Since the onset of summer in 2006, the climate has become anomalous, the rainfall has decreased, the spatial and temporal distribution has been uneven, the drought has lasted for more than 40 days and the drought and drought weather has lasted for more than 40 days. As a result, large- And even cut the absolute yield. The main factor is the long-term high temperature and drought weather, but there are also human factors in it. Looking at the cracked earth, withered seedlings, the vast number of peasants and friends without tears, and as a water department workers in the mouth department, when sore, more should be deep thinking, when the drought comes, we Why can not they cope easily and easily avoid drought? When the drought comes, why can not large-scale large-scale crops grow vigorously under the hot sun? The most crucial and important factor is “water”. The author of this paper takes such problems as the water conservancy people’s occupational habits and begins with “water” to fundamentally seek measures to eliminate drought and try to solve the drought problem.
