| Choose experimental breading of 6-year-old two optimal variety cultivated by College of Horticulture of Northwest A&F University(plant-spacing is 1m,row-spacing is 3m)and15-year-old Qin peach(plant-spacing is 3m,row-spacing is 5m),design gradient control repeat test,research the processing of fruit quality,yield,and vegetative growth under different fruit load.Moreover,explore the relative suitable for peach through rigorous data comparative analysis,the results showed that:1.Different load of fruit has a significant effect on the single fruit weight of the three species of peach trees.ForⅡ12-49 peach,fruit quantity for it on the 45 of a piece of fruit processing,the average fruit weight is 200.44 g,and significantly better than other treatment;In the case of the Qin peach,the average weight of the fruit was 172.99 g,which was significantly better than the other treatments.ForⅡ12-53,keep fruit quantity for 55 of a piece of fruit processing and other treatment effects on the fruit weight of difference is not obvious,but its fruit is still among the highest in the four processing.2.Different retention of fruit have effect on the soluble sugar content of fruit,acidity and hardness,experimental results show that,in general,for the weight of the largest amount of fruit processing,their hardness and sugar content of fruit are superior to other processing.3.The results showed that the growth of the peach tree was proportional to the yield.4.ForⅡ12-49 andⅡ12-53 peach,fruit load is inversely proportional to the number of the new branch;for the Qin peach,fruit load is inversely proportional to the diameter of the new branch. |
