‘金红’苹果是黑龙江省当前最优良的苹果主栽品种之一。为了适应果树发展的需要,黑龙江省农垦科学院作物所于1995年建立了‘金红’苹果高接密植栽培试验示范园。试验园设在佳木斯市,年平均气温2.3℃,绝对最低气温-41.1℃,≥10℃积温2 500～2 700℃,无霜期130 d,年降水量550～600 mm。土壤为草甸黑土,pH值7.0,有机质含量2.25%,速效氮75.0 mg/kg,有效磷51.2 mg/kg,速效钾226.7 mg/kg。砧树为山定子,行株距3 m×1.5～2.0 m,即每666.7 m2栽树111～148株。
Golden red apple is currently one of the best apple varieties in Heilongjiang Province. In order to meet the needs of the development of fruit trees, Crops Institute of Heilongjiang Academy of Land Reclamation in 1995 established a ’golden red’ apple high density cultivation demonstration park. The test park is located in Jiamusi City. The annual average temperature is 2.3 ℃, the absolute minimum temperature is -41.1 ℃, the accumulated temperature at ≥10 ℃ is 2 500 ~ 2 700 ℃, the frost-free period is 130 days and the annual precipitation is 550-600 mm. The soil was meadow black soil with pH 7.0, organic matter content 2.25%, available nitrogen 75.0 mg / kg, available phosphorus 51.2 mg / kg and available potassium 226.7 mg / kg. The anvil tree is a mountain stator with a row spacing of 3 m × 1.5 ~ 2.0 m, that is, 111 ~ 148 trees per 666.7 m2.
