| 摘 要： | 摘要：本文研究了垄作沟灌条件下，不同生育时期内金盏花土壤水分变化及其产量。试验结果发现：与平作4200 m3/hm2相比，垄作沟灌3600 m3/hm2在各生育期各个土层中保持了较高的水分 ，水分利用效率高41.15%，可增产25% 。结果表明金盏花垄作沟灌合理的灌水量为3600m3/hm2。

| Abstract: | The article studied the changes in soil moisture in every growth developmental stage, the production and pigment content of marigol hybrids under the condition of bed planting and furrow irrigation. It were expected to obtain that best irrigation quota of bed planting furrow irrigation, effects of yield increase and water saving and it ＇ s mechanism. The experiment presented that the bed planting and furrow irrigation with irrigation of 3600 m 3 /hm 2 held the high moisture content during the different growth stage in each soil layer, and raised water use efficiency 41.15% and increase production 25% comparied of flat planting with irrigation of 4200 m 3 / hm 2 . The results indicated： the reasonable irrigation water quantity of bed planting and furrow irrigation in marigold was 3 600 m 3 /hm 2 , and it has obviously effects of yield increase and water saving. |
