| 1 | Effects of combined drip irrigation and sub-surface pipe drainage on water and salt transport of saline-alkali soil in Xinjiang, China显示文摘Developing effective irrigation and drainage strategies to improve the quality of saline-alkali soil is vital for enhancing agricultural production and increasing economic returns. In this study, we explored how irrigation and drainage modes (flood irrigation, drip irrigation, and sub-surface pipe drainage under drip irrigation) improve the saline-alkali soil in Xinjiang, China. We aimed to study the transport characteristics of soil water and salt under different irrigation and drainage modes, and analyze the effects of the combination of irrigation and drainage on soil salt leaching, as well as its impacts on the growth of oil sunflower. Our results show that sub-surface pipe drainage under drip irrigation significantly reduced the soil salt content and soil water content at the 0–200 cm soil depth. Under sub-surface pipe drainage combined with drip irrigation, the mean soil salt content was reduced to below 10 g/kg after the second irrigation, and the soil salt content decreased as sub-surface pipe distance decreased. The mean soil salt content of flood irrigation exceeded 25 g/kg, and the mean soil desalination efficiency was 3.28%, which was lower than that of drip irrigation. The mean soil desalination rate under drip irrigation and sub-surface pipe drainage under drip irrigation was 19.30% and 58.12%, respectively. After sub-surface drainage regulation under drip irrigation, the germination percentage of oil sunflower seedlings was increased to more than 50%, which further confirmed that combined drip irrigation and sub-surface pipe drainage is very effective in improving the quality of saline-alkali soil and increasing the productivity of agricultural crops. | HENG Tong LIAO Renkuan WANG Zhenhua WU Wenyong LI Wenhao ZHANG Jinzhu | 2018 | Journal of Arid Land2018，10，6： | 12 |

| 7 | Current-Induced Light Emission from a Laterally Anodizing Porous Silicon Device显示文摘We report the current-induced light emission(CILE)at RT from a porous silicon(PS)Schottky device exhibiting good rectifying characteristics with the ideal factor of 14.The photoluminescence spectrum from the PS layer fabricate by laterally anodization peaks at 668 nm.The intensity of CILE increases with increasing current.It has run for more than two hours and still keeps stable.Possible mechanism of CILE is discussed. | SHI Hongtao ZHENG Youdou WAND Yongbin YUAN Renkuan | 1992 | Chinese Physics Letters1992，9，10： | 0 |
| 8 | Phonon Participation in the Light Emission Process of Porous GeSi Layer显示文摘Relaxed Ge_(0.5)Si_(0.5)/Si heterostructure was grown by the rapid radiant heating,very low pressure chemical vapor deposition(RRH-VLP/CVD).We report the anomalous temperature dependence of photoluminescence(PL)from porous GeSi layer at 77-300K.The peak-emission energy of PL spectra from porous GeSi layer decreases with increasing temperature while its peak intensity rises,which is quite different from the temperature dependence of porous Si layer.Such dependencies are reversible and independent of temperature-change directions.No obvious 480cm^(-1) peak was observed in Raman spectrum,indicating that no substantial amorphous phase contributes the intense light emission from the porous materials.We attribute such anomalous behavior of porous GeSi layer to phonon participation in the light-emission process of porous GeSi layer. | SHI Hongtao ZHENG Youdou YUAN Renkuan | 1993 | Chinese Physics Letters1993，10，5： | 0 |
