在“农业学大寨”运动的推动下,我省各地正在逐步建立油茶“三保”(保水、保土、保肥)地。实践证明,修筑土坡梯地,挖竹节沟,不仅能有效地保蓄水土,在有蜂源的情况下,还能加速油茶授粉蜂的扩散,明显地改善油茶的授粉结实条件,提高着果率,增加茶油产量。 常山林场小茶坪52亩油茶丰产林,每年亩产油都在20斤以上,高产年份可达60余斤 Driven by the “Agriculture Studies in Dazhai” movement, the “three guarantees” (water preservation, soil conservation and fertilizer conservation) of Camellia oil are being gradually established throughout the province. Practice has proved that the construction of slope land, digging bamboo ditch, not only can effectively preserve water and soil, in the case of bee sources, but also to accelerate the spread of Camellia pollinating bees, significantly improve the pollination of Camellia seedling conditions, increased Fruit rate, increase tea production. 52 acres of Camellia Changchai Linchang small rich forest, oil yield per mu in more than 20 pounds, high-yielding years up to 60 pounds
