保墒保苗,扎好种子根:种子根的作用在于保苗。谷子出苗后只要种子根不断,一般是旱不死的。要使种子根发育好,播种时必须让种子接上湿土。必要时进行抢墒播种、借墒播种或增墒播种,播后压地提墒。据试验,在春旱情况下,播种后压地1次出苗率为60％,压地两次为70～80％,压地3次可达90％。 Preservation seedling, tie the seed root: the role of seed roots is to protect seedlings. As long as the emergence of millet seedling roots continue, the general is immortal drought. To make the seed root well developed, sow the seeds must be connected to wet soil. If necessary, grab moisture sowing, sowing moisture or seeding by planting moisture, sowing pressure after sowing. According to the test, in the case of spring drought, the emergence rate of seedlings after inoculation was 60%, twice in 70-80% and in three times in up to 90%.
