1.稻穗在5～100％的CO_2气体中放置0.5～6分钟,5～10分钟后开颖,且花粉活力不受影响。田间应用时可把CO_2气体先充入保温瓶中,将穗在瓶中放1～2分钟后取出即可;2.pH≤5.6的CO_2溶液浸穗能显著地加快开颖。应用时可把CO_2饱和溶液装入量筒或水瓶中,穗在溶液中浸1～2分钟后取出放在空气中。3.0.2M左右的碳酸盐(如Na_2CO_3)加稀酸(如HCl)的反应液(pH<7)浸穗对开颖也有
1. Rice ear is placed in 5 ~ 100% CO 2 gas for 0.5 ~ 6 minutes, 5 ~ 10 minutes after opening, and the pollen vitality is not affected. CO_2 gas can be filled into the thermos flask first when the field is applied, and then the spikes are taken out in the bottle for 1 to 2 minutes; 2. The immersion of the CO 2 solution with pH ≦ 5.6 can significantly speed up the opening. Applications CO 2 saturated solution can be loaded into a measuring cylinder or water bottle, spike immersed in solution 1 to 2 minutes after taking out in the air. About 3.0.2M carbonate (such as Na_2CO_3) plus dilute acid (such as HCl) reaction solution (pH <7)
