薯的生理限制,且黑膜覆盖措施增产增效更佳,因此黑膜覆盖技术的应用与推广对该区马铃薯高效栽培具有重要价值。
英文摘要	The purpose of this paper was to investigate the effects of different colors of mulch on growth metabolism,resistance physiology,photosynthetic characteristics and yield and efficiency of potato in the semi-arid rainfed agricultural area of southern Ningxia.In this paper,we set up black film mulching (BM),white film mulching (WM) and control mulching (CK) in 2016 and 2017 with Qingshu No.9' as the experimental material.We investigated the dynamic changes in plant height and crown width,photosynthetic characteristics of functional leaves,malondialdehyde content,cell membrane permeability,root vigor and dry matter accumulation,and yield and composition of potato plants under different treatments with three mulching measures,namely,black mulch (BM),white mulch (WM) and no mulch (CK).The results showed that BM could significantly promote the growth and yield of potato plants.The net photosynthetic rate,plant height,crown width and root vigor of potato leaves were significantly higher and transpiration rate,malondialdehyde content and cell membrane permeability were significantly lower under BM treatment compared to CK and WM.In addition,mulching enhanced dry matter accumulation in all organs,which significantly increased potato yield and yield components.Based on the results of the two years,potatoes under BM treatment had higher dry matter accumulation and yield,with a significant increase of 17.85% and 60.52% in yield compared to WM and CK,respectively.Correlation analysis showed that all indicators were positively correlated with yield,except transpiration rate,malondialdehyde content and cell membrane permeability,which were negatively correlated with yield,and the most significant correlation was with root vigor.It can be seen that the mulching measures can effectively promote potato growth and metabolism,alleviate the physiological constraints of drought on potato,and the black film mulching measures increase yield and efficiency,so the application and promotion of black film mulching technology is greatly valuable to the efficient cultivation of potato in this region.
