High-yield planting method and technology of celery

Celery is a new type of nutritious and health-care vegetable introduced from abroad in recent years. It has many functions such as lowering blood pressure, calming, diuretic and promoting appetite. It is very popular in the market. Let’s learn about the planting management of root celery. technology.

Celery

1. Nursery method

For celeriac seedlings, you can choose to use plugs to grow seedlings or use seedbeds. If you use plugs to grow seedlings, the survival rate of the seedlings will be higher, the quality is good, the disease is very well controlled, and there is no weed There is no need to slow down seedlings after planting, which is very helpful for growth, but because the cost of plug seedlings is somewhat high. Therefore, it is only suitable for large-scale planting parks. If you use a seedbed to raise seedlings, you can use some flat or small high, and then rake the bed soil to level it out. Remember to apply enough fermented base fertilizer, and also remember to pour foot water.

2. Seed soaking

Celery can be sown in suitable seasons. Seedlings usually grow about ten days after sowing. If the temperature is too high or too low, you should use the seed soaking to accelerate the germination, especially in the summer when the seedlings are raised. If you do not carry out the germination, it is difficult to germinate. The general soaking time for root celery seeds is between 12 hours and 24 hours, and the germination temperature****** is 15°C to 20°C. In the refrigerator, cold storage or well, germination is all right. During the germination period, remember to wash once a day and dry the water. This is good for ventilation, and the germination can be achieved in about eight days.

3. Sowing

If you are using plug seedlings, if you use a 128-hole plug, then sow two to three seeds in the MG blood. You need to sow 60 trays per acre. If you use a seedling bed, each You need 20 meters of seedling borders per mu of land, and plant them as thinly as possible. This can help you save the process of separating seedlings. It can also reduce damage to the root system.

4. Seedling management

After emergence, you can put a layer of fine soil on it, which will help preserve moisture and strengthen seedlings. When fertilizer is used in the seedling stage, two or three seedling fertilizers are generally used, but the specific situation still depends on the fertility of the soil itself and the growth of the seedlings. In addition, during the seedling stage, attention should be paid to weed pulling and thinning, as well as to prevent the infestation of toothworms, whitefly and other pests. You can spray pyrethroid insecticides once every 7-10 days.

5. Soil preparation and fertilization

4000 to 5000 kg of decomposed organic fertilizer should be applied on each mu of land. Then add 30 kg of superphosphate and 10 kg of potassium sulfate. Finally, deep turn or use a rotary tiller to rake. Make a flat frog about 1.5 meters wide and about eight meters long. Remember to rake and flatten the noodles after you are done, and then you can wait for the planting.

6. Colonization management

After sowing for about 60 days, when the seedlings grow to six or seven leaves, they can be planted. Before planting, you need to irrigate them one day in advance. This will help you minimize the damage to some roots when the seedlings are raised. The plug seedlings also need to be watered one day in advance, which is good for picking the seedlings. When preparing flat borders for planting, for those early maturing varieties. We need a border with a width of 1.33 meters, about 4 rows of plants, and the spacing between each plant is 33cm, and about 5000 to 6000 plants can be planted per mu of land.

7. Field management

In two to three days after planting, water the slow seedling water once. One month after planting, we will also water, and at the same time, we will also apply about 10 kilograms of urea per mu. During the swelling period of fleshy roots, you should evenly water more water. At the same time, you should also timely supply potassium fertilizer and about 20 kg of three-element compound fertilizer. During the growth period, we need to remove old leaves and some side branches in time. This is very helpful for ventilation and light transmission.

8. Harvest in time

When the root ball of the rhizome grows to about 0.5 kg, it can be harvested. When we harvest, we must first break off the outer large leaves, and then remove the roots. Because the root celeriac grows slowly, and there are differences between individuals, we can harvest some large ones when harvesting, and leave those small ones to continue to grow. The harvest period of the root celery can not be too early or too late. If it is early, the yield will be very low. When it is too late, it is easy to appear hollow or actually form a hollow during storage. Generally, it can be stored for two months at 0℃ to 5℃.
