Abstract:
Five-year-old scorpion Corylus heterophylla×C.avellana under of Yellow River Irrigation District in Yongning,Ningxia was used as the research objectives,aiming at studying its growth hand photosynthetic characteristics under control (unpruned),light shear,medium shear,and heavy shear.With the study of the variation of growth and photosynthetic characteristics of Corylus heterophylla×C.avellana under different pruning methods,it was of great significance to explore the rational pruning of high quality Corylus heterophylla×C.avellana. The results showed that,1) with the increase of pruning degree,the horizontal,vertical diameter,crown width,plant height and fruit number of Corylus heterophylla×C.avellana increased first,then decreased and finally increased.Under the various pruning treatments,there had insignificant differences between the horizontal and vertical diameters,and between the number of crowns and inflorescences of Corylus heterophylla×C.avellana (P>0.05).From the aspect of plant height,the plant height of the middle shear was lower than those of the other 3 treatments,and there was significant difference between the control and the light shear treatment.2) The net photosynthetic rate and transpiration rate of Corylus heterophylla×C.avellana increased,decreased,and increased with the degree of pruning.The net photosynthetic rate of the middle shear was the lowest one,and there was a significant difference between the other treatments.The intercellular CO2 concentration of the Corylus heterophylla×C.avellana decreased with the increase of the pruning degree;stomatal conductance of light and reshear was significantly different from that of control and medium shear.3) According to the average membership function value,the pruning method was evaluated and found to be the most suitable pruning method for light-cutting.
