我场现有茶园3755亩,缺株断垄的面积占15～20％,其中严重缺株的达30％以上。虽经多年用种子直播和移苗补植,不是出苗率低,成活率差,就是幼苗夭折,少数勉强成活,也是既矮又瘦。因此,迅速改变茶园残缺面貌,提高茶叶单产,是我场当前茶叶生产上迫切要求解决的问题。为此,我们学习了棉花、瓜菜、烟草等作物利用营养钵育苗的方法,于1965 My field now has 3755 acres of tea plantations, covering 50% to 20% of the total area, of which 30% are severely impacted. Although after many years of direct seeding and replanting seedlings, not the emergence rate is low, the survival rate is poor, that is, seedlings die, a few barely survive, but also short and thin. Therefore, to rapidly change the incomplete face of tea plantations and increase the yield of tea leaves is an urgent issue to be solved in the current tea production in our field. To this end, we have studied cotton, vegetables, tobacco and other crops using nutrient seedling breeding methods, in 1965
