脲醛缓释肥质量测定及其在香蕉上的应用研究

Study on urea-formaldehyde slow-release fertilizer and its application on banana

根据"HG/T 4137—2010脲醛缓释肥料"标准对脲醛缓释肥中试产品指标进行了测定,结果表明脲醛缓释肥性能达到并优于该行业标准的指标要求。脲醛缓释肥的机械强度和游离甲醛2项非标准指标可以达到产品的应用要求。在香蕉上的应用研究表明,缓控释肥提高了香蕉的株高、单果重等农艺性状,显著增加香蕉产量,明显减少香蕉施肥次数。

According to the ＂HG/T4137--2010 urea-formaldehyde slow-release fertilizer＂ industry standard, the index of urea formaldehyde slow-release fertilizer pilot products are measured. The results show that the urea- formaldehyde slow-release fertilizer is better than the industry standard and achieves the target requirements. Two non- industrial index of the test products such as mechanical strength and free formaldehyde mass fraction are measured as well. The results show that the mechanical strength and the free formaldehyde fraction of the pilot products can both meet the requirements of application. For banana application, slow release fertilizer improves the banana plant height, weight and other agronomic traits, It also significantly increases the fruit yield and reduce the number of fertilization of banana.
