茶园的单位面积产量和粗收益,即使在同一地区和相同条件下,也有很大的差异。一般茶园生育不良,是由于气候的影响或病虫灾害以及管理差等不良因子限制,使得茶树根部生长受阻。此时,大多认为土壤排水不良、有效土层浅等等是导致土壤物理条件差的原因。为了摸清茶园土壤与根的生育,我们与茶农在小笠山丘陵一带的圃场茶园,对生育良好与生育差的茶园土进行了调查,现报告如下。 The yield per unit area and crude income of the tea plantations vary greatly even in the same area and under the same conditions. Poor general tea plantation is due to the impact of climate or pests and diseases and poor management and other adverse factors, making the growth of tea roots blocked. At this point, most think that poor soil drainage, effective soil shallow and so on are the reasons leading to poor soil physical conditions. In order to find out the fertility of the soil and root of the tea plantation, we conducted a survey on the tea plantation soil with poor fertility and poor fertility with the tea farmers at the nursery field tea garden in the hills of Mt. Xiaoxu with the following reports.
