菌根生物制剂对樟子松苗木生长和根际土壤养分的影响
|
摘要
在内蒙古和盛生态育林有限公司的赤峰赛罕乌拉综合防护林示范基地,以樟子松苗木和菌根生物制剂为研究材料,对比测定施用和未施用菌根生物制剂的樟子松苗木的(高、径、冠幅)生长量、生物量及根冠比、根际土壤养分(有机质;全N、全P、全K含量),并测定了樟子松苗木的菌根化率。结果表明:菌根生物制剂处理的菌根苗比普通苗的平均苗高增长24.80%,平均地径增长33.30%,平均冠幅增长26.40%;菌根苗的平均地上生物量鲜重和干重分别比普通苗高149.9%和164.3%,平均地下生物量的鲜重和干重分别比普通苗高94.8%和75.4%;菌根苗的根际土壤有机质含量比普通苗高1.88%,全N含量比普通苗高86.59%,全P含量比普通苗高54.64%,全K含量比普通苗高59.40%;菌根生物制剂处理苗木的菌根化率与苗高呈现正相关。
In Chifeng Sai Han wula comprehensive shelterbelt demonstration base of Inner Mongolia hesheng ecological afforestation co.,ltd.,take Pinussylvestris var. mongolica seedlings and mycorrhizal biological preparation as research materials,The growth( Height,diameter,crown width),biomass and root-shoot ratio of Pinussylvestris var. mongolica seedlings with and without mycorrhizal biological agents were determined; Biomass and root/crown ratio; Rhizosphere soil nutrients( organic matter; All N,all P,all K content),The mycorrhizal rate of Pinussylvestris var. mongolica seedlings was measured.The results show that: The average height of mycorrhizalseedl-ings treated with mycorrhizal biological agents increased by 24. 80 %,average ground diameter increased by 33. 3 0 %,and average crown width increased by 26. 40%; The fresh weight and dry weight of above-ground biomass of mycorrhizal seedlings were 149. 9 % and 164. 3% higher than that of common seedlings,respectively,while the fresh weight and dry weight of underground biomass were 94. 8 % and 75. 4 % higher than that of common seedlings,respectively; The content of organic matter in rhizosphere soil of mycorrhizal seedlings was 1. 88 % higher than that of common seedlings,the content of total n was 86.59 % higher than that of common seedlings,the content of total p was 54. 64 % higher than that of common seedlings,and the content of total k was 59. 40 % higher than that of common seedlings; The mycorrhizal rate of see-dlings treated with mycorrhizal biological agents was positively correlated with seedling height.
