Winter management of tea trees
The main results are as follows: 1. Spray the whole body of tea tree with 0.4-0.5 Baume stone sulfur mixture to seal the garden.
2. For hole application or furrow rotten cake fertilizer 150kg, or tea special compound fertilizer 100kg, it is required to finish the application of base fertilizer in November.
3. Combined with fertilization, the weeds on the edge of the garden can be removed and the overwintering habitat of pests can be reduced.
4. Good varieties should be selected in the tea garden, such as deep trench, deep application of basic fertilizer, double-row single-plant planting, low hole cultivation, low fixed cutting, and strive to finish planting this winter and next spring.

A New Technique of Tea Short Cutting
At present, the asexual propagation of tea plant mainly adopts the method of short ear cutting with bed surface paved with subsoil. Although this technology can effectively reduce the disease and grass damage in the breeding process, it restricts the breeding and popularization of tea varieties to a great extent because of its large workload and high investment cost. In recent years, we have put forward a simple, reliable, labor-saving and material-saving cuttage technology with no soil through a large area of experiments. The production cost of this technology is only 300 yuan per mu. It not only saves cost compared with the traditional spreading of soil, but also the survival rate of cuttage can reach about 85%.
