| 摘 要： | 为了研究不同基质和育苗条件下对梭梭生长发育的影响,以梭梭为材料,比较了3种不同基质配置和两种育苗条件对梭梭生长状况的影响。结果表明:小拱棚育苗和露天育苗条件下,最佳播种育苗基质均为园土∶河沙∶腐熟羊粪=1∶1∶1;同种基质下,小拱棚育苗方式均比露天育苗方式下苗木生长好。播种时,采用小拱棚营养袋育苗方式、播种基质以园土∶河沙∶腐熟羊粪=1∶1∶1的苗木生长量最好。苗木平均苗高、平均地径、平均主根长、一级侧根长、苗木重量分别达39.28 cm、0.19 cm、11.83 cm、7.45 cm、6.87 g。

| Abstract: | In order to study the effect of different substrates on the growth and development of Haloxylon ammodendron under different seedling growth conditions,using H.ammodendron as the studying materials,the effects of three different substrate configurations and two seedling growth conditions on the growth conditions of H.ammodendron were studied.The results showed that:(1)under the conditions of small arch shed nursery and open-air nursery,the best nursery substrates were both garden soil:river sand:decomposed sheep manure=1:1:1.(2)under the same substrate,the seedling growth in the small arch shed nursery methods was better than that in open-air nursery.(3)when sowing,the seedling growth rate was the best when using the small arch shed nutrient bag nursery method and the nursery substrate was garden soil:river sand:decomposed sheep dung=1:1:1.The average seedling height,average ground diameter,average main root length,first-class side root length,and seedling weight was 39.28 cm,0.19 cm,11.83 cm,7.45 cm,and 6.87 g respectively. |
