1 Overview Suining County is located in the southern part of Guangxi Zhuang Autonomous Region, Nanning City, is a county, the county is divided into 15 towns, 6 townships, 4 development zones, with a total population of 895,000 people, with a total area of 4725km ~ 2, of which cultivated land For 75300 hm ~ 2, She area 41200 hm ~ 2. The main food crops are rice, followed by corn; sugar cane-based economic crops, followed by peanuts, watermelons, vegetables and so on. In 1996, the county's total grain output was 368,400 tons and raw material cane was 1,338,000 tons, making it one of Guangxi's major grain-producing and sugar-producing bases. The county is a subtropical climate, sunny, abundant rainfall, the average annual rainfall of 144d, the average annual rainfall of 1243.7mm. However, due to the uneven distribution of rainfall in time and space, the evaporation is greater than the rainfall and other reasons, so often spring drought and autumn drought. For more than 40 years since the founding of the People's Republic, there have been varying degrees of drought almost every year. In recent years, the drought is more serious in 1989, when my county less rainfall, only 787mm, but very uneven distribution of time and space, resulting in the county that year 7553hm ~ 2 farmland drought, which must
