The key points of the latest management of grapefruit trees

Grapefruit is a fruit of the genus Citrus, which is equivalent to an expanded version of oranges. There are many varieties of grapefruit. Now the planting area of various varieties is also getting wider and wider, but no matter what variety it is, it needs to have a good management method. Most of the time, planting failure is caused by poor management of fruit farmers, so how to manage grapefruit trees? Today, the editor brings you the key points of the management of pomelo trees. Let's have a look!

1. Seedling management

It is very important to manage the seedling stage after grapefruit planting. Grapefruit seedlings like fertilizer, but should not apply too much fertilizer, and should follow the principle of a small amount and more application. And in order to improve the growth rate of seedlings, nitrogen fertilizer should be applied at least twice a month in the seedling stage. And some crops can be properly planted in the distance between seedlings to improve the looseness of the soil, and it can be turned deep into the soil as fertilizer after maturity. To observe the growth of young trees, it is necessary to cut off some overdense and long branches in time, erase redundant new buds, promote ventilation and ventilation in orchards, improve photosynthesis and strengthen the growth ability of fruit trees.

2. Cultivate the soil by ploughing.

Ploughing and soil cultivation is an indispensable work in the process of planting grapefruit. Intertillage can improve soil permeability and promote soil looseness. It speeds up the decomposition of various substances such as water, air and fertilizer, and mid-tillage can effectively get rid of orchard weeds. Getting rid of weeds in orchards can not only prevent competing with fruit trees for nutrition, affect the growth of grapefruit, but also reduce the incidence of diseases and insect pests. The number of intertillage should not be less than 3 times a year, and it should be carried out once in autumn, winter and spring. Pay attention to the depth when ploughing to prevent damage to the roots of grapefruit trees and affect nutrient absorption and growth.

3. Reasonable topdressing

Grapefruit trees, like apple trees, are taller and more luxuriant, so there is a great demand for fertilizer in the growth process of grapefruit. Therefore, in our management, we must ensure sufficient nutrients for the growth of grapefruit trees, and the manure of pomelo topdressing can use mature farm manure. It should be noted that chemical fertilizers such as chlorine fertilizer should not be used during the flowering and fruiting period of the grapefruit tree, otherwise it will reduce the flowering and fruiting rate of the grapefruit tree. The first fruit of pomelo tree topdressing times should not be less than three times, because the consumption of nutrition is more, and then according to the age of the tree and various factors of soil conditions reasonable topdressing.

4. Shaping and pruning

When the grapefruit tree is young, the top growth ability is relatively strong. The top of the branch will show a phenomenon of upright growth, which can easily lead to a particularly obvious demarcation of the trunk of the tree. The branches in the young tree stage should not be too strong and too prosperous, because the bearing capacity of the tree is not enough, the branches will sag and bend, resulting in poor permeability. However, most of the fruit-bearing branches of the grapefruit tree are in the inner chamber, so it is extremely disadvantageous to the hanging fruit rate. Therefore, we should timely gather in the outer branches and leaves, control in the degree of sparse, the top branches should not be too long, should be re-pruned, internal branches do not need to be trimmed, so as to improve the ventilation and permeability of grapefruit trees.

The above is a brief introduction to the key points of grapefruit tree management. it should be noted that the shaping and pruning of grapefruit trees no matter which growth stage of grapefruit trees. Attention should be paid to it, because it is a key factor affecting the yield and fruit quality of pomelo. That's all for today's introduction. This article is for reference only.
