In rural areas, there are no people who specialize in planting Sophora japonica. Once introduced into the mountain forest, tree species naturally reproduce into forests. In rural areas, some people will plant one or two Sophora japonica trees, which grow faster and were used as agricultural tools in the old society. Not many people want to make money by selling Sophora japonica. Over time, the trunk of Sophora japonica is the root of people planting Sophora japonica. Since the economic benefits are poor, naturally no one wants to plant Sophora japonica.

The flowering of Sophora japonica is greatly influenced by temperature. It blooms early in places with low altitude and high temperature, but there are few Sophora japonica in plains, high altitude and low temperature in mountainous areas, and many Sophora japonica bloom late. Sophora japonica should be picked when it first grows and cooked at home. If it blooms, it won't taste good, so it will only take a few days to eat Sophora japonica.

Whether it is fresh Sophora japonica or dried flowers, if you want to sell money, this should belong to the category of local products or wild vegetables. Whether it is a physical store or an e-commerce network sales, it needs to have a certain scale and quantity. Otherwise, it is a small fight. Sophora japonica is harder than poplar, which is very troublesome to handle in furniture board factory, so the price is not high and the economic benefit is not good. In terms of wood utilization rate and economic benefits, Sophora japonica is much worse than poplar.

Picking is difficult. Sophora japonica is a big tree, its branches have thorns, so it is not allowed to climb and it is not easy to pick mechanically. It takes time and effort to pick Sophora japonica manually, but now the labor cost is high, and the picking cost will be high, resulting in high selling price. Although delicious and expensive, but after all, as a niche wild vegetable, people's demand is actually not so much. This dish, with or without it, is just the icing on the cake on the plate. Only popular in some places, affected by the flower season, it is useless to pick it. Moreover, it is not cost-effective to spend a lot of money on labor, and it is also prone to fall accidents. If you count the manpower and time of picking Sophora japonica flowers and then processing them, it is not cost-effective. Nowadays, people who do this kind of thing are usually old people.
