Mango shoot control method

Before the flower bud differentiation of mango, selecting a suitable climate to control its shoot yield can make the mango branch adjust or delay its growth in time, promote the plant to accumulate more nutrients, promote the fullness of flower bud, and be beneficial to flower bud differentiation. Fruit development and so on. So how to control the mango tip? Come and have a look with the editor.

I. physical tip control method

1. Water control method

When the mango is mature in the last autumn, keeping the soil moderately dry can obviously improve the flower formation. This method is suitable for young and middle-aged trees, but not for old and weak trees.

2. Root-cutting method

Dig a 30-50 cm deep trench outside the mango crown, cut off the absorbing roots of the fruit tree, sun it for 1-2 weeks, and then fill it with organic fertilizer or topsoil. This method is also used for young and middle-aged trees, not suitable for old and weak trees.

3. Ring cutting

This method is through the downward movement of photosynthates from open fruit trees to make the branches accumulate salt slightly and promote flower bud differentiation, generally when the mother branch of the last autumn shoot of the mango tree is close to maturity, and in the trunk of the mango tree or the backbone branch with a diameter of more than 5 cm, make a circular cut, reaching to the xylem.

4. The method of encircling the wire

This method is suitable to be carried out before and after Lesser Cold, winding the mango trunk 40-60 cm above the ground with iron wire for a week, fastening it deep into the phloem until the mango blossoms and then untied.

2. Chemical tip control method

Mango shoot control method mainly inhibits the synthesis of endogenous hormones gibberellin and auxin in plants, increases the content of endogenous hormones in fruit trees, destroys apical dominance, and makes more assimilates distributed to root leaves, lateral buds and floral organs.

1. Foliar tip control method

In general, when the leaves turn green and not fully mature from July to August, it is extremely easy to use 800-100 times, once every 7-15 days, spraying 3-7 times continuously, the number of times is determined by the weather and tree potential.

2. Soil-buried paclobutrazol method

When the second canopy tip of the mango tree grows to 3-5 cm, prepare a certain concentration of multiple frustration, apply it according to the tree condition, open a pair of trenches or ring ditches within the dripping line or 40-50 cm away from the comb, wet and cover the soil, and then cover the soil after proper watering if the weather is dry. It is easy to suffer from multiple frustration when mango plants are used for many times, such as cracked gum, brittle branches, short branches, curled leaves, flower shortening and so on. Therefore, it is recommended to reduce the use by half every other year, combined with foliar fertilizer.
