Chrysanthemum chrysanthemum is a kind of vegetable, but with the discovery of its nutritional value, it is gradually used as a medicinal material. The taste of chrysanthemum is also different from other vegetables, there is a kind of spicy feeling, with spleen to stop phlegm, laxative and other effects. Chrysanthemum chrysanthemum has been planted in China for nearly a thousand years. Although the planting technology of chrysanthemum chrysanthemum is relatively perfect, it also requires us to do a good job in daily management to ensure normal growth. Let's take a look at the field management methods of chrysanthemum.

1. Control temperature

Artemisia chrysanthemum is a temperature-loving crop, and the temperature range suitable for the growth of Artemisia annua is about 18 degrees. However, chrysanthemum chrysanthemum is generally planted after the Beginning of Spring, and the temperature has not completely recovered at this time, so if you do not pay attention to control the temperature, it is easy to appear the phenomenon of late spring cold, resulting in weak seedlings or even dead seedlings. Therefore, we should cover the plastic film on the sowing surface and press the plastic film in time after sowing. Do a good job of cold prevention and heat preservation measures to promote seed germination and emergence. When the temperature gradually picks up, the plastic film is opened, but when the temperature is too high, we should also pay attention to timely cooling.

2. Weeding between seedlings

When the seedlings were unearthed, the growth of all seedlings was observed, and it was found that there were weak seedlings or dead seedlings in time. Then when the seedlings grow to about 9-11 cm, do a good job of inter-seedling work, according to different varieties to determine the distance between seedlings. It is necessary to remove the excess weeds in the field between seedlings, because the growth capacity of weeds far exceeds that of seedlings, and weeds also need a lot of nutrients and water to grow. If the weeds are not removed in time, the nutrition will snatch all the weeds and hinder the growth of the seedlings.

3. Water and fertilizer management

Water and fertilizer is an indispensable thing in the growth of Artemisia annua. Strengthening the management of water and fertilizer can improve the growth rate and resistance of Artemisia annua. When the seedlings grow, water them in time to promote the water absorption of the seedlings. The frequency and time of watering should be determined according to the growth of the seedlings. Keep the soil moist and provide sufficient water demand for seedlings. Then observe the soil fertility, the growth stage of chrysanthemum and other timely topdressing. Generally speaking, a quick-acting nitrogen fertilizer should be applied two weeks before harvest, depending on the planting area of measuring tools. When fertilizing, we should pay attention to the use of nitrogen fertilizer, do not use too much, to prevent the phenomenon of chrysanthemum growing.

4. Pest control

Pest control is a work that must be done well in the whole growing period of Artemisia annua. The harm of diseases and insect pests to Artemisia annua is not the slightest bit. In serious cases, it can lead to the extinction of Artemisia annua. The more common diseases are blight, leaf spot and so on, and insect pests are vegetable borer and aphids. Strengthen the management of the field, do a good job in the prevention of various diseases and insect pests, when interesting phenomena of diseases and insect pests are found. It is necessary to immediately detect specific diseases and insect pests, and then carry out corresponding treatment measures, the rational use of various pesticides and pesticides. However, we should pay attention to the dosage, high drug concentration will also inhibit the growth of chrysanthemum.

The above is a brief introduction to the field management of chrysanthemum sorted out by the editor. Planting chrysanthemum not only requires certain planting techniques, but also requires everyone to do a good job in field management. Several aspects mentioned by the editor must be within reasonable control. For example, watering should not be excessive, otherwise it is easy to rett roots, which is also very disadvantageous to the growth of Artemisia annua. That's all for today's introduction.
