Detailed Explanation of the Latest Technical Points for Protected Cultivation of Wax Apple
The wax apple is a relatively popular fruit in recent years. There are now many cultivation models for wax apple, among which protected cultivation is quite common. Protected cultivation of wax apple facilitates the daily management of wax apple growing and helps increase the yield and fruit quality of wax apple. So how should we go about growing wax apple? Below, the editor brings you the key points of protected cultivation of wax apple. Let's take a look together!
1. Selection of wax apple seedlings
In protected cultivation, because the height of the greenhouse is limited, the selection of wax apple seedlings is very important. When choosing wax apple seedlings, we should choose air-layered seedlings or grafted seedlings. This type of seedling has relatively less vigorous growth. Even when it reaches the production stage, the tree will not grow too tall, making it more suitable for management in a greenhouse environment. Therefore, it is not advisable to choose seedling trees, as seedling trees not only have a longer time to reach production, which affects cost and benefits, but also have a relatively tall tree form, requiring more investment in the greenhouse.
2. Environmental regulation
During the cultivation of wax apple, temperature is very important. During the day, the greenhouse temperature should be controlled at around 28 degrees, and at night the temperature should be appropriately lowered by around 8 degrees. In winter, the minimum temperature inside the greenhouse should not be lower than 10 degrees, to avoid frost damage to the wax apple. When the temperature is too low, increase the temperature in time to protect against the cold; when the temperature is too high, ventilate in time to cool it down. Then control the humidity inside the greenhouse well, keeping it at around 70%-75%, to prevent excessively low air humidity from reducing the number of flowers and fruits of the wax apple. Finally, the carbon dioxide concentration inside the greenhouse is also quite important. If the concentration is too low, it will affect the photosynthesis of the wax apple. Therefore, pay attention to supplementing carbon dioxide inside the greenhouse.
3. Water management
The roots of the wax apple are not distributed very deep, and it likes to grow in a moist environment, with relatively poor drought resistance. Therefore, during the growth period of the wax apple, pay attention to watering frequently to maintain the soil moisture content and meet the water needs of the wax apple. However, also pay attention to the amount of watering to avoid waterlogging, which affects root respiration and reduces fruit quality. At the same time, also do a good job of intertillage and loosening the soil to improve soil permeability and promote root growth. During the fruit ripening stage, control the amount of watering well; the soil only needs to be slightly moist.
4. Scientific fertilization
The wax apple grows relatively fast, and its annual growth amount is also relatively large. Therefore, its demand for fertilizer is also relatively high, so in addition to applying sufficient base fertilizer each time, we must also do a good job of topdressing. Organic and inorganic fertilizers should be applied in combination, with soil fertilization and foliar fertilization working together, and at the same time pay attention to supplementing trace elements and high-quality organic fertilizer. However, pay attention to the content of harmful gases such as ammonia in the greenhouse, to prevent excessive content from affecting the growth of the wax apple. Also ensure that farmyard manure is fully decomposed, and control the amount of fertilizer applied to avoid excessive fertilization, which can cause fertilizer damage to the crop.
The above is a brief introduction to the key points of protected cultivation of wax apple. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
