The best time for mango tree pruning what fertilizer should be applied to mango tree

Mango is very common in our life, and it is one of the fruits with rich nutrition and delicious taste. Although people are familiar with its efficacy, because it is a tropical plant, many people do not know much about its contents during its planting period. To be fruitful, proper pruning and fertilization are essential.

The best time for mango tree pruning

Generally speaking, it should be pruned from the harvest time, the larger branches should be pruned, the weak branches should be used as the head, and the overdense branches should be thinned to weaken the top advantage. For those branches with moderate growth rate and a variety of long branches, their growth can be slowed down to ensure that the mother branches with good fruit can be formed. At the same time, in the process of pruning, attention should be paid to the cultivation of branches to increase the grade of branches, so that the growth of branches can be more exuberant.

Pruning and plastic surgery should also pay attention to control the time, generally speaking, pruning is mainly to inhibit the growth of branches, in order to promote flower bud differentiation. The new shoots should be removed properly, not only to make the mango tree more beautiful, but also to make the mango tree have higher fruit yield and higher fruit quality. For example, in the process of pruning, it takes about one month from the end of pruning to the first hair. if the time of pruning is controlled in time, nutrition can be controlled in time and the growth of secondary shoots can be inhibited.

What fertilizer should be applied to mango trees?

First, the application of post-fruit fertilizer (June-early July): post-fruit fertilizer is the focus of fertilization throughout the year, accounting for 70-80% of the total amount of fertilizer applied throughout the year, the main purpose is to promote autumn shoots, restore growth, and lay a good foundation for next year's results. Mainly available nitrogen fertilizer and organic fertilizer, 30-50 kg organic fertilizer per plant, 1-1.5 kg urea and 0.5 kg compound fertilizer were applied after fruit picking and pruning.

The second is to apply flower-promoting fertilizer (September-October): the normal flower bud differentiation of mango is usually from November to December, and the flower bud differentiation promoted by chemicals can be earlier than October. Therefore, the flower-promoting fertilizer should be applied before the end of the rainy season, mainly potash fertilizer, 1-1.5 kg potassium nitrate per plant.

The third is to give thanks to flower fertilizer: mango flowering will cause a lot of nutrient consumption, so quick-acting nitrogen fertilizer should be applied once during flowering, and 0.5-1 kg of urea or potassium nitrate can be applied to each plant. Urea or potassium nitrate can be mixed with water into 0.5-1% fertilizer solution to spray leaves and fertilize outside the root to supplement nutrients.

The fourth is to apply strong fruit fertilizer: when the mango blossoms for about 30 days, the young fruit grows rapidly. In order to reduce fruit drop, urea and potassium nitrate are applied to each plant by 0.5-1 kg, or 600-fold solution of biotin is sprayed, once every 10-15 days, 3-4 times continuously.

Matters needing attention in mango fertilization

1. The root system of young mango trees is small, the number of fibrous roots is small, and the distribution is shallow, so fertilizer should be fertilized frequently and applied thinly. Water and fertilizer should be applied in times of drought. At the same time, combined with spraying new high fat film to improve the utilization rate of effective components of fertilizer.

2. Fertilization should not be close to the trunk, but the dripping line outside the crown, and the effect of evenly distributed hole application is good. The amount of fertilization can be adjusted according to the situation of soil fertility and growth.

In addition, Huawang No. 2 was used in the period of flower bud differentiation of mango to promote flower bud differentiation, adjust the nutrition conversion rate and balance the year thoroughly.

3. Young mango trees can appropriately increase a little nitrogen, and the fruit trees have a better effect of applying some organic fertilizer. In addition, Zhuangguotieling was sprayed once before flowering, young fruit stage and fruit expansion stage of mango to thicken the fruit pedicel and increase the amount of nutrient transport. Prevent falling flowers, falling fruit, cracking fruit, stiff fruit and abnormal fruit, making the fruit beautiful in color, beautiful in shape and good in taste.

Mango seedlings can bear fruit in a few years.

The reproduction methods of mango can be divided into sexual reproduction and asexual reproduction. Sexual reproduction is seed sowing propagation, and asexual reproduction includes grafting, air striping and cuttage. It takes a long time for mango to sow and reproduce, and it may not blossom for ten years. However, the grafted mango trees can bear fruit in 4-7 years, and some early-maturing varieties can bear fruit in 3-5 years.

About the mango pruning method and fertilization method first introduced here, I hope it will be helpful to everyone. Proper pruning of mango plants is very beneficial, which can reduce the loss of nutrients and increase the yield.
