摘要
[目的]为了寻求两优6326的最佳栽培模式。[方法]对两系杂交组合两优6326进行栽培密度和施肥水平2个试验,密度试验设5个处理,施肥水平试验设4个处理。[结果]从实际产量结果来看,密度试验12.0万株/hm2的产量最高,折合9865.95kg/hm2;30.0万株/hm2的产量最低,折合9332.1kg/hm2。施肥水平处理1的产量最高,折合10293.45kg/hm2;处理2的产量最低,折合9454.35kg/hm2。从理论产量结果来看,密度试验22.5万株/hm2的产量最高,为13531.5kg/hm2,12.0万株/hm2的产量最低,为9865.95kg/hm2。施肥水平处理1的产量最高,为12412.50kg/hm2,处理2的产量最低,为9855.00kg/hm2。[结论]综合实际产量、理论产量等方面因素,提出两优6326的最佳栽培模式为:栽培密度22.5万株/hm2;基肥施尿素225kg/hm2,氯化钾150kg/hm2,过磷酸钙600kg/hm2;分蘖肥施尿素180kg/hm2,氯化钾120kg/hm2;穗肥施尿素45kg/hm2,氯化钾30kg/hm2。
[Objective] The study aimed to find the optimum cultivation model for Liangyou 6326. [Method] In two experiments of the cultivation density and fertilization level of two-line hybrid rice Liangyou 6326, 5 treatments （Ts） were set up in density experiment and 4 Ts were set up in fertilization level experiment. [Result] As for the actual yield, in density experiment, the conversion yield of 12.0×10^4 plants/hm^2 was highest, being 9 865.95 kg/hm^2, the conversion yield of 30.0×10^4 plants/hm2 being was lowest, being 9 332.1 kg/hm^2; in fertilization level experiment, the conversion yield of T1 was highest, being 10 293.45 kg/hm^2, the conversion yield of T2 was lowest, being 9 454.35 kg/hm^2. As for the theoretical yield, in density experiment, the yield of 22.5×10^4 plants/hm^2 was highest, being 13 531.5 kg/ hm^2, the yield of 12.0×10^4 plants/ hm^2 was lowest, being 9 865.95 kg/hm^2; in fertilization level experiment, the yield of T1 was highest, being 12 412.50 kg/ hm^2, the yield of T2 was lowest, being 9 855.00 kg/hm^2. [Conclusion] Combined with actual yield and theoretical yield and other factors, the optimum cultivation model of Liangyou 6326 was suggested as follows： cultivation density of 22.5×104 plants/hm^2; applying urea at 225 kg/hm^2, potassium chloride at 150 kg/hm^2, superphosphate at 600 kg/hm^2 as basic fertilizer; applying urea at 180 kg/hm^2, potassium chloride at 120 kg/hm^2 as tillering fertilizer; applying urea at 45 kg/hm^2, potassium chloride at 30 kg/hm^2 as spike fertilizer.
