How do peony pomegranate spend the winter?

Anti-cold and anti-freezing measures of peony pomegranate tree

Pomegranate, a treasure with many fruits and a rare tree in the world, is regarded as a good omen of prosperity, prosperity, harmony, unity and auspiciousness, and it is a symbol of having many children and grandchildren and a long life. Pomegranate trees flourish, and the flowering and fruiting period is as long as four or five months. In early spring, the new leaves are red and tender; Summer is full of flowers; Mid-Autumn Festival, fruitful; In deep winter, iron is dry. ? Peony pomegranate tree, a treasure in pomegranate family, has considerable flowers, fruits and shapes. Can be used to make bonsai, cultivate trees and flowers, both greening and beautifying. It can be placed in halls, courtyards, squares and streets. Peony pomegranate flowers are big and gorgeous, with many flowers. In 7-8 years, the number of peony pomegranate trees can reach 2-3 thousand, the flower diameter is 8- 12 cm, and the maximum is 15 cm. The flowering period can last from May to 10, with four colors of red, yellow, white and pink, which is very ornamental, green and beautiful.

Peony pomegranate trees are warm, very easy to cultivate, and have no strict requirements on soil, so they can be planted in both north and south. However, attention should be paid to freezing and cold prevention when planting in the north, and the lower limit of low temperature is-17 degrees. Peony and pomegranate seedlings are frozen at-12 degrees, or extremely cold weather and sudden low temperature will also be hurt. On June 65438+1October 19, 2008 (September 2 1 of the lunar calendar), heavy snow suddenly fell in the north, and 1-2-year-old seedlings were frozen to death, and seedlings over three years old were slightly frozen. On October 20 15438+065438+23 (lunar calendar1October 12), heavy snow suddenly fell in the north, and the temperature was low for four consecutive days (minus 9 degrees to minus 13 degrees), and the seedlings were severely frozen in 1-4 years. 2065438+2006 65438+1October 22-24, three consecutive days of extremely cold weather (above-10 degrees), which made the situation of peony pomegranate seedlings worse and caused great losses to seedling farmers. Based on years of research, Heze Peony and Pomegranate Research Institute has summarized the following measures for preventing cold and freezing of peony and pomegranate trees:

1. Reasonable water control. Pay attention to drainage in rainy years, make the branches fully developed, control watering in the later period of growth, and water once before freezing.

2. Scientific fertilization. Abide by the principle of "promoting first, then controlling", apply less nitrogen fertilizer, more phosphorus and potassium fertilizer in the late growth stage, and spray foliar fertilizers such as rare earth and potassium dihydrogen phosphate on the leaves to ensure that the trees are strong and full and improve their frost resistance.

3. Spray protection. Spray antifreeze twice before winter (before and after falling leaves) to improve the cold resistance of peony pomegranate tree itself.

4. Paint the trunk white. Before the cold current comes, combine Qingyuan to paint the trunk white, which is both antifreeze and insecticidal. Now all whitening agents sold in the market can be sprayed with a sprayer, and a tree seedling can be sprayed in 10 second. This method is suitable for pomegranate orchards planted in large areas.

5. The smoke is getting hot. At 8-9 o'clock in the evening when the cold current comes, use smoke such as wheat straw, corn straw (to be crushed) and sawdust to raise the temperature to prevent freezing. Generally, 3-4 fires per mu can raise the temperature by 3-4℃. Be careful not to light it. If the material is too dry, it can be properly sprayed with water, preferably smoked.

6. Plastic wrap. Small trees susceptible to freezing can be wrapped in plastic film. Wrap the grass first, then the plastic film. This method is suitable for pomegranate orchards planted in small areas.

7. Root neck soil. Before the soil is frozen, the root neck is cultivated in combination with intertillage with a thickness of 20 ~ 40 cm. Choose the right time and pick it before the spring buds.

8. Clear the amount of snow on the tree: shake off the snow on the tree in time after it snows and cultivate it at the root of the tree to increase the moisture in the soil and play a role in heat preservation.

9. Build shelter forest: Use shelter forest to improve the microclimate of pomegranate orchard, reduce wind speed, restrain drought and reduce freezing injury.

The above nine measures can be used or implemented selectively. In short, before and after the pomegranate leaves fall, we should pay close attention to the weather forecast, do a good job in cold and antifreeze, and avoid freezing damage to pomegranate trees.
