Autumn and winter are the seasons for apple harvest. However, in picking apples, it is necessary to have some experience. Because the fruits on the same fruit tree will not mature at the same time, how to manage and harvest apples during maturity?
First, timely bag removal: In addition to the bag too early, the fruit surface is easy to become rough, the color is not fresh, the rate of rotten fruit is high; except the bag is too late, the coloration is poor. Generally, the bag is removed 15-20 days before the harvest. If it is a single-layer bag, the bag is first torn from the middle, but it is still protected from light to prevent the fruit from being burned. The bag is removed after one week. Double-layer bags go to the outer bag first, and then remove the inner bag 5-7 days. Linyi Fertilizer Network Copyright
Second, picking leaves and turning fruits: picking leaves should be carried out after removing the bags, removing the shading leaves and fruiting leaves within 5-15cm around the fruit in stages, so that more than 60% of the fruit surface is exposed to direct light, and the total number of leaves can not be removed. More than 30% of the total leaf volume; when the fruit is sun-colored, it is necessary to manually transfer the fruit to make the shaded fruit surface light. The fruit close to the branch can be rotated 180 degrees and then placed on the branch. After the fruit transfer, the coloring index can be increased by about 20%. Linyi Fertilizer Network Copyright
Third, spraying foliar fertilizer: 30 times before and 30 days before harvesting, each time spraying 2000 times of reddening agent and 0.3% potassium dihydrogen phosphate. The rate of full red fruits increased by 26%. Linyi Fertilizer Network Copyright
4. Reflective film: After the bag, a silver reflective film can be laid inwardly under the tree toward the outer edge of the canopy. Each side of the tree is covered with a stone, and the edge of the reflective film is compacted with stones, so that the lower part of the canopy can be The fruit is especially colored in the fruit and around it. The reflective film is recycled and cleaned before harvesting, and used the following year. Linyi Fertilizer Network Copyright

The smart glass has efficient openness and privacy, can be used in prison visit rooms, tion rooms, isolation rooms etc.
The bulletproof dimming glass partition for bank counter, can easily switch from transparent state for service time and the atomization state for oof time. Especially in normal temperature and humid environments, this situation is more likely to occur. Therefore, when selecting energizing power, it is necessary to comprehensively consider the requirements of light transmittance and service life to achieve a balanced state.
