有效微生物群对3个树种1年生容器苗生长的影响

Effects of Effective Microorganisms on the Growth of 1-Year-Old Container Seedlings of Three Tree Species

    摘要
  • 摘要: 以楠木、无患子和醉香含笑1年生容器苗为参试材料，采用叶面追施、基质追施及叶面结合基质追施的方式，研究有效微生物群（EM）500倍稀释液施用对其生长的影响。结果表明：7月底至8月底为苗高快速增长期，9月上旬为无患子地径快速增长期，9月中旬为楠木和醉香含笑地径快速增长期，EM的施用对3种参试植物苗高和地径的生长具有一定调节作用。与对照相比，苗高快速生长期之前，R_EM和（L+R）_EM处理中醉香含笑、楠木及无患子日均高生长分别增加133%、39%、248%和217%、256%、331%；高生长快速增长期间，R_EM和（L+R）_EM处理中受试容器苗日均高生长增加11%~88%。叶面施用EM未改变参试植物地径快速增长期的时间，基质施用EM促进了楠木和醉香含笑提早进入地径快速增长期，但对无患子无明显影响；基质施用EM对降低参试植物高径比（HDR）有一定促进作用，出圃时，（L+R）_EM处理中醉香含笑、楠木和无患子HDR比对照降低700%、420%和560%。EM的施用促进了容器苗根系的生长， L_EM、R_EM和（L+R）_EM处理中根系体积比对照分别增加了1604%、4074%和8074%，侧根体积分别增加了2490%、5136%和10003%，根系鲜质量分别增加了2000%、3580%和7599%，根系干质量分别增加了619%、2845%和6619%，根茎比分别增加了1385%、2191%和3940%。

     

    Abstract: An experiment was conducted to determine the effects of effective microorganisms (EM) solution diluted 500 times on the growth of 1yearold container seedlings of three tree species, Phoebe zhennan, Sapindus mukorossi and Michelia macclurei. Treatments included control (CK), foliar topdressing (L_EM), substrate topdressing (R_EM), combination foliar and substrate topdressing (L+R) _EM. The end of July to end of August, the fast growth in seedling height was observed. With respect to rapid growth in ground diameter，early September was for S. mukorossi and midSeptember was for both P. zhennan and M. macclurei. Application of EM could regulate the growth both plant height and ground diameter compared with CK. Before the rapid growth period in plant height, the average height growth rate of M. macclurei, P. zhennan and S. mukorossi respectively increased by 133%, 39% and 248% in the R_EM treatment, and respectively increased by 217%, 256% and 331% in the (L+R) _EM compared to CK. During the rapid growth period, the average height growth rate of the three species was increased by 11%-88% in R_EM and (L+R)_EM compared to CK. The period of rapid growth in ground diameter was not affected by L_EM for the three species, whereas the process was in advance in R_EM for P. zhennan and M. macclurei except, S. mukorossi. The ratio of height to diameter (HDR) decreased in R_EM and (R+L)_EM compared to CK. At the end of experiment, HDR of M. macclurei, P. zhennan and S. mukorossi decreased by 700%， 420% and 560%, respectively in (L+R)_EM. Application of EM could promote root growth of all species. Compared with the control, the increases of the parameters of roots such as root volume and root weight were observed in L_EM, R_EM and (L+R) _EM: root volume increased by 1604%, 4074% and 8074%. The volume of lateral roots was increased by 2490%, 5136% and 10003%, respectively. Root fresh weight was increased by 2000%, 3580% and 7599%, respectively. Root dry weight was increased by 619%, 2845% and 6619%. In addition, the dry weight ratio of root to stem in L_EM， R_EM and (L+R)_EM compared to CK was increased by 1385%, 2191% and 3940%, respectively. As a result, it was significance for improving the quality of 1yearold container seedlings using EM solution diluted 500 times to substrate topdressing.
