Potted pomegranates can be a combination of flower viewing, fruit viewing and viewing, and has high edible value and ornamental value. Potted pomegranate due to the convenience of movement, can be used to beautify the courtyard, balcony, roof and layout of the village environment, etc., is a walking orchard, for the urban and rural greening and beautification to add a new choice of content, deeply loved and cultivated by the masses. According to its growth habits, pomegranates and fruits are from spring to late autumn, up to half a year, of which the flowering period is continuous from spring to early summer, and the flowers are gorgeous, up to 2 to 3 months. Whether the management is in place during this period directly affects the development of pomegranate fruit and the ornamental effect in the later stage.
Control the ambient temperature to ensure flowering and fruit setting
Pomegranate flowering period is relatively long, can be divided into three batches of buds, the first batch of flowers is also called the first generation of flowers, it with the germination of leaf buds buds, this first batch of buds although not much, but if the fruit set is successful, the fruit is large and bright color, ornamental is very high. Summer and autumn flowers are mostly unisexual flowers, most of which have degenerated, so they rarely bear fruit.
The habit of pomegranate growth is warm and cold, the most suitable growth temperature is between 15 and 25 ° C, and the light must be sufficient to make the flower buds more differentiated and the fruit develops well. However, the northern part of the continent has lower temperatures in the early spring, and there are often cold air currents, which will make the new branches of the pomegranate grow slowly and the photosynthesis will be insufficient. As a result, the first buds were stunted, and the females and stamens failed to mature in time for pollination, so that the fruit set rate was not high. The solution is to try to raise the temperature of the environment in which the pomegranate grows, placing the potted pomegranate in a place where the sun shines, or it can be placed in a simple plastic shed and filled with fluorescent lamps to meet the temperature and light required for fruit setting.
Pest control protects the flower buds and ensures increased fruit set
Pomegranates are prone to aphid damage from germination to flowering, and if the control is not timely, it is difficult to bear fruit. When pomegranates bloom, the flower buds are extremely allergic to drugs, and if the spray kills insects, the female and stamens stigmas will be damaged, and they cannot pollinate and grow fruit. Based on practical experience, we can spray garlic water, pepper water and tobacco water to kill aphids and protect flower buds.
Timely flower thinning to ensure strong flower results
Although the pomegranate flowers are like brocade, the amount of flowers is very large, but the fruit setting rate is very low, generally less than ten percent, the others are unisexual flowers, only the stamens have no pistils, so they can not grow fruit, they must be cut off in time to concentrate on the supply of nutrients to the full fruit flowers, so that the fruit blossoms develop robustly and improve the fruit set rate.
Scientific watering to protect the growth of fruits
Pomegranate in the flowering and fruit setting period, the response to changes in the growth environment is very sensitive, especially after pollination of young fruits, the soil moisture requirements are very high, must not be dry and wet imbalance, resulting in mutations in the reproductive environment, so it is easy to cause a large number of fruit fall. Therefore, it is necessary to often observe the wet and dry situation of the potting soil, water appropriately, and always maintain the standard of non-dry and non-wet. Proper water control should be done before the fruit ripens, which is conducive to the good development of the fruit. If you encounter continuous rainy weather outdoors, you should take rain avoidance measures to prevent fruit splitting, affecting the ornamental and edible value.
Fertilize reasonably to prevent young fruits from falling fruit
After pomegranate pollination, the young fruit grows to the size of a ping-pong ball, and is allergic to the fertilizer reaction, so it should not be fertilized, otherwise the young fruit will easily fall off. When the fruit grows to more than the size of the ping-pong ball, the fruit is basically stable at this time, and it can be fertilized, generally using organic fertilizer plus inorganic fertilizer for topdressing. For example, 3% calcium superphosphate, 0.5% potassium dihydrogen phosphate, 0.3% urea and the like are sprayed.
