When the roots of peach trees rot, a toxic substance-amygdalin will be formed, which will be decomposed into highly toxic hydrocyanic acid. It is very harmful to stone fruit trees. If the soil is not improved and peaches, plums, apricots and cherries are planted directly, the trees will die seriously, and the old trees will not be serious, which is often called continuous cropping disease.

Peach Tree: Latin scientific name: Prunus persica, English name: Peach, and species name: Peach. Distribution: It is native to China and widely cultivated all over the world. Small deciduous trees, 4-8 meters high. The leaves are ovate-lanceolate or round-lanceolate, 8- 12cm long and 3-4cm wide, with fine serrations on the edges, no hair on both sides or no sideburns between the axils of the inferior veins; Flowers solitary, the first leaf open, subsessile; Calyx tube campanulate, with short villi, ovate lobed leaves; Petals pink, obovate or oblong-ovoid; The fruit is spherical or ovoid, with a diameter of 5~7 cm, short hair on the surface, white and green, and ripe in late summer; What kind of fruit is pink, fleshy, juicy, fragrant, sweet or slightly sweet and sour? The nucleus is flat and heart-shaped and extremely hard.

Peach trees are small deciduous trees with weak dryness and short curing period of the central trunk, and they are often cultivated in a happy shape. The crown height is 4-5 meters, and the crown diameter is about 6 meters according to the degree of close planting.

Peach trees grow faster and can blossom and bear fruit in the second year after planting. The shoots grow vigorously, and new shoots can be born three times a year, and secondary shoots can also form flower buds, blossom and bear fruit. You can enter the full fruit stage in 4-5 years. Because of the early fruiting, the full fruit period can last 10- 15 years, and the life span of trees is short, mostly in 20-25 years.

The fruiting branches of peach trees are formed by the differentiation of axillary buds on new shoots into flower buds, which are one bud and one flower. The number of fruits is closely related to the quality of fruits and cultivation conditions. Early-maturing and early-maturing peaches cultivated in southern China often affect the improvement of yield and quality because of the high humidity of groundwater and air during the rainy season.

Peach trees like to grow on land with abundant sunshine, loose soil and low groundwater level. It is suitable to choose sandy soil or gravel soil with high dryness for farming, and it can also be cultivated for cohesive soil with low groundwater level, high organic matter content and good drainage.

Peach trees like sunshine. Under natural conditions, centers have no central leadership, but they are still open trees. Therefore, when modeling under cultivation conditions, we should also adopt single-layer trees with low crown and good light reception, such as cup-shaped trees and happy trees. Naturally growing peach trees have dense branches, poor illumination, small fruiting area and low yield. It can be seen from the production that peach trees that are not pruned before 5 years old may have good results because of their small crown, few branches and good ventilation and light transmission. However, after 6 years, the crown gradually increases, the number of branches increases, the ventilation and light transmission are poor, and the output will decrease year by year. However, the yield of peach trees with reasonable pruning and good tree structure is increasing year by year, and the quality is high and stable.

Peach root contains amygdalin, which produces hydrocyanic acid when it decays and decomposes, which can have toxic effects on the roots of young trees, making them grow poorly and even die. Therefore, peach trees should not be cultivated continuously, and new land should be chosen for new peach trees. However, if continuous cropping is needed, leisure farming should be carried out for 2-3 years after the old trees are eliminated, or the method of digging large planting pits to change soil should be adopted to ensure the normal growth of young trees.

In a word, peach trees grow fast, bear fruit early and are easy to cultivate. Trees like sunshine and are resistant to dryness, but avoid humidity and poor drainage conditions. Peach has high yield and early fruit. Therefore, it is very important for peach planting to strengthen cultivation management and improve fertilization level.
