苏翠1号梨在不同栽培模式下光能利用及果实品质的比较

Comparison of Light Energy Utilization and Fruit Quality of Sucui 1 Pear under Different Cultivation Modes

以苏翠1号为试材,对其在3种栽培模式(棚架栽培、避雨栽培、露地栽培)下的光能利用率和果实品质进行了比较研究。结果表明:从叶幕光环境来看,树冠外围的相对光照高于内膛;在树冠内膛,在相对光照>30%的高光照区域,棚架最高,露地次之,避雨模式最差,分别为73.28%、69.01%、62.24%;相对强度日变化可知,棚架模式>露地模式>避雨模式;在棚架模式下的单果重、可溶性糖、可溶性固形物均高于其他栽培模式,避雨模式和露地模式下的果实品质差异不显著。因此,从苏翠1号在果园的光环境和果实品质综合考虑,棚架模式优于其他。

The effects of three types of cultivation model(Shelf mode,rain-shelter cultivation,open-field mode)on light energy utilization and fruit quality of early-maturing pear variety Sucui 1 were compared.The results showed that the relative light intensity outside the crown was higher than that within crowns;In the canopy chamber and the high illumination area with relative illumination>30%,the shelf was the highest,followed by the open field,and the rain shelter mode was the worst.They were 73.28%,69.01% and 62.24%respectively.Diurnal variation of relative intensity showed that shelf pattern>open pattern>rain shelter pattern.The single fruit weight,soluble sugar and soluble solids under the shelf mode were higher than other cultivation modes.There was insignificant difference between rain shelter pattern and open pattern.Therefore,the light environment and fruit quality of Sucui 1 in the orchard under the shelf mode were better than those under others.
