What are the key points of spring management for peach trees? Fruit growers, save this for later use
In spring, temperatures warm up and rainfall is abundant, and it is exactly the period of bud break, flowering and fruit setting. Management at this stage affects the later yield and quality, and directly affects the income of fruit growers. So how should peach trees be managed in spring? Let's take a look at the detailed introduction.
1. Topdressing
When March arrives, the temperature rises and stabilizes, and peach trees successively enter the bud break stage, flowering stage and new shoot growth stage, all of which consume large amounts of nutrients. Therefore, in order to meet the nutrients needed for the growth and development of peach trees, topdressing should be done in time. Especially for fruiting trees that grew weakly last year or trees with higher yields, appropriate nitrogen fertilizer can be applied before bud break, which can promote plant growth and development as well as fruit setting. For plants with vigorous growth, it may not be applied, so as to avoid excessive vegetative growth of the fruit trees, which is unfavorable for flowering and fruit setting.
2. Flower thinning and freeze prevention
In spring, the temperature warms up, but in late spring there will still be a late spring cold spell, and a sudden drop in temperature will cause freeze damage to peach trees, which is unfavorable for their flowering and affects the fruit setting rate. Therefore, freeze prevention measures should be taken before and after the flowering period, and sprays can be applied before and after flowering for prevention. In addition, for varieties with a high fruit setting rate, flowers can be thinned from the bud stage to the early full bloom stage, removing overly dense flowers and basal flowers, which can save nutrient consumption, concentrate nutrients, and increase the fruit setting rate.
3. Weeding and loosening the soil
In spring, the temperature rises, and it is also a period when all things revive. Besides peach trees budding and flowering, weeds in the orchard also begin to grow vigorously. They will compete with peach trees for nutrients and also provide shelter and breeding places for pests and diseases. Therefore, weeding and loosening the soil should be done in time. This can not only reduce weeds competing with the trees for nutrients and reduce pests and diseases, but also increase soil permeability, which helps lower ground humidity, increase low temperature, and promote the growth and development of the root system.
4. Pest and disease control ⟧11⟧Spring is also the period when pests and diseases revive. In March, the focus should be on controlling scale insects. If the damage from scale insects was severe last year, the whole orchard can be sprayed with Jiemanling to control this pest. To prevent diseases, the whole orchard can also be sprayed once with lime sulfur mixture. In April, the focus should be on controlling aphids and shot hole disease, especially before and after peach tree bud break. Once aphids are found, spray imidacloprid in time for control. It is also necessary to pay attention to gummosis caused by other diseases. After peach trees finish flowering, diseased leaves can be removed by hand, and overwintering larvae of other pests can be caught and killed.
Spring is also the revival period for pests and diseases. In March, the focus should be on controlling scale insects. If scale insect damage was severe last year, you can spray the entire orchard with jiemanling to control this pest. To prevent diseases, you can also spray the entire orchard once with lime sulfur mixture. In April, the focus should shift to controlling aphids and shot hole disease, especially before and after peach trees bud. Once aphids are found, promptly spray imidacloprid for control. At the same time, also watch out for gummosis caused by other diseases. After the peach blossoms fade, you can manually remove diseased leaves and capture and kill overwintering larvae of other pests.
