1984年秋和85年春,我县栽植苹果、梨半成苗6万余株,成活率大部分在80%以上。通过实践,我们认为,定植半成苗必须抓好以下技术措施:一、挖大坑,换熟土,施底肥。不能认为半成苗小就挖小坑。栽后在接芽以上1厘米处剪砧埋土。4月25日以后将埋土取至砧顶,接芽仍在土中,5月初接芽大部发芽抽枝。二、及时提供肥水。在干旱的季 The autumn of 1984 and the spring of 85, my county planted apples, pear semi-mature more than 60000 strains, most of the survival rate of more than 80%. Through practice, we believe that planting semi-mature seedlings must grasp the following technical measures: First, digging pit, soil replacement, base fertilizer. Can not think half a small seedlings to dig pits. After planting in the bud 1 cm above the cut anvil buried. After April 25 will be buried to the top of the anvil, then the bud is still in the soil, early bud bud sprouting in most of May. Second, provide timely fertilizer. During the arid season
