有机复合肥在沿淮水稻上的肥效研究

Study on Fertilizer Efficiency of Organic Compound Fertilizer on Rice in the Region along Huaihe River

在沿淮黄潮土上 ,采用随机区组法对几个复合 (混 )肥品种在水稻上的肥效进行了比较试验。结果表明 ,有机复合肥对水稻的生长发育、分蘖的发生、有效穗数的增加和产量的提高都有良好的促进作用 ,增产、增收效果明显。因此 ,从提高作物产量和效益的角度出发 ,应加大有机复合肥的推广应用 ,同时也可起到改良、培肥土壤的作用。

Adopting randomized blocks design, the fertilizer efficiency of several types compound-fertilizer were tested in fluvo-aquic soil in the region along Huaihe river. The results showed that organic compound-fertilizer had a good acceleration function on rice growth, tillering, effective spike and paddy yield.So, its effect on increasing yields and incomes was the best among several types compound fertilizer , the second-best effect were three-kind-element and two-kind-element inorganic compound fertilizer. Therefore, setting up from point of view to increase crop yields and incomes, the compound fertilizer, especially organic compound fertilizer, should be extended, and the recommendation was persisted in long terms, the soil could be meliorated, and soil fertility could be enhanced.
