摘要

In this paper it had been analyzed on some nutritional characteristics of super hybrid rice, such as more requirement of fertilizers,stronger absorption capacity of nutrition for individuals,higher efficiency of nutritional utilization,and extra much nutrition requirement at later growth stage.Some specific methods saving nitrogen fertilizer and controlling pollution had been put forward, including establishing fertilizing principle in specific region, precisely fertilizing in specific field,applying special fertilizer for super rice.scientific application of fertilizers.lt had also discussed on some cultivation measure to reach high yields with saving nitrogen fertilizer and controlling pollution, for example, raising stronger seedling to decrease amount of fertilizers in field,scientific management for water and fostering population with high photosynthetic efficiency for increasing fertilizer efficiency to achieve goals both high yield and nitrogen pollution control. This technology had broadly been applied on cultivation of super rice in Wenzhou,with saving pure nitrogen 39.0 kg per ha and increaseing an average yield of 63% than conventional cultivationshich reduced the fertilizer pollution to the environment on a large scale and remarkably increase the output and the benefit of planting super rice.
