Effect of Different Irrigation Methods on Plant Growth of Pepper in Greenhouse

In order to determine the effective irrigation method in the greenhouse,in the paper,experimental research is carried out in the greenhouse adopting the drip irrigation,the tube irrigation,the furrow irrigation respectively.Moreover,it analyzes the effect of different irrigation methods on plant growth of pepper.The result shows that different irrigation methods were not related to the plant height、diameter of pepper significantly.On the same stage by measuring chlorophyll content,drip irrigationtube irrigationfurrow irrigation and chlorophyll content and photosynthetic are positive correlation.With significance α=0.1 for the yield variance analysis shows that the different irrigation method of a significant impact on yield,drip irrigation yield is the highest,followed by tube irrigation and furrow irrigation is the lowest.Compare to the different irrigation method,the water productivity of furrow irrigation、drip irrigation、tube irrigation are 16.17,35.13 and 31.59 kg/m3.So the drip irrigation is more preferable for pepper production in the greenhouse.
