How to manage sugar apple for high yield? Latest key points explained

Sugar apple is the custard apple (Annona squamosa). Sugar apple is a fruit that has only become popular in China in recent years. Sugar apple is native to the Americas and is now grown in tropical regions such as southern China. Sugar apple is not only a fruit with very high nutritional value, it is also a traditional 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. Growing conditions

Sugar apple is a tropical fruit that likes warmth and moisture, and its growing temperature should be kept at around 22 degrees. It also needs a large amount of water during cultivation, and the air humidity must not be lower than 70%. To grow high-yielding sugar apple, you need to control its growing environment well, so that it has sufficient nutrients and water for growth, enhance the growth of the sugar apple tree, and increase the fruit-setting rate. You should also do a good job of drainage and irrigation in the orchard and set up good windbreaks.

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 be chosen in a sunny, wind-sheltered place as much as possible. Before planting, plow and sun-expose the soil, then apply sufficient base fertilizer, mix it thoroughly with the soil, and then trim and make furrows. After sowing, cover promptly with fine soil and plastic film, press it down, and water promptly. Sugar apple seeds like water but are also afraid of waterlogging, so moisture must be controlled during seedling raising. Prevent excessive waterlogging from causing root rot, and too little from lowering the germination rate. Also, after the seedlings emerge, uncover the plastic film to prevent the seedlings from being pressed.

3. Timely planting

Sugar apple is generally planted around the Beginning of Spring each year, and in tropical regions it can be done appropriately earlier. If grown in a greenhouse, it can be delayed until around Qingming Festival. This is because the temperature has gradually risen by then, which is very favorable for the growth of sugar apple. Before planting, the trees should first be trimmed and disinfected, and strong, healthy seedlings with no disease, no pests, and no obvious wounds should be selected as planting stock. If nutrients and water are insufficient, the roots also need to be soaked in water for about 4 hours before planting.

4. Flower and fruit management

To increase the yield of sugar apple and achieve the goal of high yield, artificial pollination is needed during the flowering period. This is because the success rate of natural pollination in sugar apple is not high, and the amount of fruit set is relatively small. During artificial pollination, you can use a writing brush or similar item to dip pollen onto the female flowers. When fruiting begins, check the fruit regularly, and promptly remove any fruit that is abnormally shaped, diseased, or thin and weak. Also, do a good job of bagging 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-yielding sugar apple, then you must do a good job in all orchard management tasks. Note 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. This article is for reference only.
