摘　　要：通过在三江平原低湿耕地白浆土上玉米的微区试验,细致地研究了不同肥田垄对玉米生长发育及产量的影响。试验结果表明:采取深松、耙茬、秸秆还田、增施有机肥等措施建造肥田垄,对改良土壤结构,改善土壤的耕性,增强白浆土的抗旱防涝能力,以及对调节土壤保肥、供肥能力均具有明显效果,可显著提高低湿白浆土玉米的产量。Through the microplot experiment on spring corn in low and wet cultivating land in Albic soil in San Jiang plain, the effects on spring corn抯 growing and output in different fertile land were studied in detail. The results of experiment showed that the deep loosening measure could obviously enhance the ability to fight against drought and waterlog in Albic soil. It had obvious effect to improve the ploughed quality of soil. Stubble of harrowing, returning straw to the soil and adding the fertilizer had great effect in adjusting soil intensity. Thus it will increase the output of corn in damp ploughed soil.
