红萍又名满江红,是一种自然漂浮的水生满江红科蕨类植物。据研究,每公斤干重的红萍中蛋白质含量为19～24％,葫萝卜素含量为150～230克。微量元素铁、锰、锌、钴等的含量也比其它植物多。因此,红萍是一种优质的饲料和绿肥。一、红萍的栽培放养技术 (1) 原种红萍繁殖田的选择与准备:原种红萍的繁殖工作主要在春天和秋天进行。稻田、池塘、沟渠、凹地的水面都可用来繁殖红萍。一般选择地块要求便于灌溉、排水和向阳。早春可用一些障栏 Hongping, also known as Man Jiang Hong, is a naturally floating Aquatic Fernaceae fern. According to the study, the dry weight of red per kilogram of protein content of 19 to 24%, carotene content of 150 to 230 grams. Trace elements iron, manganese, zinc, cobalt and other content than other plants. Therefore, Hongping is a good feed and green manure. First, the red duckweed cultivation stocking technology (1) Selection and preparation of the original species of red duck breeding: Breeding of the original species of red duck is mainly carried out in the spring and autumn. Paddy fields, ponds, ditches and hollow water can all be used to breed rhodiola. The general choice of plots requires easy irrigation, drainage and sunny. Some barriers can be used in early spring
