Sunlight Greenhouse Sweet Peppers Under Different Irrigation Way Moisture Content Effect Research

This paper take the party irrigation theory as the guidance, with the research about sunlight greenhouse sweet peppers, in the seep irrigation, drip irrigation and furrow irrigation modes under the way the moisture content effect to conduct the experimental study.1. In the three modes, on the total yield, the seep irrigation is first, the second is drip irrigation, the last is furrow irrigation. In the earlier period of gather harvest, about gather harvest output the first is seep irrigation, the drip irrigation is similar to the furrow irrigation, but the former is a little larger. In the middle period ,the size order maintains consistent with the earlier period, The disparity reduced obviously between the drip with drip irrigation, and both of them are obvious much larger than furrow irrigation. In the late period of gather harvest, furrow irrigation's is the largest, the seep irrigation is lager than drip irrigation.2. The total irrigation water of the three irrigation modes, about the total irrigation water quantity: furrow irrigation's>drip irrigation's >seep irrigation's. On the side of average water irrigation quantity in one day, the max value of water irrigation quantity of the furrow irrigation mode is obvious larger than the drip irrigation's and seep irrigation's, the seep irrigation's a little larger than drip irrigation's.3. About the moisture content and moist scope of each soil ground of seep irrigation compare more relative stabilization than the furrow irrigation's and the drip irrigation's above 40cm soil ground. About the moisture content of 30cm soil ground, seep irrigation's is obviously is higher than the furrow irrigation's and the drip irrigation's; the drip irrigation's is lower than the furrow irrigation's, but the change is stable on overall.4. The of the plants have not obviously difference in the earlier period of transplant in the three irrigation, in the middle period of growing, the height of the plants with drip irrigation is much higher than seep irrigation and furrow irrigation continuously, and the furrow irrigation's is higher. In the late of growing, the furrow irrigation's height surpass slightly than the drip irrigation's height, the seep irrigation's is lower than others.5. About lamina chlorophyll content and photosynthesis speed, seep irrigation is obviously superiority than furrow irrigation and drip irrigation, the difference is not obvious between seep irrigation and drip irrigation on the transpiration rate, but them is obviously higher than furrow irrigation. When the seep irrigation in obtains in the same level photosynthesis product, the consumption water is fewer than drip irrigation and furrow irrigation, therefore achieve the saving water goal.
