Second, the drought sowing I flag drought planting summed up in a “top”, “grab”, “lead”, “anti” four ways. “Top” is the top seed sowing, that is, in the early spring soil Kaihua back to the time (Qingming to Guyu), early sowing early, which can effectively use the soil Kaihua back to the water, to meet the needs of seed germination, so as to seize Sanae, all seedlings. My flag uses this measure to sow crops such as wheat, sunflower, marijuana, millet and so on. As long as the seeds are selected well, the germination rate is high and the apron is sown properly, and the whole plant can generally be seized. “Grab” is to grab time, grab moisture sowing. Make full use of late April to early May this period of soil moisture back to the soil, concentrate on labor,
