How to grow Red Delicious apples? Mastering these key technical points is crucial
The Red Delicious apple originated in the United States, and it actually has nothing to do with snakes; it only got the name "snake fruit" because of its transliterated name. Its appearance is similar to that of an apple, and people who do not know it often mistake it for an apple. Its nutritional value is extremely high and its benefits are powerful, making it very popular among consumers on the market. Let's take a look below at the key technical points for growing it, brought to you by Qinong Net.
1. When to plant
Red Delicious apples are generally planted around March in spring. Usually, if planted in the current year, they can bear fruit the following year, and by the third year they can achieve a high yield. The best planting time is before summer. Summer temperatures are high, and saplings planted then generally do not survive easily. The same is true in winter; low temperatures also make survival difficult. After planting, remember to take antifreeze measures in the winter of that same year to prevent the saplings from suffering freeze damage.
2. High-density planting
Generally, fruit trees should be planted sparsely, maintaining spacing between plants and rows, or using a method of dense trees and sparse branches, pruning their branches and leaves during planting to increase air circulation between plants. But Red Delicious apples are different; they can be planted at high density, and this is also beneficial for increasing yield. To ensure high and quality yield, generally in the first two years after planting, tree growth is promoted so that individuals develop well. By the third year, it is a transition period: inhibit individual growth, control the population, and cause the tree to shift from long branches to short branches, and from growing wood to bearing fruit.
3. Fertilizer and water management
Before planting, dig holes and apply 7-8 kg of farmyard manure per hole. After planting, water thoroughly, cover with soil and mulch to keep warm and retain moisture. In the second year, continue to apply compound fertilizer, combining it with watering to encourage more branches and more long branches. As the plant gradually grows, the amount of fertilizer should also gradually increase. When fertilizing, organic fertilizer and compound fertilizer are generally applied in autumn, while nitrogen fertilizer can be broadcast with watering. To avoid loss of fertility, the amount applied each time should not be too much. A sufficient supply of fertilizer and water makes the tree grow extremely fast and bear more fruit, creating good conditions for high and quality yield.
4. Pest and disease control
Pest and disease control mainly emphasizes prevention, and it must be done early. The main diseases of Red Delicious apples include alternaria leaf spot, anthracnose, and ring rot. These diseases mainly harm leaves and the flowering period. About one week after flowering, spraying 50% mancozeb can control these diseases. The main pests are red spiders and aphids. Also when flowering, spraying 000-3000 times dilution of mite killer can provide control for 2-3 months. In addition, when the rainy season arrives, basic copper sulfate and insecticides can be sprayed for comprehensive pest and disease control.
