What environment does apple cultivation require? A detailed explanation of the latest environmental requirements
China's apple production accounts for 65% of the world's total output, making it a major producer and exporter, and apples have a cultivation history of more than two thousand years in China. The influence of the external environment on apple growth and development is intricate, so what environmental requirements does apple growth need? Below, Qinnong Network brings you the environmental requirements for apple cultivation. Let's take a look together.
1. Soil requirements
Soil has an enormous influence 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, poor, and poorly permeable clay soils.
2. Temperature requirements
Apple is a common temperate fruit tree that prefers a cool and dry environment and has a certain resistance to cold and heat. The optimal 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 needs to be below minus 8 degrees for normal dormancy.
3. Light requirements
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 precipitation of 800mm is needed to meet their needs. Fortunately, the natural precipitation in most current apple-growing areas in China can meet their needs. However, in areas with more precipitation, attention should be paid to drainage measures. Too much precipitation makes the soil prone to waterlogging, which affects plant growth and, in severe cases, can cause root rot and death. In areas with less precipitation, 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.
