Can you grow mangoes in Weifang, Shandong?

Mango is not suitable for planting in Weifang, Shandong. The temperature is too low, the growth is slow, and it is easy to freeze to death in dry and cold winter.

Analysis and explanation:

Mango likes warmth and is not resistant to frost. The optimum growth temperature is 25-30℃. When the temperature is lower than 20℃, the growth is slow. When the temperature is lower than 10℃, the leaves and inflorescences stop growing, and the nearly ripe fruits suffer from chilling injury.

The average annual temperature in the producing areas with normal growth in China is 19.8-24. 1℃, but the average annual temperature is 2 1-22℃, and the highest temperature in Leng Yue exceeds 15℃, and there are many areas with almost no frost all the year round.

The effective temperature for mango growth is 18-35℃, the suitable temperature for new shoot growth is 24-29℃, and the average daily temperature for fruit setting and young fruit growth should be greater than 20℃.

Insufficient temperature, poor pollination and fertilization, and even inflorescence death or embryo abortion death.

When the temperature is higher than 37℃, the fruit of Copanawa will be sunburned; When the temperature is lower than 10℃, the growth of new shoots and new ears stops; When the temperature is lower than 5℃, seedlings, tender shoots and ears will suffer from cold; When the temperature is about 0℃, the shoots, shoots and peripheral leaves of seedlings and trees will be damaged or even died.

Young trees below -3℃ freeze to death, and big trees freeze seriously.

The average annual temperature in Weifang, Shandong Province is 12.3℃, and it is dry and cold in winter, ranging from-8 degrees to-4 degrees.

Therefore, it is easy to cause plants to freeze to death in winter in this area, and normal weather is not conducive to growth and fruit, which is not suitable for planting.

Training points:

The reproduction modes of mango can be divided into sexual reproduction and asexual reproduction.

Sexual reproduction is sowing the seeds of reproduction.

Asexual propagation includes grafting, air layering and cutting, and grafting is commonly used.

The best sowing time is the ripening season of mango from June to July, because the seeds are fresh and easy to come, and the survival rate after sowing is high.

Choose a flat or gentle slope with relatively flat terrain, abundant sunshine and shelter from the wind.

Sandy loam with deep soil layer, good drainage and rich organic matter is suitable for soil.

Attention should be paid to drainage in the whole border of mango nursery, because seedlings are afraid of soaking in water during seedling raising, and soaking for many days in a row may easily lead to stunting or death of seedlings.

In the whole border, according to soil fertility, decomposed organic fertilizer and calcium superphosphate should be applied as base fertilizer.

When sowing, the kernel should be upright, and the triangular planting method should be adopted, with the navel facing down. Flat sowing is not allowed, because it will cause irregular germination. It can germinate about 7 days after sowing.

The suitable row spacing is 10× 15cm, and the covering soil is about 2cm. Water once every 1-2 days after sowing to keep the survival rate moist. If it is treated by flooding, because of the uneven terrain, the wet and dry conditions are often inconsistent, and some seedlings will be soaked.

After germination, it can be topdressed once or watered once with 2% urea aqueous solution, and can be used as grafting rootstock after about 6-9 months.

Colonization:

It is best to plant in June-August. If there are irrigation conditions, it can also be planted in the southwest and south from September to June at 65438+ 10.

If bagged seedlings are used, they can be planted in non-arid areas from March to May.

It is best to plant it on cloudy days or before it rains.

When planting bare-rooted seedlings, the root system should be extended; When planting seedlings in bags, you can't step on soil.

The planting depth should be equal to the surface of root neck soil. After planting, pour the root water and cover it.
