中文摘要: 多熟制田藕气候生态特性,与单熟水塘莲藕不尽相同。用2003—2005年对春藕生长期与藕田
小气候平
行观测资料,分析了田藕喜温暖喜光照不耐低温连阴雨的基本特征,得出了幼苗生长期要求
日平
均气温≥13℃、立叶生长期≥15℃、莲鞭膨大期(结藕期)≥18℃的温度指标,和田藕完成
幼苗生长阶段、立叶生长阶段,以及进入后把叶出叶期(出藕始期)与鲜藕始采期所需要的
有效积温等热量指标。根据春藕中后期更容易遭受不利气象条件影响和春末夏初时有冷空气
入侵提出了以水调温灌水等生产技术,有利田藕增产和提早采收,利用天气气候等自然资源
的整合,促进了农业增效农民增收。
Abstract:Climatic ecosystem characteristics of perennial farmland lotus root, isn't fully
alike with the annual pond lotus root. By 3 year parallel observation
s with the lotus root's growth and the farmland microclimate, the basic characte
ristics are shown that the farmland lotus root requires warm and sunshine condit
ions, but can't bear the low temperature with the overcast and rainy. The temper
ature index of young sprout growth is expected to have the average daily air tem
perature ≥13℃, the temperature of first leaf's growth period≥15℃, and the pe
riod of lotus root's procreation≥18℃. Because the spring lotus root more easil
y suffers from the disadvantageous weather conditions in the anaphase and the co
ld air often invades in the end of spring and early summer, some techniques like
temperature adjustment with water and douche are put
forward for improving farmland lotus root production, better making use of the n
atural resources like weather and climate, and increasing the agriculture effect
and farmer's income.
