Grapefruit is a favorite fruit for many people, especially in winter. The market prospects are very good. So many fruit growers will choose to grow grapefruit. However, the planting of grapefruit is prone to some diseases that affect the quality. What are the reasons that affect the quality of grapefruit?

What are the reasons that affect the quality of grapefruit?

I. yellowing and decline of leaves

1. Leaves are actually a very important part of trees. The main nutrients of the fruit are provided by leaves and trunks, the yellowing decline of grapefruit leaves will affect photosynthesis, and slowly the trunk will also produce a series of problems. Naturally, the pomelo is not good.

2. The yellowing of leaves can not provide rich nutrition for the fruit, resulting in grapefruit ripening ahead of time before the growth cycle, resulting in grapefruit of extremely poor quality. The sand skin disease of pomelo will leave black spots on the surface, which will greatly affect the appearance, resulting in not being able to sell a good price.

II. Ulcer disease

The canker of pomelo can not be ignored, it will form ulcers on the surface of its leaves and stems, if the serious fruit cannot be sold, then the problem of bursting generally occurs on honey pomelo, and it will form cracks in varying degrees at the bottom of the fruit. these are the main reasons that affect quality.

III. Soil acidification

1. In the case of using too much nitrogen, phosphorus and potassium compound fertilizer, it will lead to soil acidification, soil will form hardening, the root system of pomelo tree is difficult to stretch and can not produce more capillaries, and it is difficult to absorb sufficient water and nutrition to the trunk and fruit.

2. The lack of organic fertilizer and trace elements in the land will lead to unbalanced nutrition of the trunk, the fruit will absorb a large amount of nutrition of the trunk, lead to the overdraft of the trunk, and the reduction of beneficial microorganisms in the soil, and the grapefruit tree will slowly become a weak physique. It is difficult to resist the growth of pathogenic bacteria, resulting in a variety of frequent diseases.

Fourth, the nutrition of the tree is not balanced.

If the nutrition of the tree is not balanced, the grapefruit on the branches will burst and the production capacity will be low. At this time, you can apply more fertilizer or hang water for the trees.

Fifth, there is no reasonable cleaning of the orchard

There is no reasonable cleaning of the orchard before the fruit trees bear fruit, such as loosening the land in the orchard. Farm manure or an appropriate amount of organic fertilizer can be added in the process of loosening the soil to form a good environment for the later growth of fruit trees.

The grapefruit tree hangs too much fruit

Sometimes grapefruit trees hang too much fruit, the fruit needs a lot of water and nutrients, it will be extracted from the branches, if the underground roots can not be replenished in time, it will directly affect the normal growth of fruit trees. In the process of growing over the years, there will be a lack of trace elements in the soil, sugar is too low, then we have to timely and fruit trees to supplement the lack of nutrition.

Well, these are the reasons why the editor of Tuliu.com affects the quality of grapefruit. I hope it will be helpful to all of you. I also wish you all the cultivation of grapefruit can find the cause in time and deal with it.
