How to plant Koelreuteria paniculata planting techniques and points for attention

There are many plants used as greening, so today we will learn about one of them, called Luanshu. Luanshu is a relatively common plant, mostly used for street tree cultivation, often able to see it on the road. Luanshu leaves in spring tender red, summer will become dark green, ornamental value is very high, deeply loved by everyone.

How to grow Koelreuteria

1. Seed collection: Koelreuteria fruits mature from September to October. Select good growth, stem shape straight, crown open, full fruit, in the mature stage of fine individual trees as seed collection mother tree, in the fruit is reddish brown or orange and capsule has not yet dehisced timely collection.

2. Fruit treatment: After fruit collection, it should be dried or spread in the shade in time. After capsule cracking, beat and thresh, and clean seeds by screening method.

3, seed germination: Koelreuteria seed seed coat hard, not easy to penetrate water, such as the second year without germination treatment spring sowing, often do not germinate or germination rate is very low. Therefore, it is best to sow in the autumn of that year, so that the seeds complete the germination stage in the soil, and the procedures such as seed storage and germination can be omitted. In the spring, the seedlings are unearthed early and neat, and grow healthily.

4. Sowing: Luanshu generally adopts field seedling. The sowing ground should have loose soil, good water retention and drainage performance, certain fertility, no underground pests and germs. spring-seeded

Koelreuteria planting techniques and precautions

I. Planting technology

1. Soil

When breeding koelreuteria, you need to pay attention to the soil, it can withstand barren and drought, but prefer to cultivate in calcareous soil.

2. Temperature

Koelreuteria tree adaptability to temperature is still very strong, more than minus 20 degrees are tolerable.

3. Watering

Koelreuteria is more resistant to drought, but not water and moisture, so pay special attention to watering.

4. Fertilization

During the peak growth period, nitrogen-based quick-acting fertilizer should be applied to promote the vegetative growth of plants. In autumn, nitrogen fertilizer should be stopped and phosphorus and potassium fertilizer should be added to improve the lignification degree of plants and the cold resistance of seedlings. In winter, organic fertilizer should be applied as base fertilizer, which not only provides persistent nutrients for seedling growth, but also plays a role in heat preservation and soil improvement.

II. Precautions

1. Luanshu is a positive tree species. It likes light and wet climate. It has no strict requirements on soil. It can be transplanted from the north and south. When transplanting Luanshu, it is necessary to choose a sandy soil site with good drainage and loose soil. Do not plant sticky disciples. When transplanting Luanshu, choose cloudy days or late nights, bring soil balls, irrigate water in time, and avoid water shortage of seedlings.

2. In addition to applying sufficient base fertilizer during transplanting, topdressing should be carried out during its growth period. Generally speaking, in the early winter of the planting year, combined with pouring antifreeze water, some decomposed fermented cow manure or sesame sauce residue can be applied. After flowering in the following year, some nitrogen, phosphorus and potassium compound fertilizers can be applied, and farm manure can be applied again in early winter. Later management can be carried out according to this method.

Management method of seedling stage of Koelreuteria paniculata

1. Shade

When breeding seedlings, we must pay attention to shade, but the specific method of shade should be determined according to the breeding environment, generally to protect seedlings from sunburn. Wait until the light is less intense and gradually expose yourself to light.

2. Daily management

In the cultivation of Koelreuteria seedlings, to live, often loosen the soil, keep the soil loose, reasonable watering to keep the soil moist, so conducive to its growth. Observe the growth of seedlings, appropriate to thin seedlings to make up seedlings, to ensure that plants have the best growth state.

Cuttage propagation method of Koelreuteria paniculata

1. Collection of cuttings

Koelreuteria can be collected as seed strips after autumn tree defoliation, or can collect long branches of Koelreuteria as seed strips, and bury the seed strips with wet sand or wet soil to keep the moisture of the seed strips.

2. Cutting cuttings

Take out the buried cuttings, cut them into equal length stem segments, and cut them obliquely to facilitate cuttage propagation.

3. Winter storage cuttings

To choose a shady place that is not easy to accumulate water for winter storage, put the cuttings in the dug sand ditch, and then cover half a meter thick wet sand.

4. Cutting

Select rich humus content, loose air permeability, good water retention soil, apply sufficient decomposed organic fertilizer as base fertilizer, cutting part of the exposed ground.

5. Post-insertion management

Maintain sufficient soil moisture, apply appropriate amount of nitrogen and phosphorus fertilizer, control water and fertilizer in the hardening period of seedlings, and improve the lignification degree of seedlings.

The tree is relatively easy to grow. It is itself a light-loving, cold-resistant plant, and its adaptability to the environment is also very strong. But this plant is a little different is that it does not tolerate flooding, so it is important to master the watering method.
