The purpose of reasonable pruning is to improve the ventilation and light conditions in the park through pruning, promote coloration and prevent cracking. When pruning in summer, it is mainly to wipe buds, picking hearts and pruning.
The orchards cover the early stage of fruit growth, covering the plastic film or crop stalks in the tree tray, which is conducive to maintaining soil moisture, preventing garden floor knots and reducing pomegranate cracking.
Rational irrigation of pomegranate irrigation should be based on the principles of small, balanced, multiple and appropriate controls. In production, generally in the rapid growth or expansion period of young fruit, every 10 to 15 days of irrigation water; close to the rainy season, gradually increase the number of irrigation, and every 7 to 10 days to the crown spray water to increase the park's air humidity , Wet skin, enhance the adaptability of peel to continuous rain and high humidity environment to prevent cracking. When the fruit is about to mature, stop watering.
Rational fertilization of the pomegranate tree fertilization should be dominated by organic fertilizer, sufficient phosphorus, potassium fertilizer, as far as possible less nitrogen fertilizer. During fruit enlargement, spraying with 0.3% KH2PO4 solution or 0.5% CaCl2 solution is beneficial to enhance the toughness of the peel and prevent cracking.
Reasonable control in the late development of pomegranate fruit, spraying the fruit surface with 2510-6 gibberellin solution can reduce the cracking fruit by 30%. In addition, at the pomegranate fruit pods, stick tape strips soaked in a 1010-6 to 3010-6 gibberellin solution or spray 0.3% paclobutrazol solution, 2010-6 to 2510-6 ethephon solution, Reduce or prevent the effect of cracking.
The fruit bagging is generally carried out in the young fruit period, and has the functions of preventing disease, preventing insects, and preventing fruit cracking. Bagging has a certain buffer effect on the drastic changes in temperature and humidity, can protect the skin, reduce the drastic changes in daylight temperature and humidity during the dry and dry period, and has a certain buffering effect. It can protect the skin and reduce the sunburn on the skin during drought and dry period. Continuous high humidity damages the toughness of the peel, thus preventing cracking.
