生物土壤改良剂对兰引3号草坪的影响研究

Effects of biological soil ameliorators for turf quality of Zoysia japonica cv.Lanyin No.3

通过测定草坪质量、生物量、叶片含水量及叶绿素含量指标,研究了新型生物土壤改良剂对兰引3号结缕草越冬阶段的影响。结果表明:在越冬期,施用量为1.870 mL/m2的生物土壤改良剂处理的草坪质量优于其他处理;施用生物土壤改良剂2.805 mL/m2处理的叶片含水量、叶绿素含量及生物量高于其他各处理。在兰引3号结缕草越冬期施用生物土壤改良剂能明显促进其恢复生长。

The effects of new biological soil ameliorators in winter for turf quality of Zoysia japonica cv. Lanyin NO.3 were studied by measuring chlorophyll content, total biomass and leaf water content. The results showed that the turf quality which used 1.9 mL/m2 biological soil ameliorators surpassed than that of the other treatment in overwinteiing period. The use of 2.805 mL/m2 biological soil ameliorators were higher than the other treatment on leaf water content, biology content, and the chlorophyll content. By using the biological soil ameliorators, the Zoysia japonica cv. Lanyin NO.3 can obviously recover in overwintering period.
