生姜催芽过去多用火炕催芽法。一般需30～40天的时间,掌握不好,常常造成种姜霉烂。今年,我们在第一生产队分别用沙床和立壕沟进行催芽试验,结果,沙床催芽效果好。此法不用热炕,不用加温,简单易行,可大面积进行。具体做法是: 4月17日把种姜放在立壕内的防寒沟里,上面盖草苫保温。据测定:早晨8点钟平均温度为17℃,下午1点钟平均温度为21.2℃。由于温度较低,满足不了种姜发芽的需要,于4 Ginger germination in the past with the kang germination method. Generally take 30 to 40 days, badly grasp, often caused by ginger rot. This year, we conducted the germination test on the first production team with sand beds and trenches. As a result, the sand bed was very effective in promoting germination. This method does not have thermal kang, do not heat, easy, can be large area. The specific approach is: April 17 kinds of ginger placed in the vertical trench within the cold trench, covered with grass 苫 insulation. It is measured: 8 o’clock in the morning the average temperature of 17 ℃, 1 o’clock in the afternoon the average temperature of 21.2 ℃. Due to the lower temperature, can not meet the needs of seed germination, in 4
