Sorghum has strong cold resistance, not only can resist soil drought, but also can resist atmospheric drought. At the same time, sorghum is tolerant to waterlogging, and its waterlogging resistance is especially obvious after booting. Sorghum seedling growth is slow, require less water, accounting for about 10% of the water requirement of growth period; from jointing to booting water demand maximum, accounting for 50%, during this period, such as water shortage will affect plant growth and spike differentiation; booting to flowering stage water demand accounted for about 15%, water shortage will cause card neck drought, is the critical period of water requirement of sorghum; filling period accounted for 20%, such as drought will effect of dry matter accumulation, lower grain weight; mature period of water demand was significantly reduced, only about 55%. Precipitation during the whole growth period was 400~500 Mm, evenly distributed, can meet the needs of sorghum growth. 2. how about the water requirement of millet? Water requirement is the amount of water needed for crop life and the amount of water allocated at all times. From the water requirement of the early, middle and late stages of plant growth, it is a process of change from less to more or less. Coarse grain from seedling to jointing stage or branching stage is the stage of vegetative growth, plant size, slower growth, less water consumption; jointing or branching to flowering stage is the vegetative growth and reproductive growth stage at the same
