What is the suitable altitude for planting kiwifruit?

Kiwifruit is suitable for growing at an altitude of 200 ~ 800m, and it is most suitable at an altitude of about 500 m. It is not suitable for growing below 150 m or above1200 m. The altitude of Xiaxia Qiu Ping area and shallow mountainous areas is generally between180-800 m.

Kiwifruit is usually planted in March and April every year, and the prepared saplings are planted according to the plant spacing of 2.0-2.5 meters and the row spacing of 3.5 meters, because the temperature begins to warm up during this time, which is more suitable for the growth of kiwifruit.

Kiwifruit is distributed in China, Shaanxi (South), Hubei, Hunan, Henan, Anhui, Jiangsu, Zhejiang, Jiangxi, Fujian, Guangdong (North) and Guangxi (North). It grows in the forest at an altitude of 200-800 meters, and generally appears in tall grass shrubs, shrubs or sub-unfamiliar forests, and likes soil with rich humus and good drainage; Those who are distributed in the north prefer to be born in a warm and humid environment with lee and sun.

Requirements of kiwifruit on growth environment;

1. temperature: temperature is one of the important factors affecting the growth and development of kiwifruit, which can grow normally in the area with annual average temperature of 1 1℃. The germination of kiwifruit is very sensitive to the requirement of temperature, the average temperature of its germination is relatively stable, and its biological elasticity is 8℃. If the daily average temperature is higher than 8℃, it will germinate and grow, and if the daily average temperature is lower than 8℃, its growth will be affected. Long-term sunshine, high temperature and dry weather in summer will also affect the growth and development of kiwifruit, and there will be defoliation, fruit drop or dead branches.

2. Moisture: Moisture is the most basic component of kiwifruit. Water must participate in all kinds of life activities. Insufficient or excessive water will affect the growth and development of kiwifruit. Kiwifruit has a shallow root system and is not drought-tolerant, so it should be irrigated in time and reasonably during the growing season, high temperature and drought, replenish enough water and reduce the temperature of the tree. Kiwifruit grows well under the conditions of rainfall 1000 mm and air relative humidity of 70%-80%.

3. Soil: Soil is the foundation for the growth and development of kiwifruit, and the nutrients and water it needs are mainly taken from soil. Various physical and chemical properties of soil directly affect its growth and development. Kiwi likes sandy soil with deep soil layer, fertile and loose soil, good water retention and drainage, and high humus content. Therefore, we should pay attention to the selective improvement of soil in the cultivation process. Kiwi also has certain requirements for soil pH, and kiwifruit can grow normally in the range of soil PH5.5-6.5. Iron deficiency and yellowing will occur in alkaline soil with pH above PH7.5, so it is necessary to take timely measures to improve the conditions required for kiwifruit to receive good growth results.

4. Illumination: Kiwi's requirements for illumination vary with age. They like shade at seedling stage and light at adult stage. In good sunshine, the tree grows strong and bears fruit. The sunshine hours that affect the yield and quality of kiwifruit in natural distribution areas are mostly between 300 and 2600 hours, which can generally meet the requirements of its growth and development for light.
