防护林能否预防果树冻害问题,已引起了一些同志们的兴趣,在《新疆农业科学》上发表文章进行讨论.对拙著中“预防苹果冻害的有效措施,是在果园四周建造防护林”的论点,提出了不少宝贵意见.细读各篇论文之后,可以归纳出三点:第一,“防护林有一定的小气候效应”.(李江风、肖克东、林培钧三同志)第二,“它(防护林)的防冻效应是很难肯定的”.(肖克东、林培钧二同志)第三,“防护林并非毫无防冻作用”(李江风同志). The issue of whether shelterbelt can prevent fruit frost damage has aroused the interest of some comrades and published an article in “Xinjiang Agricultural Sciences.” In my book, “the effective measure to prevent apple frost damage is to construct shelterbelts around the orchard” (Li Jiangfeng, Shock East, Lin Peijun three comrades) Second, “it (shelterbelts) is the most important part of the protection of forests, (Xiao Kendong, Lin Peijun two comrades) Third, ”shelter forest is not without antifreeze" (Comrade Li Jiangfeng).
