October apple ripening management needs to be fine

Post-harvest color enhancement

For fruits with poor natural coloring, artificial coloring can be carried out by selecting dry and flat ventilation, laying 3 cm thick sand or grass, placing the fruit tops up, the fruit handles facing down, and the single layer lying flat in the sand. On the surface, during the day, I saw the light at night, and from 9:00 am to 4:00 pm, I covered the fruit surface with a banquet to prevent sunburn. After 4 days and nights, the fruit will reach its proper color.

Post-harvest fertilizer

Immediately after picking the fruit, spray the whole plant with 300-400 times of potassium sulfate type compound fertilizer, or Fuwan potassium 500 times liquid + 0.5% urea liquid, or the original biogas slurry, and spray it once every 8 to 10 days. Delaying leaf senescence, enhancing photosynthesis, increasing storage nutrients, facilitating flower bud differentiation and safe wintering of trees.

Simple storage

The heap will be sorted and distributed in baskets and stacked directly on the ground between the rows of fruit trees. The general storage pile is 1.5 meters wide and 0.6 meters high. After the fruit is piled up, it can be covered with banquets and straw curtains during the daytime to prevent the sun from shining, and the cover is released at night to reduce the temperature of the heap.

Improved trench storage Choose a trench with a width of 1 m and a depth of 1 m in the shade. The length is determined by the storage volume, and a 10 cm thick straw curtain is used as the ditch cover. The ditch is covered tightly during the day before storage, and pre-cooled at night for 10 days. The graded fruit was then placed in a plastic bag, and the mouth was pre-cooled for 2 nights and then tightly packed in the mouth for storage in the morning. During the day, the ditch is covered tightly, and the night is opened and cooled down. The ditch temperature reaches -3 °C, and the ditch should be sealed to keep warm.

Young orchard irrigation water

Before the end of October, the young orchards should be frozen in advance and the amount of water should be sufficient. After water seepage, ploughing and fine hoeing can make the soil freeze late and the frozen soil layer is shallow. The soil is thawed early in the spring of the next year, and the cold and drought are lightly harmful, which is beneficial to prevent the sapling phenomenon.

Control

In order to prevent the young trees from causing dead branches and dead trees due to spawning on their branches, they can be painted on the trunk and main branches of the young trees before the beginning of October to prevent the green leaves from falling. This spawns. The formula of white paint is: 10 parts of quicklime, 1-2 parts of salt, and 35-40 parts of water. The quicklime is turned off with water, the residue is removed, poured into brine, and stirred evenly.
