红萍、细绿萍的施肥技术,是当前稻田养萍及今后集约生产的关键措施之一。以营养液养殖红萍、细绿萍,通常是在进行某些试验时采用;至于能否长期连续使用,以及用后对繁殖速度、固氮活性、干物质重和无机成分的影响等问题的研究,则尚未见报导。为此,我们进行了几种无机营养液养萍效果的试验研究,现将结果整理如下。 Red duckweed, fine green duckweed fertilization technology is the current rice paddy and future intensive production of one of the key measures. The use of nutrient solution to culture red ping, fine green Ping, usually carried out in some experiments; As for the long-term continuous use, as well as post-use of the rate of propagation, nitrogen fixation activity, dry matter weight and inorganic components such as the impact of research , It has not been reported yet. To this end, we conducted several experiments on the effect of inorganic nutrient solution Yang Ping, the results are summarized below.
