一、冻害情况我场于八○年三月在场部建立一片面积为18.5亩的福云七号试验园。采用双行双株条植法,规格为大行距90厘米,小行距40厘米,丛距40厘米,每亩种植茶苗5100株。定植前做了比较充分的准备工作,茶苗定植后,固定专人精心管理,八○年秋天茶苗长势茁壮,平均植高43厘米,出现2—5条骨干枝。但是,定苗后两年来,冬季均遭受不同程度冻害。据我场与福安农校部分师生调查结果,主茎冻伤茶树占总株数的42—50％,冻害后死亡的茶苗占
I. Frost damage The field set up a site of 18.5 mu in Fuyao No.7 Test Ground at the scene in March 1980. Using double lines of double-stranded plant law, specifications for the big row spacing 90 cm, 40 cm small row, 40 cm cluster distance, planted tea seedlings per acre 5100. Pre-planting done more fully prepared, tea seedlings colonization, the careful management of the fixed person, in the fall of 2008 tea seedlings grow strong, the average planting height of 43 cm, there 2-5 branches of the backbone.
