水浮莲和水葫芦是猪很爱吃的水生饲料,养得好,一亩水面可产十五万到二十万斤,但它们是南方植物,喜高温,最适宜的温度是24至27度,16至20度生长缓慢,12至15度仅能维持生命,7度以下就会死亡。因此,保种越冬就成了大问题。去年冬季我县有24个地方搞了水浮莲和水葫芦的越冬试验,方法有:温池、温床盆养、自然池和分户盆养。11个地方试验成功,其余因没固定专人负责,管理不善,所以失败。试验 Water lily and water hyacinth are pigs love to eat aquatic feed, well-fed, one acre of water can produce 150,000 to 200,000 kg, but they are southern plants, like high temperature, the most suitable temperature is 24 to 27 Degrees, slow growth of 16 to 20 degrees, 12 to 15 degrees only life, below 7 degrees will die. Therefore, overwintering conservation has become a big problem. Last winter, 24 counties in our county carried out wintering experiments on water hyacinth and water hyacinth. The methods include: warm pool, hotbed, natural pool and household basin. Eleven local trials were successful, and the rest failed because they did not have a dedicated person in charge and mismanagement. test
