水稻节水高产栽培间歇灌溉技术

Intermittent high-yield cultivation of rice water-saving irrigation technology

通过对稻田不同水分管理模式和间歇灌溉的对比试验研究表明,水稻间歇灌溉水分管理模式最节水、灌水次数及田间排水量最少,且可明显减少病虫危害和增加水稻单产;由此提出了提高降雨利用率、减少稻田渗漏量及适当减少蒸发量的间歇灌溉水分管理模式,可适合我国南方大部分水稻作物种植区推广应用。

The different water management model for paddy fields and intermittent irrigation comparative studies showed that intermittent rice irrigation water management model of the most water,irrigation frequency and displacement field at least,and can significantly reduce pests and diseases and increase rice yield;increasing rainfall utilizatioing,reduce rice fields to reduce leakage and proper evaporation of the intermittent irrigation water management model may be suitable for the majority of rice in southern China crop-growing areas.
