为探索金秋香优1079的高产配套栽培技术,采用L9(34)正交设计研究了追肥施氮量、氮肥作蘖肥与穗肥施用比例和移栽密度对金秋香优1079产量的影响。结果表明:追肥施氮量、氮肥作蘖肥与穗肥施用比例和移栽密度对金秋香优1079的产量均有显著影响,各因素对产量的决定程度为移栽密度>追肥施氮量>氮肥作蘖肥与穗肥施用比例;各因子水平的最佳组合为A2B2C1,即追肥施氮量为150 kg/hm2、氮肥作蘖肥与穗肥施用比例为7∶3、每公顷栽15万穴时金秋香优1079可以获得较高产量。
In order to explore the high-yielding cultivation techniques of Jinqiu 1079, the effects of topdressing nitrogen rate, proportion of nitrogen fertilizer applied for tillering and panicle fertilization and transplanting density on the yield of Jinqiu Xiangyou 1079 were studied by L9 (34) orthogonal design. The results showed that: topdressing N application rate, N fertilizer application ratio of tillering fertilizer and panicle fertilizer and transplanting density had significant effects on the yield of Jinqiuyouyou 1079, and the decisive degree of each factor on the yield were the transplanting density> topdressing nitrogen> The ratio of nitrogen fertilizers to tillering and panicle fertilization was the best. The best combination of each factor was A2B2C1, that is, topdressing nitrogen was 150 kg / hm2, nitrogen fertilizer was 7: 3 for tillering and panicle fertilization, and 150,000 Golden Autumn Champion point 1079 can get higher yields.
