Root celery high-yielding planting technique

Root celery is a new type of nutritional and health-care vegetable introduced from abroad in recent years. It has various effects such as blood pressure lowering, sedation, diuresis and appetite promotion. It is very popular in the market. technology.

1. Nursery methods

Root celery seedlings, you can choose to use plug trays to raise seedlings, or you can use seedling beds to raise seedlings. If you use plug trays to raise seedlings, the survival rate of seedlings will be higher, the quality is good, the disease is also very good control, and there is no grass damage Threatened, and there is no need to slow seedlings after planting, which is very helpful for growth, but because the cost of plug tray nursery is somewhat high. So it is only suitable for those large-scale plantation parks. If you use a seedbed to raise seedlings, you can use some flat borders or small high borders, and then rake the bed soil to make it smooth. Remember to apply enough fermented base fertilizer and remember to pour enough water.

2. Seed soaking

Root celery can be sown in seasons with suitable conditions. Generally, seedlings will grow about ten days after sowing. If the temperature is too high or too low, you should use seed soaking to promote germination, especially when raising seedlings in the summer, if you do not carry out germination, it is difficult to germinate. Generally, the time of soaking the root celery is between 12 hours and 24 hours, and the temperature for germination is preferably 15°C to 20°C. In the refrigerator, cold storage or well, it is possible to germinate. During the period of germinating, remember to wash it once a day, and also to dry the water, so that it is conducive to ventilation, and the buds can be germinated in about eight days.

3. Sowing

If you are using a plug tray to raise seedlings, if you use a 128-hole plug tray and then sow two to three grains in MG blood, you need to sow 60 trays per acre of land. You need 20 meters of Miaoqi on an acre of land, and try to sparsely plant them. This way, you can save you the need to divide seedlings. It can also reduce damage to the root system.

4. Seedling management

After emergence, you can apply a layer of fine soil on it, which will help to protect the soil and strengthen the seedlings. When using fertilizer at the seedling stage, generally use two to three seedling fertilizers, but the specific situation depends on the soil's own fertility and seedling growth. In addition, we should pay attention to pulling grass and thin seedlings, and preventing the attack of tooth worms, whiteflies and other pests, and spraying pyrethroid insecticides every 7-10 days.

5. Soil preparation and fertilization

4000-5000KG of decomposed organic fertilizer shall be applied to each acre of land. Then add 30 kg of superphosphate and 10 kg of potassium sulfate. Finally, perform a deep turn or use a tiller to harrow. It is made into a flat frog 1.5 meters wide and about 8 meters long. Remember to rake the flattened noodles when you are done, and then you can wait for colonization.

6. Colonization management

About 60 days after sowing, when the seedlings grow to six or seven leaves, they can be planted. Before planting, they need to be watered one day in advance. This will help you to reduce some roots as much as possible when you plant seedlings. The plug seedlings also need to be watered one day in advance, which is helpful for raising seedlings. When preparing for flat border planting, for those with early to medium maturity. We need 1.33 meters wide borders, about 4 rows of planting, the spacing between each plant is 33cm, and about 5000 to 6000 plants can be planted per mu.

7. Field management

Within two to three days after planting, water the seedlings once. After a month of planting, we also need to water, and also apply about 10 kg of urea per acre of land. During the period of fleshy root expansion, you should evenly pour some more water, and at the same time you should also supply potassium fertilizer and a three-element compound fertilizer of about 20 kg in time. In the growing period, we should remove old leaves and some side branches in time, this is very helpful for ventilation and light transmission.

8. Timely harvest

When the root bulb of the rhizome grows to about 0.5 kg, it can be harvested. When we are harvesting, we must first break away the outer large leaves, and then eliminate the fibrous roots. Because the growth of root celery is slow, and there are differences between individuals, we can harvest some big ones first when harvesting, leaving those small ones to continue to grow. The harvest period of the root celery should not be too early or too late. If it is early, the yield will be very low, and when it is too late, it will easily appear hollow or actually form hollow during storage. Generally, it can be stored at 0℃ to 5℃ for two months.
