Symptoms and control measures of boron deficiency in peach trees

Peach tree

The symptoms of boron deficiency in peach trees are as follows: the top of the branch is easy to die; under the dead part of the peach tree, a lot of messy new branches will be sent into a "broom"; the phloem of the branch becomes brown, the branch is easy to flow gum, the leaf is narrow and wrinkled, the petiole and vein are bent, and the quality is brittle and easy to break; the leaf color is yellowish, the fruit is deformed, and the color is different. The light boron deficiency leads to the weakness of peach trees, low yield and poor quality. most of the branches of peach trees with heavy boron deficiency die or have buds but no flowers, resulting in no yield.

Prevention and control measures:

1. The application of organic fertilizer and irrigation after application can promote the transformation of available boron in soil and increase the content of soluble boron in soil.

2. Combined with base fertilizer, each peach tree was treated with borax or boric acid 50ml 150g. After irrigation, the period of validity of boron supplement can be up to 3mi for 5 years.

3. Boron is sprayed on the leaf. Spray 0.5% borax solution on peach canopy 3 times before sprouting, blooming, blooming or after flowering, depending on the situation.
