摘要
该文在太湖强风浪湖滨带开展了菱的原位恢复试验,探讨了3种不同引种方式下的恢复效果。结果表明,幼苗移栽的方式在确保萌发率和菱种扎根深度方面具有优势,种群重建效果较好,但对育苗、运输、栽种环节要求较高;撒播菱种的方式在风浪扰动强的湖滨带成活率低,未能成功恢复;配重袋种植的方式下,菱种的扎根率、扎根深度、覆盖度和生物量均大幅提高,实现了种群恢复,适用于大规模强风浪湖滨带菱种群的恢复与重建。
Three different methods of Trapa L.restoration in a wind-stressed lakeside were studied according to in situ experiments.The results showed that the seedling transplanting method had advantages in ensuring the germination rate and the depth of seedlings,therefore the population reconstruction effect was much more efficiency.However,this recovery method has higher requirements for seedling raising,transportation,and planting.The sowing planting method had the lowest survival rate for Trapa L.and therefore the recovery of population was failure in the wind-stressed lakeside.The rooting rate,rooting depth,coverage,and biomass of Trapa L.were increased remarkably and therefore promote the population restoration according to the method of weight bag planting.This method should be considered in the large scale of Trapa L.population restoration in wind-stressed lakeside.
