PYB1.6型多功能移动式节水补灌机春小麦补灌指标研究

Index of irrigation spring wheat with the water-saving supplement irrigation machinery

1997年至2000年,研究了PYB1.6型多功能移动式节水补灌机在半干旱偏旱区海原县兴仁镇春小麦的补充灌溉指标.结果表明,在春小麦平作、垄沟栽培、穴播栽培、膜侧栽培等栽培方式下,利用该补灌机在小麦三叶期、拔节期、抽穗期、开花期补充灌溉,当预期产量为1050kg hm2时,其补充灌溉指标依次为58mm,42mm,38mm和35mm,节水率(以平作补灌为对照)依次为0,27.6%,34.5%和39.6%.

Index of irrigation spring wheat with the watersaving supplement irrigation machinery was studied at experiment base of Haiyuan county of arid and half arid area in 1997-2000.The results showed that index of supplement irrigation spring wheat of the flat,the ridge and furrow,the film hole sowing,the film ridge and furrow on emergence stage,elongation stage,heading stage,flowering stage were 58?mm,42?mm,38?mm,35?mm,respectively.Watersaving rate (flat CK) was 0,27.6%,34.5%,39.6%,respectively.
