对于早秋蔬菜,播种时由于气温高,发芽率低,因而需低温处理,打破休眠,促其发芽。莴笋种催芽先将种子放入冷水中浸30分钟捞出后待稍干,再放入离水面1米左右的深井中催芽,一般3-4天可发芽;也可将种子浸湿后放入冰箱冷藏室冷藏,每隔4小时拿出,置于常温下4-6小时,连续2-3天,然后将种子置于阴凉处1-2天可发芽。当有70%以上种子发芽后即可播种。菠菜种催芽将种子浸凉水约12小时后,放在4℃低温的冰箱里24小时,然后在20℃-25℃的条件下催芽,经3-5天出芽后播
For early autumn vegetables, sowing due to high temperatures, low germination rate, which requires low-temperature treatment, breaking dormancy and promote its germination. Lettuce seed germination First seed into the cold water soak for 30 minutes after the fish out to be slightly dry, and then into the deep well about 1 meter from the surface in the germination, usually 3-4 days can germinate; Refrigerator freezer refrigerated, taken out every 4 hours, placed in room temperature 4-6 hours, for 2-3 days, then the seeds in the shade 1-2 days can germinate. Seeds can be planted when more than 70% of the seeds germinate. Spinach seed germination The seeds soaked in cold water for about 12 hours, placed in a refrigerator at 4 ℃ low temperature for 24 hours, and then germination under conditions of 20 ℃ -25 ℃, germination after 3-5 days of broadcast
