摘  要：
通过大田试验探讨施用包膜控释掺混肥料(控释BB肥)与普通肥料对土壤养分含量、苹果嫁接苗的生长和经济效益的影响,试验设3个处理,T1为普通肥料处理,N-P2O5-K2O施用量为640-320-480kg/hm2;T2为等量控释BB肥处理;T3为减量控释BB肥处理,施肥量为T1和T2的80%。结果表明,各处理土壤速效养分含量基施后显著上升,至追肥前持续下降;追肥后显著上升,至试验结束持续下降。T2的速效养分含量的变化幅度显著小于T1。控释肥中N的控释率大于P和K,土壤碱解氮含量变化曲线比土壤速效磷、速效钾含量的变化曲线更加平缓。T2的株高、茎粗、壮苗指数、枝条和根的N、P含量高于T1,T3的生长指标总体不低于T1。相对于T1,T2的投入增加23.66%,经济效益增加5.45%;T3的肥料施用量和投入都有所降低,但T1、T3的经济效益差异不显著。从减少肥料的施用量、保护环境和提高经济效益角度考虑,最佳施肥处理为T3。

摘  要：
A field experiment was conducted to study effects of the compound fertilizer blended with controlled release fertilizers and common fertilizers on soil nutrient content, growth and economic benefit of apple nursery stocks. The experiment consisted of three treatment including T1(common fertilizers treatment with 640-320-480 kg / hm2of N-P2 O5-K2 O),T2(equivalent coated controlled blend bulk fertilizer treatment) and T3(decrement coated controlled blend bulk fertilizer treatment with the fertilizer quantity of 80% of T1 and T2). The results showed that the soil available nutrient content increased significantly after basal application and topdressing, and then constantly decreased. In soil the available nutrient content change range of T1 was wider than that of T2. The controlled-released rate of N was higher than that of P and K. The curve of N was more stable than that of P and K. At the same application level, the height, stem diameter, N, P content of plant, seedling index of T2 were significantly higher than that of T1. The application ratio of T3 was lower than that of T1. The growth index of T3 wasn't lower than that of T1. Compared with T1, the input of T2 increased 26.66%, but the economic benefit of T2 increased 5.45%. Compared with T1, the fertilizing aount and input of T3 were lower, but the there was no significant difference in economic benefits between T1 and T3. Considering the decrease of application rate and increase of economic benefit, the optimal treatment was T2.
