Coriander is a popular seasoning vegetable. Many people like it. It is rich in nutrients and has a large market demand. However, many farmers who grow coriander in spring find that coriander is easy to convulsion. Why is this? How to pay attention?
First, the reason for spring coriander convulsions
Coriander is a cool climate. We usually grow coriander and choose to plant in autumn. It will be planted in early August and will be harvested in mid-September. There are not many coriander in spring, because spring coriander is easy to convulsion. In the early stage of coriander growth, the temperature is still relatively low, but the sunshine time is shortened and long, which is conducive to the reproductive growth of coriander and convulsions.
Second, the considerations of coriander twitching
1, variety selection
The large-leaf varieties that are resistant to convulsions, such as Shandong big leaf, are strong in resistance to large-leaf varieties such as Xiangshuai, Milan, and Australia. These varieties are generally not produced within 40 days after emergence, and the plant height is 30cm. It is easy to twitch, but the taste of the big leaf parsley is relatively light and not very popular. We can plant some small leaf varieties in the fall, they are rich in flavor and taste good, but they are easier to convulsion.
2, soil preparation
If the soil is poor in the spring, the water is insufficient, and the nitrogen is insufficient, then the nutrient growth of the coriander is not good, and it is easy to turn into reproductive growth, thereby convulsing and flowering. Therefore, in the spring, we must choose fertile soil for coriander, and apply organic fertilizer, mainly decomposed manure. Generally, 3 tons of decomposed chicken manure and 80 kg of NPK fertilizer are applied per mu.
3, mastering the sowing date is the key
The Beijing-Tianjin-Hebei region generally chooses to plant in early spring in April, and can also be planted in a small arch shed. This can advance the sowing date by more than 20 days, but the cultivation temperature of the arch shed cannot be too high, and should be controlled at 15-20 °C.
Spring coriander must not be seedlings, in the cultivation management to promote growth, dilute small water, about 20 weeks after the emergence of seedlings combined with watering to apply urea 20 kg, 10 days after the application of urea 40 kg, promote the growth of coriander plants . If the seedling grows weak, it can be sprayed with potassium dihydrogen phosphate or other foliar fertilizer.
Spring coriander should be harvested in time, otherwise it is easy to convulsion, usually harvested 35-40 days after emergence. At this time, the coriander is relatively tender, the plant height is about 35cm, the taste is good, and the aroma is rich.
The above is the cause and precautions of coriander twitching. Farmers who plant coriander in spring pay attention to the above points, and control coriander convulsions, high yield and high volume is not a problem.
