由于受传统习惯的影响,人们多认为水稻灌水越多越好,深水淹灌的灌溉方式,用水量大且不附合水稻生长需求的惯例,产量也难以提高。为改变深水淹灌的落后方式,广西各灌溉实验站进行了21年的实验,研究出了水稻薄、浅、湿、晒的优良灌溉制度,使水稻获得既节水又增产的双重效益。 该项目实施两年,累计推广面积达2672万亩,总增产稻谷3.36亿公斤,平均每亩增产25.14公 Due to the influence of traditional habit, people think more and better rice irrigation, deep-water irrigation irrigation methods, water consumption and does not meet the needs of rice growth practice, production is also difficult to increase. In order to change the backward ways of deep-water flooding irrigation, Guangxi Irrigation Experimental Station has conducted 21 years of experiments and developed excellent irrigation systems for thin, light, wet and sun rice so as to obtain the double benefit of both water-saving and yield-increasing rice. The implementation of the project for two years, a total area of ​​2672 acres of promotion, with a total increase of 336 million kilograms of rice, an average yield of 25.14 acres per mu
