Detailed Explanation of Key Points for High-Yield Cultivation and Management of Sugar Apple
Sugar apple is the custard apple (sweetsop). Sugar apple has only become popular in China in recent years. Sugar apple is native to the Americas, and it is now grown in tropical regions such as southern China. Sugar apple is not only a fruit with very high nutritional value, but also a Chinese medicinal herb with medicinal value. More and more people are growing sugar apple, so how should it be managed during cultivation to achieve high yield? Below, the editor brings you the key points for high-yield management of sugar apple. Let's take a look!
1. Planting Conditions
Sugar apple is a tropical fruit that likes warmth and moisture. The growing temperature for sugar apple should be controlled at around 22 degrees. And during the cultivation process, it needs a large amount of water, and the air humidity content must not be lower than 70%. To grow high-yield sugar apple, it is necessary to control the growing environment of sugar apple well, so that its growth has sufficient nutrients and water, enhance the growth of sugar apple trees, and increase the fruit-setting rate of sugar apple. Also, drainage and irrigation work in the orchard should be done well, and good windbreak equipment should be established.
2. Reasonable Seedling Raising
Before sowing and raising seedlings, the seeds should be sun-dried and seed-dressed to increase the germination rate, and the seedling bed should preferably be chosen in a sunny and wind-sheltered place. Before planting, the soil should be plowed and sun-exposed, then sufficient base fertilizer should be applied, fully mixed with the soil, and then the furrows and beds should be trimmed. After sowing, cover with fine soil and plastic film in time, compact it, and water promptly. Sugar apple seeds like water but are also afraid of waterlogging, so water control should be noted during the seedling raising process. Prevent excessive water accumulation from causing root rot, and too little from reducing the germination rate. Also, after the seedlings emerge, uncover the plastic film to prevent the seedlings from being pressed.
3. Timely Field Planting
The field planting time for sugar apple is generally around the Beginning of Spring each year, and in tropical regions it can be appropriately advanced. If grown in a greenhouse, it can be delayed until around Qingming Festival. This is because the temperature at this time has gradually risen, which is very beneficial to the growth of sugar apple. Before field planting, the trees should first be trimmed and disinfected, and healthy seedlings with no disease, no pests, and no obvious wounds should be selected as planting seedlings. If nutrients and water are insufficient, before planting, the roots also need to be soaked in water for about 4 hours.
4. Flower and Fruit Management
In order to increase the yield of sugar apple and achieve the goal of high yield, artificial pollination is needed during the flowering period of sugar apple. This is because the success rate of natural pollination of sugar apple is not high, and the fruit set is relatively small. During artificial pollination, a brush or similar object can be used to dip pollen onto the female flowers. When fruiting begins, check the fruits regularly, and if fruits with abnormal shapes, diseased fruits, or thin and weak fruits are found, they should be removed in time. Also, bagging work should be done well to prevent interference from birds and insects, reduce the incidence of disease, and enhance fruit quality.
The above is a brief introduction to the key points for high-yield management of sugar apple. If you want to grow high-yield sugar apple, then you must do all the orchard management work well. It should be noted that sugar apple is very sensitive to temperature changes, so basically no sugar apple trees can be seen in the north. That is all for today's introduction.
