Requirements of apple planting environment

The output of apple in China accounts for 65% of the world's total output, and it is a big country in production and export. Apple has been cultivated in China for more than 2000 years. The impact of the external environment on the growth and development of apples is complex, so what environmental requirements are needed for apple growth? The following pro-agricultural network brings apple planting environment requirements, let's learn about it.

1. Soil requirements

Soil has a great influence on the growth, yield and quality of apple. Apple is suitable to grow in the soil with deep soil layer, loose and fertile soil, good drainage and rich in organic matter. Apple has a certain acid and alkali tolerance, so the soil pH value between 5-8 is the most suitable, avoid acidity and alkalinity, barren, poor permeability of clayey soil.

2. Temperature requirement

Apple is a common temperate fruit tree, like low temperature and dry environment, have a certain cold and heat resistance, the suitable temperature for growth is 12-24 degrees, if the temperature below 12 degrees below zero, higher than 30 degrees are not conducive to its growth and development. Winter temperature should not be too high, so as not to affect its dormancy, resulting in spring can not sprout normally, to be in a temperature below minus 8 degrees in order to dormancy normally.

3. Lighting requirements

Apple is a light-loving tree species, only under the condition of sufficient light, can normal growth and development, sufficient light, increased plant photosynthesis, strong plant growth, high yield and quality. When the light is insufficient, there will be a series of problems, such as overgrowth, weak branches and leaves, poor disease resistance, low fruit setting rate, poor root growth, low sugar content, poor coloring and so on.

4. Moisture requirement

The growth and development of apple is inseparable from water. Under general soil conditions, annual precipitation to 800mm is needed to meet its demand. Fortunately, the natural precipitation in most planting areas of our country can meet its demand. However, in areas with more precipitation, attention should be paid to drainage measures, too much precipitation is easy to accumulate water in the soil, which affects plant growth, and in serious cases, it can rot roots and die; while in areas with less precipitation, attention should be paid to watering to supplement water supply, especially in high temperature in summer. the transpiration of the plant is large, if the lack of water is serious, it may lead to plant death.

The above pro-agricultural network brought about the apple planting environment requirements, apple planting requirements are introduced here, hope to help you, more agricultural knowledge, please pay attention to the pro-agricultural network.
