Advances in Research on the Correlation between the Mineral Nutrition and Tree Growth

Maximum benefit can be obtained by the most rational and scientific methods resulting from research on the correiation between nutrition and tree growth.The main contents of research are:nutritional diagnosis,fertilizer application, choice of tree species adapted to particular soils,early prediction of tree growth and tree variety improvement.The research methods include field experiments hydroponics and isotopic tracer experiment.Since 1935,the research on the correlation between nutrition and tree growth has been focused on basic theory,stead-state theory and NUE theory.In view of the genetic research on mineral nutrition and the trend for its application, researches on the physiological process of mineral nutrition in various genotypes and the relevant genetical problems,and researches on the various influences produced by mineral nutrition and genotype growth should be strengthened.
