摘要
以新疆进行冬小麦套种草木樨县（市）为调查对象，整理其作物产量及土壤指标变化，综合指标分析经济生态效益，为大面积推行提供直观效益依据。结果表明冬小麦套种草木樨每亩增加纯收益1263元；土壤有机质含量提高2．33g／kg，碱解氮含量提高14．4mg／kg，速效磷含量提高3．31mg／kg，土壤容重降低0．06g／cm^3。土壤全氮增加32％~41％，有机质增加41％-84％，土壤肥力大幅度提高，土壤物理结构得到有效改善。
Winter wheat interplanting sweet clover in Xinjiang county （city） as the investigation object, Finishing changes of yield and soil index of the crop, Ecological economic benefit analysis of comprehensive index, Provide direct benefits according to carry out large area. The results showed that winter wheat interplanting sweet clover increased net income 1 263 yuan per mu; Organic matter content of the soil increased 2.33 g/kg, Alkali hydrolyzable nitrogen content increased 14.4 mg/kg,Available phosphorus content increased 3.31 mg/kg, The soil bulk density decreased 0.06 g/cm3, soil total nitrogen increased 32%-41%, organicmatter increased 41%-84%,Soil fertility greatly improved, To be effective in improving soil physical structure.
