摘要:

紫云英还田是一种绿色高效的耕地培肥方式,可缓解长期化肥施用导致的土壤退化和环境污染问题。浙江省作为紫云英传统种植区,其主栽品种的养分积累特征与土壤培肥效应尚缺乏系统评估。本研究通过田间试验比较了安徽南陵弋江种、江西余江大叶种和浙江宁波大桥种这3个浙江省主栽紫云英品种的产量、养分含量及还田后的土壤培肥效应。结果表明,浙江宁波大桥种在鲜草产量和全氮、全钾积累量方面显著(p<0.05)优于另两个品种,表现出较高的生物量与养分高效性。各品种还田后均能显著提高土壤有机质、全氮、有效磷、速效钾含量,且品种间的培肥效果一致。本研究为浙江省紫云英品种优选与推广提供了科学依据,对促进化肥减量、地力提升和农业绿色发展具有重要实践价值。

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
