摘要: 为了明确‘两优616’秧龄、移栽密度与施氮量对产量的综合影响,探求该品种中稻高产栽培技术措施,应用311‐A拟饱和最优回归设计试验方案,通过田间试验建立中稻‘两优616’秧龄、移栽密度、施氮量与产量的数学(回归)模型。结果表明,各因素对产量的影响顺序为施氮量>移栽密度>秧龄;经模拟寻优与筛选,最优组合是秧龄30.7d,移栽密度20.61万丛/hm2,施纯氮168.97 kg/hm2时,拟获得的最高产量为9770.8 kg/hm2;中稻‘两优616’产量≥8625 kg/hm2的主要农艺措施为秧龄29~33d,移栽密度17.2~22.2万丛/hm2,施纯氮161.0~190.4kg/hm2。

Abstract: To reveal the integrative effects of seedling age, transplanting density and nitrogen application rate on yield of middle-season rice‘Liangyou 616’, and study its high-yield cultivation technique, an experiment was designed by using the 311-A optimum regression, and a mathematics (regression) model was established between yield and the factors, seedling age, transplanting density and nitrogen application rate in the filed experiment. The results indicated that the effect of the three factors on yield was as following: nitrogen application rate >transplanting density > seedling age. With the simulation and optimization by computer, the results suggested that the optimal combination was seedling age of 30.4d, transplanting density of 204600 clump/hm2,and net N fertilizer of 168.75 kg/hm2, and the imitated highest yield was 9778.1 kg/hm2. The main agronomic measures of‘Liangyou 616’to achieving the yield of more than 8625 kg/hm2 were seedling age of 29-33 d, transplanting density of 172000-227000 clump/hm2 and net N application rate of 160.0-190.8 kg/hm2.
