不同灌溉技术条件对冬小麦生产的影响
Effect of different irrigation technology on production of winter wheat
摘要
Abstract
The object was to explore the effect of different irrigation technology ( drip, sprinkler and flood irrigation) on the yield components of winter wheat. Different irrigation technology was is applied in the field to research effect of different irrigation technology on the yield components. Such results as follow:the rate of decline soil moisture on the surface is the smallest and the soil moisture is highest when the drip irrigation is applied. The height of winter wheat of drip irrigation applied is 12％ and 5％ more than that of sprinkler and flood irrigation, respectively. The yield of the drip and sprinkler irrigation applied is 8.63％ and 7.75％ more than that of flood irrigation. The weight of one thousand of grains under drip,sprinkler and flood irrigation was 43.36, 42. 17 and 41.17 g respectively.The grain weight is also more than that of flood irrigation and likewise the biomass, which is 6.9％ and 3％ higher under drip and sprinkler irrigation. This implies that the drip irrigation is better to used when the overall objective is to increase the water use efficiency. And likewise sprinkler irrigation is also better than flood irrigation.关键词
