Kiwi males and females

Question: Kiwi

I have a pergola with ten kiwi plants, seven females and three males.
Is the proportion right?
I've planted them for four years and so far they've paid me very little. Is it normal?
What recognizes the male from the female?
Do the two sexes have one inflorescence?
Thanks and best regards

Kiwi males and females: Answer: kiwi

Dear Giacomo,
Thank you for contacting us about the KIWI questions via the Expert's column.
The name Kiwi is normally attributed to the plant ACTINIDIA, a plant native to southern China, where it grows as a spontaneous plant, but which has spread considerably in New Zealand. The fruit of this plant was called kiwi, like the bird with thin feathers and the long beak emblem of the southern country.
It requires deep, fresh, well-drained soils, with low active limestone content, environments with frequent lowering of temperature, windy areas and areas subject to early autumn frosts at the time of harvest should be avoided. Actinidia is a dioecious species, with plants that have only female flowers (pistillifere) and other only male flowers (staminifera). The flowers gathered in inflorescences at the axil of the first leaves of the year's bud, are either physiologically female with aborted or physiologically male anthers with a rudimentary ovary. To obtain fruits it is therefore important to plant, as in your case, both female plants and some male plants.
It is a fruit plant that is bred in the ground but could also be cultivated in pots. The fact that they give little fruit may depend on both unfavorable environmental factors and insufficient plant fertilization.
