不同灌溉方式对水稻生长及产量的影响
Effects of Different Irrigation Methods on Paddy Rice Growth and Yields
摘要
Abstract
The rice growth and yields under four different irrigation methods were studied. The results showed that different irrigation method had significantly different impact on the rice growth, physiological characteristics, the dry matter accumulation and the production. The shallow irrigation was the optional method for rice growth and yields compared with other irrigation methods, and the dry irrigation method was the worst. Compared with the dry irrigation method, plant height, the tiller number and photosynthetic rate under the shallow irrigation method all rose, and the seed setting added by 41.5%, 1000-grain weight increased by 1.6 g, and the output increased by 15.8 g/pot significantly. Compared with the deep water irrigation method, the yield and the irrigation efficiency of the shallow irrigation increased by 7.6 g/pot and 0.69 kg/m\ respectively. The yield of the intermittent irrigation was equal to that under the deep flooding irrigation, but the irrigation efficiency was 0.44 kg/m3 higher than that of the deep flooding irrigation. Therefore, according to the characteristics of the seasonal drought, the shallow irrigation method was conducive to the high yield of the late rice and the intermittent irrigation was helpful for the late rice culture in the south of Hunan province.关键词
