| 摘 要： | 为了探讨结缕草在盐碱地上的种子直播建坪应用，通过施用石膏改良盐碱土并增加播种量进行了结缕草草坪建植试验研究，结果表明：土壤石膏改良后草坪的出苗数（8058.5株/m2）、密度（7511.2株/m2）、高度（46.2mm）及盖度（92%）均显著地高于对照，分别是对照的1.6、1.7、1.6及1.4倍；改良后增加播种量（33%）的草坪的出苗数（8058.5株/m2）和密度（7511.2株/m2）显著地提高，成坪时间提前至少7天。 |

| Abstract: | The effects of increasing seeding rate on building Zoysia japonica turf by applying gypsum to improve alkaline soils were studied for the sake of the applying Zoysia japonica on alkaline soils. The results showed that the number of seedling (8058.5 stock/m 2 ), density (7511.2 stock/m 2 ), height (46.2 mm) and coverage (92%) were 1.7, 1.7, 1.2 and 1.4 times as great as CK and markedly greater than CK, respectively, when the soils were improved by applying gypsum. The number of seedling ( 8058.5 stock/m 2 ) ... |
