1 Select the land suitable for planting pomegranate trees. In order to get a good harvest of guava, we should choose the soil layer suitable for planting guava. Pomegranate trees like the planting ground with rich soil layer, loose soil layer, good air permeability, convenient irrigation and shelter from wind and rain. Pomegranate is one of the fruits of tropical rain forest, but it prefers warmth. Transplanting after defoliation in autumn in southern areas and higher survival rate before germination in spring in northern areas.
Pay attention to watering pomegranate trees, which are subtropical evergreen plants. The seedlings like water very much. The transplanted seedlings are watered more and more times, which has a significant effect on promoting survival. Generally, the newly planted guava seedlings are covered with soil to the tree transplanting line, and the watering pit is emptied. Water them as soon as they are stable. Water each plant about 15kg. A layer of 65438+ can be covered on it after water infiltration.
You don't have to smooth the water, the interval is about 7 days. It is always necessary to keep the roots of newly planted pomegranate trees moist by watering them again and again. This makes it very easy to survive. Although pomegranate has a thick rhizome, it is not easy to survive if it is not carefully watered. If possible, drugs such as long-rooted seedling promoter and rooting agent can be added to the planting water to improve the survival rate. In order to better enhance moisture retention and hydration, plastic films can be covered around the roots of seedlings.
Three methods to improve the survival rate of pomegranate trees transplanted in summer. Pomegranate trees can be transplanted all year round, and the temperature is relatively high in summer, and it volatilizes quickly. At this time, it is necessary to water more, raise the sunshade properly, spray water on the trees, reduce some environmental temperatures and reduce the evaporation of leaves, which has a great effect on improving the survival rate.
4 Fixed drying In order to improve the survival rate, pomegranate trees should be fixed before transplanting. The relative height of fixed stem of one-year-old seedlings is about 65 cm, and that of two-year-old seedlings is 75 cm, which does not have to exceed 80 cm. If the pomegranate tree is large, the long branches are beneficial to transplantation, and the resulting wound can be wiped with the original solution of thiophanate-methyl suspension, and then tied. At the same time, all the buds inside the main pole are removed, which improves the ventilation transparency after work.
5 Fertilization Under normal circumstances, the newly planted seedlings are not fertilized to prevent the seedlings from burning out and difficult to take root. Two weeks after planting, a fertilization pit with a depth of 40 cm square was dug next to the planting pit, and about 10 kg of fully decomposed high-quality farmyard manure and 250 g of 50% NPK controlled release fertilizer were applied to each pomegranate tree. Immediately after fertilization, it can be watered with permeable water, which can be mixed with amino acid water-soluble fertilizer.
Some friends try to save trouble. When transplanting pomegranate seedlings, organic fertilizer should be applied at the same time If the selected organic fertilizer is not well decomposed, it is easy to burn seedlings. Even if it is to be applied together with the planted seedlings, the fertilization distance should be appropriately extended.
