How to grow the latest mandarin

Ponkan, also known as mandarin, is a very popular fruit in the market in recent years, especially during the Spring Festival, the sales of Ponkan can be said to reach its peak. The pericarp of Ponkan is thicker, but easy to peel, fresh and sweet, and resistant to storage, and it has strong adaptability to the environment, has the widest planting area in the tropical climate, and has stable and high yield. So today we are mainly going to learn the planting techniques of Ponkan. Let's take a look.

1. Choose a place to build a garden

The main producing areas of Ponkan in China are Zhejiang, Guangxi, Hunan, Hubei, Jiangxi and Sichuan. Then the selection of garden needs to refer to the conditions of various planting sites. In general, it is required that the soil layer is deep, the soil is loose, the soil is rich in organic matter, sufficient nutrients, moderate acidity or acidity. Secondly, the orchard had better have a little slope to facilitate drainage. Of course, it should be close to the water source and facilitate irrigation. Finally, the transportation near the orchard should be convenient to facilitate the transportation and sale of mandarins.

2. Planting technology

Ponkan is usually planted from September to November, as well as in February and March every year. When planting, it is generally planted according to the spacing of four meters between rows and three meters between plants, and it can usually plant about 50 to 60 plants per mu. Dig planting holes before planting. The depth and width of the holes are 90 cm and 80 cm. After the planting hole is dug, pour about 40 centimeters of soil fertilizer into the hole, and then sprinkle 10 centimeters of fine soil into the hole, and finally plant. When planting, straighten the seedlings, then backfill with soil, compact the ground, and pour enough water.

3. Water and fertilizer management

In order to make Ponkan grow healthily and rapidly, it is generally necessary to use more organic fertilizer and fertilize it with inorganic non-and formula feed at the same time. In fertilization, it is mainly based on soil fertilization, combined with foliar fertilization. Generally speaking, the methods of soil fertilization are ring ditch fertilization, strip application, hole application, soil surface application and so on. During the period of young trees, ponkan should apply thin fertilizer frequently, mainly nitrogen fertilizer, combined with potash fertilizer and phosphorus fertilizer, at least five or six times a year. On the other hand, adult trees need to be topdressing four times a year, sprouting fertilizer is mainly manure and urine water, fruit protection fertilizer tooth decay is phosphorus and potassium fertilizer, strong fruit fertilizer is the same as fruit fertilizer, fruit picking fertilizer is organic fertilizer. At the same time, watering and drainage should be carried out reasonably according to the different growth periods of Ponkan trees.

4. Pruning and shaping

The pruning of mandarin trees is mainly divided into four stages. First of all, young tree pruning, mainly light pruning, retaining the main branches, and so on when the branches grow to a certain length, gently cut short, adjust the growth balance between the trunk, and remove dense branches. The citrus trees that bear fruit at the initial stage continue to cut off the main branches at all levels, promote the growth of strong branches and erase the summer shoots. And through ring cutting and other measures to promote flowers. There is full fruit pruning, mainly pruning diseased branches, weak branches, withered branches, dense branches, old branches and so on, to maintain the current yield. Finally, there are aging fruit trees, we need to maintain the yield of fruit trees, then we need to replace the main branches and re-retain branches.

5. Prevention and control of diseases and pests

The most common diseases of Ponkan are foot rot and anthracnose. Foot rot is caused by poor permeability in the field, which can be controlled by carbendazim and methyl topiramate. Anthracnose is caused by partial application of nitrogen fertilizer or too much water in the field, as well as rising temperature, which can be treated with mancozeb and chlorothalonil. The main pests are mites, scales, aphids, leaf moths, longicorn beetles, bud maggots and other pests, pests are very frequent, we generally use low-toxic pyrethroids for poisoning, or use physical principles for trapping.

The above is the planting method of Ponkan, in the process of planting, we can also use bagging technology to control diseases and insect pests. If you want to know more details, remember to follow us and leave a message for the editor.
