为了提高富士苹果的单位面积产量和促进幼树早期丰产,我们从1974年起,建立了不同矮化中间砧的栽培试验区,调查了富士苹果嫁接在 M 系矮化中间砧上的矮化效果,生长表现,结果早晚,丰产性能及其矮化栽培技术,现将八年的调查结果总结如下:一、富士苹果嫁接在 M 系中间砧上的生育表现(一)试材及方法试验区设在所内平地上,土层较厚,土壤肥力中等,土壤有机质含量,0～20厘米为1.36%、20～40厘米为1.01%;全氮含量分别为0.001%、0.07%;全磷含量分别为0.116%、0.08%;有效钾每百克土壤中含量分别为11.5毫克、12.5毫克;pH 值为5.3～6.5。1971年到
In order to improve the yield per unit area of Fuji apple and to promote the early seedling yield of saplings, we set up the cultivation experiment area of different dwarfing anvil from 1974 onwards and investigated the dwarfing effect of Fuji apple grafted onto the M-series dwarfing anvil , Growth performance, the results sooner or later, high yield performance and its dwarfing cultivation techniques, the findings of the eight-year survey are summarized as follows: First, the Fuji apple grafted on the M system on the anvil fertility performance (A) The content of soil organic matter was 1.36% for 0-20 cm and 1.01% for 20-40 cm. The content of total nitrogen was 0.001% and 0.07% respectively. The content of total phosphorus was 0.116%, 0.08%; available potassium content per hectare soil was 11.5 mg, 12.5 mg; pH value of 5 3 ~ 6 5 1971 to
