AI Technical Summary

Problems solved by technology

It is estimated that, based on the tree age of 5 years, about 50kg of young leaf buds are produced per mu of Hawthorn forest. The large planting cost has not been compensated, resulting in the phenomenon of fruit farmers increasing production but not increasing income
At present, the planting area of ​​hawthorn in Guangxi has reached 300,000 mu. The use of hawthorn is concentrated in the leaves of hawthorn as Chinese medicinal materials and the fruit of hawthorn as medicinal materials and food raw materials. However, the nutritious leaf bud by-products produced by "topping buds" , but it has not been utilized, and these leaf buds are basically discarded, wasting resources
[0007] In addition, at present, there is no relevant report about making black tea from hawthorn leaves
