【摘要】 试验研究不同温度对APEX园艺专用控释肥料养分释放特性的影响结果表明,3种控释肥料释放速度均受温度的影响,且随温度的升高而释放速度加快,释放周期相应缩短,但3者对温度的敏感性不同,常绿植物肥尤其是P、K易受温度的影响,木本植物肥释放速度受影响最小,其养分释放也很平稳,控释效果最佳。更多还原

【Abstract】 The effects of different temperatures on the nutrient releasing characters of APEX horticultural release-controlled fertilizer were studied.The results show that the release ratios of three kinds of release-controlled fertilizer are affected by the temperature,and with the temperature rising,the release ratio is promoted,the release cycle is shortened,and the sensitivities of three release-controlled fertilizers on temperature are different,the evergreen plant fertilizers,expecially P and K are easily affected by temperature,the release ratio of tree plant fertilizers is affected little by temperature,its release is stable and the controlled efficiency is the best.更多还原
