The latest course of cultivation techniques of ash tree

Ash tree, also known as green hammer tree, bauhinia tree, it is a kind of tree, widely planted in our country. This means that the environment in various regions of our country is basically in line with the growth conditions of ash trees, and the technology of planting ash trees is basically mature. So today, the editor will give you a brief introduction to the planting process of ash and its cultivation methods.

1. Cultivation environment

Ash likes warmth, light, saline-alkali tolerance, moist and fertile, and does not have too many requirements for soil. But it grows better in neutral, fertile, sandy loam. After selecting the planting site, dig deep into the soil, clean up the impurities, insect pests, tree roots and weeds in the soil, knock the clods fine and level off, and then you can plant them. Of course, in order to better manage, then we also need to open a good ditch.

2. Seedling cultivation

Ash trees are usually sown between the end of March and the beginning of April. Before sowing, we need to accelerate the germination of ash seeds, which can be divided into two types: low temperature and high temperature. After the seeds are germinated, strip sowing is carried out in trenches at a distance of 10 to 20 centimeters between rows. The seeds are evenly scattered in the ditch, and then covered with soil to cover the seeds. To keep the soil moist during seed germination, you usually need to water every two to three days and clean up the weeds in the field.

3. Water and fertilizer management

After the ash tree is planted, we should pay attention to watering thoroughly, and then water it again in about four or five days, and then water it scientifically according to the growth of ash tree and the rainfall in the later period. In order to restore the ash tree quickly, we have to keep the soil moist and wait until the next spring before pouring back green water. Secondly, in order to promote the growth of ash tree, we should apply fertilizer scientifically. In the early growth stage of ash tree, it is mainly nitrogen, phosphorus and potassium fertilizer, while in the later stage, it needs to be combined with farm manure or organic fertilizer. Finally, it should be noted that when applying chemical fertilizer, it is best to water after topdressing, so that the phenomenon of fertilizer damage can be avoided.

4. Pruning and shaping

Pruning and tree-shaped arrangement of branches and leaves is an important link in the process of seedling planting. Before planting, we need to prune the seedlings, such as some weak roots, extra branches and leaves, and so on. After the planting has survived, in order to promote the growth of the main branches of the ash tree, we will prune the ash tree appropriately, and slowly cultivate the secondary branches, and wait until the secondary branches are cultivated, and then continue to cultivate the lower branches until a complete tree shape is formed. After the ash tree forms a complete shape, we still need continuous pruning in the later stage, just to maintain the tree potential and promote the growth of the ash tree.

5. Disease and pest control

The main pests of ash trees are ash bugs, aphids and longicorn beetles, which do great harm to the growth of ash trees. When no pests are found, we can spray stone-sulfur mixture to prevent them. After the occurrence of insect pests, it is necessary to use carbendazim or carbendazim with insecticides to kill insects. The most common diseases are brown spot and coal fouling, which can be controlled by Bordeaux solution and pesticides.

This is the end of what the editor wants to share with you today. I believe that through the reading above, you also have a general understanding of the planting of ash trees. I hope it can help the friends who plant ash trees.
