求各位高手帮我翻译一下这一段英文,谢谢(翻译要专业点哦)!!!

Introduction

Drip irrigation in processing tomato is a common technique in Portugal due to the Mediterranean climate, with dry and warm summers and high evapotranspiration rates throughout the growing season. These are conditions that make subsurface drip irrigation a suitable alternative to the surface system.With subsurface drip irrigation, evaporation from the topsoil is reduced and water runoff is negligible (Phene, 1991; Phene et al., 1992). In addition, with surface drip irrigation, roots grow preferentially around the emitter area (Oli- veira et al., 1996), which in turn can contribute to improve water availability to the plants when using subsurface drip irrigation. The purpose of the present
study was to compare surface vs subsurface drip irrigation (at two different depths) on the root distribution of two processing tomato cultivars. Knowledge of rooting patterns is essential to irrigation and fertilizer management and consequently to tomato yield and quality. Besides using minirhizotrons for root system analysis, trenches were opened perpendicularly to the plant row to examine the root distribution along the soil profile.

滴灌在加工番茄是一种常见的技术,由于地中海气候的葡萄牙,在整个生长季节干燥和温暖的夏季高温蒸发水份。这些条件,使地下滴灌一个合适的替代品对表面加水,蒸发表土和减少水的流失是可以忽略不计 。此外,用地表滴灌,根系生长在地表领域 ,而这反过来又可以有助于改善自来水工厂在使用地下滴灌。本研究是比较表面滴灌与地下滴灌(在两个不同的深度)对根系分布不同的两个番茄品种影响。生根模式是因为不可少的灌溉和施肥管理,因此,番茄产量和品质。除了利用根系分析,壕沟被打开的植物垂直连续根系分布在土壤剖面。
