Hedgehog is a herb that is inherently toxic and poses a risk when the body is touched. At the same time, the hedgehog is very destructive. Let's take a look at the hazards and prevention measures of the hedgehog.
Breeding power is a poisonous plant that needs to spread. Normal plants can produce 20 to 30 inflorescences, each flower can open 10 to 20 flowers, 55B90 seeds can be produced in each berry, and plants can produce 1 to 20,000 grains. Seeds are spread by wind, water or hedgehogs into animal skins and human clothes, and have a strong reproductive capacity.
Excretion of crops poses a crushing hazard to crops. This unwelcome weed is almost everywhere, and wherever it goes, it generally leads to ridiculous land.
Toxic burrs can harm livestock. The plant also produces a solanine that is toxic to live animals. Symptoms of poisoning are difficulty breathing, weakness and tremors. Livestock that died from the poisoning of the fruit may also exhibit only one symptom: too much water.
It is also considered to be a “disgusting weed†in front of barns and corrals. Its fruit has a destructive effect on the production of sheep wool, and is also harmful to farmland and mountains; stems are burr-like and harmful to livestock.
Invasive In September 2011, researchers discovered the invasive alien species, Hokkaido, in the cities of Hohhot, Baotou, Wulanchabu, Xilin Gol, Chifeng, etc. in Inner Mongolia Autonomous Region. This plant not only grows on the side of the road, in the river beach, or in the grasslands. And even spread around the city. This alien invasive species is a serious threat to the ecological environment of Inner Mongolia, and livestock will be poisoned or even killed by eating.
In the growing season or heading flowering stage, the potential growing place is checked, and the morphological characteristics of the plant are used for identification, the type is determined, and the mixed condition and the mixing rate are recorded. Sampling inspection of seeds for import and export and domestic transportation. Seeds are not less than 1 kg per sample and are tested for seeds with the quarantine weed.
Control chemical control: 2,4-D can be used to control the hedgehog. When the seedling stage of the locust, the dragonfly is more sensitive to 2,4-D, but it has great resistance to 2,4-D after flowering. When 2,4-D and dicamba are used together, the effect is better than using it alone. However, 2,4-D is prone to phytotoxicity, and 30% 2 methyl 4-chloro-grass-frozen agent can be used to control the spray of 125 grams per acre before planting, and the effect is better.
Mechanical control: Disperse the plants of the Solanum nigrum L. by continuous, tight weeding or using taro before flowering to prevent the production of seeds. The way to deal with the hedgehog is to remove it and burn it for deep burial.
Precautions when eradicating the hedgehog dragon's arachnid: Take protective measures, remove the personnel to do their own protection, put on the long trousers, do not directly touch the hedgehog plant with the hand, if it is accidentally stabbed, it should be timely Apply anti-inflammatory drugs, if the symptoms can not be alleviated, seek medical advice.
Biological control: The survival space of the hedgehog dragon's sunflower is occupied by planting local dominant forage species such as Sha Dawang and Alfalfa.
