摘　　要：以大面积推广的优质常规稻品种云恢290为材料,以当地栽培技术(T1)为基础,在当地技术上实行精确定量施肥(T2),在T2基础上实行精确定量灌溉(T3),并通过定量基本苗、扩大行距、精确定量施肥和灌溉,实现精确定量栽培(T4),分析不同栽培技术对云恢290生育期、叶龄、产量及其构成和经济效益的影响。结果表明,相比T1处理,T2、T3和T4处理均能显著提高云恢290产量和经济效益,2019年产量增幅为21.0%~41.0%、经济效益增幅为20.6%~41.3%,2020年产量增幅为16.7%~65.4%、经济效益增幅为17.0%~63.8%,其中,T4处理增产增效最显著,产量极显著高于其他3个处理。可见,精准定量栽培技术是一种高产高效的栽培方式。The effects of different cultivation techniques such as local cultivation technology(T1),implement accurate quantitative fertilization(T2),accurate quantitative irrigation(T3),and integrative precise and quantitative cultivation technology(T4),on the growth period,leaf age,yield,yield composition and economic benefits of rice Yunhui 290,a large-scale popularized high-quality conventional rice variety were studied in Gejiu,Yunnan,China.The results showed that compared with T1 treatment,T2,T3 and T4 treatments significantly increased the yield by 21.0%~41.0%in 2019 and by 16.7%~65.4%in 2020,and increased the economic benefits by 20.6%~41.3%in 2019 and by 17.0%~63.8%in 2020.Among them,the T4 treatment had the most significant increase in yield and economic benefits,and the yield was extremely significantly higher than the other three treatments.The precise and quantitative cultivation technology is a high-yield and efficient cultivation method.The precise and quantitative cultivation method is a suitable cultivation method for high-quality conventional rice with high yield and efficiency.
