近年来,细绿萍在我县的养殖有了发展,其利用形式也有所革新。但是由于细绿萍的萍体组织膨松,不易翻埋入土。目前所用的一些倒萍方法都不太理想。化学倒萍是一种比较彻底的倒萍技术,但其对水稻生长和肥效的关系如何,尚未进行认真的研究。为了进一步明确各种倒萍方法的优劣点,克服应用上的盲目性,提高萍肥的利用率,我站于一九八一年在华阳大队进行了化学倒萍技术的试验。
In recent years, Fine Green Lvping in our county farming has developed its use of the form has also been innovative. However, due to the thin green Pingping bulk organization, not easily buried buried. Some of the currently used methods are not ideal. Chemical pouring is a more complete inverted duckweed technology, but its relationship on rice growth and fertilizer efficiency, but not serious study. In order to further clarify the merits and demerits of various methods and overcome the blindness in application and improve the utilization rate of Pingfei, I experimented with chemical Pingping technology in Huayang Brigade in 1981.
