摘要：

为筛选适宜建瓯市桔柚园的绿肥套种模式，探究不同绿肥对桔柚产量、品质及土壤肥力的调控效应，本研究以7年生桔柚园为试验对象，设置清耕对照(T1)及套种箭筈豌豆(Vicia sativa)(T2)、苕子(Vicia dasycarpa)(T3)、紫云英(Astragalus sinicus)(T4)、油菜(Brassica napus)(T5)、紫花苜蓿(Medicago sativa)(T6)、羽扇豆(Lupinus micranthus)(T7)6种绿肥处理，系统测定不同处理下桔柚果实农艺性状、产量、品质及土壤理化性质。结果表明，与清耕相比，绿肥套种的6种处理可使果实产量显著提高，产量增加951.0~3001.5 kg/hm2，增幅5.06%~15.98%，其中套种箭筈豌豆和紫云英的增产效果最好。套种绿肥能提高果实维生素C、可溶性固形物、还原糖、可滴定酸含量和糖酸比，降低硝酸盐含量24.71%~50.57%。同等条件下套种苕子、紫云英、油菜能获得更高的绿肥鲜草产量。与清耕相比，套种绿肥可提高土壤有机质含量5.96%~14.04%、全氮含量2.58%~12.90%、碱解氮含量9.79%~21.39%、有效磷含量13.28%~21.40%和速效钾含量16.84%~32.63%，其中套种箭筈豌豆土壤培肥效果最好，其次为光叶苕子和紫云英。综上所述，桔柚园套种绿肥可实现增产、提质、培肥协同效应，箭筈豌豆综合表现最优，可作为当地桔柚园绿色栽培的优选模式推广应用。

Abstract:

To screen suitable models of green manure intercropping for citrus orchard in Jian'ou City, and explore regulatory effects of different green manures of citruspomelo and soil fertility, the 7-year-old citrus orchard was selected as the experimental subject, the clean cultivation (T1) was used as control, and the interplant Vicia sativa (T2), Vicia dasycarpa (T3), Astragalus sinicus (T4), Brassica napus (T5), Medicago sativa (T6), and Lupinus micranthus (T7) were served as the six experimental treatments, the impact of the different treatments on citrus fruit agronomic trait, yield, quality, and soil physicochemical property were systematically analyzed in this study. The results showed that the six interplant treatments significantly increased citrus yield by 951.0-3001.5 kg/hm2, with the increasing ratio of 5.06%-15.98%, when compared with clean cultivation. Among these, interplant Vicia sativa and Astragalus sinicus achieved the best yield improvement. The interplant green manures enhanced the content of vitamin C, soluble solid matters, reducing sugars, titratable acids, and the sugar-acid ratio, reducing nitrate content by 24.71%-50.57% in the fruit. The interplant Vicia dasycarpa, Astragalus sinicus and Brassica napus obtained higher fresh grass yields under the same conditions. Compared to clean cultivation, interplant green manures increased the content of soil organic materials by 5.96%-14.04%, total nitrogen by 2.58%-12.90%, alkeline-N by 9.79%-21.39%, available phosphorus by 13.28%-21.40%, and available potassium by 16.84%-32.63%. Among these, interplant Vicia sativa obtained the best improvement of soil fertility, followed by Vicia dasycarpa and Astragalus sinicus. In conclusion, interplant green manures in citrus orchard acquire synergistic effects on yield enhancement, quality increasing, and soil fertility improvement. The interplant Vicia sativa exhibits the most comprehensive effectiveness, and could be promoted and applied as the preference pattern of green cultivation in local citrus orchards.
