为促进脲醛缓释肥在小麦种植上的推广应用,对不同配比的脲醛缓释肥与普通复合肥进行了肥效试验。试验结果表明:脲醛缓释肥比普通复合肥增产效果明显,增产幅度在1.8%~6.5%;脲醛缓释肥可提高小麦的有效穗数,亩经济效益增幅在35.3~59.0元;在脲醛缓释肥施用量减少20%的条件下,仍能保持小麦稳产,取得了最佳的种植收益。
In order to promote popularization and application of urea-formaldehyde slow-release fertilizer in wheat planting, fertilizer efficiency experiments of urea-formaldehyde slow-release fertilizer with different proportions and common compound fertilizer are carried out. Experimental results show that yield-increasing effect of urea-formaldehyde slow-release fertilizer is more obvious than that of common compound fertilizer, yield increases by 1.8% to 6.5%; urea-formaldehyde slow-release fertilizer can increase effective panicles of wheat, economic benefit increases by 35.3 to 59.0 yuan per mu; under conditions that use of urea-formaldehyde slow-release fertilizer reduces by 20%, wheat yield still can be kept stable, achieving the best planting income.
