Technical points of increasing yield and improving quality of Spring Tea
Postpone light pruning: regular trimming of tea crowns is carried out from December to February of the following year. Practice has proved that, first, the branches are vulnerable to freezing damage after pruning; second, the overwintering buds are cut off, which delays the germination of spring buds; third, the accumulated nutrients in the crown branches of tea trees are cut off, affecting the sprouting ability and growing thick branches of spring buds, and finally affecting the yield and quality of spring tea. Therefore, the pruning time should be carried out after the frost period, and the first spring tea can be mined 30-40 days after cutting. Early topdressing: most of the conventional topdressing is in the first and middle of March, spring buds.

The pathogens of Gastrodia elata disease are mainly basidiomycetes other than Armillaria mellea in fungi, which infect the fresh and fungus materials of symbiotic Armillaria mellea and compete with Armillaria mellea for nutrients, which will not only inhibit the growth of Armillaria mellea and reduce the yield of Gastrodia elata. It will also directly infect the tuber of Gastrodia elata, causing Gastrodia elata rot soft rot (called tuber soft rot) or rot death (called tuber rot). Most of the disease is in bad environment, such as high temperature, high humidity, poor ventilation and so on, which is not conducive to the growth of Gastrodia elata, resulting in the yellowing of the tuber skin of Gastrodia elata.
