乌桕的种子外面包被一层白色的蜡层妨碍水分的浸透,影响种子的发芽,尤其是蜡层厚的品种,播种前如果不把它去掉,不但发芽慢而且会降低发芽率。过去,我们常用80℃温水浸种24小时后,再在石臼中捣去蜡层。这种方法,劳动强度大,效率低,每人每天只能处理40多斤种子,同时蜡层还脱不干净。近年来,我们用机械处理乌桕种子,具有以下优点:(1)减轻了劳动强度,提高了工效,而且脱蜡干净,1小时可处理种子200余斤;(2)可以充分利用蜡 The black walnut seeds are covered with a layer of white wax to prevent the penetration of water and affect the germination of the seeds, especially the waxy layer. If they are not removed before sowing, they will not only germinate slowly but also reduce the germination rate. In the past, we often soaked in warm water at 80 ℃ for 24 hours, then smashed in the mortar wax layer. This method, labor-intensive, low efficiency, each person can handle only 40 kilos of seeds per day, at the same time the wax layer is also off not clean. In recent years, we use the mechanical treatment of the seeds of Opuntia angustifolia, has the following advantages: (1) to reduce the labor intensity and improve the work efficiency, and dewaxing clean, an hour can handle more than 200 pounds of seeds; (2) can make full use of wax
