Control method for nutrition deficiency yellows of cherries

Abstract

The invention discloses a control method for the nutrition deficiency yellows of cherries, and belongs to the technical field of fruit and vegetable cultivation. The control method for the cherry nutrition deficiency yellows achieves the purposes that operation is easy, cost is low, and the cure rate is high. According to the technical scheme, balanced fertilization of cherries is enhanced, different types of fertilizer is applied to cherry trees in the time period from the first ten days of September to the end of September, the time period before sprouting in the spring of the next year, the time period after blossom drop in spring and the time period after harvesting of cherries, the fertilizer utilization efficiency of cherries is maximum, the yellows caused by nutrition deficiency is eradicated, and the method can also be used for treating the nutrition deficiency yellows of cherries.

Description

technical field [0001] The invention discloses a method for preventing and treating cherry deficiency yellowing disease, which belongs to the technical field of fruit and vegetable cultivation. Background technique [0002] Cherry is the earliest fruit tree species of deciduous fruit trees in northern China after Chinese cherry. According to traditional Chinese medicine, cherries have the functions of regulating Qi and expelling rheumatism. [0003] The main symptom of cherry deficiency yellowing disease is yellowing of leaves or reticulated yellowing of leaves. In the early stage, the mesophyll loses chlorosis and turns yellow, and then the degree of yellowing increases. Yellowing occurs, brown scorched spots begin to appear on the edges of the leaves, and the leaves gradually become necrotic. In severe cases, the leaves scorched and fell off, and the terminal buds died, resulting in the death of the whole fruit tree. [0004] The cause of cherry yellowing is due to the l...

Problems solved by technology

[0004] The cause of cherry yellowing is due to the lack of iron, magnesium, zinc, manganese and other elements in the cherry tree. The reason is that these elements have low availability in the soil and low mobility in the body of the cherry tree.

The main reasons for the lack of nutrients in cherry trees are as follows: the soil contains a lot of salt and alkali, and in alkaline soil, the pH is too high, so that iron, magnesium, zinc, manganese and other elements are converted into inactive elements, which cannot be directly absorbed and utilized by plants , forming deficiency chlorosis; the soil organic matter is too low, the organic matter content in the soil is low, the availability of elements decreases, and they cannot be absorbed and utilized by the root system; the content of phosphorus, manganese, and zinc elements in the soil is too high, and unreasonable fertilization causes The antagonism of certain elements; soil quality and irrigation, orchards with heavy soil and poor drainage generally have a severe incidence of deficiency disease, and more irrigation will easily cause the root system to be in a state of hypoxia, affecting the absorption of various elements by the root system, resulting in Deficiency Chlorosis Symptoms
