增产原因分析 1 “双茎”栽培与常规(对照)栽培的生产进程比较,有“前缓后赶”的特点:“双茎”栽培的营养生长阶段,即出苗到现蕾,比对照长5～6天;营养、生殖生长并进阶段,即现蕾到终花,比对照短4～5天。 2 “双茎”栽培的生物产量和茎秆重的最大积累强度、平均积累强度和积累最快时的积累量,均高
Analysis of the reasons for the increase in yield 1 Comparison of the production process between “double-stem” cultivation and conventional (control) cultivation has the characteristic of “slowing down before harvesting”: the vegetative growth stage of “double stems” cultivation, that is, emergence to budding, ~ 6 days; nutrition, reproductive growth and advanced stage, that is, budding to final flower, shorter than the control 4 to 5 days. 2 The maximum accumulation intensity, average accumulation intensity and accumulative amount when the fastest accumulation of biomass and stem weight of “double-stem” cultivation were high
