So the demand has risen dramatically and the economic benefits are high.
Below we understand how and when to plant cilantro, see how to plant coriander.
Coriander planting time cilantro sowing and harvesting requirements are not strict, generally divided into spring, summer, fall and overwintering cultivation, the growing period of 60-70 days, can be calculated in accordance with the requirements of the market forward 60-70 days can be.
Spring open field planting: South China in l ~ February, Northeast, North China and Northwest China to March-April, Henan March sowing.
Summer planting: sowing in May-June, eastern Henan in early and mid-June, 40-60 days to harvest, voltaic market.
Autumn sowing: Northeast China sowing in mid-July to early August, North China sowing in late August to early September, eastern Henan sowing in late July to early August.
Harvesting in the pre-freeze or fall.
Wintering cultivation: North China sown in late September to October, harvested in March-April of the following year.
Cilantro planting methods cilantro cold hardiness is relatively strong, can withstand -12 - 1 ℃ low temperature, the growth of the appropriate temperature of 15-20 ℃.
Long sunshine for more than 12 hours can promote reproductive growth, easy to draw and flower; 12 hours below the short mouth of the light on the nutritional growth is favorable, the clump of leaves grows vigorously.
The light requirements are not strict, but photosynthesis is strong under medium light conditions.
Therefore, fall sowing is the best season for cilantro production.
The main cultivation technical measures are: (l) sowing method: can be sown or sown in strips, generally multi-row sowing.
Before sowing the seeds rubbed open, to avoid double seedling growth in the up, the best soaked seed germination sowing, seedling fast and Qi, germination temperature to 20-25 ℃ is appropriate.
Strip sowing row spacing of 8-10 centimeters, sowing width of 5-6 centimeters, ditch depth of 2 centimeters, uniform sowing, mulching and watering, pay attention to prevent the water from washing out the seeds.
Spreading after watering the bottom of the water, evenly spread the seeds, mulch 1.2 cm thick.
(2) field management: seedlings out of the ground, to prevent weeds, to keep the soil moist, watering should not be too much, the first inter-seedling in the plant height of 3-4 centimeters, spacing 2-3 centimeters of water; the second inter-seedling in the plant height of 6-7 centimeters, spacing 4 to 5 centimeters.
In the plant height of 9-11 cm into the growth period, this period should be strengthened fertilizer management, keep the soil moist, every 5-6 days to irrigate a small water.
(3)Fertilizer method: the 1st fertilizer after the 2nd inter-seedling.
Mu 5-6 kg of urea or dung diluted 1000-1500 kg, seedling height at about 15 cm when the second fertilizer, mu 10-15 kg of urea, the third fertilizer about 15 days before harvest, mu 8-10 kg of urea. Throughout the growing period every 10-15 days foliar spraying Sunbird compound foliar fertilizer 1 time, 50 grams per mu, 30 kg of water, the effect of yield increase is very significant and have a cold, drought effect.
