Abstract:
Climatic ecosystem characteristics of perennial farmland lotus root, isn't fully alike with the annual pond lotus root. By 3year 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.
