在当前茶园肥水管理中,叶面追肥及喷施植物生长调节剂是一项增产的重要措施。本试验旨在探讨新型、特效复合植物生长调节剂“叶面宝”对茶叶的增产效应。 1.试验情况 本试验在我县昌付茶场1974年种植的一块4.6亩群体茶园进行。供试叶面宝是广西博白县沙河叶面宝厂生产的。试验处理设:①叶面宝1支(5毫升)+水80斤(12.5ppm);②叶面宝1支+水80斤+0.6％尿素+0.4％磷酸二氢钾;③喷清水(对照)三个处理。重复三次,小区随机排列。同一重复内各小区茶蓬生长均匀一致,小区面积为10.5m~2。于1987年春茶
In the current fertilizer and water management of tea plantations, foliar topdressing and spraying of plant growth regulators are an important measure to increase production. The purpose of this study is to explore the new type of special compound plant growth regulator “foliar” on tea yield. 1. Test situation This experiment was carried out in Changpu Tea Plantation County in 1974 with a 4.6-acre tea plantation. Test leaves for the treasure is Bobai County, Guangxi Shahe Ye surface of the factory production. The experimental treatment set: ① foliar treasure 1 (5 ml) + water 80 pounds (12.5ppm); ② foliar treasure 1 + water 80 pounds + 0.6% urea + 0.4% potassium dihydrogen phosphate; ③ spray water Three processing. Repeated three times, the district randomly arranged. The same repeat within the community tea growth uniform, cell area of 10.5m ~ 2. In the spring of 1987
