Cultivation technology of high yield coriander

Hi cold, growth temperature 15-18 ℃. It is a long-day crop. Long-term sunshine of more than 12 hours can promote development. Under short-day sunshine conditions, it needs to pass a lower temperature below 13-14 ℃ to bolt and bloom. Coriander is more adaptable, and the plants in the vegetative growth period can not only withstand the scorching heat, but also withstand the severe cold for a long period of time under simple covering conditions. Therefore, it can be cultivated throughout the growing seasons in China, but the autumn cultivation with shorter sunshine and lower temperature has high yield and good quality. In the south of China, the plant can be exposed to the winter, and the north can be stored for a long time.

Cultivated coriander can be broadcast live, before planting combined with site preparation, apply organic base fertilizer, rake flat after flattening. The fruit used for sowing needs to be rubbed apart to separate the seeds. Seeding or spreading. The sowing amount per mu is 1.5-2.0kg. Keep the soil moist after sowing, seedlings unearthed in 7-8 days, 3-4cm seedling height weeding and sparse seedlings, keep the plant row spacing 5-8cm. After the plants are sealed, increase the irrigation volume and top dressing 1-2 times at the same time. 50-60 days after sowing, * the leaves are harvested when they are 30-40 cm long. Coriander, which is retained, is sown in northern China more than September to October, and seedlings (4-5 true leaves) are overwintered under mulching conditions. Sparse seedlings resumed growth in the following spring and the plant spacing was 20-30cm. The fruit is ripe and harvested in time in June. It is sown in early spring in southern China and seeds can be harvested that year.
