| 摘 要： | 目的]探讨红麻对不同耕作和施氮方式的响应,为红麻高产高效栽培提供合理的耕作和施肥依据.方法]通过二因素三水平大田试验,研究耕作和施氮方式对红优2号生麻产量与农艺性状的影响.设3种耕作方式,A：免耕,B：垄耕,C：深松耕（深度30 cm）;3种N肥施氮方式,T1：20％作基肥、80％作为追肥,T2：40％作基肥、60％作为追肥,T3：60％作基肥、40％作为追肥,共9个处理组合.结果]免耕时,AT1处理组合的红麻株高、茎粗、皮厚等农艺性状及生麻产量、种子产量、地上部干重等产量性状均达最大值;垄耕和深松耕时,BT3和CT3处理组合的株高、茎粗、皮厚等农艺性状及生麻产量、种子产量、地上部干重等产量性状均达最大值;与免耕相比,深松耕的生麻产量、种子产量和地上部干重分别增加26.5％、19.1％和21.1％,差异显著（P＜0.05）.结论]深松耕组合40％作为追肥;生麻产量和地上部干重均达到最大值;深松耕组合60％作追肥,种子产量达到最大值.

| Abstract: | Objective]The responses of kenaf towards different tillage and fertilization methods were explored to provide reasonable tillage and fertilization references for high-yield and efficient kenaf cultivation. Method ]Field experi- ments with two factor and three levels were conducted to evaluate the effects of tillage and nitrogen methods on agronomic traits and yield of Hongyou 2. Three tillage methods （A： no tillage, B： ridge tillage, C： subsoiling tillage ） and three fertil- ization methods were designed （T1： 20% N fertilizers as basal fertilizer, 80% N fertilizers as topdressing; T2： 40% N fer- tilizers as basal fertilizer, 60% N fertilizers as topdressing, and T3： 60% N fertilizers as basal fertilizer, 40% N fertilizers as topdressing）. There were nine treatments. Result]In no tillage,plant height,stem diameter,thickness,fiber yield, seed yield and shoot dry mass of AT1 reached the maximum. In ridge tillage and subsoiling tillage, plant height, stem diam- eter, thickness ,fiber yield, seed yield and shoot dry mass of BT3 and CT3 reached the maximum. Compared to no tillage, fiber yield,seed yield and shoot dry mass of Hongyou 2 in subsoiling tillage increased by 26.5%, 19.1% and 21.1%, re- spectively （P〈0.05）. Conclusion]Fiber yield and shoot dry mass reached the maximum when subsoiling tillage and 40% N fertilizers as basal fertilizer were applied, while seed yield reached the maximum when subsoiling tillage and 60% N fertilizers as basal fertilizer were applied. |
