Apples are a very common fruit, and the main environmental requirements for apple cultivation are as follows.
1.Soil requirements
Soil has a certain influence on the growth rate, yield and quality of apples.
Apples should be planted in deep, well-drained, loose, fertile and organic soils with a pH of 5-8.
To ensure the quality and taste of apples, do not choose poor, alkaline or poorly permeable clay soils.
2.Lighting requirements
Apples like to grow in a sunny environment.
Only when there is enough light, the photosynthesis of apple trees will lead to strong growth and produce more and better apples in quantity and quality.
To ensure the normal growth of apple trees and improve apple production and quality, we must ensure sufficient sunlight when planting.
3. Precipitation
Water plays an important role in the growth of apples.
Generally, the fruit trees can absorb about 1/3 of the natural precipitation, and during the growth period of apple trees, as long as the precipitation is 540 mm, it can meet their growth needs.
4.Temperature requirements
Apple trees like to grow in a cold and dry environment, they have a strong resistance to cold and heat, the appropriate growth temperature is between 12-25 ℃.
If the planting facility temperature is below 12 ℃ or above 30 ℃, will affect the growth of apple trees.
To ensure that apple trees can dormant properly, it is best to control the temperature below 8°C in winter, and only after the apple trees are dormant will they continue to sprout in spring.
There are also techniques for apple picking, and the fruit should be picked in order.
It is best to pick the fruit at the periphery of the canopy and the upper part of the tree first, and then the lower and inner part of the fruit, branch by branch, to prevent leakage.
When picking the fruit, use the fruit picking platform as much as possible and do not go up the tree to protect the branches, leaves and fruit from being bruised or stepped on.
At the same time, when picking fruit, to pick lightly, lightly unload, to reduce the touch, crushing injuries and other losses, and pay attention to protect the fruit stalk.
Secondly, to pick on a sunny day.
In the case of fog, dew, raindrops, the fruit is easy to rot, not resistant to storage.
So it is best to choose a sunny day to pick the fruit, and the picked fruit will be placed in the ventilation to dry.
Finally, the harvest is done in 2-3 batches.
The first batch is picked from the upper part of the canopy and the outer part of the tree with good coloring and large fruit.
The second batch is best done 5-7 days later, again with good coloring and large fruit.
And the next 5-7 days, all the remaining fruit on the tree is picked, generally speaking, the first two batches of fruit should account for 70%-80% of the whole tree, and the last batch of fruit accounts for 20%-30%.
Usually apples are ripened in late summer and early fall.
Apples do not have a long shelf life, usually only 7-10 days.
They taste best when placed at room temperature and kept for no more than 2 weeks
