我所于1953年—67年通过试验示范和调查研究,查明了茶园低产成因,总结提出行之有效的“三改一补”和肥、管、养、剪、采、保相结合的综合技术。本所通过小面积低产茶园试验,改低产(亩产50—60斤)为高产,创造1.007亩福安菜茶七年平均亩产418.7斤,33亩亩产干茶350—380斤的丰产水平。试验表明:1.茶园跑水跑肥是土壤贫脊的主要原因,提出因地制宜采用石头、草砖、夯埂等方法,构筑梯埂,改不等高为等高梯层,改内高外低为内低外高,改纵沟纵路为内壁横沟蓄水与环山缓坡路等。2.茶树根系试验,明确粗老侧根有更新 Through the demonstration and investigation in 1953-67, I identified the causes of the low yield of tea plantations and concluded that the effective combination of “three reforms and one supplement” and the combination of fertilizer, pipe, raising, cutting, picking and protecting The comprehensive technology. The small-scale low-yield tea plantation trial, change low yield (50-60 kg per mu) for high yield, create 1.007 mu Fuan tea seven years average yield of 418.7 kg, 33 acres of dry tea 350-380 pounds of high yield level. The results showed that: (1) Runing water from the tea plantation was the main reason of soil ridges, and put forward the method of using stone, grass brick and ramming 因 according to local conditions to build the ladder 埂, For the low outside high, change the vertical groove longitudinal groove wall water storage and mountain slope ramp and so on. 2. Tea root test, clear the old side of the root has updated
