【摘要】 以4个高产水稻品种为材料在云南省永胜县涛源乡进行精确定量栽培研究。结果表明,不同品种的总叶龄数不同,但差异较小。在理想气候的条件下,基础产量为10．5 t／hm2,基础供氮量120-165 kg／hm2。按精确定量技术栽培的水稻产量都在16 t／hm2,明显比常规栽培法增产,并能省工节本。使用精确定量栽培技术,涛源水稻还有较大的增产潜力。更多还原

【Abstract】 Field experiments to research the precise and quantitative cultivation in rice were conducted at Taoyuan township, Yong-sheng county in Yunnan province, which is one of the most famous places for high grain yield in rice. The results shown: the difference of leaf number of varieties was very small. At Taoyuan township, the grain yield of rice was about 10.5 t/hm2 without nitrogen application and the soil can support N 120 -165 kg/hm2 . The average grain yield of rice was 16 t/hm2 by using precise and quantitative cultivation. By using this method seed and fertilize were saved and more grain yield were got.更多还原
