How to make kiwifruit bear fruit

Kiwi fruit requires sufficient sunlight, reasonable pruning, scientific fertilization, artificial pollination, and pest control. Kiwi fruit is a dioecious plant, so it is important to plant it with pollination trees and strengthen growth cycle management.

1. Adequate sunlight

Kiwi fruit is a light loving plant that requires at least 6 hours of direct sunlight per day. When planting, choose sunny slopes or open areas to avoid obstruction by large trees or buildings. insufficient light can lead to excessive growth of branches and leaves, poor flower bud differentiation, and significantly reduce the fruiting rate. During strong summer light, shade nets can be used for moderate protection, but long-term shade should not be used.

2. Reasonable pruning

In winter, it is necessary to cut off diseased and insect infested branches, crossed branches, and overly dense branches, and retain robust fruiting mother branches. Timely heart picking in summer to control vigorous growth and promote lateral branch development. When pruning, pay attention to retaining an appropriate proportion of fruiting and vegetative branches. Generally, the fruiting branches should retain 3-4 full bud points. Excessive pruning can weaken tree vigor, while insufficient pruning can affect ventilation and light transmission.

3. Scientific Fertilization

During the germination stage, nitrogen fertilizer is mainly used to promote branch and leaf growth, and phosphorus and potassium fertilizers are applied before flowering to increase fruit setting rate. Supplement trace elements such as calcium and magnesium during the fruit enlargement period, and apply organic fertilizer to restore tree vigor after fruit harvesting. To avoid excessive application of nitrogen fertilizer during the flowering period leading to flower and fruit drop, the soil pH should be maintained between 5.5-6.5, and lime should be sprinkled for improvement when it is too acidic.

4. Artificial pollination

When the natural pollination rate is low, artificial assistance is needed. Within 2 days after the female flowers bloom, dip the male flower pollen with a brush and lightly coat the female flower stigma, or shake the male plant to scatter the pollen. It is advisable to operate from 9-11am when the humidity is moderate, and avoid watering immediately after pollination. Each female tree should be equipped with 8-10% male plants as pollination trees, and the flowering period of male plants should match that of female plants.

5. Disease and insect pest control

Canker disease can be prevented by spring thunder fungus spray, and root rot disease needs to be controlled by watering and applying Bacillus subtilis. Key pest control measures include controlling the beetle and leaf roller moth, hanging insect traps or spraying Bacillus thuringiensis. Regularly clean the orchard of weeds and fallen leaves, and in winter, paint the tree trunks white to prevent freezing and disease. Avoid using highly toxic pesticides and stop using them 20 days before harvesting. Planting kiwifruit requires keeping the soil loose and breathable, and timely drainage and flood prevention during the rainy season. Build a trellis to guide the growth of vines, remove deformed and small fruits during the fruiting period, and retain 2-3 high-quality fruits per fruiting branch. Different varieties have different requirements for low temperature. Chinese kiwifruit requires 500 hours of low temperature below 7 ℃ for normal flower bud differentiation. Plants that have not yielded fruit for three consecutive years should consider replacing pollination trees or switching to superior varieties.
