水生蔬菜在不同的生长时期,对水层要求不同,过深或过浅对产量或品质的影响都很大。本人通过参与莲藕、茭白、荸荠三种水生蔬菜的生产实践,现将其管水技术总结如下,仅供参考。 1.莲藕 一般浅水藕以不超过0.5米为宜,深水藕以0.5～1米深为宜。具体管理如下: 种藕下田后至萌芽期灌浅水层8～10cm,提高
Aquatic vegetables in different growth stages, different requirements of the water layer, too deep or too shallow on the yield or quality are great. I participated in the production of three kinds of aquatic vegetables, including lotus root, wild rice and water chestnut, and summarized their water management technologies as follows for reference only. 1. Lotus root shallow water lotus root to no more than 0.5 meters is appropriate, deep-root lotus root to 0.5 to 1 meter deep is appropriate. Specific management is as follows: kinds of lotus root after the field to the sprouting irrigation shallow aquifer 8 ~ 10cm, increased
