The Latest Guide to High-Yield Celeriac Cultivation and Management Techniques
Celeriac, as the name suggests, is root celery, a new type of nutritious and health-promoting specialty vegetable introduced from abroad in recent years. It has effects such as lowering blood pressure, calming, promoting diuresis and stimulating appetite. Its fleshy root and leaf stalks are mainly used, and its nutritional value is higher than that of traditional celery. So if you want celeriac to be high-yielding, how should it be grown? Let's learn about it together.
1. Raising seedlings
Celeriac seeds are small, and the seed coat is leathery and oily, so they absorb water slowly and take a long time to germinate. The suitable germination temperature is 15 - 20°C. Below 4°C or above 25°C will make germination difficult and result in a low germination rate, so attention should be paid during seedling raising. Generally, germination is promoted before sowing, and plug tray seedling raising or seedbed seedling raising can be chosen. After emergence, water management can be relaxed slightly. For seedling raising in flat beds, a layer of fine soil can be covered after emergence to help preserve moisture and stabilize the seedlings. During the seedling stage, pay attention to weeding and thinning, and apply 2-3 seedling-promoting fertilizer dressings according to the seedling field. Pay attention to the fertilizer concentration. At the same time, also pay attention to pests and diseases. Spraying a pyrethroid insecticide once every ~10 days is enough. Under suitable conditions, the seedlings can be lifted and transplanted in about 60 days.
2. Land preparation and fertilization
Choose fertile and loose soil as the transplanting site. Apply 4000-5000 kg of decomposed organic fertilizer, 0 kg of superphosphate and 10 kg of potassium sulfate per mu as base fertilizer. After deep plowing and raking level, make flat beds. After raking the bed surface level, it is ready for transplanting. Because the swollen part of celeriac is at and above the ground, there is no need to choose the high-ridge cultivation method.
3. Transplanting
One day before transplanting, water thoroughly to avoid damaging the roots too much when lifting the seedlings. Plug tray seedlings should also be watered one day in advance to help lift the seedlings. If pests or diseases are found, apply pesticides in a centralized way before transplanting. For flat-bed transplanting, early-maturing and mid-maturing varieties are planted in 4 rows per bed, with a plant spacing of about 33 cm, and 5000-6000 plants per mu; late-maturing varieties should have appropriately increased plant and row spacing, with about 4000 plants per mu. Do not transplant too deeply; just bury the root part. Water immediately after transplanting.
4. Field management
2-3 days after transplanting, water once to help the seedlings recover. When soil moisture is suitable, carry out intertillage and loosening. After that, keep the soil moist. One month after transplanting, water and apply one fertilizer dressing, applying 10 kg of urea per mu. When the fleshy root expands, water more, and at the same time pay attention to the supply of potassium fertilizer. Combined with watering, apply a three-element compound fertilizer once every 1-2 times, 20 kg per mu each time. During the growing period, promptly remove old leaves and side branches to improve air circulation and light penetration. When the fleshy root expands, the root soil can be pulled open and a small knife used to cut off shallow lateral roots so that the main root becomes thicker. After cutting, do not water, so as to avoid wound infection and rot.
