Durian is a pure tropical crop, and its phenological characteristics are that the average daily temperature is above 22℃. Frost-free areas can be planted, and parts of China, Hainan and Yunnan provinces can be developed. ?

Because durian can only grow and bear fruit in the high temperature climate all year round, even in the equatorial region, in the highlands above 600m above sea level, durian can not be planted and bear fruit because of the temperature drop.

2. Planting method

Seeds are often used to cultivate durian, but the genetic variability of durian is great. Each seed may produce ten kinds of fruits with different qualities, and inferior durian can produce excellent varieties.

Planting height: 30~40 cm, the planting distance is 3m×5m, and base fertilizer, soil miscellaneous fertilizer and appropriate amount of lime are applied as base fertilizer. It can be planted all year round, and it is best to bring native seeds.

Fertilization management: Fruit trees should be fertilized/kloc-0 times a year, that is, spring budding fertilizer, summer fruit swelling fertilizer and pre-harvest fertilizer, especially fruit swelling fertilizer. Deep application of organic fertilizer after fruit harvesting.

Shaping and pruning: due to vigorous germination, attention should be paid to shaping after planting 1~2 years, and fruits should be pruned in time after picking to maintain a good tree shape.

Matters needing attention

1, soil

Durian is a tropical fruit, and the choice of planting location needs to be considered in many aspects. The first thing is to consider the climate of the planting area and other fields, so soil selection is also a key point. Because durian needs more nutrients for its growth, it needs to be selected in the area with rich soil fertility.

Secondly, the permeability of soil must be better, and the irrigation and drainage system should be better, preferably the plot with loose upper soil layer and thick lower soil layer, so that the survival rate of durian planting will be greatly improved.

2. Temperature

The growth of durian needs a lot of heat, so the temperature in the planting area is relatively high. It is best that the temperature is relatively stable all year round, with no obvious seasonal variation. The optimum temperature for durian growth is generally around 25 ~ 30℃.

The lowest temperature should not be lower than 10℃, otherwise the durian tree will stop growing or even freeze to death. So in some places in China, although durian is planted, the low yield and quality are mostly caused by temperature.
