Key Technical Points and Precautions for Papaya Flowering Period Management
We are relatively familiar with papaya, which has a wide range of uses. The plant can serve as an ornamental tree species, the fruit can be eaten as a fruit, and the whole plant can be used as medicine. Its nutritional value, medicinal value, and economic value are extremely high. During cultivation, flowering period management of papaya is extremely important. Its flowering period affects its fruit-setting rate and is closely related to yield. So how should papaya be managed during the flowering period? Let's take a look together.
1. Fertilization
In order to ensure that the fruit has enough nutrients to grow, fertilization must be carried out during the flowering period, especially after the flowers fade. When papaya flowers fade, it means the fruit begins to grow, and at this time nutrients must be maintained. At this stage, fertilization can involve topdressing with a nitrogen-phosphorus-potassium compound fertilizer, but fertilization should be moderate and not excessive. If too much fertilizer is applied, it will affect fruit growth. Fertilization is generally calculated according to the size of the plant, applying about 250-500 grams per plant. After fertilization, water can be applied to dissolve the fertilizer and speed up plant absorption.
2. Bee Placement for Pollination
Papaya can set fruit through self-pollination, but in order to increase the fruit-setting rate, cross-pollination must be relied upon. This helps improve the fruit-setting rate, and the fruit quality is also better. Beehives can be placed in the orchard during hot weather so that pollination can rely on bees. Generally, placing 1-2 hives per hectare is sufficient; too many or too few are not suitable. Too many will affect the growers, while too few are not conducive to pollination. The degree must be well controlled, and the number of hives should be increased or decreased according to actual conditions.
3. Artificial Supplementary Pollination
Artificial supplementary pollination can also be carried out. This is mainly aimed specifically at papaya varieties with a relatively low fruit-setting rate. These varieties have a particularly low self-pollination fruit-setting rate and low yield, so artificial supplementary pollination should be carried out. Pollination involves carefully removing papaya pollen without damaging the flower buds, then drying it in the sun for storage. When pollinating, use a brush to dab the pollen onto the stigma of opened flowers. The pollen can also be made into a pollen solution and carefully sprayed with a sprayer, which can also achieve the purpose of pollination. This method is suitable for large-scale planting.
4. Flower Thinning and Fruit Thinning
Flower thinning should be carried out during the stage when the inflorescence extends and the flower buds separate. This time period lasts about one week, which makes the operation convenient. When thinning flowers, excessively numerous, excessively dense, and weak inflorescences can be removed according to spacing, and robust inflorescences should be retained at a certain spacing. This prevents nutrients from being consumed by weak inflorescences, allows more nutrients to be supplied to the growth of robust inflorescences, gives the fruit more nutrients, and makes growth more robust. The same applies at the fruit stage: remove weak fruits that are growing too densely and in excessive numbers. Only in this way can the plant's yield be increased and economic returns be raised.
