油松林用保水剂包衣种子飞播造林试验结果表明 :SA - 10 5型林用保水剂不仅具有超高吸水能力和保水能力 ,而且可反复吸收释放水分有效保墒蓄水。在小坡林场 ,667m2 内包衣种子出苗 2 1株 ,未包衣种子出苗 9株 ,前者为后者的 2 34倍 ;在西李背村 ,12 0m2 内包衣种子出苗 12株 ,未包衣种子出苗 8株 ,前者为后者的 1 5倍。均有显著提高出苗率的效果 The experiment results of aerial seeding and afforestation on seedlings of Pinus tabulaeformis forest with SA showed that SA - 10 5 forest water retaining agent not only has the ability of super high water absorption and water retention, but also can absorb and release water repeatedly to effectively conserve water. In Xiaopo forest farm, 21 out of 667m2 seeds were inoculated and 9 of the uncoated seeds were emerged, the former was 234 times of the latter. In Xi’liu village, 120 seeds were inoculated in 120m2, uncoated seeds 8 plants emerge, the former is 15 times of the latter. All have significantly increased the effect of germination rate
