养分平衡调节技术是将计算机技术应用于农业生产中，把作物———土壤———肥料作为一个系统，综合分析三者之间的养分平衡关系，并将它们定性、定量化。把作物体内各营养元素间的比例平衡做为重点，在水稻生育的各个时期，及时地、快速地进行植株诊断，并全面地、按比例地为水稻提供生长所需的各种营养元素，来满足高产优质的需要。此技术可增加水稻有效分蘖，增强抗病、抗倒伏能力，克服妨碍水稻正常生长因子的影响和盲目施肥现象，减轻环境污染，空瘪率下降，千粒重增加，而且又提高了品质。应用四年，平均增产１１．６％～２６．７％，每公顷平均增产稻谷１２７５．６ｋｇ，增值３０１２．７元，投入产出比１∶１６．２。是一项集科学、生产效益为一体的完整的施肥技术体系。 Nutrient balance adjustment technology is the computer technology used in agricultural production, the crop --- soil - fertilizer as a system, a comprehensive analysis of the relationship between nutrient balance between the three, and their qualitative and quantitative. The crop nutrient balance between the various elements as a key point in all stages of rice growth, timely and rapid plant diagnosis, and comprehensively and proportionally to provide rice growth for a variety of nutrients to Meet the needs of high yield and quality. The technology can increase effective tillering of rice, enhance resistance to diseases and lodging resistance, overcome the effects of preventing normal growth factors and blindly fertilizing rice, reduce environmental pollution, reduce emptying rate, increase 1000-grain weight, and improve quality. Application of four years, an average increase of 11.6% ~ 26.7%, an average yield of 1275.6kg per hectare of rice, added value 3012.7 yuan, input-output ratio 1:16.2. Is a collection of science, production efficiency as one of the complete fertilization technology system.
