四川省东印茶场位于川东大巴山余脉,数以千亩云雾缭绕、鳞次栉比梯型茶园,都是五六十年代垦荒种植的川茶中叶群体种。近年来,我们调查在相同条件下,陡坡园与缓坡园,亩产悬殊,且肥培水平逐年提高,两者单产差距日趋显著。大量陡坡园的存在,已成为我场生产经营的“包袱”,类似这类“拉腿园、包袱园”在川东产茶乡村屡见不鲜。为探索陡坡园低产原因及其改造,笔者曾对陡、缓坡园差异作过追踪调查。现就调查资料整理如下: 一、陡坡园与缓坡园的差异这里所讲的陡坡园是指地面坡度≥30°,梯面宽度≤1.35米的茶园;缓坡园是地面坡度≤15°,梯面宽度≥l.65米的茶园。我场1981—1985年连续5年调查,陡坡园亩平鲜叶111.18公斤,只及缓坡园亩平369.56公
Sichuan Province, East India Tea Plantation is located in Daba Mountains in Sichuan Province, the remaining veins, thousands of acres of mist-filled clouds, row upon row of ladder-type tea plantations, are fifties and sixties reclamation planted middle-aged group of Sichuan tea. In recent years, we investigated under the same conditions, steep slope and gentle slope park, per-mu yield disparity, and the level of fattening peasants increased year by year, the yield gap between the two increasingly significant. The existence of a large number of steep slope park, has become my field production and management of “baggage”, similar to this type of “legged leg park, burden of garden” tea plantations in eastern Sichuan is not uncommon. In order to explore the reasons for the low yield of steep slope garden and its transformation, the author made a follow-up investigation on the difference between steep slope and gentle slope garden. The survey data are summarized as follows: First, the differences between steep slope and gentle slope Park Steep slope here refers to the ground slope ≥ 30 °, the width of the ladder ≤ 1.35 meters of the tea plantation; slope slope is the slope of the ground ≤ 15 °, the surface Width ≥ l.65 meters of the tea garden. My field 1981-1985 for five consecutive years of investigation, steep slope Park acres of flat leaves 111.18 kg, and gentle slope Park only 369.56 acres of public
