Foliar spray fertilizer at the initial flowering stage of pomegranate, with 0.5% urea solution, 1% calcium perphosphate leaching solution, 0.3% potassium dihydrogen phosphate solution or 0.3% borax solution foliar spray, can increase the fruit setting rate by 7% to 10%.
After the flowering and thinning of the pomegranate is bud, when the tubular flower and the bell-shaped flower can be distinguished, most of the bell-shaped flower should be removed to reduce the nutrient consumption. After fruit setting, timely remove the small fruit from the diseased fruit, malformed fruit, late flower fruit and bush fruit. The amount of fruit thinning depends on the tree potential. The general result is more and more sparse. When the result is small, it only sparse the disease and fruit, and does not sparse the fruit; the old and weak trees are sparse, and the robust trees are sparse. Practice has proved that the earlier and more thorough the flower buds are eliminated, the more obvious the effect of increasing the yield; the fruit thinning can also make the fruit ripening period consistent, large and good quality.
When the artificially-assisted pollination tree is small and the amount of pollination is small, the tubular flower can be directly pollinated with the bellflower that has just been opened, or the pollen can be collected from the normal flower of the pollination tree, and then the main plant is just planted. The normal flower head is opened for pollination. If the powder is given, the petals can be removed for marking. When the amount of pollination is large, first collect the excess normal and intermediate buds and flowers that will be opened or opened from the pollination tree, remove the petals, take out the anthers, and dry them in a dry, ventilated place with light. The anther is cracked, and then the shell is placed in a desiccator built into the refrigerator for storage. When pollinating, use a brush to smear the flowers
