Postharvest pruning of mango trees

Mango is a common fruit in life, it belongs to subtropical fruit, many people may have eaten mango, but do not know much about the growth and cultivation of mango. Let's get to know it with the editor.

Pruning principles for planting mango

The main results are as follows: 1. The upper heavy and lower light mango has the characteristics of stable and more fruit in the lower and middle part of the crown, so the middle and lower part of the fruit tree should be cut lightly and leave as many branches as possible, so as to provide guarantee for the yield in the coming year. After mango harvest, the branches from the upper part of the crown should be re-cut to control the plant height and enhance the light transmittance of the tree.

2. The inner heavy and outer light mango blossoms and bears fruit on the top bud of the autumn shoot, most of the color fruit hangs on the surface of the crown, only a few bear fruit on the inner chamber branch, and a few are stem flower fruit (easy to appear when the tree is older). Therefore, the surface of the crown should be gently cut to ensure the number of fruiting branches, and the inner branches should be re-cut to ensure that the tree is ventilated.

Pruning requirements for planting mango trees

The main results are as follows: 1. The inner chamber is bright but not empty through the heavy shearing at the top and inside, so that the inner chamber is brightened, but the inner chamber branches can not be completely removed. Properly retain new shoots with 1-2 moss, which may bear fruit in the bore, but be careful not to disturb other branches.

2. The surface is neat and layered, the external light shearing keeps the original appearance of the crown, and after the autumn shoot, the crown is neat. However, we should pay attention to let the tree have layers, and there should be a clear distance between the layers, so as not to affect the daylighting of the branches and leaves at the lower level, and leave room for the branches to fall after the fruit.

Specific operation steps of postharvest pruning of mango trees

Cut off a section at the end of the fruiting branch during or after fruit picking and let the top of the remaining branch draw out autumn shoots. For the fruiting branches that have been drawn out of the autumn shoots, the last nodes can not be cut off, only the residual fruit stalks can be trimmed. After pruning the fruiting branches, the extension of the tree can be controlled. All the dry and withered branches, drooping branches, disease and insect branches and delicate branches were cut off. Cut off or cut off the main branch or big branch at the top of the crown and retain the 1-2-year-old branch, which may hang fruit and then be cut off in the autumn of the second year. One of the branches that depend on each other in the inner chamber should be removed, the branches with good extension direction and ends should be kept, and all the branches that wind randomly should be cut off.

Make a careful pruning on the surface of the crown, cut off the delicate branches and extra new shoots (each branch retains 2-3 new shoots), and cut back a section of the branches that are fruitless and sprouting. Then look around the tree, and if it is too dense or does not show layers, cut off the branches from the inner chamber. Sweep the cut branches and leaves, transport them out of the orchard and burn them centrally.

Conditions for planting mango

1. Temperature. Mango trees require higher temperature conditions, and can withstand high temperature, but not cold. The suitable temperature for growth is 20-35 ℃, and stop growing when it is lower than 15 ℃. The young trees had certain freezing injury at 2-5 ℃, and serious freezing injury or death when the temperature was less than 2 ℃. The anther could not be cracked and pollinated when the anther was below 20 ℃, and the pollen grains could not germinate when the pollen grain was below 15 ℃. It germinated well when it was more than 25 ℃.

2. Moisture. Mango is very tolerant to Rain Water, but the flowering period requires drought and little rain. High and stable yield can be achieved when the rainfall reaches 750mm. During flowering and fruit setting period, heavy dew will seriously drop flowers and fruits, uneven dry and wet or excessive rainfall will cause fruit cracking. Drought in autumn and winter is conducive to flower bud differentiation and early flowering.

3. Light. Mango likes yang and fears shade, and sufficient sunlight for planting mango is beneficial to growth and fruit. the sunny leeward side blossoms early, bears more fruit, has good quality, less fruit in the crown with poor ventilation and light transmission, and poor quality.

4. Soil. Mango is not strict on soil, but it is better to use sandy loam or alluvial soil with good drainage and deep soil layer, and the pH value is between 4.4 and 7.5. the alkaline or alkaline soil is not suitable to plant mango, which is easy to cause element deficiency (potassium, zinc, magnesium, etc.).

For mango growers, mango tree pruning is also very important. Correct pruning can make mango trees grow healthier and produce more mangoes, so don't underestimate the importance of branch pruning, which will directly affect mango production.
