| 摘 要： | 采用桶栽方式，研究不同pH(5.0、7.0、8.5)营养液对甘蔗组合RB85–5156×云瑞05–407、云瑞06–3501×Tolodo、粤糖94–128×赣蔗75–65、ROC6×云瑞05–733、VMC87–95×云瑞05–171(分别记为A、B、C、D、E)实生苗生长的影响。结果表明：①在pH 7.0处理下，B组合实生苗的根长、根表面积、根体积、茎径最大，在pH 8.5处理下，A、C、D、E组合实生苗的根长、根表面积、根体积最大；②C、D、E组合实生苗的根系活力在pH 5.0时最高，B组合实生苗的根系活力在pH 7.0时最高。整体而言，A、B、C、D、E组合实生苗在营养液pH 7.0和pH 8.5处理下的根系形态和植株生长较好。

| Abstract: | This paper estimates the effect of the international intra-product specialization and interregional integration on China''s producer services agglomeration from general and regional levels based on the data of 30 provinces in China from 1995 to 2011. It is found that the intra-product specialization has a modest promoting effect on producer services agglomeration in China compared with interregional integration, and it only performs in eastern China currently. This result indicates that agglomerate development of China''s producer services may depend more on the national market integration due to the fact that China is at the lower end of the global value chain. In addition, there exists positive interactive effects between the intra-product specialization and interregional integration on producer services agglomeration. It means that with the pace of regional cooperation and its integration the promoting effect of intra-product specialization would be brought into full play. |
