1970～1984年在季米里亚捷夫农学院《米哈洛夫》试验基地进行了试验,试材为接于安托诺夫卡实生苗上的普通安托诺夫卡,1970年定植。果园土壤为生草灰化中性壤土。耕层腐植质含量2.8％,P_2O_5为3.0毫克/100克土,K_2O为11.0～13.5毫克/100克土。土壤pH=5.4,吸收性盐基饱和度为81.6％。试验方案:处理1:每年施N_(60)P_(90)K_(60);处理2:每年施N_(180)P_(90)K_(60);处理3:每年施N_(60)+5年1次P_(450);K_(300);处理4:每
1970 to 1984 at the Jekyllback Agricultural College “Mikhailov” test base was tested, the sample is connected to Antonovka seedlings ordinary Antonovka, 1970 planting. Orchard soil for the grass ashes of neutral loam. Soil humus content was 2.8%, P_2O_5 was 3.0 mg / 100 g soil, K_2O was 11.0 ~ 13.5 mg / 100 g soil. Soil pH = 5.4, absorbent base saturation was 81.6%. Test plan: Treatment 1: N_ (60) P_ (90) K_ (60) applied annually; Treatment 2: N_ (180) P_ (90) K_ (60) applied annually; Treatment 3: Year 1 P_ (450); K_ (300); Treatment 4: Each
