Careful management during apple maturity
Color enhancement after harvest
For fruits with poor natural coloration, they can be artificially enhanced. Method: Choose a dry, flat and ventilated place, spread 3 cm thick fine sand or grass, put the top of the fruit up and the stalk down, and lay a single layer flat on the sand surface. It will be exposed to light during the day and dew at night. From 9 am to 4 pm, cover the fruit surface with a reed mat to prevent sunburn. Generally, after 4 days and nights, the fruit can reach the desired color.
Spray fertilizer after harvest
Immediately after picking the fruit, spray 300-400 times solution of potassium sulfate type compound fertilizer, or 500 times solution of rich potassium + 0.5% urea solution, or original biogas solution on the whole tree in the afternoon. Spray once more every 8 to 10 days to delay leaf senescence, enhance photosynthesis, increase stored nutrients, and help flower bud differentiation and the tree to survive the winter safely.
Easy storage
Pile up. The selected and graded fruits are scattered or packed in baskets and stacked directly on the ground between the rows of fruit trees. Generally, the storage pile is 1.5 meters wide and 0.6 meters high. After the fruits are stacked, they can be covered with reed mats and straw curtains during the early day to prevent the sun from drying, and the cover should be removed at night to reduce the stack temperature.
Improved trench storage. Choose to dig a trench with a width and depth of 1 meter in the shade. The length is determined by the storage capacity, and a 10 cm thick straw curtain is used as the trench cover. Before storage, the ditch shall be tightly covered during the day, and open and pre-cooled at night for 10 consecutive days. Then put the graded fruits into plastic bags, open the mouth and pre-cool for 2 nights, then tie the bag mouth tightly into the ditch in the morning for storage. Cover the trench tightly during the day and open it to cool down at night. The trench temperature reaches minus 3 degrees Celsius, and the trench must be sealed for heat preservation.
Frozen water for young orchard
Before late October, irrigate young orchards with frozen water in advance, and the amount of water should be sufficient. Plowing and plowing after water seepage can make the soil freeze late and the frozen soil layer is shallow. The soil will thaw early in the spring of the following year, and the cold and drought will be less harmful, which will help prevent the phenomenon of saplings.
Prevention and Control of Green Leafhopper
In order to avoid the occurrence of dead branches and dead trees due to the large green leafhopper laying eggs on its branches, the trunk and main branches of the young tree can be painted white before early October to prevent the large green leafhopper from being This spawns. The formula of the white coating agent is: 10 parts quicklime, 1-2 parts salt, 35-40 parts water, dissolve the quicklime with water, remove the slag, pour it into the salt water, stir well and serve.
