The Impact of Green Manure Intercropping on the Yield,Quality of Citrus Pomelo and Soil Fertility
摘要
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.关键词
