多点定位田间试验表明．在福建中低产红壤稻田中混合施用有机和无机肥料，可使水稻生产效率在短期内得到稳定增长（３０％－９２％）．经统计分析比较，水稻生产效率与有机无机总养分（或总氮）投入量呈极显著相关；有机无机肥结合的优点主要表现在土壤生产力的稳定积累和元素生产效率的提高．参试的４大有机给源配合半量化肥的作用近于等效，但在试验期限内（１－３ａ），稻谷产量无额外的互作效应，而绿肥鲜体在增产养地配合效应上具有明显的优势． Multi-point field test shows. The mixed application of organic and inorganic fertilizers in middle and low yielding paddy red soils in paddy fields in Fujian could increase the rice production efficiency steadily (30% -92%) in a short period of time. Through statistical analysis and comparison, the rice production efficiency was significantly and significantly related to the total input of organic and inorganic nutrients (or total nitrogen); the advantages of combining organic and inorganic fertilizers were mainly manifested in the steady accumulation of soil productivity and the improvement of the production efficiency of the elements. The effect of the four organic sources with semi-fertilizer was nearly equivalent, but there was no additional interaction effect during the test period (1-3a), while the fresh green manure had the same effect obvious advantage.
