1977年元月底,我县近万亩温州蜜柑遭受周期性冻害,最低气温达到-10.9℃。由于地势、品种和培管水平等不同因素的影响,受冻程度有所不同,大致分三种情况。近两年来,各地干部和群众针对不同受冻情况采取了不同的技术措施,加快恢复了树势,受冻较轻的树已经获得了增产。一种是受冻轻微,柑桔树部分落叶。我县洈水库区种植的柑桔树由于受水系影响,受冻落叶30—40％。这种受冻树的树体营养虽受到一定损失,但还保存相当一部分叶片,因而还能进行比较正常的生理功能,容易恢复树势。对这类受冻树应要求当年树势复壮,
By the end of January 1977, nearly ten thousand acres of Wenzhou Satsuma suffered periodic frost damage, the minimum temperature reached -10.9 ℃. Due to the influence of different factors such as topography, variety and training level, the degree of frostbite is different. There are roughly three kinds of situations. In the past two years, cadres and the masses all over the country have adopted different technical measures in response to different situations of frostbite, accelerated the recovery of the tree vigor, and the tree with less frost has gained production. One is slightly affected by the cold, orange tree part of the leaves. Mianzhu reservoir area of my county planted citrus trees due to the influence of the waterways, by the frozen leaves 30-40%. Although the tree body of the frozen tree suffered a certain loss, but also save a considerable part of the leaves, which can also be more normal physiological functions, easy to restore the tree vigor. This type of frozen trees should be rejuvenated at that time,
