Abstract

The invention relates to a method for diagnosing and correcting leaf chlorosis of a plant, in particular to a method for diagnosing and correcting leaf chlorosis of a brilliant variety of a blueberry.The method for diagnosing and correcting the leaf chlorosis of the brilliant variety of the blueberry comprises the following steps: A, observing the external symptom of a plant leaf; B, measuring the SPAD value of the plant leaf; C, measuring the pH value of the rhizosphere soil of the plant; D, measuring the internal nutrients of the plant leaf and the ratio; E, diagnosing; F, implementing themethod for correcting the leaf chlorosis. The method uses the four steps of observing the external symptom of the plant leaf, measuring the SPAD value of the plant leaf, measuring the pH value of therhizosphere soil of the plant, and measuring the internal nutrients of the plant leaf and the ratio to accurately diagnose whether the plant of the brilliant variety of the blueberry suffers from theleaf chlorosis and diagnose the degree of the disease, so that the method has better effects on regulating the pH value of the rhizosphere soil of the plant of the brilliant variety of the blueberry suffering from the leaf chlorosis and preventing the plant of the brilliant variety of the blueberry from getting to the heavy chlorosis from the light chlorosis.
