What to Do About Kiwifruit Fruit Drop? A Detailed Guide to the Latest Control Measures

Kiwifruit, also called kiwi, is a fruit whose taste differs from that of other fruits; it is juicy and sweet, with a unique flavor. It is rich in vitamin C, can stabilize mood, and helps with digestion, among other effects. But kiwifruit often drops its fruit during growth. How can you effectively prevent and control fruit drop? Come take a look with the editor.

1. Scientific pollination

Pollination work must be completed reasonably, and previous incorrect pollination methods must be changed. Growers should try not to store pollen for more than one year, because self-collected pollen has relatively high purity, and pollen cannot be sealed, cannot maintain a dry environment, and its temperature cannot be controlled below -18 degrees. So it is best not to store it; pollen should also not be exposed to the sun above 28 degrees, and tools such as blenders must not be used to extract pollen, because this will further reduce pollen purity.

2. Water management

The moisture in the field must be kept within a suitable range; the water content in the field should be above 65%; pay attention to field humidity, and orchard humidity should be above 55. However, note that pollen must not encounter water; if it does, the pollen's style will rupture, making pollination impossible and defeating the purpose.

3. Dealing with adverse weather

When low temperatures arrive, sprays such as amino acid formulations should be applied to improve the tree's resistance. If it is during the flowering period, irrigation can delay the flowering time of kiwifruit, letting the flowers avoid the low-temperature weather and reducing losses. If the frost season is approaching, artificial smoke should be used to protect the trees from freezing; if it is after flowering, decide based on the pollination situation. If high-temperature weather occurs, irrigate more, but do not irrigate too much water at one time, to prevent flower drop caused by too great a temperature difference.

4. Strengthen management

Increase soil fertility, using about 3000 kg of farmyard manure as base fertilizer, and apply it evenly. Remove weeds from the orchard, and strengthen the orchard's facilities, such as integrated automatic fertilizing and watering equipment. Also prune excessively long branches appropriately, regulate the tree's nutrition and development well, and do not plant too densely; yield per mu is about 1000-2000 kg.

5. Disease control

When selecting seeds, choose disease-resistant seeds, or disinfect the seeds before sowing to improve the disease resistance of the whole plant. When disease characteristics are found, spray promptly, clean up diseased residues, and disinfect the orchard. Around Qingming Festival is the onset period of sclerotinia disease, and chemicals such as vinclozolin can be sprayed for prevention. But do not do this when the temperature is relatively high, to avoid phytotoxicity.

The above are the prevention and control measures for kiwifruit fruit drop. Kiwifruit is a fruit very sensitive to the external environment, so you must pay attention during the flowering and fruiting stages.
