Analysis on Sunshade Net Covering Modes in Tea Garden in Guizhou

There are three main ways of covering sunshade net in Guizhou tea garden:direct coverage,tunnel coverage and greenhouse coverage.Among them,direct coverage shows the lowest cost,the least labor force and the simplest operation.But the buds and leaves on the canopy surface under direct coverage are easy to be lost or burned,which results in low output and reduced tea quality.The greenhouse coverage shows the highest cost and labor force,and the most complex operation.But the buds and leaves are less hurt,the output is relatively high,and the tea quality is improved.The one-time investment of tunnel coverage is less than the greenhouse coverage.However,in practice,it costs more labors and results in medium quality.
