| 摘 要： | 采用不同的输套作制度及其所产生的稿秆、绿肥等回田并配合施用无机肥料的培肥管理措施,在莆田沿海赤红壤旱地进行两年的小区和示范片的试验,结果表明:两年来土壤有机质增加0.07％—0.38％,全氮含量增加0.01％—0.05％,有机物质的年分解率达38％—76％,有机物质的腐殖化系数为0.1—0.25,土壤有机质的氧化稳定度保持在0.52—0.69。这说明土壤自身的物质和能量已逐渐进入良性的交换循环中,预计按此模式进行培育土壤有机质,在今后的一二十年内土壤有机质可达到2％左右。

| Abstract: | Through the experiments applied the straw and legume crops produced by the different systems of rotation and relay of crops, and applied in company with the inorganic fertilizer, the contents of soil organic matter increased 0.07-0.38% and the nitrogen content increased 0.01—0.05% after two years.The decompound percentage of organic substances was kept an average of 38-76% a year.The humification coefficient of organic substances was 0.1—0.25.The oxidution stability coefficient of soil organic matter was kept up 0.52—0.69.According to this fertilizing, the contents of soil organic matter would increase from 0.86% to 2% in ten or twenty years. |
