Researches On Leaf Nutrient Analysis Of Olive And The Effects Of Different Formula Fertilization On The Growth And Yield

Nutrition diagnosis of fruit trees by the leaf analysis, soil analysis or determination of visible symptoms, physiological and biochemical indicators to determine the nutritional status of fruit trees. Today still leaves the nutrient diagnostic technology analysis as the basic means and methods supplemented by soil analysis. According to the results of leaf and soil analysis, control has been established diagnostic criteria, identified the various elements of the profit and loss situation, and thus the development of rational fertilization program. Leaves analysis the nutrient index method is more commonly used in nutritional diagnostic methods. Through the method of Leaf Element Analysis to Ratio, The fertilizer formulation traditional fertilization for comparison of olive, Formula fertilization effects compared with conventional fertilization, Has the following advantages:(1) The group of Leaf Element Analysis to Ratio can increase the proportion of full flower of Olive.(2) Speed up the rough growth of Olive fruit.(3) Reduce the ratio of chlorophyll a/b.(4) Reduce68%of the Disease Index of occurring diseases and insect pests frequently in Olive.(5) Drop rate of Olive fruit is reduced by1～25%.(6) Promote the ratio of fresh and pyrenes slightly.(7) Increase fruit yield85%; Increase Olive-oil yield93%. After the formula-fertilization, the highest direct benefit can touch to81450yuan, the rate of direct benefit enhanced47%tol51%, the highest deep processing benefit can touch to213690yuan, the rate of indirect benefit enhanced53%to156%.
