How long does it take for Sakyamuni to blossom and bear fruit?

Seedlings usually begin to bear fruit 2-3 years after planting. The flowering period is May-June, and the fruiting period is June-165438+1October.

cultivate

Biological characteristics, like tropical climate, the annual average temperature is above 20℃, not cold-resistant; Suitable for planting in loam with fertile soil and good drainage.

Cultivation techniques, mainly seed propagation and spring sowing; It can also be propagated by grafting or budding. First, planting 3-4-year-old young trees at the top of the trunk can promote the growth of lateral branches and improve the fruiting rate.

Pest control: if the longicorn beetle harms the trunk, it can dip a cotton ball with 5 times of 90% trichlorfon solution into the viscera of the wormhole, and then seal the larvae with mud to kill them; 50% malathion emulsion 1000 times solution can control fruits damaged by scale insects.

mature period

Hainan produces all the year round, and the main fruit ripens in June 6- 10/October165438+1October.

Annona is a kind of tropical fruit with sweet fruit, which is listed as one of the famous tropical fruits with its unique fragrance. Mature fruiting plant annona squamosa

Pale green and yellow, the appearance is raised by a soft wart with a polygonal little finger (there are many mature ovaries and receptacles), just like a Buddha's head, so it is called Buddha's head fruit and Sakyamuni fruit.

Breeding mode

sow seeds

The use of seedlings in production is limited to ordinary annona, and hybrid annona cannot be used as mother tree. The seed source of seedlings is very important, and the seeds should come from high-yield and high-quality fruits of excellent varieties (common annona), with large mother plants and correct fruit shapes.

It is best to artificially pollinate fruits of the same variety. When the fruit is completely mature, the fruit is light green and yellow, and the suture line between small fruits is obvious, the seeds are harvested. As a grafted rootstock culture, seed collection can reduce the requirements.

After the seeds are taken out, they are washed, the weak and small seeds are removed, and then they can be planted in the air. For example, stored annona seeds should be dried before sowing to promote germination. Before sowing, seeds can be soaked with 200ppm gibberellin for 24-36 hours to promote early germination.

It is best to use fertile sandy loam for seedbed, and apply decomposed organic fertilizer to shake well. The furrow should be opened, and the width of the furrow shall be subject to the convenience of field operation. Drill sowing can be used, and the sowing amount is 7-8 kg per mu.

After sowing, cover with fine sand or fine soil, slightly compact and drench with water, then cover with grass or plastic agricultural film to keep moisture. After emergence, cover with grass or plastic film to avoid bending the seedlings.

Pay attention to water and fertilizer management at seedling stage, generally water once every 3-4 days and once a day in drought. After 6-8 leaves, topdressing can be started to cultivate strong seedlings. ?

transplant

Common annona squamosa is generally used as rootstock for grafting seedling. This kind of rootstock has the characteristics of good affinity, short tree shape and early production. The thickness of rootstock is generally about 0.8 cm before grafting.

Grafting time: Grafting is generally in spring, bud grafting is better in summer and autumn, and grafting in winter generally cannot survive. The scion of annona squamosa is selected from the peripheral branches of excellent mother trees with strong growth and no pests and diseases.

After the scion is picked, the leaves are cut off, and the petiole with a length of 0.3-0.5 cm is reserved to reduce the evaporation of water. This method is suitable for the sap flow period of the growing season, so that the rootstock can peel off the bark.
