| 【目的】为探究不同滴灌带布置方式对黄金梨生长及水分利用效率的影响。【方法】农田试验处理共有4个，分别为地面单行（CK）、地面双行（T1）、地下双行（T2）、地面环状（T3）。分析不同处理对新梢、果实日增长量、果形指数、产量、品质、耗水及水分利用效率的影响。【结果】结果表明：T2处理的黄金梨产量、水分利用效率均高于其他处理；T3处理的新梢长势、果实日增长量、产量及水分利用效率均高于CK、T1处理；T1处理的新梢长度、果实日均增长量均高于CK处理，产量较CK处理降低了4.88%，但总耗水量较CK处理降低了46.92%，水分利用效率提高了40.08%。；滴灌带布置方式对果形指数、品质的影响不显著。【结论】从增产节水的效益考虑，地下双行滴灌带布置方式最优。 |

| Abstract: 【Background】Water resource is a key factor that restricts the survival and development of human beings, and among the main uses of water resources in China, agriculture is one of the giants. According to the latest water resources bulletin of 2018, agricultural water use accounts for 61.4 percent of total water use. It has become an inevitable trend of China's agricultural development to study water-saving irrigation technology to improve the efficient utilization of irrigation water and develop water-saving agriculture. As a kind of modern micro irrigation technology, drip irrigation on water saving, increasing production, improving soil properties play a very important role, is now widely applied in the production of high economic value of crops. Through literature review, it was found that different drip irrigation belt arrangement also had different effects on crop WUE. But the current studies of drip irrigation belt arrangement more focus on crops, the fruit trees should be how to carry out scientific and reasonable irrigation belt arrangement in order to improve the water use efficiency to obtain higher economic value of fruit of research are relatively few. Therefore, this project selected the 8-year-old golden pear as the material to carry out the experiment.【Objective】In order to explore the effects of different drip irrigation belt arrangements on the growth and water use efficiency of golden pears. 【Method】There were four field test treatments, namely, ground single row (CK), ground double row (T1), underground double row (T2), ground ring (T3). The effects of different treatments on the daily growth of new shoots and golden pears, fruit shape index, yield, quality, water consumption and water use efficiency were analyzed.【Result】The research results showed that the yield and water use efficiency of the Golden Pear of T2 were higher than other treatments; the new shoot growth, the fruit daily growth \yield \ water use efficiency of the Golden Pear of T3 were all higher than those of CK and T1; and the yield of the Golden Pear of T1 was reduced by 4.88% compared with the CK, but with the CK, the total water consumption was reduced by 46.92%, the new shoot’s length and the average daily growth of the golden pear of T1 was higher than that of the CK, and the water use efficiency was improved by 40.08%. The effect of drip irrigation belt layout on fruit shape index and quality was not significant.【Conclusion】From the perspective of the benefit of increasing production and saving water, the arrangement of underground double row of drip irrigation belt is the best.
