摘要
对‘国光’苹果两种树冠结构、光照特点、光合效率、干物质的生产与分配、果品的产量与品质进行了研究。探明双层形的光照状况明显优于圆头形,其光合强度、光合效率、各器官干物质积累的总量、果实干物质的积累量,平均每公顷产量比圆头形分别高25.45％、12.47％、15.31％、50.69％、19.18％,且果品质优,产量稳定。该研究结果经在河北省大面积推广应用,其增产、增收效果十分显著。
A comparative study was carried out, 1982~1985, on the crown structure, photosynthetic characteristic, photosynthetic efficiency, production and distribution of dry matter, fruit yield and quality of two
chief shapes of crown-two-layer-crown and round-head-crown-by
30-year-old 'Ralls'apple trees in the orchard of Changli Fruit-tree Research Institute, Hebei Academy of Agriculture and Forestry Sciences. The result of this study verified that the illumination phase of two-layer-crown was much preferable to the round-head-crown.Its photosynthetic rate, photosynthetic efficiency, total dry matter accumulation of various organs, dry matter accumulation of fruit and average yield per 0.066ha were 25.45% , 12.47%, 15.31%, 50.69%, 19.18% respectively higher than the round-head-crown. And its fruit was of high grade quality and stable yield.
The result of this study verified its outstanding capability in raising fruit yield and income when extensively introduced to different apple growing districts in Hebei Province.
