The latest course on cultivation techniques and methods of Annona seedlings

Annona, also known as Sakya fruit, Lai cone, Buddha head fruit, etc., is a perennial semi-deciduous small tree belonging to Annona family. It originates in tropical America. Its propagation methods include seed propagation, grafting propagation. Seed propagation seedlings have early-bearing and high-yield characteristics, but their characters are difficult to maintain and premature senescence. Therefore, grafting propagation is often used in production. Let's take a look at the cultivation techniques of Annona seedlings together.

Growth Habits of Annona

Annona like light, more suitable for health in warm and humid climate, the best growth environment average temperature above 22 degrees, not suitable for growth in cold places, suitable for health in fertile sandy soil with good drainage, mainly mature period in June to November, China Hainan, Fujian, Taiwan, Guangdong, Guangxi, Yunnan have cultivation.

Annona seed seedling

Annona seeds should be dried before sowing to promote germination. Nursery should be sunny, well drained, fertile sandy loam, and gentle slope ground is preferred. Nursery before sowing should be first deep tillage drying 1~2 months, and then decomposed organic fertilizer and a small amount of lime as base fertilizer, break and mix well, and then repair the furrow. Sowing and sowing can be done, with 7~8 kg seeds per mu. With river sand or fine soil cover, slightly compacted after watering grass or plastic film, seedbed pay attention to moisture, but also afraid of ponding, so also pay attention to prevent excessive moisture, so as not to cause root rot. After germination, remove the mulch or plastic film to avoid bending the seedlings.

Grafting seedling of Annona squamosa

The grafting methods of Annona apple vary with seasons. The phloem is not easy to be cut off in spring, so the branch grafting method is generally used, while the bud grafting method is generally used in summer and autumn. When grafting Annona by bud grafting method, it is generally required to untie after 20~30 days, while by branch grafting method, it is generally required to pick buds first and then untie them. For the surviving plants grafted by bud grafting method, about 15 days after untying, the rootstock can be cut at about 5 cm above the bud grafting position. After cutting the rootstock, a large number of sprouts will be taken out at the base, which should be removed in time to avoid competing with scions for nutrients and affecting the germination of buds. Meanwhile, the nursery land should be kept clean and free of weeds, and sufficient fertilizer and water supply should be ensured. When the grafted seedlings grow to 50 cm high and the stem thickness is about 1.0 cm, they can be planted out of the nursery.
