Study On The Cultivation And Relationship Between The Cultivation And Photosynthesis In Leaves Of Trellis Trained 'Whangkeumbae'

Many Fruit Quality and Photosynthesis in Leaves of Trellis and spindle trained'Whangkeumbae'were studied, such as key cultivation on trellis trained'whangkumbae'and relationship between the cultivation and photosynthesis in leaves of trellis trained'Whangkeumbae',to provide guidance for cultivation of Trellis trained'Whangkeumbae'. Some significant results have obtained as the followings:1. The leakage rate of electrolyte of'Whangkeumbae'shoot had significant variation when the temperature range was -25℃～-30℃.2. Trellis trained'Whangkeumbae'made by cement column need lower cost than which made by steel tube.3.Orchard establishment of trellis trained'Whangkeumbae'should planting pollinate tree,such as Atago,Housui, Nijisseiki and Danbae pear,and so on.4.The tree shape of'Whangkeumbae'and inherent characteristic of photosynthesis in Leaves of'Whangkeumbae'had not significant difference. The photosynthetic ability of leaves on long branch was higher than short branch's. The photosynthetic ability of leaves on short branch which had fruits was higher than which had no fruits. The distribution of light intensity in the canopy of trellis trained'whangkumbae'had consistency from inner to outer layer, the solar energy use efficiency of trellis trained'whangkumbae'was stronger than that on spindle trained'Whangkeumbae'. Long branch:middle branch:short branch were 1:0.5:9 in trellis trained'whangkumbae', and that in spindle trained'Whangkeumbae'were 1:0.4:6. The weight of single fruit of trellis trained'whangkumbae'was consistent, and its percent rate of high quality fruit was higher than that of spindle trained'Whangkeumbae'because of higher solar energy use efficiency.5. The best amounts of main branch were 3 on pruning of trellis trained'whangkumbae'. There were some effects on photosynthesis in Leaves of'Whangkeumbae'after winter pruning. The water sprout above trellis after summer pruning had positive influence on fruit quality, so a certain amount of the water sprout above trellis should been retained when having summer pruning. There was a negative correlation between the annual growth increment of new shoots on the main branch and branch angle,and there was a positive correlation between photosynthetic capacity and branch angle. The competitive branch had inhibitory effect on new shoots on the main branch, and there was a positive correlation between photosynthe-tic capacity and the competitive branch.6. The best fruits interval was 15cm, and the suitable branch-fruit ratio was 3:1 or 4:1, studied by different fruit load. We could draw a conclusion that the fruit bagging had significant good effects on the exterior quality, the double paper bag was not good in fruit management of trellis trained'whangkumbae', and the single paper bag made in Shandong pomology institute was the best by studying different paper bag. The fruit bagging had significant effects on photosynthetic capacity in leaves of short shoot which had fruits.
