吐鲁番地区无核白葡萄三种主栽方式的叶幕微气候研究

通过对吐鲁番地区无核白葡萄3种主栽方式的叶幕微气候分析研究,结果表明:单离架叶幕对光能截流水平较高,利于产量形成,但影响品质;小棚架由于较郁闭,叶呆温度较低,一定程度上有利于拮抗吐鲁番地区的高温胁迫,改进品质;大棚架是最差的一种栽培方式.提出了改良3种栽培方式的原则和具体方法.

STUDIES OF THREE PRINCIPAL CULTIVATED SYSTEMS OF THOMPSON SEEDLESS ON CANOPY MICROCLIMATE IN TULUFAN AREA

The experiment carried out with three principal cultivated systems of Thompson Seedless grapevine in Tulufan area:Compared simple hedge-shape(H) with little percola trellis(p),and big percola trellis(bP),shows that the H system has a higher level of leaf radiation(PAR) capture, leaf temperature and berry temperature.It is therefore considered that the H system possesses a better yield of the production of grapes.The P system shows a lower level of berry temperature and leaf transpiration activities than those of the H system,but it possesses a better quality of grapes.The bP system has a lower level of leaf transpiration activities than those of H system.The ways of improvement of these three training systems have been discussed.
