【摘要】 针对目前甜菜种植过程中普遍灌水和施肥量过大造成的浪费资源、污染环境等问题,以比对照田(CK)含糖率增加0.5度、节水10%以上、肥料用量减少20%以上为总体目标,开展了节本稳产增糖栽培技术集成模式示范。通过一年的对比示范结果表明:示范田较对照田(CK)节水18.69%、化肥用量减少51.2%,甜农节本2 065.23元/hm2;块根产量增加9.29%、含糖率提高2.94度,增收4 155元/hm2,两项合计增加收入6 220.23元/hm2。实际效果验证了甜菜节本稳产增糖栽培技术集成模式的可行性,为发展现代生态农业提供技术支撑。更多还原

【Abstract】 In view of the problems such as waste of resources and pollution of environment caused by excessive irrigation and fertilization in the current sugarbeet planting, the demonstration experiment of integrated cultivation technology for saving cost, stable yield and increasing sugar production was carried out, and its overall goal is to increase sugar content by 0.5%, save water more than 10%, and reduce fertilizer use by more than 20% compared with the control. The results of a year’s comparative experiment showed that the demonstration field of sugarbeet can save water 18.69%, reduce the amount of chemical fertilizer by 51.2% compared with the control, and cost of sugarbeet farmer can save 2 065.23 yuan/ha; the root yield of sugarbeet increase by 9.29%, sugar content increase by 2.94% compared with the control, and income increase by 4 155 yuan/ha. The two items add up to 6220.23 yuan/ha. The practical results verified the feasibility of the integrated model of sugarbeet cultivation technology, which provided technical support for the development of modern ecological agriculture.更多还原
