绿萍(又称红浮萍)能肥田,又可以喂猪,因此有人主张利用冬水田秋繁绿萍作力饲料库,多产猪饲料,扩大肥源,很有前途。但有人却认为秋繁时间短,每亩只能产4,000—5,000斤,仅可为春繁提供种萍。究竟秋繁绿萍有没有前途?我们就这个问题进行了试验。试验结果表明,在增多用种量并增施腐植酸钠的情况下,绿萍四天可以繁殖一次,按照这样的快速繁殖,用绿萍做秋繁饲料库是有前途的。这个试验是在夹江县土门公社民益大队一队农科组进行的。试验田是一块收了中稻的冬水
Luping (also known as red duckweed) can fertile fields, but also can feed pigs, so some people advocate the use of winter paddy field autumn Fan Lvping for feed library, prolific pig feed, expanding fertilizer source, very promising. However, some people think that autumn flowering time is short, only 4,000-5,000 catties per acre, only for the spring to provide species Ping. After all, there is no future autumn Fanpula? We have conducted a test on this issue. The results showed that in the case of increasing the amount of used and adding sodium humate, Lvping could breed for four days. According to such rapid propagation, it is promising to use Lvjing as a feed for autumn rearing. This experiment is in Jiajiang County Tumen commune Minyi Brigade a team of agricultural science group carried out. The experimental field is a piece of winter water that received mid-season rice
