Why can Toona sinensis buds be sold so expensive?

Toona sinensis, a kind of plant called "vegetable on the tree", is usually listed around Grain Rain every year. Toona sinensis buds are used as vegetables to make various dishes. At present, through protected cultivation, the market time is advanced, and its value is not as good as that of naturally germinated Toona sinensis. Why is the price of Toona sinensis so high now?

At present, the yield of Toona sinensis planted in the reserve is very low. Let's think about it. The buds on the branches are too big to sell, so they can only be broken off when they are tender, and there is no yield. Although it doesn't cost much to use a greenhouse, compared with open-air planting, there is still some investment, and it is normal for the price to be higher. Toona sinensis should be picked before dawn and then sold to buyers as soon as possible. Farmers have worked hard, and it is more expensive not to sell. I'm sorry for their hard work.

(1): Before planting Toona sinensis, a certain amount of farmyard manure (livestock manure) of about 4000 kg, nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, urea and compound fertilizer should be put into the field together in a certain proportion, so that Toona sinensis seedlings can grow better.

(2) Pest control: The main pests of Toona sinensis are Acacia, Toona sinensis caterpillar and Cerambycidae. Spraying trichlorfon 800 times can kill them.

(3) Pruning: June-July every year is the busy time for pruning Toona sinensis trees, and pruning is also the busiest time of the year. However, in order to make Toona sinensis grow better, these works must be done. After pruning, add fat foliar fertilizer by spraying liquid for 5-7 days to help Toona sinensis be damaged during pruning.
