Abstract: Tea plantation in the hilly regions of Hunan Province has many advantages including various well-known tea brands,low production cost,and high tea output.However,tea gardens in hilly regions also have many disadvantages,such as infertile soils, seasonal droughts,and simple ecological structure,which decrease tea quality and benefits.Field experiment results show that straw cover in tea plantations can effectively improve soil fertility and increase surface soil water content during tea growing periods,March to October.Cover with outer screen shadings during hot-dry seasons of summer and autumn can ameliorate tea garden illumination,temperature and water,promote accumulation of amino acids and chlorophyll in tender tea apexes,and increase the production of high-quality tea.In addition,complex artificial ecological tea plantations in hilly regions improve eco-environment and increase amount of natural enemy to restrain the occurrence and development of primary pests.Thus cultivation of complex artificial ecological tea,planting deciduous arbor between tea rolls,and complete straw coverage in the hilly regions of Hunan Province are recommended.
