近几年我县发展杨梅近百万株,在每年春季嫁接后种下,已经长出新梢,但一到秋季却死掉50％左右,几年后还出现陆续死亡。这是什么原因呢?根据岩头林业站调查鉴定,死幼株的主要原因是嫁接后包扎物的关系。
In recent years, our county has developed nearly one million Yangmei plants and planted them after grafting in the spring of each year. However, they have already produced new shoots in the spring, but they die about 50% in the fall but have died in succession in a few years. What is the reason? According to Yantou forestry station investigation and identification, the main reason for dead young plants is the grafting after grafting relationship.
