| 摘 要： | 以常规滴灌为对照,研究了适时滴灌条件下监测点土壤含水率、葡萄生长过程及产量的特征。结果表明,粘壤土条件下,与40cm和60cm监测点土壤含水率相比,20cm深度监测点土壤含水率具有代表性好、灵敏性高、达到设计土壤含水率下限的时间间隔比较合理的优点,可作为该地区葡萄适时控制灌溉的理想深度;适时滴灌条件下,葡萄的叶面积指数、地上净生物量、叶片生理指标和产量均略低于常规滴灌,但水分利用效率高于常规滴灌。 |

Study on The Timely Controlled Drip Irrigation of Grape in Extremely Arid Regions |
|
| Abstract: | Based on the conventional drip irrigation,field experiments were carried out to study the characteristics of soil moisture at monitoring point,grape growth process and yield under the condition of drip irrigation for timely monitoring.The results showed that:in the clay loam soil,compared with monitoring soil moisture variation characteristics of 40cm and 60cm,the soil moisture monitored of 20cm in depth had the advantages of representative,high sensitivity,and the reasonable time interval reaching the design soil water content.Depth of 20cm was adjudged ideal depth of grape timely control irrigation;Grape leaf area index,net aboveground biomass,leaf physiological index and yield under timely drip irrigation were slightly lower than those under conventional drip irrigation,but water use efficiency was higher than that under conventional drip irrigation. |
| Keywords: | Extreme arid region timely irrigation soil moisture growth yield |
