Embodiment 1
[0037] Embodiment 1: The impact of spraying calcium on fruit firmness
[0038] In 2006, the late-maturing peach Jingyan from the Huaijia orchard in Xinli Village, Nandulehe Township, Pinggu District was used as the test material, and 15 Jingyan plants with moderate growth and moderate fruiting were selected. On July 4th, July 10th, July 26th, August 1st, August 8th, and August 16th, the concentration of 0, 0.5%, 1%, and 1.5% nitric acid was sprayed on the tree respectively. Calcium solution, contrast is water and sodium nitrate, and the spray dose to every tree is 2.5 liters / tree, and each treatment is repeated 3 times. The fruit harvest date is September 11 (normal production and harvest date). After harvesting, the fruit was stored in a refrigerator at 0°C, and samples were taken on day 0, day 5, and day 10, and the hardness, soluble solids, etc. were measured.
[0039] like figure 1 As shown, the fruit after calcium spraying, on the day of harvest, there is no significan...
Embodiment 2
[0040] Embodiment 2: the impact of different bagging on fruit quality
[0041] In this experiment, Jingyan (11-year-old, rootstock is peach) was used as the test material. The fruit bags used are conventional bags and sulfuric acid paper bags, the conventional bags are basically opaque, and the light transmittance of the sulfuric acid paper bags is about 50%. The sulfuric acid paper bag is homemade, made of sulfuric acid paper for ordinary drawing, and the size is the same as that of a conventional bag.
[0042] The bagging and harvesting periods are consistent with the general production period, and the bagging and harvesting periods of Jingyan are 8 / 4 and 9 / 11 respectively. Jingyan is out of the bag at 9 / 1. (See figure 2 , image 3 )
[0043] like figure 2 , image 3 The hardness of the sulfuric acid paper bags shown is significantly higher than that of conventional bags. There was no significant difference in soluble solids among the treatments.
Embodiment 3
[0044] Embodiment 3: the influence of paving reflective film on the color and luster formation of face fruit
[0045] In this experiment, Huayu (grafted from Pantao Gao last year) was used as the test material. Paper bag specifications are as above, with no bag (CK) as a control. The bagging and harvesting periods are consistent with the general production period, 7 / 13 and 9 / 5 respectively. The bag was removed twice on 8 / 17 and 8 / 29 respectively, and the reflective film was laid at the same time as the bag was removed for the first time. The fruit in the conventional bag without reflective film was used as the control. (See Figure 4 , Figure 5 , Image 6 ) fruit is taken from the ground 1.5 meters (top circumference of the tree crown) and 1.0 meters (the inner cavity of the tree crown).
[0046] like Figure 4 As shown, the anthocyanin synthesis of the back-lit surface of the fruit of each treatment of Huayu variety, no matter it is the fruit on the upper part of the ...
