How to raise seedlings of Chinese prickly ash

Zanthoxylum bungeanum is eaten a lot in the south of China, and it is a side dish that many people like to cook. There is a large planting area in our country, but the prickly ash trees of some old growers are gradually aging and the amount of fruit is decreasing. Therefore, it is also necessary to properly raise seedlings to protect their own planting economic benefits, the seedling of pepper is very important. So how to raise pepper seedlings? The following editor brings you the seedling technology of Zanthoxylum bungeanum. Let's have a look!

1. Seed treatment

Choose Zanthoxylum bungeanum trees with strong growth, intact tree shape and free of diseases and insect pests for about 11 years. Then harvest it in time after the color of the fruit becomes darker and the pericarp cracked. After harvest, mix the seeds with cow dung, then expose them to the sun, dry them and then break them into pieces and store them in a dry place. The main purpose of this is to make cow dung absorb the oil from the seeds and improve the germination rate of the seeds. Then wash the seeds after taking out the seeds, remove impurities, soak them in detergent water for about 11 hours, and then put them in a dry and ventilated place to prepare for sowing.

2. Prepare the seedbed

The seedling bed of Zanthoxylum bungeanum should choose the soil with sufficient light, normal drainage and irrigation and no diseases and insect pests to ensure that the soil fertility is sufficient, soft and transparent. After selecting a good site, fine crush the soil, do a good job of deep ploughing, and keep its depth at about 30 centimeters. And at the same time of soil preparation, sufficient base fertilizer should be applied, which is mainly based on fully mature farm manure. After applying the base fertilizer, the cultivated land is ditched, and the main purpose of the box ditch is for the water and fertilizer management in the later stage. After doing a good job of the box groove, the box groove will be fine and raked flat to create a good growth environment for pepper seeds.

3. Sowing seeds at the right time

The sowing time of Zanthoxylum bungeanum seed should be chosen in spring and autumn, usually in March and November every year. Sowing methods are strip sowing, sowing, etc., strip sowing, then the row spacing should be controlled at about 22 cm to prevent planting too dense, and cover fine soil after sowing. If sowing, first spread the seeds evenly on the seedbed, and cover the fine soil after sowing. No matter which kind of sowing method, it should be suppressed properly after sowing, so as to promote the absorption of nutrient water and improve the emergence speed of seeds.

4. Seedling stage management

After the emergence of Zanthoxylum bungeanum seedlings, we should observe the growth of seedlings and do a good job of replenishing seedlings. The seedlings are interspersed for the first time when the seedlings grow to about 4 cm high. Then in half a month after the seedlings again, fixed seedlings should pay attention to remove the weak seedlings dead seedlings, make up for the same growth of healthy seedlings. And when the seedlings grow to about 9 cm, they begin to fix the seedlings. Do a good job of weeding in ploughing and strengthening the management of water and fertilizer to ensure that seedlings can grow normally, but water and fertilizer should not be excessive, otherwise it will have a certain impact on the growth of prickly ash.

The above is a brief introduction to the seedling technology of Zanthoxylum bungeanum, which is more important. The quality of seedlings is directly related to the growth of pepper, so we must pay more attention to it.
