Raspberry is "seeing white flowers and green leaves in spring, tasting red fruits in summer, enjoying purple leaves in autumn, and watching branches like fire in winter". Potted raspberries can not only beautify the environment, increase fun, but also get ideal delicious products. Black raspberry fruit is purple-black when it matures, with an average single fruit weight of 6.5 to 8.6 grams. After raspberries are potted, they begin to bear fruit in the second year. A pot can bear 0.2-0.3 kg in the initial stage and 0.3-0.5 kg in the third year. If the specifications of pots and barrels are large and properly managed, the output can be increased.

1 flowerpot selection: it is best to choose flowerpots, pottery pots, wooden barrels, etc. of 35-40 cm. , but there should be a leak hole at the bottom.

2 Potted soil preparation: Potted raspberries are limited by containers, so soil with rich and loose soil, good water and fertilizer conservation performance and good ventilation performance should be selected, and natural humus soil is ideal. The artificial preparation method is: 3 parts of rotten leaves, 2 parts of decomposed manure and 5 parts of garden soil, or horse manure, sandy soil and garden soil each 1 part.

3. Sowing: Seedlings can be planted in pots before germination in early spring or after defoliation in late autumn. The roots of dehydrated seedlings can be soaked in clear water for 8- 12 hours, and then rooted in a proper position in the pot to make the roots elongate, filled with soil, compacted and watered by hands, and placed in a humid and warm place.

4. Shaping and pruning: After the seedlings enter the pot, they can be leveled at a height of 3-5 cm. When the new branch grows to 20 cm, the top of the branch can be removed (enucleated) to promote the germination of new lateral branches. When the lateral branches grow to 20 cm, they can be cored repeatedly until autumn, and they can blossom and bear fruit in the next year.

5 watering: the temperature is low in spring, so watering should not be too much. It is best to do it once every 2-3 days. High temperature and high transpiration in summer can increase watering times. At noon, the raspberry basin and the ground are sprayed with water to cool down. Reduce watering times in autumn. It is advisable to water thoroughly without exudation every time.

Fertilization: The nutrition of potted raspberries is supplemented by topdressing. Fertilizer can be fermented with water and combined with watering. It is wise to apply less fertilizer and more fertilizer.

7 pest control: raspberries have strong disease resistance, and pests should be controlled in time.

8 Overwintering management: overwintering dormancy, potted raspberries, raspberries begin to hibernate after defoliation in June165438+1October, and the ideal place is outdoor vegetable cellar. If there is no vegetable cellar, it can be placed in cold places such as corridors and basements. The temperature must be controlled at 5℃-5℃. If the temperature is too high, it will germinate in advance, and if it is too low, it will freeze the raspberries. Regularly check the humidity, that is, control the watering, but also maintain a certain humidity of the basin soil, so as to avoid neglecting watering and dying of thirst when sleeping. In addition, potted raspberries have another feature. If the winter management conditions are good and the temperature and humidity reach the growth conditions of raspberries, raspberries will not shed leaves and continue to grow. If the management conditions are poor in winter, potted raspberries will fall leaves and sleep. Pay attention to the inspection, don't hurt the branches, and move out the next spring when it freezes.
