Coverage under the condition of different photosynthetic characteristics of Chinese wolfberry Abstract: through the use of gravel, plastic film, such as wheat straw covers 3 different ways of photosynthetic characteristics of Lycium were studied. The results showed that four kinds of different treatments in order to deal with plastic film mulching on the Chinese wolfberry transpiration rate, stomatal conductance, photosynthetic rate, intercellular CO2 concentration in the best coverage to deal with wheat straw mulching secondary processing. The results of the study of large-scale cultivation of Chinese wolfberry provides a theoretical basis for the production of high-quality high-yield barbarum laid a good foundation. Key words: Lycium barbarum; covered way; photosynthetic characteristics; impact
