水稻是高产作物,但在我省历来以直播密植栽培为主,单产低而不稳定。近年来,通过采用水稻旱育稀植栽培技术,水稻单产有了大幅度的提高。为了明确旱育稀植条件下,“万亩千斤”的施肥技术及探讨进一步提高水稻产量的途径,于1985年我们在方正县永建乡进行水稻高产栽培施肥技术的研究,现将结果总结如下。 Rice is a high-yield crop, but in our province has always been to direct-seeded planting, low and unstable yields. In recent years, the rice yield has been greatly increased through the adoption of rice cultivation technology with dry cultivation and nurture. In order to clarify fertilization techniques under dry cultivation and rare planting conditions and to explore ways to further increase rice yield, we conducted a study on fertilization techniques of high-yielding rice in Yongjian Township, Founder County in 1985. The results are summarized as follows .
