本研究于1974～1977年进行有:1.丘陵红壤修筑“等宽”梯田,坡度宜在3～8度范围较为理想。坡度3～4度的地段,可开成4.6～9米的“等宽”梯田,种茶3～6行。坡度较大,梯田可适当缩窄,结合茶园道路、沤格和水沟,直线和弧线两种梯田可同时并用。2.1975年春,600余亩“等宽”梯田,移栽了一年生福鼎大白茶扦插苗,三年后的茶树,树高平均89.9厘米,树幅87.5厘米,复盖度达58.3%,78年春夏茶打顶采,亩产干茶达80余
The research carried out in 1974 ~ 1977: 1. Hilly red soil to build “wide ” terraces, the slope should be in the range of 3 to 8 degrees is more ideal. The slope of 3 to 4 degrees of the lot, can be opened into 4.6 ~ 9 meters “width ” terraced fields, tea 3 to 6 lines. Slope larger terraces may be narrowed, combined with the tea garden roads, Su grid and ditches, straight and arc terraces can be used simultaneously. In the spring of 1975, more than 600 mu of “equal width” terraces were transplanted with the annual Fuding white tea cuttings. Three years later, the tea trees had an average tree height of 89.9 cm and a width of 87.5 cm with coverage of 58.3% and 78 Spring and summer tea topping mining, dry tea yield more than 80 mu
