| 摘 要： | 为探索烤烟适宜的轮作模式,完善以烤烟为主的种植制度,研究了小麦—玉米—烤烟(M1)、小麦—花生—烤烟(M2)、小麦—大豆—烤烟(M3)、小麦—芝麻—烤烟(M4)、小麦—红薯—烤烟(M5)、烤烟—大麦绿肥—烤烟(M6)、烤烟—冬闲—烤烟(M7)7种模式对烤烟前茬土壤养分、根系活力及烟叶质量的影响。结果表明,M1模式烤烟前茬土壤碱解氮含量较高(88.14 mg/kg),水溶性氯含量最高(32.08 mg/kg),烤烟根系活力较低,烟叶质量较差;M2模式碱解氮含量较高(73.17 mg/kg),速效磷含量最低(10.04 mg/kg),根系活力前期低后期高,烟叶质量最差;M3模式碱解氮含量较高(76.94 mg/kg),烤烟根系活力一般,烟叶质量较差;M4模式碱解氮含量适中(63.98 mg/kg),根系活力较高,烟叶质量中等;M5模式碱解氮含量适宜(68.70 mg/kg),速效磷含量最高(17.36 mg/kg),烟叶质量好;M6模式碱解氮含量适宜(63.20 mg/kg),根系活力较低,烟叶质量较好;M7模式碱解氮含量适宜(67.03 mg/kg),根系活力较低,烟叶质量中等。综上,M4、M5、M6为烤烟适宜的轮作模式,M7(连作年限2 a)为较适宜模式,M1、M3为较不适宜模式,M2为不适宜模式。

| Abstract: | To explore the appropriate rotation patterns and improve the cropping system of flue-cured tobacco,the effects of 7 patterns wheat-corn-flue-cured tobacco (M1),wheat-peanuts-flue-cured tobacco (M2),wheat-soybeans-flue-cured tobacco (M3),wheat-sesame-flue-cured tobacco (M4),wheat-sweet potato-flue-cured tobacco (M5),flue-cured tobacco-barley green manure-flue-cured tobacco (M6) and flue-cured tobacco-winter fallow-flue-cured tobacco (M7)] on the previous crop soil nutrients,root activity and leaf quality of flue-cured tobacco were studied.The results showed that M1 had higher content of alkali-hydrolyzed nitrogen (88.14 mg/kg),highest content of water soluble chloride (32.08 mg/kg),lower root activity and poorer leaf quality;M2 had higher content of available nitrogen (73.17 mg/kg),lowest content of available phosphorus (10.04 mg/kg),former low-later high root activity and poorest leaf quality;M3 had higher content of alkali-hydrolyzed nitrogen (76.94 mg/kg),medium root activity and poorer leaf quality;M4 had medium content of alkali-hydrolyzed nitrogen (63.98 mg/kg),higher root activity and medium leaf quality;M5 had appropriate content of available nitrogen (68.70 mg/kg),highest content of available phosphorus (17.36 mg/kg) and better leaf quality;M6 had appropriate content of available nitrogen (63.20 mg/kg),lower root activity and good leaf quality;M7 had appropriate content of available nitrogen (67.03 mg/kg),lower root activity and medium leaf quality.This research indicated that M4,M5 and M6 were the suitable rotation patterns for flue-cured tobacco,M7 (continuous cropping within 2 a) was the next,M1 and M3 were less suitable,and M2 was unsuitable. |
