apple

Apple, with the scientific name Malus domestica, is a deciduous tree from the rose family.

Soil conditions:
Apple trees are more resistant to humid conditions and little air. The texture of the soil and its permeability to air is directly related to the quality. For this reason, sandy-clay or clay-sandy soils are preferred to heavy clay or very light stony and sandy soils. they give

Planting intervals:
The distance between the seedlings on the rows varies according to the type of base, but it is mandatory to observe a distance of 3 meters between the rows.

Pests:
Root white cream:

White rootworms feed on the roots. Adult larvae attack the trees and cut the roots and the trees suddenly dry up.

Apple wax aphid:

The most damage of the pest is on the top branches, but it winters on the roots near the soil surface and starts its activity from there to some extent.

Lathe Worm:

After hatching, the first instar larvae enter the branches from the junction of the petiole to the branch and thin branches with a diameter of 2 to 4 mm.

long horned cockroach:

Larvae of the wood-eating pest are active inside the branches and young trunks of the host.

apple weevil:

The nymphs on the fruit are mostly male and almost all the nymphs on the leaves are female.

Pea weevil:

Infected branches gradually dry up. The feeding of the insect from the host is accompanied by the secretion of copious sap, in such a way that the lower branches and leaves of the tree are stained, thus causing respiratory disorders.

Apple green aphid:

The pest sucks plant sap with its sucking mouthparts and causes growth to stop or slow down in the branches.

apple high school:

After feeding briefly and changing the skin once, these larvae are released from the parenchyma of the leaf and feed as a group of tissues between the veins of the host leaves.

Apple round spot minnow:

This pest is a small butterfly with light gray wings and half-tip with black and orange patterns. The pest spends the winter in the form of a pupa inside the white cocoons and in different places such as under the bark of the trunk and branches of the host, in the soil layer, and even in the flower area of ​​the apple fruit.

European red tick:

The overwintering eggs are hatched in the spring after the leaves open and before the flowering, and the pest larvae, which have three pairs of legs, come out and start feeding on the leaves from the very beginning. As a result of feeding from plant sap and air penetration, color change occurs in them.

Apple cream:

The key pest and in fact its situation is the focus of apple pest control.

hair chain:

The main damage of this pest is caused by nymphs.

Apple fertilization:
Apple trees use most nutrients, but the most important ones are potassium and calcium.

Phosphorus is added when planting. Potassium is necessary for the size, color and taste of the fruit and it prevents the trees from freezing in the spring. Calcium makes the fruit firm and quality.

Deficiency in apple results in blackening of the middle of the apple, malformation of the fruit, corking of the tissue and skin of the fruit, and cracking of the tree trunk. Potassium causes better absorption of calcium.

When the fruits are ripe, wrap the apples that are small and weak so that the rest of the fruits grow well and fully ripen.

Apples should be kept at a temperature between 0 and 7 degrees Celsius. Apples will stay healthy for up to six months at the mentioned temperature.

Among the fertilizers that are produced in Yadnegar Structures Company (Cinco) and can be used for apples.

Calcium acetate, postafert (Zadekh), potassium sulfate, potassium acetate, liquid calcium are recommended due to the fact that complete NPK fertilizers have micronutrients.
