Root celery is often referred to as root celery, which has a higher nutritional value than normal celery, and also has the function of improving appetite.
So what should be paid attention to in the process of root celery planting? Root celery planting how to high yield? The following with the editor to see it!
1, seedling
Root celery seeds are fine, seed leather texture is oily, slow water absorption, germination time is long, germination temperature at 15-20 degrees, below 4 degrees or higher than 25 degrees, will lead to its germination with difficult, germination rate is low, pay attention to when seedling.
General germination treatment before sowing, seedling can choose hole tray seedling or seedbed seedling.
After the emergence of seedlings, water management can be slightly relaxed, flat beds can be covered with a layer of fine soil after the emergence of seedlings, in order to facilitate the preservation of moisture and seedling fixation, in the seedling period, pay attention to weeding as well as inter-seedling, according to the seedling ground 2-3 times the seedling lifting fertilizer, pay attention to the concentration of fertilizer.
At the same time also pay attention to pests and diseases for ha, every ~ 10 days spraying once pyrethroid insecticidal pesticides can be, under the right conditions, 60 days or so can be planted seedlings.
2, land preparation and fertilization
Select fertile and loose soil as a planting site, per mu into the rotted organic fertilizer 4000-5000 kg, 0 kg of calcium superphosphate, potassium sulfate 10 kg as a basal fertilizer, will be turned over, harrowing, do flat beds, raking the beds, you can wait until the planting.
Because the root of celery expansion part in the ground and the ground, so do not have to choose the way of cultivation of high ridges.
3, planting
The planting needs to be watered thoroughly one day in advance, so as not to hurt the roots when starting seedlings, hole tray seedlings should also be watered one day in advance, which is good for seedling lifting, and if you find pests and diseases, you should concentrate on applying medicine before planting.
Flat bed planting, early and mid-maturity varieties planted 4 rows per bed, spacing 33 cm or so, 5000-6000 plants per acre; late varieties should be appropriate to increase the spacing between rows, 4000 plants per acre or so, planting should not be too deep to bury the roots can be planted immediately after the watering.
4, field management
2-3 days after planting, watering a slow water, in the soil moisture is suitable for ploughing and loosening, and then keep the soil moist, after planting in January, watering and fertilizer once, 10 kg of urea per mu.
In the fleshy root expansion, should be more watering, at the same time to pay attention to the supply of potash, combined with watering, every 1-2 times to chase the application of three yuan compound fertilizer, 20 kg per mu each time.
The old leaves and lateral branches should be removed in time during the growing period to facilitate permeability, and when the fleshy roots are expanding, the root soil can be peeled off, and the shallow lateral roots can be removed with a knife, making the main root fertile, and it is not advisable to water after cutting to avoid the wound becoming infected and rotting.
