Luan tree sowing and propagation

Picking fruit

The fruit of Luan tree usually matures from September to October. Plants with good growth, full fruit and strong growth age should be selected as seed collection mother trees. Collect the fruit in time before it falls off, but do not pick it too early, otherwise it will affect the germination rate of seeds

Planting treatment

Remove the peel and stem of the collected fruits, dry them in time, knock them after they crack, and then clean them with screening method

Luan seeds should be soaked to improve the germination rate of seeds

Seeding management

Luan tree should choose the land with high terrain, good drainage and sunny wind when sowing in autumn. The soil should be loose and breathable, and the land preparation should be flat and fine

Sufficient base fertilizer shall be applied on the selected land, and the seeds shall be sown in the way of drill sowing. After sowing, the seeds shall be covered with shallow soil to prevent the seeds from drying and losing water or being harmed by birds and animals. It is also necessary to water the soil once and cover the ground with grass and straw, which can improve the low temperature and keep the soil moist

Intercropping management

When the seedlings grow to five to ten centimeters, they should be intercropped. The principle of intercropping is to leave small ones for large ones and dense ones for sparse ones. It is best to do it in cloudy and rainy days

Fertilization management

After the seedlings have long roots, nitrogen fertilizer can be applied in their growing season to promote the rapid growth of seedlings; Applying phosphorus and potassium fertilizer after autumn can effectively improve the lignification degree and cold resistance of plants< span>
