Favorable climatic conditions for planting mangoes in Tiandong County

What climate and where are mangoes planted? Look at those who want to grow mangoes.

Life habits of mango trees:

(1) temperature

Mango likes high temperature, not cold-resistant, and it is more difficult to avoid drizzling cold weather during flowering. The effective temperature of mango growth is 15-35℃, and the optimum temperature is 24-27℃. Only when flowering is above 20℃ can pollination and fertilization be normal. When the temperature is lower than 20℃, the anther will not crack and the pollen will not germinate, which will affect the results. Small trees can freeze to death at -3℃, and big trees will be severely frostbitten. Therefore, the local temperature is the limit that determines the suitability of mango planting. According to some data, the northern boundary of mango introduction in China is 27 43' north latitude (Pingyang, Zhejiang), but generally speaking, the Tropic of Cancer in China is the northern edge of mango economic cultivation. As for going further north, it depends on the meteorological conditions in this place and whether there are conditions for economic planting.

(2) Moisture

Mango is drought-tolerant, but not waterlogged. Generally, it can be planted in places with annual rainfall above 700 cm. Sufficient water will make the nutritional growth of mango too strong, which is not conducive to flowering and fruiting, and will also aggravate the breeding and harm of pests and diseases. However, if the soil is too dry, it will cause flowers and fruits to fall. Long-term drought and showers during fruit development can also lead to mango fruit cracking. Moderate drought in the critical period of flower bud differentiation is beneficial to stop the growth of branches and make flower bud differentiation. The environment with sunny weather, relatively little rainfall and irrigation conditions at flowering stage is an ideal planting area for mango.

(3) Lighting

Mango likes warm sunshine, and plenty of sunshine is very beneficial to the growth and fruit of mango. Strong sunshine, warm weather and low relative humidity at flowering stage are beneficial to pollination and fertilization. The fruit has high fruiting rate, bright color, rich fragrance and storage resistance. Northbound orchards are prone to diseases and pests because of poor light and low yield. 4. Soil mango is not strict with soil quality. Except the extremely barren saline-alkali soil, all types of soil can be planted from alluvial soil to latosol. Because mango is a deep-rooted fruit tree, it is required to be planted on a plot with deep soil layer, good drainage and low groundwater level. Because it is a mycorrhizal plant, the soil is required to be rich in organic matter and breathable, and the suitable pH value is 5.5-7.0. If the soil pH value exceeds 7.5 or is lower than 5, it will affect the growth and development of plants.

Mango planting technology needs to meet the following requirements.

A, mango requirements for temperature:

Mango, after all, is a tropical fruit and belongs to a warm-loving plant. Mango planting needs temperature, likes warmth, and is not resistant to frost and cold. The optimum temperature is 25℃~30℃. Below 25℃, the growth is slow; Leaves and inflorescences will stop growing below 10℃; When the temperature is lower than 5℃, the seedlings, shoots and ears are all cold. When the temperature is lower than 0℃, the upper part of the seedling, the ear, twig and peripheral leaves of the tree will be damaged, and even die in severe cases. Below -3℃, small trees freeze to death and big trees freeze badly. It can be seen that the temperature requirement of mango is still quite high, and the north is not suitable for planting. The temperature is about 27 degrees, which is suitable for growth. The temperature is too low and mango grows slowly, so it is suitable for planting in southern China such as Guangxi, Fujian and Guangdong.

Second, mango's requirements for soil

Mango has low requirements on soil, and can be planted in places with relatively low altitude. The sandy soil with deep requirements for soil, good drainage and slight acidity is most suitable for the growth of mango trees. It is suitable to grow on slightly acidic loam and sandy soil with deep soil layer, fertile soil and good drainage.

Third, the requirement of moisture.

Mango is suitable to grow in areas with rainfall 1000 to 2000 mm, and uneven rainfall in some places will also affect mango growth. In the flowering and fruiting period, insufficient rainfall and too little rain cause flowers to fall off, which is easy to lead to falling flowers and fruits; Too much rain can easily lead to poor pollination, and too much concentration can easily lead to rotten flowers and poor fertilization. In severe cases, it will bring pests and diseases, induce fruit diseases, and affect the growth and mango yield.

Fourth, the requirements of fertilization.

Mango has a great demand for fertilizer, so fertilization management should be done well at all stages, mainly organic fertilizer. About February, a certain amount of Zhuanghua fertilizer and Trim potassium dihydrogen phosphate fertilizer should be applied to promote ear growth and increase fruit yield. Strong fruit fertilizer and phosphorus-potassium compound fertilizer should be applied during the grain-filling period to ensure the demand for nutrition during the grain-filling period. When applying fertilizer to mango trees, dig holes 2~3 months before sowing. Apply farmyard manure to each pit about 30 kilograms.

Five, pruning and pest control

Prune mango trees properly from time to time to balance the nutrition of fruit trees. In spring, some dead branches and diseased branches should be pruned properly even if they are pruned, so as to adjust nutrient absorption and improve fruit setting rate. Strengthen nursing, especially in summer. If you find pests and diseases, you should consult agricultural stores for spraying in time. Pest control. Mango diseases include soot disease, and AIDS risks are AIDS, anthracnose and powdery mildew. It can be 700~800 times that of Tobuzin. After each new shoot is picked, it can be sprayed once in the fruiting period; Mango pests include poisonous moths, scarabs and night cicadas. And trichlorfon and insecticidal cream can kill 800 times each.
