潇河灌区冷性土壤的快速培肥

Study on Fertilizing Soil in Xiao River Irrigation Area

通过潇河灌区冷性土培肥的研究，认为本区潜在肥源──牛奶场厩肥和城市垃圾肥有明显的改土培肥作用，应当充分利用。连续施用，能使土壤物理和化学性质都得到改善，３年平均每亩增产粮食８６１．８～１０９８．４ｋｇ，肥料利润率为３１０．９％～３６０．０％

The study on fertilizing soil in irrigation area showed that manure and garbage compost,which were a continuous fertilizer source,can be used to improve soil physical and chemical properties by succession application.The 3-year total yields raised from 861.8kg/mu to 1098.4kg/mu and the profit rate of the fetilizer was 310.9%-360.0%.
