本文总结了十多年来对晋中碳酸盐褐土肥力性状及调节途径的试验研究和调查资料,表明肥沃的褐土在理化生物性质和肥力性状上有良好的表现;增施有机肥和深耕可以改善褐土的结构、孔隙、水分、养分,微生物等方面的肥力性状;轮作中的豆科和块茎作物能全面改善褐土的肥力特性,谷类作物也有累积腐殖质的功能;说明通过农业技术措施可以把褐土培育成高产稳产的肥沃农田。
This paper summarizes the experimental research and survey data on the fertility traits and regulatory pathways of carbonate cinnamon soil over ten years in Jinzhong, indicating that the fertile cinnamon soil has good physical and chemical properties and fertility traits. The application of organic manure and Deep-plowing can improve the fertility traits of cinnamon in its structure, porosity, moisture, nutrients and microorganisms. The legumes and tubers in rotation can improve the fertility characteristics of cinnamon soil in general. Cereal crops also accumulate humus. Cinnamon can be cultivated into fertile farmland with high and stable yield.
