摘　　要：研究了不同基追肥比例对深松耕栽培红麻农艺性状和产量的影响。试验设2种红麻品种,即福红992与红优2号;3种基追肥比例,即T1(20%氮肥作基肥,80%氮肥作追肥),T2(40%氮肥作基肥,60%氮肥作追肥)和T3(60%氮肥作基肥,40%氮肥作追肥)。结果表明,与对照相比,福红992的平均生麻产量和地上部干质量分别增加82.6%和220.1%,红优2号的平均生麻产量和地上部干质量分别增加99.8%和137.7%,差异均显著;与福红992相比,红优2号的平均生麻产量和地上部干质量分别增加15.3%和26.1%。研究表明在深松耕栽培方式下,不同类型红麻品种对基追肥比例的响应不同,常规栽培种福红992在T1时生麻产量和地上部干质量均达到最大值,而杂交种红优2号在T3时生麻产量和地上部干质量均达到最大值。The effects of different ratio between base fertilizer and topdressing on agronomic traits and yield of deep subsoiling tillage of Kenaf were studied. The field experiments included two kenaf varieties,i.e. Fuhong 992 and Hongyou 2;3 ratios between base fertilizer and topdressing, i.e. T1（20% N fertilizers as basal fertilizer and 80% N fertilizers as topdressing）,T2（40% N fertilizers as basal fertilizer and 60% N fertilizers as topdressing）,T3（60% N fertilizers as basal fertilizer and 40% N fertilizers as topdressing）. The results showed that, compared with the control group, the fiber yield and shoot dry mass of Fuhong 992 were increased by 82.6% and 220.1%, the fiber yield and shoot dry mass of Hongyou 2 were increased by99.8% and 137.7%. Compared with Fuhong 992,the fiber yield and shoot dry mass of Hongyou 2 were increased by 15.3%and 26.1%. In conclusion, in a deep subsoiling tillage mode, the yield and shoot dry mass of Fuhong 992 reached the maximum with T1;the fiber yield and shoot dry mass of Hongyou 2 reached the maximum with T3.
