The change of the apple tree in spring, summer, autumn and winter, the process of the apple tree fro

Apple tree. The branches grow tender green leaves and white flowers in the spring, in the summer, they produce small greenish fruits with luxuriant leaves, in the autumn the leaves turn yellow-green and the fruits are red, and finally in the winter, the leaves dry up and yellow, and gradually fall, in addition, the apple tree is very adaptable to the environment and can resist frost of minus 40.

The branches of the apple tree grow tender green leaves and white flowers in the spring, and in the summer, they produce small greenish fruits with lush leaves, and in the autumn the leaves turn yellow-green and the fruits are red, and finally in the winter, the leaves dry and yellow, and gradually fall.

Apple trees are trees.

The plant, the twigs are stout, cylindrical, the leaves are oval, ovate, long and wide, the edges are round and obtuse, the flowers grow intensively at the tips of the branches, the fruits are oblate and spherical, and the fruiting period is from July to October every year.

Apple trees are highly adaptable to the environment, can resist frost of minus 40, and grow best between 35-50 degrees north and south latitudes.

Suitable for growing in hillside terraces, vast plains, etc., apple trees are native to Europe and central Asia, and have a long history of cultivation in the temperate zones of the world.

It is planted in various regions, and it is mainly planted in Shandong, Liaoning, Shanxi, Sichuan, Yunnan and other places.

Spring is coming, the flowers are basking in the sun, and the branches of the apple trees here will grow tender green leaves and white flowers in the spring.

<> apple trees produce new leaves in the spring, bloom from April to June, and by the end of summer, the flowers of the apple trees are almost all shed, bearing unripe fruits. Apple trees are temperate fruit trees that like low temperature and dryness, the suitable temperature range is the annual average temperature of 9-14, the extreme low temperature in winter is not less than minus 12, the average monthly temperature in summer is not higher than 20, and the annual accumulated temperature is greater than or equal to 10 about 5000.

Apple trees will lose their leaves every year, but will not fall in winter, generally apple trees in the autumn of each year a large number of leaves, winter needs to do a good job of cold measures, can be in the autumn after the leaves, to the trunk of the smear layer of lime water, but also to cut off its useless branches, and apply organic fertilizer can help apple trees overwinter, spring germination of new leaves. Imperial Jane.

Apple trees are planted in most of the key sedan areas in our country, it belongs to deciduous fruit trees, the leaves will fall off during a certain period, but it will not fall leaves in winter, and every time it replaces, it needs to do a good job of keeping warm to avoid the plant being frostbitten by low temperature, resulting in its spring can not germinate new leaves.

Apple trees shed a lot of leaves every year, most of the plants are in the winter low temperature to drop leaves, so the apple tree leaves in winter, it generally falls off in autumn, and there are no leaves on the trunk in winter, so it will not continue to fall leaves, but you need to take measures to protect against the cold.

Generally, whenever the apple tree loses its leaves in autumn, then the trunk of the apple tree can be smeared with a layer of lime water, so that the apple tree can be frostbitten in the evening in winter, and the apple tree can be continuously differentiated with the help of sunlight during the day, and its branches can be continuously differentiated and sprout new shoots in spring.

In fact, whenever the apple tree loses its leaves, then you can also give it proper pruning, cut off its excessively long branches, cut off all the useless branches such as dead and weak branches, and then apply organic fertilizer to the potting soil, which can concentrate its nutrients and help the apple tree survive the winter.

Apples are very adaptable to the environment, and its fruit ripening period is also very long, generally in spring, summer and autumn when the fruit is ripe, in fact, early ripening apples in 3 June, medium ripe apples in 7 August, late ripening apples in 9 October, usually when planting apples, must give it enough light, and need to water and fertilize it, but it will reduce the yield of its fruits.

Apple is a relatively common fruit, it contains rich nutrients, apple is very adaptable to the growth environment, and its fruit period is also particularly strong, generally in spring, summer and autumn when the fruit is ripe, these three seasons have fresh ripe fruit sales.

