摘要
采用随机区组设计对新型生态螯合肥在水稻上的应用效果进行了研究。结果表明:施用生态螯合肥能明显促进水稻生长,分蘖、SPAD值、叶面积指数、株高、草重和谷重都明显增加;产量和米质性状得到明显提高和改善,表现在穗数、穗粒数和结实率明显增加,糙米率、精米率和整精米率提高,垩白度和蛋白质含量降低;使氮农学利用率明显提高;土壤有机质、全氮和全磷含量增加,10～20 cm土层速效氮、磷、钾含量增加。
The application effects of a new typed eco-chelated fertilizer on rice was studied by using random block design, the results showed that by applying the eco-chelated fertilizer, rice growth was significantly promoted for obvious increase of tillering, SPAD value, leaf area index, plant height, grass weight and grain weight; yield and panicles, grains per panicle, seed setting rate were increased significantly; and rice quality traits were significantly improved, which was appeared in increase of brown rice rate, polished rice rate and fine-polished rice rate, and decrease of chalkiness and protein content; the nitrogen agronomic utilization rate was significantly raised; the soil organic matter, total nitrogen and phosphorus content, available nitrogen, phosphorus, potassium content in the 10-20 cm soil layer were increased.
