We are here to sow millet sowing the first 5 days to 2 days after the best, but then the kinds of millet and easy to burn buds, through three years of observation and testing, the first time to find out the causes and prevention of burning buds. The reason for the occurrence of burning buds: due to drought, to explore soil moisture sowing, sowing 2.5-inch, after sowing with sow, after the sudden emergence of rain (10-20 mm), the surface 5-8 mm thick layer of knot formed, the air Drying, the temperature is higher than 35 ℃, the soil layer junction layer temperature is higher than 41 ℃, the contact area
