How to plant longan (longan) seeds? How does it sprout? Will it work out?

Longan also known as longan, intelligence. China's southwest to southeast cultivation is very wide, with Guangdong Sheng. How do you plant your seeds? How does it sprout? Will it work out? It is understood that longan trees planted with seeds will also bear fruit, but compared with grafted seedlings, the results will be delayed for three or four years, and the quality may not be excellent. Due to the large variation of seed reproduction and late entry into fruiting period, seedlings are generally not used in production and cultivation, but grafted seedlings are mostly used. The seeds are usually planted in potted plants.

How do seeds sprout? How?

1. After eating the flesh, remove the flesh and white soft tissue at the top of the core, otherwise it will be easy to attract insects in the future;

2, the longan seeds soaked in water, water submerged seeds can be, every day to change the water to no impurities. After soaking for 4~6 days, the shell will crack slightly, and the bud point (white part after cracking) can be seen, and then planting can be carried out. After the shell cracks, soak for 2~3 days to accelerate the emergence of new buds.

3, choose a suitable hole-free pot, put in sterile culture soil, about eight minutes full, and spray some water to the soil on the surface to make it moist, spread the seeds on the surface, one by one without spacing. Select seeds with similar dehiscence and plant them in the same pot, so that germination will be more consistent. Fill the gaps with some culture soil and cover the seeds. Then cover the surface with medical stone or other small stones. After spreading, gently press the surface with your palm to make the seeds more stable. Then use a water sprayer to spray back and forth three times, and then remember to spray water once a day.

4, wait for the next germination, about 8 to 10 days after the new buds can all come out.

Add: Longan (longan) cultivation method

1, spring planting can be in 2~3 months, winter planting can be in late October. Planting density: row spacing 16m, plant spacing 4.5m, planting 19~20 trees per mu. The planting hole with depth of 1m shall be dug first, and river mud shall be applied under it. Compost, calcium superphosphate and plant ash should be mixed with topsoil. After planting, it must be fully irrigated first, covered with fine soil after irrigation, and then irrigated 1~2 times a day. Planting depth, root neck should be flush with the ground.

2. Adopt natural flat circular shaping, stem at 1.2~1.3m on the ground in the second ~ third year after planting, cultivate 5~7 main branches in 3~4 years, and finally remove the center. Pruning 3 times a year, the first flowering period pruning, mainly cut off the disease ear, shade branches and file branches. The second pruning is carried out during fruit picking, mainly cutting off short fruit branches, excessive branches, diseased branches, dead branches and shade branches. The third time in winter, mainly cut off shade branches, dead branches and diseased branches.

3. Apply base fertilizer once a year and topdressing 3~4 times. The first topdressing in February to March, manure and ammonium sulfate, etc. The second topdressing is in the young fruit stage after flowering, about 4~5 months, mainly nitrogen fertilizer, appropriate phosphorus and potassium fertilizer. The third topdressing was carried out from late June to early July, mainly phosphorus and potassium fertilizer, followed by nitrogen fertilizer. In the fourth fertilization, nitrogen fertilizer was still dominant when the fruit was close to maturity. Fertilization method is 30cm away from the trunk of the furrow into the. Fertilization can be combined with cultivation, weeding, cultivation and irrigation.

4. Pest control: litchi Chinese toon, brown beetle, small gray butterfly, flame silk moth, scorpion longicorn, longan tree trunk moth, post-yellow leaf roller, longan bag moth: diseases include ghost broom disease, lichen and rubber disease, which should be controlled.
