为研究水稻半耕及节水灌溉的节水、增产潜力 ,1 998～ 2 0 0 0年进行了试验研究 ,并从 1 999年起开展了示范性推广试验。结果表明 ,水稻实行半耕作方式结合节水灌溉 ,与传统的全耕淹灌方法比较 ,具有明显的节水、节支、增产、提高经济效益的效果 ,是一种优良的稻田节水灌溉模式 ,值得总结推广
In order to study the water-saving and yield-increasing potential of semi-tillage and water-saving irrigation in rice, the experimental study was carried out from 1998 to 2000, and a demonstration experiment was carried out from1999. The results showed that the combination of semi-tillage and water-saving irrigation with rice, compared with the traditional all-tillage irrigation method, has the effect of saving water, saving expenditure, increasing production and improving economic efficiency, and is an excellent water-saving irrigation mode , It is worth summarizing promotion
