What are the environmental requirements for apple cultivation? A full analysis of suitable conditions
China's apple production accounts for 65% of the world's total output, making it a major producer and exporter, and apples have been cultivated in China for more than two thousand years. The influence of the external environment on apple growth and development is complex, so what environmental requirements does apple growth need? Below, Qinnong.com brings you the environmental requirements for apple cultivation. Let's take a look together.
1. Soil requirements
Soil has a great impact on the growth, yield and quality of apples. Apples are suitable for growing in soil with a deep soil layer, loose and fertile texture, good drainage and rich organic matter. Apples have a certain tolerance to acid and alkali, so a soil pH between 5 and 8 is most suitable. Avoid highly acidic or alkaline, barren, and poorly permeable clay soil.
2. Temperature requirements
The apple is a common temperate fruit tree. It prefers a cool and dry environment and has a certain resistance to cold and heat. The suitable growth temperature is 12-24 degrees. If the temperature is below minus 12 degrees or above 30 degrees, it is not conducive to its growth and development. In winter, the temperature should not be too high, so as not to affect its dormancy and cause it to fail to sprout normally in spring. It must be below minus 8 degrees for normal dormancy.
3. Light requirements
The apple is a light-loving tree species. Only under conditions of sufficient light can it grow and develop normally. With sufficient light, the plant's photosynthesis increases, the plant grows robustly, and the yield and quality of the fruit are high. With insufficient light, the plant will show a series of problems such as excessive vegetative growth, weak branches and leaves, poor disease resistance, low fruit set rate, poor root growth, low sugar content in the fruit, and poor coloring.
4. Water requirements
The growth and development of apples cannot be separated from water. Under general soil conditions, annual rainfall of 800mm is needed to meet their needs. Fortunately, the natural rainfall in most of China's current growing areas can meet their needs. However, in areas with more rainfall, attention should be paid to drainage measures. Too much rainfall makes the soil prone to waterlogging, which affects plant growth and, in severe cases, can cause root rot and death. In areas with less rainfall, attention should be paid to watering to supplement the water supply. Especially in summer when temperatures are high, the plant's transpiration is great, and severe water shortage may cause the plant to wither and die.
