摘要
为研究不同施肥方式对杉木实生轻型基质容器苗生长的影响,2021年笔者以指数施肥E60和常规施肥C602种施肥方式培育的杉木容器苗为研究对象,开展生长量、生物量、质量指数(QI)值和根系状态测定,分析不同施肥方式容器苗生长差异。结果表明:不同施肥方式培育的容器苗7个月时,指数施肥方式培育的杉木轻型基质容器苗高、地径、高径比、茎叶干重、根部干重、总干重、根冠比、细根干重、中根干重、粗根干重和QI值分别为39.5 cm、4.9 mm、81.0、5.15 g、1.31 g、6.47 g、0.26、0.88 g、0.15 g、0.29 g和0.08;常规施肥方式培育的杉木轻型基质容器苗高、地径、高径比、茎叶干重、根部干重、总干重、根冠比、细根干重、中根干重、粗根干重和QI值分别为29.6 cm、4.0 mm、73.1、3.05 g、0.88 g、3.93 g、0.29、0.60 g、0.16 g、0.12 g和0.05。综合对比分析,指数施肥方式明显优于常规施肥方式培育的杉木轻型基质容器苗。
In order to study the effects of different fertilization methods on the growth of Chinese Fir Seedling in light substrate container.In 2021,the container seedlings of Cunninghamia lanceolata cultivated by exponential fertilization E60 and conventional fertilization C60 were studied,Carry out the measurement of growth、biomass、quality index(QI)value and root state,The growth differences of container seedlings under different fertilization methods were analyzed.The results show that:When container seedlings cultivated by different fertilization methods are 7 months old,Seedling height of light substrate container of Cunninghamia lanceolata cultivated by exponential fertilization、Ground diameter、height diameter ratio、Stem and leaf dry weight、root dry weight、Total dry weight、root shoot ratio、Fine root dry weight、medium root dry weight、coarse root dry weight and Qi values were 39.5cm、4.9mm、81.0、5.15g、1.31g、6.47g、0.26、0.88g、0.15g、0.29g and 0.08 respectively;Seedling height of Chinese fir cultivated by conventional fertilization in light substrate container、Ground diameter、height diameter ratio、Stem and leaf dry weight、root dry weight、Total dry weight、root shoot ratio、Fine root dry weight、medium root dry weight、coarse root dry weight and Qi values were 29.6cm、4.0 mm、73.1、3.05g、0.88g、3.93g、0.29、0.60g、0.16g、0.12g and 0.05respectively.Comprehensive comparative analysis,The light substrate container seedlings of Cunninghamia lanceolata cultivated by exponential fertilization were significantly better than those cultivated by conventional fertilization.
