The latest course of mango planting and management techniques

Mango is one of the famous tropical fruits, which is very popular because of its delicate and sweet flesh, special flavor and high nutritional value. Mango also has the characteristics of wide adaptability, fast growth, long fruiting period and high economic value, so it enjoys the reputation of "king of tropical fruits". In recent years, the planting area of mango in the world has been expanding year by year, and the yield has also increased year by year. At present, after grapes, oranges, bananas and apples, it has become the fifth largest fruit in the world.

Choose a place to build a garden

1. Garden selection: mango orchard requires that the soil layer is thicker, the soil quality is not easy to solidify, there is no stagnant water, and it is close to the water source, so that it can be irrigated to ensure a bumper harvest during spring drought.

2. Planting density: according to climate, soil fertility and varieties, the planting specifications can be 4 meters × 4 meters, 4 meters × 5 meters and 5 meters × 6 meters.

3. Planting: the suitable planting time is from June to August every year. Choose cloudy or sunny days for planting, when planting, put the seedlings into a pre-prepared planting hole and then return to the soil, when planting bags, plastic bags must be removed before planting.

Orchard management

1. Irrigation and drainage

After planting, the seedlings need to be drenched and kept warm in the case of drought. Watering once every 7 to 10 days is appropriate to keep the orchard soil moist. Regular irrigation is needed during the flowering and fruiting period to ensure the moisture needed for flowering and fruit. If there is local stagnant water in the rainy season, it should be drained in time.

2. Ploughing, weeding and loosening the soil

The orchard requires weeding 4-6 times a year to keep the rhizosphere to weed. The shallow root circle should be loosened before late autumn to winter.

3. Coverage

Grass mulching can maintain water balance soil temperature, reduce the breeding of weeds, at the same time, increase soil organic matter, prevent consolidation, which is beneficial to the activity of root groups.

4. Deep digging and soil pressing,

At the crown drip line, dig fertilizer ditches that are 80cm long and 150cm long, 40cm deep and 50cm wide. Each ditch is pressed into 40-50 kg of grass, 10-20 kg of soil fertilizer and 0.5-1 kg of superphosphate.

5. Fertilization for fruiting trees

① is fat after fruit. Mainly organic fertilizer, combined with deep ploughing to improve soil. Each plant should also be increased by 0.5 kg of available nitrogen fertilizer.

② fertilizes the flower. The period of flower bud differentiation was from 11 to 12 months one month before flowering. Generally, ammonium sulfate or urea is 0.51kg / plant.

③ Xie Hua Fei. Add 0.5%-1% potassium hydrogen phosphate or potassium nitrate as extra-root topdressing when applying quick-acting nitrogen and potassium fertilizer or combined spraying in mango blossom.

④ strong fruit fertilizer. The fertilization time is from March to April every year. The amount of fertilizer applied this time accounts for 60% of the amount used in the whole year. The mixed ratio of N ∶ P ∶ K was 8 ∶ 1 ∶ 8. Combined with irrigation, it is beneficial to the water and nutrients needed for fruit expansion.
