Citrus is a perennial fruit tree Proper shaping and pruning can make the crown skeleton compact and firm, with strong bearing capacity, and the crown is ventilated and transparent, forming a three-dimensional effect. Reasonable pruning of high-yield trees can reduce the number of spraying. Natural round head and natural happy citrus trees are usually natural round head and natural happy. Secondly, pomelo and orange with strong growth potential can also adopt the improved trunk shape of the middle trunk in the sparse planting garden. The natural round head shape and natural happy shape are close to the natural growth state. The height of natural round-headed trunk is 30~40 cm, and there is no obvious central trunk. The number of main branches is 3~5, and the included angle between main branches and trunk is 30 ~ 45. There are 2~3 auxiliary main branches on each main branch, and the crown is compact and full, showing a round head shape. The difference between natural happiness and natural circle is that the number of main branches is small, generally there are three main branches, which are relatively open and evenly distributed, happy but not exposed, the crown surface is concave and convex, and sunlight can penetrate into the crown. Generally, sweet oranges and tangerines mostly adopt natural round heads, while satsuma oranges have higher requirements on light conditions and mostly adopt natural shape-pleasing.
