磷素对豆科植物的根瘤形成数量和固氮作用等问题研究颇多,但是磷素与满江红的增殖和固氮作用的关系却很少研究,为了解决养殖满江红施用肥料问题,寻求以化肥配合代替萍饭(萍饭是浙南萍农用猪厩肥堆腐晒干磨碎成粉状用来养殖满江红的肥料,也有称栏粉),探讨养殖满江红达到“以磷换氮”之目的,几年来我们对磷素肥料在满江红养殖利用上作了一些试验研究,现将其结果整理于后,供参考。 However, there is little research on the relationship between phosphorus and Azolla proliferation and nitrogen fixation. In order to solve the problem of fertilizing Manchurian red pepper, Rice (Pingfan is a farmer’s farm in Zhejiang Province Pingtung heap of pigs dried and ground into a powder used to cultivate Manchurian fertilizer, also called Fen column powder), to explore the breeding Azolla to achieve “the purpose of phosphorus to nitrogen,” the past few years we Phosphate fertilizer in the use of Manchurian breeding made some experimental studies, the results are now sorted out for reference.
