Abstract:

The incorporation of Chinese milk vetch(Astragalus sinicus L.)represents a green and efficient method for soil fertilization,alleviating soil degradation and environmental pollution caused by long-term chemical fertilizer application. As a traditional cultivation area for Chinese milk vetch,Zhejiang Province lacks a systematic evaluation of the nutrient accumulation characteristics and soil fertility improvement effects of its main cultivated varieties. This study conducted field experiments to compare the yield,nutrient content,and soil fertilization effects of three dominant varieties in Zhejiang Province:Anhui Nanling Yijiang,Jiangxi Yujiang Daye,and Zhejiang Ningbo Daqiao. The results indicated that the Zhejiang Ningbo Daqiao variety exhibited significantly (p<0.05) superior fresh yield and nitrogen and potassium accumulation compared with the other two varieties,demonstrating high biomass production and nutrient efficiency. All varieties significantly enhanced soil organic matter,nitrogen,phosphorus,and potassium content after incorporation,with no significant difference in fertilization effects among varieties. This research provides a scientific basis for the selection and promotion of Chinese milk vetch varieties in Zhejiang Province,offering practical value for reducing chemical fertilizer application,improving soil fertility,and promoting green agricultural development.

Key words: Chinese milk vetch(Astragalus sinicus L.), variety, yield, nutrient accumulation, soil fertilization
