| 摘 要： | 利用pvc管进行保水剂施用深度筛选试验,供试保水剂品种为MP3005KB、US和XM,每个品种4个施用层次,分别为土表下10、20、30和40 cm,以不施保水剂为对照,探讨不同保水剂及施用深度对玉米产量性状及土壤水分利用效率的影响,以确定最佳施用深度。结果表明,保水剂MP3005KB施用深度30~40 cm,保水剂US和XM施用深度20~40 cm,玉米产量和土壤水分利用效率均极显著高于同品种的其他处理和对照。保水剂施用深度30~40 cm效果最佳。

| Abstract: | Using the PVC pipe, the water retaining agent depth screening test for application was done. There were three kinds of water-retaining varieties were used, they were MP3005KB, US and XM. Application four levels for each, They were 10, 20, 30 and 40cm from the soil surface, with no water-retaining agent application as the con- trol. Discussion the effects of the depth of water-retaining agent application on maize yield traits and water use effi- ciency, in order to determine the optimal depth of application. The test results showed that the maize yield and soil WUE were significantly higher than those of the other treatments and control of water-retaining agent MP3005KB was applied in 30-40 cm, and US and XM were in 20-40 cm. So water retaining agent in soil 30-40 cm was the best. |
