对1985年冬—1986年春发生在河北省石家庄地区的桃树冻害进行了系统的调查,结果看出,各品种因冻害引起的僵芽率平均达91.3％;平均减产65％以上;雪桃冻死植株几乎100％。冻害有明显的高低层次分布和区域性分布。冻害对树干加粗生长无明显影响,对伸长生长有一定的抑制作用,受冻后果实普遍增大。对冻害的主要原因进行了气象分析。
A systematic investigation was conducted on the pest frost damage in Shijiazhuang, Hebei Province in the winter of 1985 to the spring of 1986. The results showed that the rate of normal shoots caused by frostbite was 91.3% on average, and the average yield was reduced by 65% Dead plants are almost 100%. Frost damage has obvious level distribution and regional distribution. Frost damage has no obvious effect on bold growth of stems, has a certain inhibitory effect on elongation growth, and generally increases after frozen. Weather analysis of the main causes of frost damage.
