The main value of Huanghua pear
Wood is very stable.
The wood of Huanghua pear is extremely stable, and it does not deform, crack or bend in hot and cold weather. It has certain toughness and is suitable for making all kinds of special-shaped furniture, such as three legs. Its bending degree is large, but Huanghua pear wood can be made, and other wood is difficult to be competent. The main producing area in Huang Huali is Hainan Island, where natural resources are almost exhausted and there are no natural forests. Now there are many artificial forests in Hainan, Guangdong, Guangxi and even Fujian. However, despite the rapid growth in Huang Huali, the growth of heartwood which can be used to manufacture household appliances is quite slow. Within ten years, there is almost no heartwood on the tree. With the growth of trees, the heartwood gradually becomes larger, and it basically takes more than 4 to 50 years to reach the trees that can make utensils.
