The latest points for attention in the planting of Artemisia annua

There are a lot of people who grow this kind of vegetable, but they also encounter a lot of problems. In fact, the technical demand for planting chrysanthemum is not high, but some problems can not be solved simply. What problems do you need to pay attention to when planting? We should pay attention to these.

1. Early weeding

In the early stage, the root system of chrysanthemum chrysanthemum is not only shallow, but also easily robbed by weeds, so weeding in the early stage is one of the problems that we should pay attention to. When there are many grasses in the field, it is difficult for Artemisia annua to grow. Here either do not use herbicides before planting, or clean up after planting, there must be no more weeds around the seedlings, mainly around the seedlings.

2. Medium-term water control

In the middle of the year, Artemisia annua itself has a certain ability to protect itself, and at this time the general weeds are basically no threat to it. But this stage is a prosperous stage, and the demand for water begins to rise, so the focus at this time is to control water and consider how to meet the water source growth of Artemisia annua. At this stage, we should observe the growth of Artemisia annua after each watering, about once every 3-5 days, so as to ensure its growth.

3. Disease prevention

With the advent of the prosperous period, all kinds of diseases will naturally increase because the areas they come into contact with are getting larger. Things like downy mildew are quite common, and we need to make some targeted adjustments to prevent the disease. The source of chrysanthemum chrysanthemum disease comes from many sources of soil, so the disinfection of soil and the disinfection of chrysanthemum itself are the two key points, we can use some agents to prevent them.

4. Prevent low temperature

Low temperature is the enemy of vegetables, and chrysanthemum chrysanthemum is more difficult to resist the existence of low temperature, so we must pay attention to prevent low temperature when planting. When the chrysanthemum is below 5 ℃, it basically does not grow, and it is even dangerous. below zero, there may be a large number of deaths, so in all kinds of low temperature days, we should sit down cold prevention measures, such as some mulch film and so on, we had better use it in time to avoid loss.

These are some of the problems that need to be paid attention to when planting Artemisia annua. I hope everyone will pay attention to it. Vegetables themselves are relatively fragile, want to high-yield basically depends on everyone to do a good job of management.
