What are the planting conditions of sweet mango in Vietnam?

Orchard should be built in a relatively open place with good lighting conditions, and the location should be far away from strong winds. You can't choose a rainy place, and the ecological environment around the mango garden is better. When choosing land, soil should also be considered. The soil should be fertile, loose and breathable, with good drainage and water retention, and the organic matter content should not be less. If the planting scale is large, traffic and terrain factors should be considered when selecting and dividing orchards. If the planting scale is small, it can be divided according to the specific situation.

2. Reclaim wasteland

After the land is selected, weeds and sundries on the land should be removed. If you choose sloping land, you can plant it in terraces, and if the land is relatively flat, you can dig ditches for planting. Land reclamation should be comprehensive and not perfunctory. The whole reclamation project should be carried out in two stages. The depth of the plow should reach 40 cm. It is best to soften the soil. Before planting, the land should be dry for a period of time.

3. Tree species selection

It is best to choose varieties with high yield, early maturity and strong disease resistance for cultivation. When selecting tree species, we should also consider the sweetness of fruit and the aesthetic appearance, which will affect the economic benefits of growers. Tainung no.,Ivory Mang, Wang Feimang and Four Seasons Honey Mang are all good choices.

4. Planting time and density

Spring from March to April is the most suitable time for colonization. At this time, the survival rate of planted plants is very high. The planting scale is generally 3-3.5mx4-4.5m, and it is best to plant about 45-55 mango trees every 667m2.

5. Planting method

Dig planting holes according to planting density. When digging a planting pit, the topsoil and subsoil shall not be put together. The planting hole is 80 cm wide, 70 cm deep and 60 cm wide at the bottom. The size can be changed from10 to 20 cm as required. It is best to use organic fertilizer and phosphorus and potassium fertilizer as base fertilizers, in which phosphorus and potassium fertilizer are auxiliary fertilizers. Add 25 kg of decomposed organic fertilizer and 0.75 kg of phosphorus and potassium fertilizer to each planting hole, then put the backfill soil into the hole and mix it with the base fertilizer evenly. The backfill depth is related to the nodule size of mango seedlings, and it should be noted that the soil surface after planting is higher than the original soil surface, preferably higher than 15~20cm. When planting, the root nodules of mango seedlings should not be loose. When planting, the marriage interface can be slightly higher than the ground. After planting, press the soil well and inject fixed root water into the soil to ensure that enough water is provided before the soil survives.

6. Orchard management

Pay attention to water and fertilizer and intercropping weeding. Mango seedlings should not only be given enough water before survival, but also be watered more when the weather is dry and pay attention to drainage in rainy season. In the early stage of mango seedling growth, nitrogen fertilizer was mainly applied, and phosphorus fertilizer and nitrogen fertilizer were applied in the middle stage. The amount of potassium fertilizer should be increased when mango grows to flowering stage and mixed fruit stage.

7. Tree management

Attention should be paid to timely and moderate pruning of mango trees, especially in the young stage of mango trees, which can improve the quality and yield of mango. When the tree grows to 1 m, it usually needs pruning, mainly to determine the main branches and lateral branches of the tree for subsequent maintenance, and also to promote the germination of auxiliary branches in order to bear more fruits.

8. Pest control

These diseases mainly control anthracnose and stem rot which are harmful to mango growth. It is best to choose disease-resistant varieties before planting, then clean the orchard frequently, weed in time and prune the fruit trees properly. The water solution of "Nongkang 120" can be used for plant spraying and disease control after being diluted by 2500 times. Pests mainly prevent the invasion of thrips and red spiders. Chrysanthemum EC can be diluted 2000 times and sprayed.
