Kiwifruit originated in China and was introduced to New Zealand from Yichang in 1904. After cultivation, it is widely planted in New Zealand. At first, New Zealanders called it Yichang gooseberry. Because of its left-leaning name, it received a cold reception in the market, and later it was renamed melon. However, New Zealand has a higher tax on melon, which was eventually renamed as kiwifruit.
Therefore, kiwifruit is a kiwifruit variety after artificial breeding, with uniform fur distribution and smooth feel; However, its ancestor, Actinidia chinensis, has uneven villi distribution and rough touch.
Kiwi, also known as kiwi fruit, is generally oval, with a yellowish brown appearance in the early stage and a reddish brown appearance after maturity. The epidermis is covered with dense fluff, which contains bright green pulp and a row of black or red seeds. Because macaques like to eat, they are named kiwifruit; It is said that its name is because its skin is covered with hair and looks like a macaque.
growing environment
1, moisture: Actinidia chinensis grows vigorously with large and thick leaves, so it requires strict moisture and air humidity. Chinese kiwifruit is not tolerant to waterlogging, and long-term waterlogging will lead to wilting and death. The air relative humidity is required to be 70%-80%, and the annual rainfall is about1000 mm.
2. Temperature: According to the investigation, Actinidia chinensis can grow in areas with annual average temperature 10℃ or above. In areas with normal growth and development, the average annual temperature is 15- 18.5℃. The average maximum temperature in July is 30-34℃, the average minimum temperature in June is 4.5-5℃, and the frost-free period is 2 10-290 days.
3. Soil: Chinese kiwifruit likes humus with deep, fertile and loose soil layer and alluvial soil. The most taboo is the soil with heavy viscosity, easy waterlogging and poor soil, and the requirements for soil pH are not strict. It grows well in acidic and slightly acidic soils (pH 5.5-6.5) and poorly in neutral alkaline soils.
4. Illumination: Kiwifruit in China likes light, but is afraid of exposure. The requirements for lighting conditions vary with the age of trees. Although adult trees like humidity, they have to climb tall trunks to receive sunlight.
