How to plant elm

Elm, also known as white elm, is known as "elm pimple". It has high ornamental value, not only cold resistance, but also anti-pollution and strong dust retention ability of leaves. At present, it is mostly planted on green land and on both sides of the road. How to plant elm?

1. Soil requirements

It is best to choose a more loose soil to plant, before planting, we have to carry out weeding treatment, so that the survival rate of elm is higher. It should be noted that the soil had better be fertile.

2. Sowing seeds

The main results are as follows: (1) sowing time: Elm seeds are generally sown in the way of picking and sowing. In the middle of April every year, the seeds can be collected at the right time, and sown according to the weather conditions.

(2) seed selection: Elm seeds can choose the seeds harvested in the same year, but we must pay attention to screening the seeds to leave high-quality seeds, and you can also go to professional seed companies to choose. In this way, you can choose more suitable quality according to your local climatic conditions, and the quality is also more guaranteed.

(3) sowing method: most of the elm seeds are sown by strip sowing, which is relatively simple and easy to manage in the later stage, generally preparing about 4 kg of seeds per mu.

(4) sowing method: generally, after opening a ditch to sow the seeds, the covering soil can be pressed properly to ensure the full combination of the seeds and the soil. in addition, if the soil is relatively dry, do not irrigate the flood, it is best to use the method of spraying the surface to avoid washing away the seeds with too much water. When the seeds sprout, the seedlings can be unearthed in about 10 days, and when the seedlings grow to about 2-3 cm, we need to set the seedlings, usually when the height of the seedlings reaches 5-6 cm. In addition, it is relatively simple for the daily management of watering, fertilization and weeding at the seedling stage.

3. Transplanting

Roots need to be thoroughly into the soil, to be planted more positive, must not have the phenomenon of skew, at the same time, we must trample after planting in the soil, which 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, each watering to ensure that the soil is moist, 3 months later, we can choose once a week.

(2) rational fertilization: generally speaking, it is better for us to apply fertilizer one week after planting, and it is better to choose organic fertilizer. When applying fertilizer, we should not apply fertilizer towards the root, but towards the edge of the root.

(3) pruning: the main pruning is the lower branch, and the general branch will wither and yellow. we need to cut it off. if it does not appear, we also need pruning if we want the elm to grow tall and strong.

(4) Cold protection: in winter, we had better brush white to protect elm trees from frostbite or death, which we need to know.
