| 中文摘要: |
| 根系分区灌水是一种新型的灌水技术,可以在不影响产量的前提下提高水分利用率。从根系分区灌水概念的提出、生理基础及其在果树上的应用现状等方面对这一技术进行了综述,并分析了根系分区灌水在果树上的应用前景、存在问题及进一步研究方向。 |
| 英文摘要: |
| Partial Rootzone Irrigation (PRI) is a novel irrigaing technique which improves water use efficiency when the production does not decrease. The technique requires that about half of the root system is always maintained in a dry or drying condition while the other half of the root system is irrigated. The wetted and dried parts of the root system are alternated after a period of time. The produce and physiological basis of PRI are discussed in this article. The future and problems of PRI in fruit trees culture are also analyzed. |