The fruiting period of apples is divided into early, middle and late, it has many different varieties, and the fruit ripening period of each variety is different, and what season is the ripening of apples, early ripening apples in March and June, medium-ripening apples in July and August, late-ripening apples in September and October, and the ripening period is different in different regions.

Normally, apples are mainly ripe in autumn, whenever the apple fruit is ripe, the apple must be placed in the sun for maintenance, but also to give it timely watering, fertilizer careful maintenance, so as to increase the yield of the fruit, but also to increase the nutritional value of the fruit.

In fact, in the process of apple breeding, whenever its fruiting period is over, it is necessary to prune its branches, deal with the diseased part of the plant in time, and cut off the branches that grow too long, so as to reduce the consumption of nutrients and promote the continued fruiting in the next year.

1.Check for lesions and scaling. On the basis of the annual proportions, catch the autumn scrape.

New lesions are removed quickly in the summer, and the ulcers are completely scraped in the fall. Scrape the phloem lesion so deep into the xylem. The wound is fusiform, with smooth edges, blowing green and yellow.

Scraping the bark should be burned intensively. and apply a fungicide. Such as:

2 30 times that of sodium humate; 30 times of arsenic; Arsenic horizontal solution (formay: pin plus : water = 3:

2:100), arsenic-rich solution (fume arsenic:kerosene:

water = 3:1:100), or 70 methyl tobuzin WP30 times, etc.

In order to prevent long-term exposure and dry lesions scraped off the part, paint or coal tar bitumen can be protected with tung oil paint.

2.Fertilizer timely autumn fruit trees to replenish the tree due to nutrient consumption of the tree's fruits. Maintain good vitality. Thus, improving resistance to decay.

3.Improve on-site garbage cleanup, remove diseased branches in time, and reduce the source of initial infection of pathogens.

4.Prune the diseased branches in time and winter pruning. Paint protects large wounds in a timely manner. Reduces the likelihood of bacterial invasion.

5.In early spring, the tree (before budding) is sprayed with stone sulfur mixture at 5 degrees, sprayed on the main trunk, dried, at the base of the main branch. Focus on the affected area.

6.The rot is orchard, heavy frying is carried out in June and July, scraped until more severe, with a green and yellow shape. Scrape the bark clean. 10 days of applicator protection.

7.Master the morphological differentiation of rapid growth, fruit expansion period, flower bud differentiation, trimming work, organic fertilizer, flower thinning, sparseness, reasonable production burden, and improve tree body resistance.

8.For larger lesions, late-spring budding apple varieties can be framed with annual branches to improve the tree's nutrient transport pathways and thus rejuvenate.

All in all, the organic combination of rot prevention and fall, cultivation measures and plant measures can control apple rot disease.

The apple tree loses its leaves in winter because it is a deciduous plant, and when the weather gradually cools, the leaves will gradually turn yellow and fall off, which is a normal phenomenon. The apple tree is a deciduous tree that loses a lot of leaves in autumn and turns bare in winter, so it is not an evergreen plant.

In addition to the natural metabolism, pests and diseases, poor light, drought and high temperatures, and sudden heavy rain may cause apple trees to lose their leaves.

The apple tree is a deciduous tree that loses a lot of leaves in autumn and turns bare in winter, so it is not an evergreen plant.

Apple trees shed their leaves in winter.

Apple trees lose their leaves in winter on their branchesBecause it is a deciduous plant, when the weather gradually cools, the leaves will gradually turn yellow and fall, which is a normal phenomenon of spring.

Causes of apple tree leaf loss.

The loss of leaves in apple trees is most likely due to the infestation of red spiders, which absorb the sap of fruit leaves and fruits, and then affect the formation of photosynthesis of plants, causing early leaf fall.

How apple trees survive the winter.

1. Tree wrapping

For the planted apple saplings, the straw can be tied to the trunk and branches before freezing, which can effectively prevent the invasion of cold snaps and allow the trees to survive the winter safely.

2. Soil cultivation to prevent cold

The apple tree can be cultivated to prevent cold, which can reduce the evaporation of water from the roots of the tree, can increase the soil temperature, the height of the soil can be about 15-20 cm, and it can be removed when it thaws in the second year.
