荷花的生态习性荷花与水深荷花为水生花卉,喜相对稳定的静水,不喜流速较急、涨落悬殊的流水。不同类型品种对水深要求有别,大株型品种如‘洪湖红莲’、‘普者黑红荷’等,适宜在50cm～200cm水中生长,但最适合水深为50cm;小株型荷花如‘小天使’、‘金珠落玉盘’等生长适宜水深约10cm～20cm。籽莲产区种植籽莲时,其水深多控制在15cm～30cm,这是莲农千百年来总结的最适合荷花生长的水位。同一品种在整个生育期中的不同阶段,对水深的要求也不同。初期宜浅水位,随着气温的不断上升,荷梗高度不断增加,可逐步加深水位。荷花与温度农谚云:“三月三,藕出苫,九月九,挖野藕”。荷花最适宜生长的温度为22℃～32℃,对35℃～
Lotus ecological habits Lotus and water depths of flowers for the aquatic flowers, hi relatively stable still water, do not like the more urgent flow, fluctuating water. Different types of varieties of water depth requirements are different, large plant varieties such as’ Honghu Honglian ’,’ Pulu black Honghe ’and so on, suitable for growing in 50cm ~ 200cm water, but the most suitable depth of 50cm; small plants such as’ Little Angel ’,’ Golden Pearl Jade Tray ’and other growth suitable depth of about 10cm ~ 20cm. When seedling is planted in the seedling lotus seed production area, its water depth is controlled at 15cm ~ 30cm, which is the most suitable lotus growth water level summed up by Liannong for thousands of years. The same species throughout the growing period of different stages, the water depth requirements are also different. Initial shallow water level, with the rising temperature, increasing the height of the pedicel, can gradually deepen the water level. Lotus and temperature farming saying goes: “March 3, lotus root out 苫, September 9, Dig wild lotus root.” Lotus most suitable temperature for growth is 22 ℃ ~ 32 ℃, 35 ℃ ~
