The planting method of these grapefruit trees must be known, so that you can harvest a few more years of fruit!

Now is the fresh season of sour and sweet and delicious grapefruit on the market, and it is also the happiest time for pomelo growers, but in order to achieve high benefits, in addition to the good market, the planting method is also very important. let's talk about the planting methods of grapefruit. Learning these can help you harvest more fruits for a few years!

I. A brief introduction to the grapefruit tree

1. Grapefruit is an evergreen tree of Rutaceae, which is also known as Wendan, Gui and Dou in some places. It is planted in the south of our country. The main producing areas of grapefruit trees are Guangdong and Guangdong, Fujian, Sichuan, Hunan and Zhejiang provinces.

two。 The grapefruit tree has green leaves all the year round, the leaves are broad-ovate or oval, its petals are milky white, there are sharp thorns on the branches, and the overall tree shape is relatively beautiful. So in addition to being planted as an economic fruit tree, it is also planted on both sides of parks, communities and sidewalks.

3. Pomelo tree can be cultivated as an economic fruit tree or as a landscape greening tree, and its grapefruit has many nutrients and low calories, which has the functions of invigorating the stomach and moistening the lungs, tonifying blood, clearing intestines and defecation, removing fire and relieving alcohol, and so on. even the peel of grapefruit can be used as traditional Chinese medicine.

II. Planting methods of pomelo trees

As an economic fruit tree, the planting method is particularly important, so let's take a good look at the planting method of grapefruit tree.

1. Grapefruit trees can be planted by grafting and striping, of course, it is also possible to use seeds, but it takes too long for seeds to bear fruit, so it is generally not recommended for fruit growers to use them. Grafting is usually used from March to early April every year.

two。 Before planting, grapefruit trees should first apply basic fertilizer (preferably stratified), the amount per mu should not exceed 10,000 kg, in the top layer of fertilizer, cake compost, compost and so on. The planting density of pomelo trees should not be too high, because its growth is too strong and the crown is too dense to be conducive to growth, so there are about 35 to 45 trees per mu (depending on the topography of the planting site). In addition, it is better to plant grapefruit trees on cloudy or sunny evenings in March and November.

3. The root system and absorption capacity of young grapefruit trees are not complete, so it is necessary to apply a small amount of fertilizer many times, and each time the fertilizer is not too thick, thinning is beneficial to its growth. Organic nitrogen fertilizer is the main fertilizer (mature human and animal urine manure, cake fertilizer and appropriate amount of urea).

4. Adult trees should be fertilized at least three times a year, including budding fertilizer, strong fruit fertilizer and fruit picking fertilizer. Budding fertilizer was applied at the beginning of March, strong fruit fertilizer could be applied twice in June and August, and fruit picking fertilizer could be applied in November. Timely application of appropriate amount of fertilizer to the grapefruit tree can not only achieve high quality, high yield and stable effect, but also help the grapefruit tree to bear fruit early and harvest more fruit for several years.

5. In addition to fertilizing the grapefruit tree during its growth, it should also be shaped and pruned at different stages. After planting in the young stage, cut off the excess branches, leaving only three or four strong branches on each main branch, and there should be a proper interval between each branch; the grapefruit tree should also be pruned in the fruiting period, but as long as the long branches and dead branches of diseases and insect pests are cut off, the overdense branches can also be cut off. The lateral branches of the crown for 3-4 years can be cut off half a year before the old tree stops growing. There is no need to retain leaves on the crown. Generally, the old tree can recover its fruit after a year or two.

6. Grapefruit trees are vulnerable to Huanglong disease, canker, scab, anthrax and other diseases in the process of growth. Qingyuan can be used to cut off diseased branches and leaves and burn them on the spot, of course, the most important thing is to prevent them in advance and spray the garden and fruit trees with corresponding medicine. in addition, red spiders, rust tick lice and citrus leaf moth and other pests should also be prevented and controlled.

The majority of fruit farmers should be reminded that it is best to consult experienced farmers or consult relevant agricultural planting technicians when controlling diseases and insect pests with pesticides. They must not spray pesticides blindly to affect the growth and fruit of grapefruit trees.
