水浮莲是养猪的好饲料。它原产在广东省珠江三角洲一带,自57年引到平阳以来,证明生长良好,很受群众欢迎。水浮莲在浙南地区适宜生长的月份是4—11月,生长期达7个月,以7,8,9三个月生是长为旺盛。从11月起分蘖停止,营养体逐渐变小,这时如果不加保护,经二、三次降霜后即行枯萎死亡。这样看来,水浮莲的越冬是值得研究的问题。1959年多天,我所对水浮莲的种子繁殖进行研究并取得了成功。这样就使缺乏温水田地区水浮莲安全过冬的困难得到解决。现在将初步结果介绍如下:
Water lettuce is a good feed for pigs. Originally produced in the Pearl River Delta region of Guangdong Province, it has been well-received by the masses since it was introduced to Pingyang in 57 years. Water Luna in southern Zhejiang suitable for growth in the month is April to November, the growth period of up to 7 months to 7,8,9 three months is long for the strong. From November on tiller stop, vegetative body gradually smaller, then if unprotected, after two or three down frost wither die. In view of this, overwintering water lily is worth studying. Many days in 1959, I researched and succeeded in the seed breeding of water hyacinth. This has led to a lack of solution to the problem of lack of safe winter floras in the paddy fields. Now the preliminary results are as follows:
