(续上期)翌日上午,杨师傅驾驶摩托车送我回蜂场,他说走公路顺便到常山镇买几把镰刀准备秋收。这是一条吉林通往桦甸的交通要道,车流量很大。快到常山镇时我们看到公路边有一处蜂场,蜂箱在场地上围成四方形排列,一顶深绿色的帐篷支搭在场地边上,帐篷前边的两只蜂箱上摆满装好蜂蜜的瓶子。我示意杨师傅停车过去拜访一下,于是,我们便把摩托车停靠在蜂场边上。 相似文献

A research was conducted to assess the effects of three different drying techniques, namely open sun drying (OSD), solar dryers (SD) and solar tent dryers (STD). Data on physical characteristics such as weight, total length and standard length were recorded and proximate composition of the fish sample Clarias gariepinus (Burchell, 1822) was carried out before, during and after drying to assess changes on physical characteristics and nutrient composition at different level. After drying, the samples were subjected to storage for eight weeks. The result obtained shows that there was no significant (P 〉 0.01) difference in the drying weight of the fish samples between the direct SD and the STD. However, for the total and standard length there was significant (P 〈 0.01) difference in the drying techniques, but no significant difference (P 〉 0.05) in the drying period. There was no significant (P 〉 0.05) difference on the physical parameters, storage period, proximate composition of both direct SD and STD and the drying period, respectively. Therefore, direct SD can be substituted with the STD without altering the quality of the product. 相似文献
