What kind of flower or fruit is this on the tree?

I'm happy to answer your question. This is the fruit of Luan tree. The capsule is purple-red, brown at maturity and blunt at the top. The tip is convex, the seed is nearly spherical, it blooms from July to September, and it bears fruit at 8- 10.

First, the growth environment of Luan tree

Luan Shuxi grows in calcareous soil, can grow in slightly acidic and alkaline soil, and can also resist salt collapse and short-term waterlogging. But it grows well in fertile, moist and deep soil.

Luan tree has deep roots, developed taproots, strong wind resistance, strong tillering ability, and is not tolerant to drought and barren pruning; The growth rate is moderate, the young trees grow slowly, and then gradually increase. Strong resistance to sulfur dioxide and smoke.

Second, the planting technology of Luan tree

1, migrating

Check before emergence, and the seeds will be unearthed 40 days after sowing. At this time, check the situation every day. After most seeds emerge, the mulch should be removed in time to ensure the healthy growth of seedlings and not wasted.

When the seedlings grow to two true leaves and the height of the seedlings is 5- 10 cm, the 1 th thinning and replanting are carried out according to the seedling density of the seedbed, so that the seedling density of the seedbed is reasonable.

2, fat water

Seedbed seedling should be combined with topdressing in time to fix the root system, and Vogen rooting agent can be applied to help Luan tree take more roots. Transplanted seedlings should be watered 1 time, and normal management should be carried out after delaying seedlings. It usually starts in early May and ends at the end of June.

Water management is generally based on soil moisture, and we usually observe the surface layer of soil. In the process of vegetative growth, the soil surface turns white, so it is necessary to replenish water in time to meet the growth needs of seedlings. In autumn and reproductive growth stage, water control and less watering are usually used to ensure the lignification of seedlings.

prune

In the first three years, the sprouting branches at the roots and the overlord branches on the trunk were cut off in time to ensure the growth of the main branches, and the branches mainly removed the branches that received less light at the lower part of the crown. Pruning should keep the crown equal to two-thirds of the tree height.
