芸豆新品种品金芸1号高产栽培模式研究

High Yield Cultivation Model Study on New Kidney Bean Variety Pinjinyun 1

采用三元二次正交旋转组合设计,对芸豆新品种品金芸1号高产栽培模式进行研究,结果表明,品金芸1号产量与行距、密度、施纯N量等3个栽培因素相关的数学模型为Y=2 076.666 1+16.325 40X1-21.194 06X2+156.666 25X3-39.634 66X12-28.886 64X22-91.642 37X32-2.525 00X1X2+12.275 00X1X3+28.025 00X2X3。通过分析寻优确立了品金芸1号获得2 141 kg/hm2产量水平的优化方案是行距50 cm,密度150 000株/hm2,纯N施用量30 kg/hm2(尿素的46%折算纯N);行距、密度、施纯氮量对芸豆新品种品金芸1号产量的影响达93.27%;各因素对品金芸1号产量的影响是施纯N量>密度>行距。

By adopting ternary quadratic orthogonal rotating combination design, the relationship between row spacing, density and nitrogen rate and the yield of new kidney bean variety Pinjinyun 1 was studied to provide theoretical basis for high yield cultivation. The results showed that,the related mathematical model between the yield of Pinjinyun 1 and three cultivation factors （row spacing, density, nitrogen rate and so on ）was Y = 2 076.666 1＋16.325 40Xr21.194 06X2＋156.666 25X3-39.634 66X12-28.886 64X22-91.642 37X32-2.525 00X1X2＋12.275 OOXIX3＋28.025 00X2X3;By optimal analysis,we established that optimization scheme to obtain the yield level over 2 141 kg/hm2 was row spacing 50 cm, density 150 000 plants/bin2, pure nitrogen rate 30 kg/hm2 （46% of urea reduced pure nitrogen ） ; The effect of row spacing, density, nitrogen rate to the yield of new kidney bean variety Pinjinyun 1 was 93.27% and the effect of each factor was nitrogen rate〉density〉row spacing.
