一、试验目的在盐碱地上井水种稻,洗碱和节水存在着矛盾。历来为了使秧苗不受碱害,一直采取淹灌洗碱压碱的常规措施,但用水量大,成本较高,地温也低,并由此导致了秧苗生育缓慢,影响产量。开鲁县经过几年实践表明,实行节约用水,合理灌溉,可降低成本,提高地下水资源利用率,增加单位面积效益,达到增产低耗的目的,带来明显的经
First, the purpose of the experiment Salinity in the well water rice, washing alkali and water there is a contradiction. Traditionally, in order to prevent the seedlings from alkali damage, conventional measures of flooding caustic soda have been taken, but the water consumption is large, the cost is high, and the ground temperature is also low, which leads to the slow growth of the seedlings and affects the yield. After several years of practice in Cairo, it has been shown that the implementation of water conservation and rational irrigation can reduce the cost, improve the utilization rate of groundwater resources, increase the unit area benefit and achieve the purpose of increasing production and reducing consumption,
