The growth characteristics of coriander are characterized by short growth period and fast growth rate. If the soil fertility and water are sufficient, you can eat your own coriander in time. Soil selection requires loose and fertile soil, and appropriate amount of base fertilizer and farmyard manure can be added, provided that soil is mixed to prevent the phenomenon of less seedlings caused by excessive fertility.
The origin of coriander is the Mediterranean region of Europe. According to legend, Zhang Qian was brought back from the western regions of China in the Western Han Dynasty (BC 1 century) and is now cultivated in Northeast China, Hebei, Shandong, Anhui, Jiangsu, Zhejiang, Jiangxi, Hunan, Guangdong, Guangxi, Shaanxi, Sichuan, Guizhou, Yunnan, Tibet and other provinces.
Growth temperature of coriander The suitable growth temperature of coriander is 17℃ to 20℃, and it can tolerate the low temperature of-1℃ to 2℃. When the temperature exceeds 20℃, the growth is slow, and it stops at 30℃. Coriander is not strict with the soil, but the soil with good soil structure, strong fertilizer and water retention performance and high organic matter content is beneficial to the growth of coriander.
Is coriander resistant to high temperature? Coriander is a very heat-resistant vegetable. The hottest dog days in summer can still be planted. Because the seed shell of coriander is very hard, it is necessary to rub the seeds hard before sowing, and then soak the seeds properly, so that the sown coriander can germinate as soon as possible and save seedling time.
What is the minimum cold tolerance of coriander? The low temperature tolerance of coriander can adapt to-0/degree to above 3 degrees, but the most suitable temperature for growth is 1 degree to 20 degrees, which is the normal temperature in temperate regions, so it is suitable for cultivation in temperate regions. Growth will slow down if it exceeds 20 degrees. Therefore, it can also be cultivated in autumn, winter and spring in subtropical areas.
What temperature can I grow coriander? The average annual temperature in common parsley planting areas is 8 degrees-12 degrees. Coriander also has high requirements for water conditions, and growers should ensure the water supply and irrigation of coriander in dry season.
The growth process of coriander can be vernalized after 10 ~ 20 days at a low temperature of 2-5 degrees under general conditions. Later, under the condition of long sunshine, bolting was carried out through photoperiod. The growth period from sowing to harvesting is 60-90 days.
The planting method of coriander 1, seedling raising: soak the seeds in warm water for ten hours, and then press the shell open easily. Generally speaking, it can be planted in spring, summer and autumn, and it can emerge in about ten days.
2. Soil: When planting coriander, we should pay attention to choosing a soil with good fertility and water retention, which is beneficial to the growth of coriander root system.
3. Fertilizer: The root system of this crop is relatively shallow, so it is necessary to apply base fertilizer in advance to better meet its nutritional needs. It is suggested that organic fertilizer should be given priority.
4. Moisture: The growth of coriander requires high moisture, so water should be poured every other week to avoid the soil being too dry.
5, lighting: In addition, when the weather is very hot, it is best to set up a parasol to avoid strong sunlight burning coriander.
