The latest method of raising longan seedlings

Longan is a very popular fruit, its nutritional value is relatively high, with nourishing health, tonic heart and spleen and other effects. It is a fruit that is edible and medicinal. In tropical provinces of our country there is a very wide cultivation area. Longan seedling planting work is very important, the most common longan seed seedlings. So Xiaobian brought you the seedling method of longan today. Let's take a look at it together!

1. Land selection and fertilization

Longan seedbed should be selected in normal irrigation, flat and thick soft soil, fertility sufficient soil. After selecting the soil, the soil preparation should be carried out to remove stones, previous crops, etc. from the field. Then turn the soil about 26-29 cm deep and dig furrows. When preparing the soil, we should also apply sufficient base fertilizer, which is mainly decomposed farm manure, combined with calcium, magnesium and phosphorus nutrients, and fully ferment it. Then mix the fertilizer with the soil and mix well with the topsoil before preparing for sowing.

2. Seed treatment

Longan seed seedlings to ensure that full, not to let its dry shrink. When sowing, the pulp and mucus on the seeds should be cleaned, and then the inferior seeds should be selected to ensure the overall quality of the seeds. Soak the seeds in water to germinate, spread a layer of sand in a cool area after soaking, put the seeds flat on the sand, then put a layer of sand on the seeds, and then cover the grass to keep the moisture of the seeds and improve the germination rate. Germination temperature should be maintained at about 25 degrees, not too high, to prevent high temperature caused by loss of seed activity, about 4 days later, most of the seeds can be sown when white.

3. Timely sowing

Before sowing, we should first dig the seed hole, and the plant spacing of the seed hole should be controlled at about 30 cm. Put one seed into each sowing hole, cover it with fine soil after sowing, and then cover a layer of grass on the ridge surface to improve the water retention ability and prevent water shortage. Promote seed emergence as soon as possible, we should control the number of seedlings according to the planting area, generally the best number of seedlings per mu should be about 6500. If the seedlings are too dense, the thickness of longan trees will be affected. And it will reduce the survival rate of transplanting and the expansion speed of crown after survival.

4. Seedling management

When longan is sown, it is generally in summer, and the high temperature environment is very unfavorable to the growth of longan seedlings. So we can plant some green manure such as soybeans in the field before sowing. When the green manure grows to about 20 cm, it is the sowing time of longan. At this time, the use of green manure can provide a good shade for longan seedlings, which can improve their survival rate. When the temperature gradually drops, green manure can be pulled out and covered on the surface of the bed as fertilizer. Then when the longan seedlings grow 4 leaves and begin to turn green, we can cut the root of the taproot short. It can effectively improve customization survival and promote early results.

The above is a simple introduction to longan seedling methods. Longan seedling method is very important, we must pay more attention to planting. Today's introduction is here, this article is for reference only, I hope to help everyone oh!
