Effects of Different Fertilizer Combinations on Growth and Nutrition of Camellia oleifera
摘要
Abstract
The effects of different fertilizer combinations on the growth and nutrition of Camellia oleifera were studied to select the fertilizer combination that is conducive to the growth of C.oleifera.Ten-year-old common C.oleifera Cenruan 3 was used as the material.Ten experimental treatments with different N∶P∶K ratio and dosage,and different dosage of organic fertilizer were set.The physiological indexes of fruit traits,leaf traits and nutrition of C.oleifera at different growth stages were measured,and the analysis of variance,multiple comparisons and correlation analysis were performed.The results show that 0.5 kg N∶P∶K(20∶8∶17)+5 kg organic fertilizer+0.25 kg medium elements wa-ter-soluble fertilizer(Ca+Mg≥10.0% )had the best growth effect on C.oleifera.This fertilizer combination could ef-fectively increase the fruit size,leaf area,net photosynthetic rate,transpiration rate and contents of nitrogen,phosphorus,potassium,calcium and magnesium in trees,which is conducive to the storage and distribution of tree nutrition.In con-clusion,0.5 kg compound fertilizer N∶P∶K=2∶1∶2 and 5 kg organic fertilizer applied together twice one year in the Spring and Autumn had a better effect on the growth and nutrition of C.oleifera.关键词
