旬阳县不同烤烟品种适宜施肥量的研究

目的]为了确定烤烟最佳施肥水平。方法]在旬阳县烟草种植区,以贵烟4号、中烟100、QY96(CK)为材料,研究不同施肥水平对烟草农艺性状、产量和抗病能力的影响。结果]在农艺性状方面,各烤烟品种在高肥区最好,中肥区次之,低肥区较差。在抗病毒方面,中烟100抗黑胫病。在品质方面,贵烟4号、中烟100原烟外观质量好,秦烟96原烟外观质量较好。在产量方面,中烟100品种在高施肥水平下产量高;贵烟4号品种在中、低等施肥水平下高;秦烟96品种适宜在中等施肥水平。结论]针对不同施肥水平对烟草农艺性状、产量和抗病毒能力等的影响,确定贵烟4号、中烟100、QY96(CK)的最佳施肥水平。

Research of Optimal Fertilizing Amount of Flue-cured Tobacco Varieties in Xuyang County

Objective] The research aimed to define the optimal fertilizing amount of flue-cured tobacco.Method] The effects of different fertilizing amount on the tobacco agronomic traits,yield and disease resistance ability of Guiyan 4,Zhongyan 100 and QY96（CK） in Xuyang County were studied.Result] All varieties behaved best from agronomic traits in high fertilization levels,followed by moderate fertilization levels and poor in low fertilization levels.Zhongyan 100 could anti-black shrank.The production of Zhongyan 100 in high fertilization levels was high,that of Guiyan 4 in moderate and low fertilization levels was high,and that of QY96（CK） in moderate fertilization levels was high.Conclusion] According to the obacco agronomic traits,the yield and the disease resistance ability,the optimal fertilizing amount of Guiyan 4,Zhongyan 100 and QY96（CK） could be determined.
