Planting techniques of root celery

Root celery is a kind of celery which mainly takes the root as the edible part. Root celery can be used not only for food, but also for juice extraction. It has the effect of reducing blood pressure, diuresis, increasing appetite and so on, and the aroma of ordinary celery is diluted, and the content of crude fiber is very low. It is very suitable for the elderly, so how to grow celery? The following editor brings you the planting technology of root celery, let's have a look!

1. Planting time

The planting time of root celery is mainly in spring and autumn, raising seedlings in greenhouse from February to March in spring, and then planting at the end of April. under normal management, harvest can begin in August. Or plant it at the end of April and do it again around November. Because the root of root celery is more suitable to live in a shady and humid environment, so in the planting process, the growth of root celery is healthier and the yield is higher in the environment of higher temperature. If the summer temperature is too high, then it is only suitable for planting in autumn.

2. Sowing and raising seedlings

The pericarp of root celery is hard, contains more oil, and its water absorption capacity is poor, so its germination ability is weak, the seedling is poor, and the germination rate is low. Therefore, it is very important to raise seedlings. Before sowing, it is necessary to do a good job of seed soaking and sprouting. The water temperature is controlled at about 25 degrees and soaked for about 9 hours. Then wash the seeds, air-dry water, mix them with the soil and spread them evenly on the seedbed. The seedbed soil should be finely crushed and thoroughly watered after applying sufficient base fertilizer. To ensure that the seeds are in full contact with the soil, and then the temperature is controlled at about 20 degrees, strengthen management and promote seed germination.

3. Timely planting

Before planting, we should choose the soft, deep and fertile land as the planting field, and then do a good job of clearing the garden, turn the ground deep and apply appropriate amount of base fertilizer. After controlling the planting density, transplant properly, and be careful not to hurt the root of celery when digging seedlings. Because the recovery ability of root celery is poor, injury will affect the growth ability, cause a variety of diseases and insect pests, resulting in poor growth and death in serious cases. Therefore, when digging seedlings, we should transplant with soil as far as possible, which can not only ensure that the roots will not be hurt, but also continue to provide nutrition for root celery in the process of transplanting.

4. Field management

The growth of root celery is more like water, but when watering, do not flood irrigation, to increase the frequency of watering, reduce the amount of each watering. In the peak period of leaf growth, the principle should be that the ground should not be dry or watered. In the fleshy root expansion period, it is necessary to ensure sufficient water, and then appropriate topdressing, mainly phosphorus and potassium fertilizer, potash fertilizer can effectively promote the expansion of root celery fleshy root. Then do a good job of weeding in ploughing to prevent the hollow phenomenon of root celery, pick leaves in time, improve field permeability, avoid consuming too much nutrition and affect the growth of plants.

The above is a brief introduction to the planting technology of root celery, the growth ability of root celery is relatively strong, and it is relatively simple when planting. However, we should also pay attention to the prevention and control of diseases and insect pests to prevent fatal harm to root celery. That's all for today's introduction.
