锯末轻而疏松,表面积大,吸溼性强,透气性高,兼有杀菌防腐、隔绝毛管等作用,在农业生产有多方面的应用价值。 首先,锯末作为果树、林木种子的貯藏介质,于秋冬期间拌溼后与种子层积貯藏,比用河砂层积貯藏的种子萌动期早、萌动率高,管理又方便。用锯末填入葡萄、杨柳等插条中,进行催根处理,也比填砂发根早、发根率高,效果好。因为插条或种子,在层积催芽、催根过程中,都要求溼润、透气、适温三个条件,锯末表面积最大而不规则,吸溼力大,透气性强,加上人工控制适温,正可充分满足层积催根的需要。
Light and loose sawdust, large surface area, hygroscopicity, high permeability, both bactericidal anti-corrosion, isolation capillary and so on, in the agricultural production in many aspects of the application value. First of all, sawdust as a fruit tree, tree seed storage medium during the autumn and winter mixed with the seed storage after storage than sand stratified storage seed germination early, high germination rate, management and convenient. Use sawdust to fill in grapes, willow and other cuttings for rooting treatment, but also than the early filling sand, hair root rate, the effect is good. Because the cuttings or seeds, in the stratification of germination, the process of rooting, require wetting, breathable, suitable temperature three conditions, the largest and irregular sawdust surface area, high moisture absorption, permeability, coupled with manual control Temperature, can fully meet the needs of the stratification of the root cause.
