北京市小果型西瓜和甜瓜灌溉现状调研OA北大核心CSTPCD

This study investigated and surveyed the irrigation conditions of 116 small fruit type watermelon and melon growers in 7 districts of Beijing;and analyzed the irrigation water source,irrigation method and irrigation system.The results showed that only 43.5％of the planting parks had both frequency conversion and filtration equipment at the head of the irrigation shaft.Individual farmer households only accounted for 15.9％.And 57.0％of the respondents adopted water-saving irrigation method,47.7％of them adopted drip irrigation,and 9.3％of them used micro jet.The irrigation volume for small fruit type watermelon in spring was mainly 1 500～2 250 m3·hm-2(taking 35.4％).The irrigation volume for small fruit type watermelon in autumn was less than 1 500 m3·hm-2(taking 46.3％).While,the irrigation volume for spring melon was mainly less than 1 500 m3·hm-2(taking 52.6％).In response to the existing problems,the paper puts forward suggestions for future development.They were perfecting integration system,optimizing water-saving irrigation mode,and increasing promotion effort,etc.
