Abstract

The phytomonitoring is a technology that provides information in real time of crop water status and allow to make a feedback between crop and grower to improve the irrigation control. The aim of this investigation was to asses the plant water status and your effect on yield and quality parameter in a commercial vineyard under drip irrigation in an Ultic Palexeralf soil during the 2008-2009 growing season at Central Southern of the Ñuble Region, Itata Valley, Chile. The experimental design was split-plot with three treatments of soil texture: clayey loam, sandy clay and clayey, and three sub-treatments of ‘Cabernet Sauvignon’, ‘Merlot’ and ‘Syrah’ cultivars. Stomatal conductance, leaf-air temperature, cluster weight, berry diameter, berry weight, and soluble solids content were evaluated. The results showed that the phytomonitoring is useful to evaluate the irrigation management in vineyards. Stomatal conductance and leaf-air temperature showed good performance as indicators of vine water status and grapevine quality. This study highlight the effect of soil texture on yield and wine quality in grapevines of semi-arid zones with drip irrigation.

利用植物监测技术评价智利伊塔塔河谷葡萄园(vitis vinifera l.)灌溉调度

植物监测是一种实时提供作物水分状况信息，并在作物和种植者之间进行反馈，以改善灌溉控制的技术。本次调查的目的是评估2008-2009年生长季，在智利伊塔塔谷Ñuble地区中南部Ultic palerifalf土壤上的一个商业葡萄园的植物水分状况及其对产量和质量参数的影响。试验设计采用裂地法，采用粘土壤土、砂质粘土和粘土三种土壤质地处理，以及“赤霞珠”、“梅洛”和“西拉”三种亚处理。对气孔导度、叶空气温度、簇重、浆果直径、浆果重量和可溶性固形物含量进行了评价。结果表明，植物监测对葡萄园灌溉管理的评价是有益的。气孔导度和叶空气温度作为葡萄水分状况和葡萄品质的指标表现良好。研究了半干旱区滴灌条件下土壤质地对葡萄产量和品质的影响。
