【摘要】 １９９７～１９９８ 年，在山西临汾、洪洞两地就地膜小麦集水有限补灌技术进行了研究。结果表明，不同时期、不同补灌量处理间产量存在显著差异。从补灌时期看，以拔节期补灌产量最高，其次为扬花期，再次为冬前。从补灌量看，在同一补灌时期，补灌量高者产量高，每公顷每次应不低于１５０ｍ３ 。更多还原

【Abstract】 The techniques of catchmental limited irrigation in film mulched wheat were studied in Linfen and Hongtong, Shanxi in 1997～1998, The results showed that wheat yield was significantly different when irrigated in varying periods or with different quantities. Judged by irrigation period, the sequence of wheat yield was jointing stage>flowering>before winter. Judged by irrigation quantity, the higher the irrigation quantity in the same period, the higher the yield of wheat. The quantity is better higher than 150m 3/hm 2 for each irrigation.更多还原
