Kiwi is native to the south of China. Because macaques like to eat this kind of fruit, they are named kiwifruit. Kiwifruit has been widely planted since it was introduced into New Zealand. People named kiwifruit after kiwifruit, the national bird of New Zealand, and called it "kiwifruit", which is one of the most famous fruits in New Zealand.

Kiwi is a large deciduous woody vine with dioecious plants. Male plants have hairy leaves, and male flowers also appear in female flowers earlier; Female plants have almost no hair, and their leaves and flowers are larger than those of male plants. The flowering period is May-June, and the fruit maturity is 8-65438+1October.

Growing environment:

Temperature is the main factor limiting the distribution, growth and development of kiwifruit. Every species has a suitable temperature range, beyond which it will grow poorly or cannot survive.

Most kiwifruit varieties require warm and humid climate, that is, subtropical or temperate humid and semi-humid climate, which is mainly distributed in the vast area of north latitude 18-34 degrees. The annual average temperature is about11.3-16.9℃, the extreme maximum temperature is 42.6℃, and the extreme minimum temperature is about -20.3℃ and 65438.

Kiwifruit populations have different requirements for temperature. For example, China kiwifruit grows well at the annual average temperature of 4-20℃, while delicious kiwifruit is most widely distributed at 13- 18℃.

The growth and development stages of kiwifruit are also affected by temperature. Studies have shown that when the temperature rises to about 10℃, the tender buds of Actinidia deliciosa begin to germinate, and when the temperature is above 15℃, it can blossom and bear fruit above 20℃. When the temperature drops to about 12℃, they enter the defoliation dormancy period, and the whole development process takes about 2 10-.
