Collection and processing Technology of Autumn famous Tea
(1) Tea picking. Pick and take lightly. The tea canopy with good growth and thick green leaves can be picked with fish leaves or no leaves. The tea canopy with poor growth and thin green leaves, especially the tea canopy with more fallen leaves and bone branches in the early stage, should be kept mainly, and the method of topping and leaf harvesting should be adopted in the later stage. In order to quickly restore the tree potential, conducive to the next spring tea harvest. (2) keeping fresh leaves. The temperature in early autumn is high, the climate is dry, and the water content of fresh leaves is less than that of spring tea. when transporting and storing, it is necessary to prevent the moisture of fresh leaves from spreading too quickly and dehydrating too much. The container of fresh leaves should be clear.

Control of Ligustrum lucidum
The damage of Ligustrum lucidum in Beihengshui once occurred, which caused the death of a large area of Ligustrum lucidum at that time. Through the research and control in recent years, good results have been achieved. The control experience is summarized as follows: PseudococcasConstock, also known as mulberry pink scale. Its eggs are generally laid between petioles and branches, oval, light orange, dozens of eggs concentrated into blocks, forming white floc oocysts. Three generations a year. The peak period of the first generation nymph is mid-late May, the second generation is mid-late July, and the third generation is 8.

In previous years, because the golden leaf privet has the advantages of easy reproduction, drought resistance, less diseases and insect pests, resistance to pruning, long golden leaf period and good scenery effect of large color blocks, it has been widely planted, especially for pattern ribbon modeling and large color blocks. However, due to the high planting density and inadequate maintenance and management, brown spot and fallen leaf disease occurs every year in the rainy season (August to September in Luoyang area), resulting in leaves falling one after another, new leaf buds can not be pulled out in time, and even plants die, seriously destroying the landscape effect. In view of this situation, we paid attention to Jinye in 2003.
