Life knowledge series, introduction to the related knowledge of green plants and flowers about what to do if an apple tree has cracking fruit, next the website editor will introduce to netizens.
What to do if an apple tree has cracking fruit
An apple tree may have cracking fruit due to high sugar content, excessive growth, sudden environmental changes, or wound growth cessation. When an apple tree has cracking fruit, supplementing it with calcium and reducing nitrogen content can reduce cracking to some extent. When selecting varieties, breed crack-resistant ones, strengthen soil management, apply organic fertilizers, water appropriately, and take good drainage measures, and spray urea properly.
Reasons for cracking fruit in apple trees
1. High sugar content: High sugar content in apple fruit can cause cracking because the higher the sugar content, the greater the osmotic pressure inside the fruit, which absorbs a large amount of water and causes the inner flesh to expand rapidly, leading to cracking.
2. Excessive growth: The degree of development of the tree's growth, branch age, and the development of the fruit's stalk depression are related to cracking. When an apple tree grows very vigorously, it is prone to cracking.
3. Sudden environmental changes: If the fruit is grown in dry soil, the growth rate of the fruit skin is slow. However, if it encounters a large amount of rain or irrigation, the soil moisture will increase, and the fruit will continue to absorb water, causing the fruit skin to expand and crack.
4. Wound growth cessation: Apples can have mechanical injuries or pest damage during growth, which can cause cracking.
Methods for dealing with cracking fruit in apple trees
When an apple tree has cracking fruit, supplement calcium and reduce nitrogen. When nitrogen content is high, it affects the absorption of calcium in apple trees, easily leading to cracking. Therefore, supplementing calcium in apple trees can reduce the cracking to some extent.
Preventing cracking fruit in apple trees
1. The most important is to breed crack-resistant varieties, as thicker fruit skin is less likely to crack, and planting in the right season is necessary.
2. Improve soil: Choose sandy loam soil, strengthen soil management, apply organic fertilizers, water appropriately, and take good drainage measures.
3. Spray urea: Spray 500-600 times the concentration of green fresh power mixed with 0.3% urea solution on young fruit after half a month of full bloom, and spray once a week.
