摩尔达维亚的苹果短枝型品种,主要是从国外引进的,它们对新环境的适应性极不相同。以前,我们曾指出过苹果生产园中普遍栽植的金冠品种及其短枝型无性系金矮生、黄矮生的某些缺点,其中主要的便是由低温和剧烈的变温所引起的主干伤害。1981～1982年,我们又对摩尔达维亚不同地区的苹果生产园进行了补充调查,旨在弄清伤害性质同坡向、坡位、砧木及树龄的关系。调查结果表明,由低温和变温所引起的苹果短枝型品种植株的伤害程度,
Mold spiders in Moldavia are imported mainly from abroad and their adaptation to the new environment is very different. In the past, we pointed out some of the shortcomings of the golden crown varieties and their spur-type clones, dwarf and golden dwarf commonly planted in the apple production park. The main ones are the trunk injury caused by low temperature and severe temperature change . From 1981 to 1982, we conducted a supplementary survey of apple production areas in different parts of Moldavia in order to find out the relationship between the nature of damage and the aspect, slope position, stock and age. The survey results show that the harm caused by the low temperature and temperature of apple spur type plant injury,
