烤烟品种NC102高产配套栽培技术研究

Cultivation Technique for High Yield of Tobacco Variety NC 102

为烤烟品种NC102在云南烟区的大面积推广种植提供参考,在云南省石林县板桥镇马街村进行了施氮量、株行距、留叶数、打顶时期4因素3个水平对该品种产量、产值影响的正交试验。结果表明:施氮量、施氮量与株距互作对NC102产量的影响极显著,株距、留叶数的影响显著;施氮量、株距、施氮量与互作株距对产值的影响极显著,留叶数的影响显著;各因素对NC102产量与产值的影响程度依次为施氮量>施氮量与株距互作>株距>留叶数。NC102品种的田间最佳技术措施组合为施纯氮量6.5kg/667m2、株距0.6m、留叶数20片、现蕾打顶。

The effects of nitrogen amount,planting space,remained leaves and topping stage on yield and output value of tobacco variety NC102 were tested by the orthogonal design in Shilin County,Yunnan to provide a reference for large-scale popularization of tobacco variety NC102 in Yunnan.The nitrogen amount and interaction between nitrogen amount and plant spacing have the very significant effect on yield of NC102.Planting space and remained leaves have the significant effect on yield of NC102.Nitrogen amount,interaction between nitrogen amount and plant spacing and planting space have the very significant effect on output value of NC102,but remained leaves has the significant effect on output value of NC102.The factors affecting yield and output value are nitrogen〉 interaction between nitrogen amount and plant spacing〉planting space〉remained leaves.The optimum technical combination for high yield and output value of NC102 includes 6.5 kg/667m2 of pure nitrogen,0.6m planting space,20 remained leaves and topping at budding stage.
