摘  要：
为了选择新垦红壤熟化的适宜方法,以新垦红壤旱耕地为对象,当地旱地习惯经营为对照,采用田间大区对比试验,研究了种植绿肥翻埋、深耕+施有机肥、象草茎叶易地还田、配方施肥等熟化方法对新垦红壤的熟化效应。结果表明:各熟化方法实施3 a后的熟化效应明显,较对照年径流深减少8.1%~45.1%、年泥沙流失量减少12.1%~58.1%;水稳性大团聚体总量均高,尤其0.5~1.0 mm粒级的水稳性团聚体含量显著高;耕层有机质含量提高了3.9%~19.6%,除配方施肥处理外,其他3个处理极显著提高;玉米增产22.7~58.6 kg/667m2,增产7.3%~18.7%,差异分别达显著和极显著水平;产投比由1.75提高到2.20,提高25.7%。

摘  要：
In order to select a proper way to cure the newly reclaimed red soil, this study has been conducted to test the curing effects of ploughing in grown green manure, deep tillage with organic fertilizer use, elephant grass returning to field ex situ and the formula fertilization on newly reclaimed red upland soil with the local upland conventional management as the control and by field regional contrast. The results indicate that the curing effects of the different curing methods practised for 3 years have been significant, the annual runoff has been decreased by 8.1%~45.1% and the annual sediment loss has been reduced by 12.1%~58.1%, compared with the control. The amount of soil water-stable macro-aggregate has been high, especially the 0.5~1.0mm-level soil water-stable macro-aggregate. The organic matter content in the arable layer has been increased by 3.9%~19.6% significantly with the other 3 treatments except the formula fertilizer treatment. The corn yield has increased by 22.7~58.6 kg per 667m2, up 7.3%~18.7%, significantly or more. The input-output ratio has increased by 25.7% from 1.75 to 2.20.
