What does elm use to spread its seeds?

Elm also known as elm money tree, there are "elm knot" said, more planted in the southern region, with anti-pollution, leaf dust retention ability is strong, that elm rely on what to spread seeds?

What does elm tree depend on to spread seeds?

Elms disperse seeds by wind. Generally, when the fruit ripens, the fruit will hang high on the treetops like a big knife. When the fruit cracks, the seeds will fly out and fly to other places with the wind. After the environment is suitable, they can take root and germinate.

2. How do elms grow?

1. Soil requirements

It is best to choose loose soil for planting. Before planting, we should carry out weeding treatment, so as to make elm survival rate higher. It should be noted that the soil is better fertile.

2. Sowing

(1)Sowing time: elm seeds are generally used to sow along with the harvest. After the elm is mature in mid-April of each year, the seeds can be harvested at the right time, and the seeds can be sown at the right time according to the weather conditions.

(2)Seed selection: elm seeds can choose the seeds harvested in the same year, but must pay attention to the screening of seeds, leaving high-quality seeds, in addition to professional seed companies to choose, so that you can choose more appropriate quality according to their local climatic conditions, and the quality is also more guaranteed.

(3)Sowing method: Most elm seeds are sown in a drilling way, which is relatively simple and easy to manage in the later stage. Generally, about 4 kg of seeds can be prepared per mu.

(4)Sowing method: Generally, after the seeds are sown, it is necessary to cover the soil with appropriate pressure to ensure the full combination of seeds and soil. In addition, if the soil is relatively dry, do not irrigate with large water. It is best to use the method of spraying the surface to avoid excessive water to wash away the seeds. When the seed sprouts, the seedlings can be unearthed in about 10 days. When the seedlings grow to about 2-3 cm, we will thin the seedlings. Generally, when the seedling height reaches 5-6 cm, the seedlings can be fixed. In addition, the daily management of watering, fertilizing and weeding at the seedling stage is relatively simple.

3. Transplanting

The roots need to be thoroughly planted in the soil. The planting should be relatively positive. There must be no skew phenomenon. At the same time, after planting into the soil, we must step on it. This we need to pay special attention to.

4. Management techniques after transplanting

(1)Reasonable watering: In the early stage, we can choose to water once every 2 days. Elm trees do not have a particularly high demand for water. We do not need to water every day. Every time we water, we can ensure that the soil is moist. After 3 months, we can choose once a week.

(2)Reasonable fertilization: Generally, it is better to fertilize one week after planting. Choose to fertilize with organic fertilizer. When fertilizing, we should not fertilize toward the roots, but toward the edges of the roots.

(3)Pruning: The main pruning is the lower branch, the general branch will appear withered yellow phenomenon, we need to cut off, if not, we want elm tall and strong words, also need to prune.

(4)Cold: In winter, we generally had better carry out whitewashing treatment, so as to carry out temperature protection, to avoid elm frostbite or freeze to death, this we need to know.
