Problems solved by technology

[0003] Pear tree is a perennial crop, which grows in a fixed position for a long time, and the scope of the root system to absorb nutrients is limited. Therefore, it is easy to cause the lack of certain nutrients in the soil around the root system. Deterioration, soil compaction, poor soil ventilation and water permeability, lead to yellowing of pear orchards, and the area of ​​yellowing has a tendency to expand, seriously affecting the yield and quality of pears, and hindering the pear industry. Sustainable and healthy development
In the prior art, the prevention and treatment of fruit tree yellowing is mainly to spray compound fertilizers and chemical agents, etc., but it cannot fundamentally prevent and treat pathological pear tree yellowing. Therefore, it is necessary to develop a pear tree with good control effect and more comprehensive protection. Tree yellowing disease control methods

Embodiment 1

[0051] A kind of control method of pear tree yellowing disease:

[0052] (1) Apply vegetable protein organic fertilizer and bio-organic fertilizer before the germination of pear trees: about 20 days before the germination of pear trees, dig a 35cm wide and 25cm deep annular ditch at a distance of 1m from the trunk under the crown, and apply 0.5kg per plant plant protein organic fertilizer and 2kg of bio-organic fertilizer, and then mix it with the soil and backfill.

[0053] Preparation of plant protein organic fertilizer: Mix 50 parts of flower seed meal, 20 parts of carnation branches, 30 parts of bran, 20 parts of loofah seeds, 1 part of Aspergillus niger extract, 2 parts of Bacillus subtilis, 1 part of lactic acid bacteria and 30 parts of water After uniformity, airtight fermentation is carried out for 72 hours at a temperature of 30° C., then dried at 40° C. and pulverized to obtain a vegetable protein organic fertilizer.

[0054] Preparation of bio-organic fertilizer: M...

Abstract

The invention discloses a method for controlling yellows of pear trees, and belongs to the technical field of agriculture. The method for controlling yellows of the pear trees comprises the following steps: applying a vegetable protein organic fertilizer and a biological organic fertilizer before pear trees germinate; applying compound fertilizer in the early germination stage of the pear trees; spraying an attractant in the early germination stage and the flowering stage of the pear trees; spraying a mixed leaf fertilizer in the leaf expansion period of the pear trees, and carrying out conventional field management. According to the method for controlling yellows of the pear trees, yellows of the pear trees are effectively controlled, the occurrence rate of the yellows of the pear trees is greatly reduced, the recurrence probability in the next year is remarkably reduced, and an effective guarantee is provided for healthy development of the pear tree industry.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for preventing and treating yellowing disease of pear trees. Background technique [0002] Yellowing disease is a symptom of plants, which refers to the phenomenon of yellowing or yellowing of some or all of the stems and leaves. Yellowing diseases are divided into physiological yellowing diseases and pathological yellowing diseases. Physiological yellowing diseases have many causes, and the most common one is iron deficiency yellowing, which mostly occurs in the cultivation of acid-loving flowers such as rhododendrons and gardenia in northern areas. When planting seeds, hydrangea, jasmine, etc., the new leaves will turn yellow, and in severe cases, the leaves will turn brown and dry. In addition, sulfur deficiency, nitrogen deficiency, excessive light, excessive watering, low temperature, and drought can also cause yellowing of leaves. The disease is mainly solve...
