Problems solved by technology

2. Soil organic matter is too low
The soil organic matter content is low, the availability of iron decreases, and it cannot be absorbed and utilized by fruit trees
3. Excessive phosphorus, manganese or zinc content in the soil may cause iron deficiency, and unreasonable fertilization, especially excessive application of phosphorus fertilizers, may also easily cause iron deficiency

Embodiment

[0019] (1) Improve the soil and fertilize, dig trenches between the rows of pear trees in autumn, and backfill the soil, weeds, leaves, and straw with a mixture of ammonium bicarbonate and superphosphate with a weight ratio of 1:1, and apply 10 per square meter. grams of mixture;

[0020] (2) Balanced fertilization, the weight ratio of applying nitrogen, phosphorus, potassium fertilizer and organic fertilizer and micro-fertilizer per mu is 1:1:1:2:2;

[0021] (3) Spray iron fertilizer, spray 10% ferrous sulfate aqueous solution once every 10 days, and spray 3 times;

[0022] (4) Increase iron fertilizer, iron fertilizer and organic fertilizer are mixed with weight ratio 1:20, adopt bar to apply, fertilize once every interval 30 days, continuously 2 times;

[0023] (5) Drill holes to apply fertilizer, and use the needle infusion method to input Guangtai micro-fertilizer, once in total;

[0024] (6) Reasonable irrigation should not only ensure the normal water supply of the fr...

Abstract

The invention discloses a prevention method of fruit tree iron deficiency chlorosis. The method is characterized in that the method comprises the following steps of (1) soil improvement fertilization; (2) balanced fertilization; (3) iron fertilizer spraying fertilization; (4) iron fertilizer increasing application; (5) drilling fertilization; (6) reasonable irrigation; (7) orchard ploughing. According to the prevention method of the fruit tree iron deficiency chlorosis, the incidence rate of the fruit tree iron deficiency chlorosis can be lowered.

Description

technical field [0001] The invention relates to the field of plant protection, in particular to a method for preventing and treating iron-deficiency chlorosis of fruit trees. Background technique [0002] Iron-deficiency yellowing disease of fruit trees first manifests from the young leaves at the top of new shoots. In the early stage, the mesophyll loses green and turns yellow, and the veins remain green. The leaves are yellowish-white, and the lower old leaves also appear yellow, and then necrotic spots appear on the top leaves of new shoots, and brown scorched spots begin to appear on the edges of the leaves, and the leaves gradually become necrotic. . In addition to the symptoms of chlorosis on the leaves, the fruits also show yellowing. [0003] The cause of fruit tree yellowing is considered to be caused by iron deficiency, which is caused by the low availability of iron in the soil and poor mobility in plants. The main reasons for iron deficiency are as follows: 1....
