结果高度、留芽量及叶幕厚度对“厂”形赤霞珠果际微环境和果实品质的影响
Effect of Different Fruit Set Heights, Shoot Densities and Canopy Thicknesses on Microenvironment and Berry Quality of “厂” Shape Cabernet Sauvignon
摘要
Abstract
[Objective] In this article,the effects of fruit set height,shoot density and canopy thickness on microenvironment around berry and fruit quality of Cabernet Sauvignon with ‘厂’hape training structure were studied by L9 (3') orthogonal test design in the hope of providing a theoretical basis for choosing canopy man-agement standards for wine grape in the northern piedmont producing area of Tianshan mountains.[Method] 5a old Cabernet Sauvignon was taken as the testing materials,L9 (34) orthogonal test design was used,3 factors such as fruit set height(A),shoot density (B)and canopy thickness (C) were set and each factor had 3 levels (A:30 cm,50 cm,80 cm;B:25,20,15 bud/m;C:100 cm,80 cm,60 cm),altogether 9 treatments.The temperature,humidity and spectral composition around berry were investigated during the berry veraison,the weight of berry,number of seed,pericarp weight/berry weight,seed weight / berry weight,soluble solid,titratable acid and tannin were measured during the mature period.[Result] Fruit set height,shoot density and canopy thickness influenced the fruit quality through the changing temperature,humidity and spectral composition around berry.Among them,the fruit set height was the main influence factor on spectral composition around berry,soluble solid and titratable acid.The content of soluble solids and titration acid were the highest when the height was set at 50 cm.The content of tannin and fruit was mainly affected by the shoot density,so 25 bud/m shoot density produced the highest value.Canopy thickness was the main influence factor on the number of seed and seed weight/berry weight,so when the thicknes was 80 cm,more number of grains would be fouind.[Conclusion] The order of the influence on berry quality from high to low is fruit set height,canopy thickness and shoot density,among which,the fruit set height 50 cm,canopy thickness 80 cm and shoot density 25 shoot/m have produced the best berry quality.关键词
