配方施肥对铁心杉幼苗生长和生理生化指标的影响
Effect of formula fertilization on growth and physiological-biochemical characteristics of red-heart Cunninghamia lanceolate seedlings
摘要
Abstract
[Objective]The study aimed to find the suitable fertilization ratio for the growth of red-heart Cunninghamia lanceolate seedlings.[Method]14 groups of 1-year-old seedlings(50 pots per group)were treated with different fertilizer ratios,which were set up by"3414"experimental design scheme,to investigate the effect of fertilizer ratio on the growth and physiological-biochemical indexes of the seedlings.[Result]Compared with no fertilization,the chlorophyll content of leaves of red-heart C.lanceolate seedlings with reasonable fertilization increased up to 42.01%,soluble sugar content up to 11.64%,soluble protein content up to 13.81%,free proline content up to 211.25%,and the seedling height,root diameter,aboveground biomass of red-heart C.lanceolate seedlings under the fertilizer formulation of N2 P2 K1,underground biomass,total biomass and seedling quality index reached the maximum val-ue,and the ground diameter,root surface area and total root length were also in the middle to upper level.[Conclusion]N2 P2 K1(application of 1.0 g N,1.0 g P,0.5 g K per pot)was the best fertilizer formulation for red-heart C.lanceolate seedlings in this ex-periment.关键词
