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