【摘要】 通过砂、壤、黏3种土壤质地苹果盆栽试验,研究了不同土壤质地对苹果新梢长势、叶片质量、光合特性以及生物产量的影响。结果表明砂土植株新梢长势强旺、壤土中庸、黏土较弱,叶片质量壤土植株优于砂土,砂土优于黏土,光合能力壤土>砂土>黏土植株,总生物产量砂土>壤土>黏土植株,根冠比壤土>黏土>砂土植株,综合分析认为壤土适宜苹果幼树生长,砂土次之。更多还原

【Abstract】 Young apple trees pot-planted in sandy, loam and clay soil were used as materials in the experiment. The growth of shoots, the properties of leaves , photosynthetic capacities and biomass of apple trees were studied. The results were as follows : The length and diameter of the shoots of trees planted in sand were higher than in loam and clay. The leaves of trees planted in loam were thicker and Pn was higher than trees planted in sand and clay. The biomass of trees planted in loam was lower than in sand and was higher than in clay. From all of those we think the loam is suitable for culturing apple trees.更多还原
