Features of the roots of the apple tree, characteristics of the roots, stems, leaves, fruits, seeds

Apple is a deciduous tree, up to 15 meters high, the trunk is grayish-brown, the old bark has irregular longitudinal lobes or flaky peeling, and the twigs are densely hairy when young, and then become smooth and purple-brown.

The fruit is slightly flattened spherical, with a diameter of more than 5 cm, concave at both ends, and often ridged at the end. The flowering period is 4 June, and the fruiting period is 7 November.

The buds of apples are divided into two types: leaf buds and flower buds according to their nature. The leaf buds are triangular, long and curved at the point, and grow into branches after the leaves are spread, called new shoots or vegetative branches. According to the growth status, the branches can be divided into: long branches, ordinary branches, slender branches, and leaf cluster branches: the flower buds of apples are mixed buds.

The root system of the apple tree is developed, it is a straight root plant, its taproot is more obvious, the root system is generally distributed in the tillage layer of about 80cm, if it grows well, it can be rooted deeper. Planting apple trees can choose a round mouth tile pot, the diameter is about 40-60cm, the depth is according to the height of the root system of the plant, it is best to have drainage holes, such pots have good air permeability and drainage ability, which is conducive to the development of the root system of the plant.

The root system of the apple tree is well developed, it belongs to the deep-rooted fruit tree, generally when the age of the tree reaches 5 years, the root distribution pattern of the plant will be established, and after 6-8 years of cultivation, its root density and biomass will reach the maximum.

How deep the roots of apple trees are in general.

The apple tree is a straight-rooted plant, its taproot is more obvious, its root system is generally mainly distributed in the tillage layer of about 80cm, if it grows well, it can take deeper roots.

Apple trees are suitable for growing pots.

The pot for planting apple trees can choose a round tile pot, with a diameter of about 40-60cm, and the depth depends on the height of the root system of the plant, preferably with drainage holes, such a pot has good enough ventilation and drainage capacity, which is very conducive to the development of the root system of the plant.

Treatment method for underdeveloped root system of apple tree.

If the root system of the apple tree is not developed, phosphorus and calcium can be supplemented in time, which can promote the growth of hairy roots and fibrous roots, and the growth of strong taproots. In addition, when fertilizing, it is necessary to choose one that is easy to absorb and absorb, has a high utilization rate, is not easy to be fixed by the soil, and does not react with phosphorus and calcium, which is conducive to the root growth of the plant.

Apple is a very common fruit tree in the north, and it is also the largest fruit industry in China, mainly in Shaanxi, Shandong, Gansu, Henan, Shanxi, Liaoning, Xinjiang and other places! It has formed ten major production areas and excellent regional brands such as Yantai apples, Luochuan apples, Jingning apples, Qingyang apples, etc.! Its management level leads the country with Shandong Yantai!

But the roots of the fruit trees are rising, which is still worth noting! Here are a few things to keep in mind!

First, the roots of fruit trees are rising, first of all, we should pay attention to whether the tree body is diseased Li Feng insect pests, because the root nutrients can not be transported to the treetops and branches and leaves normally, resulting in excess nutrients in the heels, so they will sprout. At this time, the pests and diseases should be found in time, the disease should be removed, and if the wound is too large, one or two branches should be left and bridged in the upper part of the wound to relieve the nutritional needs of the upper part.

Second, if there are no pests and diseases in the tree, it means that the pruning is too heavy in winter, resulting in the upper part can not consume nutrients normally, and the roots of the tree depth and the hail chain will be rising, at this time, the branches of the roots should be removed in time, and the upper branches should be twisted, pulled, and circumferentially cut, etc., so as to strengthen the summer management, so that the new ones can bear fruit as soon as possible, and the winter management will reduce the amount of pruning and ease the tree momentum. It is important not to remove all the new strips, causing the fruit trees to hurt their roots, or to sprout again in the next year.

Third, if you exclude the above two, you should think about whether the tree body is too heavy, some fruit farmers use the way of ring cutting the tree body to increase the amount of flowers and yield in the coming year, resulting in root nutrients can not be transported to the branches normally, so as to achieve the purpose of easing the tree and increasing the amount of flowers! In this way, the heel will also rise, so you can leave it alone, let it grow, and remove it when the fruit tree is managed in winter. Of course, it is best not to circumferentially cut the tree, because this will promote the aging of the fruit tree, reduce the ability of the fruit tree to resist diseases and pests, and make the strong tree become a weak tree!

The correct way is to circumferentially cut on the fruiting branch group to increase the amount of flowers, and after two years of fruit, the branch source disturbs the grandchild group and weakens, so you can go back or cut off the new branch group!

Fourth, there are dwarf seedlings will also have roots and branches, mainly because the dwarf seedlings have developed roots, but there are grafts that inhibit growth at the grafts, and this graft inhibits the nutrient transport of roots for a long time, resulting in weak fruit trees and the purpose of dwarf fruit trees, so when the roots are overnutrient, they will sprout, and then they can be disposed of in time!

The above four points, I hope to solve everyone's confusion, there are problems in Apple management, you can pay attention to private messages, communicate with each other! Thank you for your support!

The characteristics of the apple tree are: tall tree shape, oval leaves, umbrella inflorescences, spherical fruits, color, etc.

1. The tree shape is tall.

Many people who grow apple trees should want to know what are the characteristics of apple trees. In fact, apple trees are deciduous trees, usually about 15 meters in height, but most cultivated trees are generally only about 3-5 meters tall, the bark is gray-brown, and the fruit is red when ripe.

2. The blade is elliptical.

The leaves of the apple tree are mainly oval in shape. The length is in centimeters, and the width is around centimeters. The edges of the leaves will be more rounded and blunt, and in their infancy, they will have shorter pubescence on both sides, while its leaves will have a grass-like texture, lanceolate, and dense pubescence.

3. Umbrella room inflorescence.

The inflorescence of the apple tree is an umbrella inflorescence, each cluster of small flowers is composed of about 3-7 flowers, generally only grows at the tip of the branch, the peduncle length is about centimeters, its sepals are triangular-lanceolate, about 6-8 mm long, the petals are obovate, between 15-18 mm in length.

4. Spherical fruits.

The fruit of the apple tree is generally oblate spherical, the diameter can reach more than 2 cm, and the front end of the fruit will look slightly raised, and the jaw depression is sunken, with a relatively thick and short fruit stalk, in July and October every year, it will bear fruit, and the flowering period is around May every year.

5. Color. The old branches of the apple tree are purple-brown, the leaves are green, the flowers are mostly white, and the fruit contains a red halo in the early morning.
