Embodiment 1

[0077] From August 2016 to September 2017, in the main blueberry producing area in Yuxi City, two fields with mild yellowing disease were selected to conduct the same-field comparison test. The area of ​​the test field was about 1 mu, and the test period was from flowering to full fruit Expect. After the test plots are selected, half of them will be the conventional fertilization method of the grower (control), and the other half will be the corrective control method (correction). Before implementation, collect upper leaves and lower leaves to detect relevant nutrient elements and chlorophyll SPAD values; after the test, evaluate the change of leaf yellowing, collect upper leaves and lower leaves by treatment and control to detect relevant nutrient elements and chlorophyll SPAD values, and measure Fruit weight.

Embodiment 2

[0104] From August 2016 to September 2017, two fields with moderate yellowing disease were selected in some blueberry producing areas in Kunming City to conduct the same-field comparison test. The area of ​​the test field is about 1 mu, and the test period is from flowering period to full fruit period. After the test plots are selected, half of them will be the conventional fertilization method of the grower (control), and the other half will be the corrective control method (correction). Before implementation, collect upper leaves and lower leaves to detect relevant nutrient elements and chlorophyll SPAD values; after the test, evaluate the change of leaf yellowing, collect upper leaves and lower leaves by treatment and control to detect relevant nutrient elements and chlorophyll SPAD values, and measure Fruit weight.

Embodiment 3

[0131] From August 2016 to September 2017, two fields with severe yellowing disease were selected to conduct the same-field comparison test in some blueberry production areas in Qujing City. The area of ​​the test field is about 1 mu, and the test period is from flowering period to full fruit period. After the test plots are selected, half of them will be the conventional fertilization method of the grower (control), and the other half will be the corrective control method (correction). Before implementation, collect upper leaves and lower leaves to detect relevant nutrient elements and chlorophyll SPAD values; after the test, evaluate the change of leaf yellowing, collect upper leaves and lower leaves by treatment and control to detect relevant nutrient elements and chlorophyll SPAD values, and measure Fruit weight.

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.

Description

technical field [0001] The invention relates to a method for diagnosing and correcting yellowing of plant leaves, in particular to a method for diagnosing and correcting yellowing of leaves of a blueberry variety. Background technique [0002] Blueberry (Blueberry), means the meaning of blue berry. One is a low shrub, wild with short feet, small particles, but high anthocyanin content; the second is artificially cultivated blueberries, which can grow to 240cm high, with larger fruits, more water, and relatively high anthocyanin content Low. Blueberry fruit is rich in nutrients. It not only has good nutritional and health effects, but also has the functions of preventing brain aging, strengthening the heart, anti-cancer, softening blood vessels, and enhancing human immunity. [0003] Brilliant (Brilliant) was bred by crossbreeding in Georgia, USA. It is an early-maturing variety. The plant is strong and erect, with a small crown, easy to grow bases and branches, and blooms ...
