不同生育期调亏灌溉对荒漠绿洲区葡萄生长、产量和品质的影响
Effect of Regulated Deficit Irrigation at Different Growth Stages on Growth and Fruit Quality of Wine Grape in Desert Oasis
摘要
Abstract
A favorable water condition in soil for grape to grow is a key factor that impacts growth, fruit quality and final yield of the grape. An experiment was conducted on a 13-years-old vineyard in attempts to investigate the consequence of deficit irrigation at bud break, flowering and fruit setting, fruit enlargement and fruit ripening stage respectively. The minimum soil moisture was controlled at 55%to 60%of the field capacity. Relevant mor-phological, physiological traits and grape yield were measured. The results showed that deficit irrigation only once did nothave significant effect on morphological traits (including plant height, length and diameter of new shoots)and fruit quality (including total sugar content, the amount of soluble solid tannin and total phenol, antho-cyanins content), but affected yield. For example, a deficit irrigation at fruit enlargement stage reduced the yield by 40.2%, while a water deficit at the bud break stage increased the yield by 10.3%.关键词
