红萍,又叫绿萍、满江红、三角萍、红浮萍和红瓢,是一种适应范围很广,应用价值很大的水生草本植物。近年来,江苏、浙江、安徽、四川、广东等省都在大力推广放养。北方一些地区也已试养成功。红萍的用途红萍是一种很好的水生青饲料。据分析,萍体中含粗蛋白质16.15％,粗脂肪2.17％,比许多青饲料含量都高;而含粗纤维只有0.7％,比其他青饲料的含量都少。红萍营养丰富,萍体幼嫩松软,不仅猪爱吃,鸡、鸭、鹅都喜欢吃,也是塘鱼的好饲料。用红萍饲猪,可以生喂,也可以青贮或晒干,省工、省柴、省精料。红萍又是一种优质绿肥。其叶片的共生腔中有鱼腥藻共生,可以把空气中的氮素吸收固定到萍体内,固氮增肥。经化学分析,鲜萍含有氮素0.25％,磷酸
Hongping, also known as Lupin, Azolla, Triangle Ping, red duckweed and red ladle, is a wide range of adaptation, application of great aquatic plants. In recent years, Jiangsu, Zhejiang, Anhui, Sichuan, Guangdong and other provinces are vigorously promoting stocking. Some areas in the north have also been successfully tested. Hongping Hongping is a very good aquatic green feed. According to the analysis, Ping Pin body contains 16.15% of crude protein, crude fat 2.17%, higher than many green feed; and containing only 0.7% crude fiber, less than other green feed content. Hongping nutrient-rich, tender and tender body, not only pigs love to eat, chickens, ducks, geese like to eat, but also a good feed pond. Feeding the red duckweed, you can feed, you can silage or dried, labor, firewood, provincial concentrate. Hongping is a high-quality green manure. Anabaena symbiosis chamber of its leaves symbiotic, nitrogen absorption in the air can be fixed to Ping body, nitrogen fixation. After chemical analysis, fresh Ping contains nitrogen 0.25%, phosphoric acid
