该项研究以安徽省沿江棉区的棉花为研究对象,采用“大配方、小调整”策略,研究区域大配方、小调整和缓释配方的应用效果,为棉花简化、节本、高效施肥提供依据。结果表明,从产量上来比较,望江县以大配方处理最优,略优于小调整,东至县则以小调整优于大配方;从效益上分析,棉花专用配方缓控释肥处理最高,小调整次之,随后是大配方处理。因此,大配方小调整更高产,棉花专用配方缓控释肥更高效。
In this study, cotton from the cotton fields in the cotton fields along the Yangtze River in Anhui Province was used as the research object. The strategy of “large formula and small adjustment” was adopted to study the application effect of large formula, small adjustment and slow release formula in the area. Fertilization provide the basis. The results showed that from the output comparison, Wangjiang County to deal with the best formula, slightly better than the small adjustment, the East to the county is better than the small formula to adjust the formula; from the benefit analysis, the cotton formula for controlled release fertilizer the highest , Followed by a small adjustment, followed by a large recipe processing. Therefore, a large formula to adjust the higher yield small, slow-release cotton formulated formula fertilizer more efficient.
