The price and planting method of peach seedlings

Peach is a small deciduous tree of Rosaceae, which likes light, warmth, cold tolerance, fertile and well-drained soil, alkaline soil and clay soil, not resistant to water and moisture, shallow roots but many fibrous roots, developed roots and short lifespan. It takes about 2 years from planting to fruiting, and 5 ~ 6 years to enter the full fruiting period. let's take a look at the peach seedling price and planting method.

How much is a peach seedling?

The price of peach seedlings is about 2-4 yuan per tree, but the price varies greatly due to different varieties, specifications, producing areas and so on. Peach trees have wide adaptability, can be planted all over the country, easy cultivation and management, and strong adaptability to soil climate. The main varieties are nectarine, flat peach, Shouxing peach, blue peach and so on. Nectarines and flat peaches are cultivated as fruit trees, and longevity peaches and green peaches are mainly for viewing. The more important varieties are Yingshuang red peach, golden autumn red peach, autumn red peach, golden peach, red leaf blue peach, purple leaf plum and so on.

The method of selecting and purchasing peach seedlings

1. Root system: high-quality peach seedlings should have complete, dense and evenly distributed roots. Peach seedlings with serious mechanical damage and few or no lateral roots are inferior seedlings.

2. Plant shape: the plant shape is upright and uncurved, the branch distribution is reasonable, there are 4-5 good branches in the shaping belt, the stem has good elasticity, no damage, the terminal bud is full, and the sturdy seedlings are high-quality peach seedlings, otherwise they are inferior seedlings.

3. Axillary buds: high-quality peach seedlings should be above cadre position, and there should be more than 6 or 8 full axillary buds within the plastic belt.

4. Specification: the height of high-quality peach seedlings should be up to 1 meter, the stem diameter should be measured from 8 cm to 10 cm above the healing mouth of seedling grafting, and 0.7 cm to 1 cm in diameter.

5. Interface: the combination of rootstock and scion of grafted peach seedlings should be completely healed, and the healing degree of split grafted peach seedlings should reach more than 1.5%. If the healing degree of budding seedlings is not good, it is not suitable to choose and buy.

6. Diseases and insect pests: peach seedlings suffering from leaf spots, ulcers, rust spots, hairy root diseases and various quarantine diseases and insect pests should not be selected where the leaves are chlorotic or deformed, such as wrinkling, obesity, etc.

7. Skin color: peach seedlings with fresh skin color should be selected, preferably the seedlings that are now planed from the nursery. The wrinkled skin of the seedlings indicates that they have been dehydrated, and it is difficult for such peach seedlings to survive after planting.

8. Variety: peach seedlings belong to grafted seedlings. Peach seedlings should be purchased as far as possible from the main producing areas of the varieties, because large fruiting trees in large areas can ensure the use of high-quality peach scions and ensure the purity of peach seedlings.

Planting methods of peach seedlings

The main results are as follows: 1. planting method: the row spacing of peach trees is 4 × 5 meters or 3 × 4 meters, and 35-55 trees are planted per mu. The planting period can be from defoliation to pre-sprouting, but not continuous cropping, otherwise the growth of young trees is obviously weak, the leaves lose green, the new roots turn brown and the branches flow glue.

2. Rational fertilization: the requirement ratio of nitrogen, phosphorus and potassium for peach trees is about 1 ∶ 0.5 ∶ 1. Young trees should pay attention to control the application of nitrogen fertilizer, otherwise it is easy to cause overgrowth, and nitrogen fertilizer should be applied after the full fruiting period to enhance the tree strength.

It is better to apply ① base fertilizer in autumn combined with deep ploughing. Early application of base fertilizer can quickly heal roots and increase the accumulation of nutrients in trees before winter. It should be applied as early as possible in spring and immediately after soil freezing.

② topdressing: pre-flowering fertilizer was applied after freezing in spring, mainly urea, post-anthesis fertilizer was mainly phosphorus and potassium fertilizer, fruit fertilizer was mainly diammonium fertilizer, postharvest fertilizer was used to supplement tree consumption, mainly diammonium fertilizer, and a small amount of urea.

3. Tree pruning: peach trees are light-loving fruit trees with weak stem, strong growth potential and short life span, strong sprouting and branching power, and are prone to secondary to tertiary secondary shoots, and the results are poor if they are not pruned improperly, so the happy tree shape without central stem is often used for shaping or pruning.

① young tree stage: peach seedlings should make full use of its strong growth, strong sprouting and branching ability, early mature buds forming multiple auxiliary shoots on strong branches and early flower bud formation. On the one hand, expand the crown, on the other hand, cultivate strong backbone branches.

② full fruit period: peach trees are pruned in the middle and lower part of the tree body or fruiting branch group, leaving 3-5 or 1-2 nodes according to the strength of branches to promote new shoots and form fruiting branches in the next year.

③ growth period: the growing season of peach trees should distinguish the quality and nature of branches according to their growth potential, thickness and position, remove competitive branches, thin and weak branches, dense branches and drooping branches, and remove long branches and over-dense branches sprouting inside the crown.

Disease and pest control of peach seedlings

1. Peach leaf shrink disease

[hazard characteristics] the leaf shrinking disease of peach is mainly harmful to leaves, twigs and young fruits.

[control methods] when the peach buds were swollen but not blooming in spring, ① was sprayed with Baume 5 degree stone sulfur mixture or 1 type Bordeaux solution. After diseased leaves were found by ②, the ascomycetes were removed and burned in time before forming the ascomycetes.

2. Peach scab

[hazard characteristics] peach scab is mainly harmful to fruits, but also to shoots and leaves. During the initial disease of the fruit, dark green round spots appeared on the fruit surface, and then gradually expanded.

[control methods] before germination, ① sprayed Baomei 5 stone sulfur mixture to eradicate or reduce the source of overwintering bacteria on branches, and sprayed Baume 0.2-0.4 stone sulfur mixture every other month from half a month to June. ② in winter combined with pruning, removal of diseased branches, or elimination to reduce the source of overwintering disease.

3. Peach anthracnose

[hazard characteristics] the young fruit showed dark brown, stagnant development, atrophy and sclerosis. When the larger fruit is infected, dark green water stains appear on the initial fruit surface, and the enlarged depression is dark brown.

[control methods] ① in winter combined with pruning to remove diseased branches and fruits and reduce the source of disease. ② was sprayed with Baume 5 °stone sulfur mixture before germination, or 1000 times of organic sulfur preparation or 70% methyl topiramate wettable powder since the fruit was large.

4. Peach tree rot

[hazard characteristics] Peach tree rot mainly harms the trunk and big branches, causing dead trees. When the disease is serious, the whole body is covered with glue, the bark tissue is rotten, the moisture has the smell of wine lees, and then it dries and shrinks, and there are black spots on it.

[control methods] ① cultivates tree potential and strengthens fertilizer and water management. ② scrapes the disease spot in time to the xylem, and then smears it with 40% fumaric arsenic or 50% bacilli. ③ burns the diseased and withered branches sawed every year in time and cannot be stacked near the orchard.

5. Peach gum disease

[harm characteristics] Peach gummy disease is an important disease of branches. In spring and summer, lenticels are the center of the new shoots, and some protuberant disease spots of different sizes produce colorless and translucent soft gum. In serious cases, the bark is cracked, the branches die and the tree is weak.
