Method for reducing morbidity of adinandra nitida leaf spot

Abstract

The invention discloses a method for reducing morbidity of adinandra nitida leaf spot. The method comprises the steps of from the second year after adinandra nitida is planted, applying a peanut branand a farmyard manure on the adinandra nitida after raining during November to December of each year, wherein the weight ratio of the peanut bran to the farmyard manure is (2 to 4) : (6 to 8), the application amount of the fertilizer is 100 to 150g applied to each two-year-old adinandra nitida, and for the adinandra nitida with a tree age larger than two years, the application amount is increasedby 10 to 20 percent on the basis of the application amount of the last year when one-year-old tree age is increased every time. By statistics, the fertilizer is applied according to the method provided by the invention, so that without changing other daily management manners, the morbidity of the adinandra nitida leaf spot in a tea garden is reduced by 12 to 45 percent compared with the morbidityof the adinandra nitida leaf spot in an existing conventional management tea garden.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for reducing the incidence of Shiya tea spot disease. Background technique [0002] Shiya tea, also known as Shiyan tea and Shishan tea, is scientifically known as Bright Ye Huang Ruimu, Yangtong genus, arbor. It got its name because it grows on the cliff. Its buds and leaves are plump, and the tea soup it makes is bright in color. Its main components are: 20% flavonoids, 23.4% tea polyphenols, 9.73% amino acids and wild alkaloids and other elements beneficial to the human body. It is currently found in natural plants with the highest flavonoid content. It is a treasure among teas of rare original ecology and pure natural green plants in China. [0003] Shiya tea mainly grows on the cliffs of high-altitude virgin forests. In ancient times, monkeys were trained to pick it, and it is also called "monkey picking tea" among the people. Because wild Shiya tea is ...

But no matter which of the above methods is used, the Shiya tea is sprayed with chemical agents, which will not only affect the environment and the quality of Shiya tea, but also because they all start to prevent and treat the leaf spot disease after the occurrence of the disease. , plus the control effect of any disease can not reach 100%, therefore, the above method is difficult to fundamentally reduce the incidence of Shiya tea spot disease
