Flax cultivation methods and precautions

1. Maintenance methods

1. Temperature: The temperature for maintaining it should be above 18 degrees. If it is lower than 18 degrees, the survival rate of plant cuttings will not be high. If the temperature is higher than 25 degrees, the cut of the cuttings will easily become infected and rot, so it is enough to control the maintenance temperature between 18-25 degrees.

2. Watering: It needs sufficient water to grow. You can water it by spraying twice a day to keep the soil moist for a long time. If there is drought, you need to increase the watering frequency. Winter irrigation is needed before winter, which is conducive to the plant's overwintering and regreening.

3. Fertilization: Before sowing, you need to mix base fertilizer into the soil. It is best to use organic fertilizer or low-nitrogen compound fertilizer. Control the amount of fertilization to avoid excessive fertilization, otherwise it will cause the plant to grow too tall, and in severe cases it will lead to no flowering.

4. Light: It is not resistant to strong light, so it needs proper shade. Excessive light will cause the temperature to rise and the water loss of the plant will increase, which is not conducive to the survival of the plant cuttings. After the plant cuttings take root, the light time can be gradually increased.

2. Breeding techniques

1. Reproduction: For reproduction, you can use sowing propagation. The sowing time is in spring and autumn. If sowing in spring in the northern region, the survival rate will be higher. When sowing, sprinkle the seeds into the soil mixed with base fertilizer, cover with a thin layer of soil, and water enough. Generally, the seedlings will emerge in a week.

2. Pruning: During the growth process, the flax seedlings need to be pinched, usually when the plant grows to six to ten centimeters. This is done to promote branch growth. The second pinching can be done one month after the first pinching.

3. Problem Diagnosis

1. Pests: The plants are more susceptible to flea beetle pests. If found, you can use cypermethrin emulsifiable concentrate for spraying. It should be noted that the agent needs to be diluted before use.

2. Pathology: The plant is easily infected by diseases such as anthracnose. This disease may infect the plant from the emergence to the maturity stage, but it usually occurs in the early growth stage of the plant and mainly harms the young roots and leaves of the plant. If found, it is necessary to use prochloraz emulsifiable concentrate for spraying treatment.
