中文摘要	采用盆栽试验研究了Pt菌剂、ABT生根粉、HRC吸水剂和FCS丰产素等生物制剂对沙地樟子松2年生幼苗光合特征和养分含量的影响,结果表明:Pt菌剂(3号)和ABT生根粉与对照相比,显著地促进了樟子松幼苗全株、地下和地上生物量生长,并增加了幼苗的根冠比值,有利地促进幼苗对养分的吸收;Pt菌剂(3号)和ABT生根粉处理的幼苗叶子养分全N、P、K含量显著地高于对照幼苗,促进了幼苗养分的平衡,为提高光合作用能力提供了物质基础;Pt菌剂(3号)和ABT生根粉处理幼苗与对照相比,光合速率和蒸腾效率显著增强.这些是提高樟子松苗木在干旱、半干旱沙地成活生长的生理基础.
英文摘要	An experiment was conducted to study the effect of Pt ectomycorrhizal fungi,ABT root-growing powder,HRC water-absorbing agent and FCS high-yield powder on the photosynthetic characteristics and nutrient contents of 2-year-old Mongolian pine(Pinus sylvstris var.mongolica) potted seedlings.Results showed that Pt3 and ABT significantly increased the whole plant biomass,underground and aboveground biomass as well as the ratio of root to shoot of seedlings compared with those of the control,which could promote the absorption of main nutrients.Contents of N,P and K in the needle of seedlings treated with Pt3 and ABT were significantly higher than those of the control seedlings,which promoted the balance of different nutrients and provided the basic substances for improving photosynthetic ability.Pt3 and ABT greatly improved the physiological mechanism of seedlings and increased photosynthetic rate and transpiration rate.Therefore,Pt3 and ABT could improve the main physiological functions of Mongolian pine seedlings,which are beneficial to increase survival rate of seedlings in arid and semi-arid sandy lands.
