Zhengzhou Area Dry Saving Water Agricultural Present Situation Analysis And Development Countermeasure

Zhengzhou is located in the mountains to the west of Henan Province and residents in Huanghuai Plain transition zone. It is topographically high in the west and low in the east. The mountains, hills and plains take up about one-third each. The annual average precipitation is about 650mm and various much in different areas and time. The rain drop unevenly distributed seasonally and drought happened very often. Zhengzhou is belonged to sub-humid areas prone and there is no irrigation conditions at hill area and low mountains in western. Agriculture depends entirely on natural precipitation. According to the statistics, nearly 50% of agricultural area is lack of irrigation. Agriculture's ability to resist natural disasters is very weak, especially in the western hilly area (including Xinzheng, Ying-yang, the majority of Xinmi, Gongyi north-east, central and eastern parts of Dengfeng). Although the soil has a deep surface layer, most soil is sandy loam because of the nature of Yellow Soli which has a poor water-retention capacity. So, the development of water-saving agriculture is a must and only way for the development of future agriculture in Zhengzhou.The local agricultural professionals and technicians in Zhengzhou are facing practical problems for the water-saving agriculture at present. But they conducted a comprehensive research and development work to solve the issues. Till the late 90's, a water-saving agriculture cultivation technology for dry area has been initially formed with anti-seepage, balanced fertilization, mulching, straw and other elements.However, the problems of Water-saving agriculture development emerged out gradually when China's economy continues to develop. The water resource control is lack of macro-control. The public do not pay enough attention on water conservation. The agricultural activities are short of government subsidies. The will of water-saving is unified between government and farmers. The recycled usages of water resources in agriculture do not receive enough attention. The water-saving technology is out-of-date and low level of overall integrated applications on water-saving technologies. It is difficult to play the whole water-saving efficiency.Though the development of water-saving agriculture in Henan province and other experience domestic and foreign water-saving agriculture systems, Zhengzhou has come out several solutions for the problems faced by its actuarial agricultural development:Government supports more in water-saving agriculture structure, including publicity and training. An incentive mechanism will be set up. Formulate the macro-planning and guides on water-saving agriculture. Focus on the structural development of region's water-saving agriculture. Improve on the technology of safety of low-quality irrigation water for farm. Make full use of local water resources. Improve the water-saving technologies; Improve water-saving techniques for early season integration. Speed up the development of integrated water-saving agriculture technology and models.
