杂交水稻在生产上将要大面积推广,发挥其增产的优势。杂交水稻在我地区栽培,对氮、磷、钾肥料效应如何,以及怎样搭配才算经济合理,才能达到高产目的,这是我地区杂交水稻生产急需试验和研究模索的问题。我们参照市化肥网的试验方案,同时又考虑到氮、磷、钾之间的交互作用,搞了以杂交水稻为重点的需肥正交试验。
Hybrid rice in the production of large-scale promotion will be to play its advantages of increased production. Hybrid rice cultivation in our region, the effect of nitrogen, phosphorus and potassium fertilizer how, and how to match is considered economically reasonable, in order to achieve high yield purposes, this is my area hybrid rice production test and study urgently problems. We refer to the municipal fertilizer network test program, taking into account the interaction between nitrogen, phosphorus and potassium, engage in hybrid rice as the key to fertilize orthogonal test.
