在乌鲁木齐县板房沟乡前山带退化荒漠草地上,用扁穗冰草、中间冰草、驼绒藜、木地肤、四翅滨藜等5种牧草进行临冬和早春两个时期播种;土壤处理方面进行全面松土、行内松土、不动土3种处理方式补播。最后确定适宜当地补播的牧草种类,补播时期,土壤处理和补播深度等。试验结果表明,扁穗冰草和驼绒藜在临冬时期进行行内松土补播,而且补播深度控制在1~4 cm时,扁穗冰草的出苗率及成活率分别为22.24%,95.24%;驼绒藜为10.58%和90.00%。
In the degraded desert grassland of Banfugou Township in Urumqi County, five kinds of forage grass such as Agropyron cristatum, Agropyron cristatum, Ceratoides arborescens, Cortex Mucuna and Atriplex were planted in both winter and early spring. Soil To deal with a comprehensive loosening of soil, within the line of loosening, non-existent three ways of replenishment. Finally determine the appropriate local rewatching forage species, replenishment period, the depth of soil treatment and replantation. The results showed that the emergence and survival rates of Agropyron chinense and Ceratoides fulva were interplanted with intraplantation in the late winter, and the depth of replanting was 1 ~ 4 cm, the emergence rate and survival rate were respectively 22.24% and 95.24 %; Ceratoides are 10.58% and 90.00%.
