Recently, when the reporter interviewed in Datian Township, Shouguang City, he learned that there was a vegetable farmer planting wormwood in the village.
The open-air planting of Artemisia selengensis has good ventilation and light transmission, but how to overcome plant lodging, pests and damage is the key to ensure its yield and quality. Judging from the emergence of Artemisia halodendron, open planting is more difficult. Therefore, the reporter reminded the intentional farmers must be careful.
According to an experienced vegetable farmer, the difficulty of open-grown Artemisia halodendron is mainly reflected in the following three aspects:
First, it is hard to prevent dead trees. Because there is a lot of rain in the summer, garland chrysanthemums are used as vegetables for leafy vegetables. If water accumulates for a long period of time, it is very easy to cause dead trees. And it also easily leads to rotten leaf phenomenon.
The second is that plants are susceptible to lodging and lodging. After the seedlings of Artemisia halodendron emerge, they need to go through 2-3 seedlings, because the leaves are liable to fall down and lose their commodity value after they are immersed in water. Once they fall down, they will inevitably lead to a decrease in yield.
The third is more pests and diseases. Because it is planted in the open air, there are no protective measures. Summer is the outbreak of many kinds of insect pests. It is often an outbreak and it is a wave of waves. Not only does the number of sprays increase, but because of the high temperature, the leaves are easily produced. Phytotoxicity.
To sum up, the reporter reminded farmers in the open air planting of garland chrysanthemum to be cautious in the summer, so the planting time of garland chrysanthemum can be appropriately premised, and the growth period of garland chrysanthemum should be arranged in the delivery period of spring and summer with less occurrence of pests and less rain; During the period, the reporter suggested that the vegetable growers are still more suitable for planting in the shed.
Due to people's concerns about health, plant products from natural sources have also received widespread attention. Natural plant tea cuts are products made by direct shearing, crushing, and other physical processing of pure plants. The product retains all the original characteristics of the plant, and the properties of the product are better packaged and can be easily transported to different places.
At the same time, the active ingredients of the product are not damaged. It is widely used in functional tea and other fields. Common products are: astragalus cut, burdock cut,etc.
