Announcement Apple Seed Solution

Announcement Apple trees are planted directly from male trees. The origin of the seeds is very important. The seeds should come from improved varieties (general Annona apples) with good harvests and high-quality mother plants. And for fruits with a straight shape, it is best to use the same kind of fruits that are artificially pollinated. When the fruit is fully mature, the fruit turns light green and light yellow, and the sutures between the small fruits are obvious, harvest the seeds. As grafting rootstock shaping, seed collection can reduce standards. After removing the seeds, wash them to remove false and hard seeds, dry them before sowing. The seeds for spring cultivation in the second year should be completely dried, and then placed in polyethylene plastic bags and sealed for storage. Length of sowing time for custard apple

In areas with relatively high winter temperatures, custard apple is best planted in August to September after the seeds are picked and dried. The emergence rate of fresh seeds is relatively high, and the growth period of green seedlings is long, which is beneficial to cultivation. Strong seedlings. In order to cultivate strong seedlings, you can soak the seeds with 200 mg of auxin for 24 to 36 hours before sowing. The seeds can germinate 3 to 5 days earlier. After the seedlings have 6 leaves, use love to harvest 5000 to 6000 times more leaves. Spraying the leaves twice can be effective. Improve seedling growth rate.

Because custard apple seedlings are more sensitive to frost, autumn seedlings need to pay special attention to anti-freeze and heat preservation work. In addition, in subtropical climates, it is best to sow in spring. It is generally better to sow after the local low temperature and rainy weather has passed and the weather has stabilized. How to sow cherimoya

Stored cherimoya seeds should be sun-dried before sowing to promote germination. The seedling base should be sunny, with good drainage and rich sandy soil, preferably on hilly terrain and flat ground. Before sowing in the nursery, the ground should be sun-dried for 1 to 2 months. Then use retting organic fertilizer and a little lime powder as base fertilizer, crush and mix, and then build furrows and borders. Hole sowing or broadcasting can be used. 7~8Kg of seeds per mu are used. Cover with river sand or fine soil, tamp it lightly and then soak it with water and cover with grass or plastic film. Pay attention to moisturizing and replenishing water during the seedling stage. At the same time, you are afraid of water accumulation, so you need to pay attention to resolutely avoid too much water to prevent brown spots. sick. After germination, remove the grass or plastic agricultural mulch to prevent the seedlings from bending.

Seed treatment: The seeds can be sown after being removed, washed and dried. If they are not planted for a long time, they must be completely dried and sealed for storage. Sowing: Generally sowing in spring, if the temperature is low, you need to pay attention to keep warm. Since custard apples are also very susceptible to diseases when growing, the seeds can be soaked with 200 mg of auxin for 24-36 hours before sowing, so that the custard apples will have the best resistance to pests.

Soil layer: Loose, rich, and well-drained sandy soil must be selected for planting. In addition, because custard apple is a tropical rainforest plant, the planting temperature requirements are relatively high. If sowing in autumn, anti-freeze and heat preservation measures are also needed. Watering and fertilizing: In the early stage, watering is generally done once every 3 days. In hot weather, you may consider increasing the frequency of watering, and then carry out effective fertilization based on the growth and development of the cherimoya.
