摘要
[目的]研究了控释BB肥对苹果嫁接苗生长和经济效益的影响。[方法]通过大田试验,比较控释BB肥与普通肥料的施用效果。[结果]施肥量相同的SF与CRF1处理相比较,CRF1处理嫁接苗质量、经济效益在0.05水平显著高于SF处理;即使减少肥料的施用量,CRF2、CRF3处理嫁接苗质量和经济效益仍不低于SF处理。因此,从培育优良的苹果嫁接苗的角度考虑,控释肥推荐施肥量为630-150-480 kg/hm2;从减少肥料投入、增加经济效益的角度考虑,控释肥推荐施肥量为504-120-384 kg/hm2。[结论]该研究可为控释肥在苹果苗圃育苗上的合理施用提供技术指导。
[Objective] The aim was to study the effects of the compound fertilizer blended with controlled release fertilizers and common fertilizers on growth and economic benefits of apple nursery stocks.[Method] Through field experiments,the effects of controlled release blend bulk fertilizers and common fertilizers were compared.[Result] SF treatment and CRF1 treatment with the same fertilizing amount were compared,the results showed that the growth and economic benefits of CRF1 treatmentwere better than that of SF treatment at 0.05 level,even the application rate of CRF2 and CRF3 treatment was lower than that of SF treatment,but the growth and economic benefit weren＇t lower.Therefore,considering from the cultivation of good apple nursery stocks,the application rate of fertilizers was recommended as 630-150-480 kg/hm2.But considering from the decrease of application rate and the increase of economic benefits,the application rate of fertilizers was recommended as 504-120-384 kg/hm2.[Conclusion] The study provided technical advice for applying controlled release fertilizers on apple seedling culture.
