为解决城乡建设用地增减挂钩引发的宅基地复垦土壤快速熟化问题,试验采用熟化剂、有机肥、粉煤灰三种不同的培肥处理措施,按照不同的组合方案拌成混合生土,对土体进行有机重构。对比试验小区3季粮食产量发现,采用粉煤灰+有机肥处理的平均标准粮产量达7 798.07kg·hm~(-2),位居第一,比位居第二的有机肥处理标准粮产量多855.36kg·hm~(-2)。从土壤快速熟化和粮食产量角度来讲,将粉煤灰+有机肥与生土均匀混合进行土体有机重构作为耕作层,能够有效提高粮食产量,说明粉煤灰有助于加快土壤快速熟化。
In order to solve the problem of rapid maturation of reclaimed soil in homestead caused by the increase or decrease of urban and rural construction land use, three kinds of fertilizing treatment measures such as maturing agent, organic fertilizer and fly ash were tested in this experiment. Mixed raw soil was mixed according to different combinations, Soil organic reconstruction. Comparing the three-season grain yield of experimental plot, it was found that the average standard grain yield with fly ash + organic fertilizer reached 7 798.07kg · hm -2, ranking the first and the second highest than that of the second standard organic fertilizer Yield more 855.36kg · hm ~ (-2). From the point of view of rapid soil ripening and grain yield, the uniform mixing of fly ash + organic fertilizer and raw soil for soil organic reconstruction as tillage layer can effectively increase the grain yield, indicating that fly ash helps to accelerate soil quick-curing .
