茶园深耕时期有七金八银的农谚,但是缺乏理论依据,因此,本试验旨在通过茶园不同深耕时期的研究,探明其对茶树的生长,茶叶产量,茶园土壤理化性质的影响,为确定本场今后茶园深耕时期提供理论依据。供试茶园及处理方法 (一)供试茶园。本试验于1987年设在双峰茶场二队,品种系江华苦茶,1981年春用种子直播,土壤为红壤,肥力一般,pH值4.5～5.5之间,丘陵坡地,换种改植茶园。 (二)处理方法。试验茶园伏耕、秋耕两个不同时期和不耕为对照的处理,两次重 Therefore, this study aimed to study the effects of tea plantation growth, tea yield and physical and chemical properties of tea plantations on the basis of researches on tea plantation in different deep plowing periods. In order to determine The field of tea plantation in the future to provide a theoretical basis. Test tea garden and treatment methods (A) for the test tea garden. This experiment was set up in 1987 in Shuangfeng Chachang two teams, the varieties of tea Jiang Kucha, the spring of 1981 direct seeding, the soil is red soil, fertility, pH 4.5 to 5.5, hilly slopes, replanting planting tea. (B) approach. Flue-curing tillage tea, autumn plowing two different periods and non-tillage control treatment, twice heavy
