| 摘 要： | 流苏树是中国二级保护植物,对其繁育技术的研究在生产实践中具有重要意义。笔者回顾了前人对流苏树繁育技术的研究,从其种子休眠、打破种子休眠,到流苏树的播种育苗、扦插繁殖、嫁接繁育以及组培快繁等方面,对流苏树繁育技术的特点进行总结与归纳,分析了不同阶段不同繁殖技术的研究进展,以期为流苏树的快速繁殖、优质大苗的培育及新品种选育提供技术参考,并从繁育技术、应用价值及古树资源的保护利用等方面对其以后的科学研究提出展望。

| Abstract: | To reveal the effects of long-term fertilization on the chestnut soil in the North Yinshan area, potato yield, nutrient absorption, water and fertilizer use efficiency were studied based on the long-term positioning experiment in the Wuchuan, Inner Mongolia. Results showed that LAI, biomass and fertilizer absorption could be significantly enhanced under the combination use of chemical and organic fertilizer (NPK+O) or balanced fertilization (NPK). The maximum LAI and biomass were 2.19 m2.m-2 and 136.53 g per plant. The maximum amount of absorption of N, P and K were 3.35 g, 0.36 g and 6.99 g per plant. Combination use of chemical and organic fertilizer (NPK+O) and balanced fertilization (NPK) could also enhance the potato yield, water use efficiency and fertilizer use efficiency. Potato yield could be increased by 110.57% and 85.44% compared with potato planted without fertilization under NPK+O and NPK condition. Under the condition of NPK+O and NPK, the commercial yield could be enhanced by 295.11% and 247.56%. Water use efficiency could be enhanced by 107.42% and 38.27%. The use efficiency of N, P2O5 and K2O were25.44%, 20.78% and 61.13%, respectively. The study could provide scientific basics for optimizing the fertilization of rainfed potato in the North Yinshan area. |
