The Effects Of Infiltration Irrigation On The Growth And Yield Of Tomato & Cucumber In Greenhouse And Vinyl House

Infiltration irrigation is a new water-saving irrigation technology, and zip fasteners pipes have traits of great capacity and are not easily jammed. This experiment took tomato and cucumber as the objects in the research to study the changes of growth and yield of plants under different treatments, which infiltration irrigation pipes were placed in different depths and distance, the results showed that:1 Infiltration irrigation can create good condition for growth of vegetables in greenhouse and vinyl house.The trends of air relative humidity and temperature are basically consistence under treatments of infiltration and drip irrigation under mulch film in greenhouse and vinyl house, that of infiltration irrigation are higher than that of drip irrigation under mulch film. The soil temperature in different time performance different, but all are lower than that of drip irrigation under mulch film. The soil temperature of the treatment whose pipes were placed in the depth of 25cm and distance of 60cm is highest among all treatments. The air relative humidity increases much more than that of drip irrigation under mulch film treatment; the temperature of infiltration irrigation descends less than that of drip irrigation under mulch film treatments.2 Infiltration irrigation can improve the physical properties of the soil and increase the activity of toots.Compared with drip irrigation under mulch film, the infiltration irrigation treatment can reduce the soil bulk density and increase soil porosity. The activity of roots of tomato and cucumber express out "low-high-low", but that of infiltration irrigation is good. In a word, infiltration irrigation can improve or not destruct the soil construction and promote growth of vegetables and prevent premature senescence.3 Infiltration irrigation can promote the growth of tomato and increase the yield of tomato.The treatments whose pipes were placed in different depths have little effect on the growth of tomato, and have significantly different on the yield of tomato. The treatment that the pipes were placed in depths of 35cm can increase the yield of tomato, especially the early yield. The treatments that the pipes were placed in different distance have little effect on the growth of tomato and have influence on the yield of tomato. The treatment whose pipes placed in distance of 60cm can increase the early yield of tomato. The effects on growth andAbstractthe yield of tomato have little different. The treatment whose pipes were placed in depth of 35cm and the distance of 60cm are best.4 Infiltration irrigation can increase the yield of cucumber.The effects on growth of cucumber varied with different treatments. The treatment which pipes were placed in different depth has not significant difference on yield of cucumber, but the treatments whose pipes were placed in different distance have significant difference on the yield of cucumber. The yield of cucumber are highest under treatment whose pipes were placed in depth of 60cm. Compared with drip irrigation under mulch film, infiltration irrigation can increase the yield of cucumber. The treatment which pipes were placed in depth of 35cm and distance of 60cm are best.5 Compared with drip irrigation under mulch film, infiltration irrigation has little effect on quality of tomato and cucumber.
