Farmers who grow carrots know that carrots are a crop with high yield and good planting efficiency. Because of the high content of vitamins and other nutrients, they also have the reputation of “small ginsengâ€, which many people like to eat. Nowadays, there are many farmers who grow carrots. If you want carrots to be productive, how to plant and manage them? Let's take a look at it together with Xiaobian.
1, fine land preparation
Carrots are meat-rooted vegetables that prefer deep and loose soil. The whole land should be deeply cultivated and the depth should be no less than 30 cm. In order to achieve intensive cultivation, the soil is finely divided, the ground is smooth, and the sensation is good. It is best to form a kneading surface of 2 to 2.5 meters wide to facilitate irrigation and drainage.
2, apply the base fertilizer
In order to prevent the problem of burning of organic fertilizer, before fertilization, it should be fully decomposed, chopped, combined with land preparation, 2500-3000 kg of organic fertilizer per mu, and 50-80 kg of ternary compound fertilizer.
3. Prevention and control of underground pests
In order to control underground pests, an appropriate amount of pesticides can be incorporated into the organic fertilizer, which has a good effect on the preservation seedlings.
4, seed treatment
The bristles on the dried seeds are first removed to facilitate the adhesion of the seeds to the soil. Seeds were placed in 40 ° C hot water for 30 minutes before sowing, then add cold water to reduce the water temperature to 20 ° C ~ 25 ° C, soak for 24 hours, until the seeds fully absorb water and then remove and germination. The suitable temperature for germination is 20 ° C ~ 25 ° C, when more than half of the seeds exposed small buds and timely sowing. Tests have shown that the seeds can be sown after treatment, and the seedlings can be emerged for 2 to 5 days early, and the emergence rate is also greatly improved.
5, chemical weeding
The timely application of the pre-emergence herbicide after sowing the soil not only eliminates the large amount of labor for manual weeding, but also the effect of weeding is relatively good. Herbicides such as dichlorfen, which is safe for carrots and have good herbicidal effects, can be used. 100-150 ml of herbicide emulsifiable concentrate per acre, 60-80 kg of water, evenly sprayed on the ground, and the effect of controlling weeds is over 95%.
6, cover grass seedlings
After spraying the herbicide, evenly cover a layer of short straw with a thickness of 2 to 3 cm on the kneading surface to prevent the soil from stagnation caused by heavy rain, and to protect the seedlings from sunburn and moisture so as not to cause the seeds to fall dry. Good results.

Ankle joint injury is one of the most common sports injuries. Ankle joint injuries are more common in sports such as running, jumping or changing direction. Ankle torsion exceeds the range of motion of the individual's joint, excessive stretching and tearing of the ligaments around the ankle joint, as well as injury of the extensor digitorum muscle belly and tendon. Tendon and abdomen; The joint between tendon and bone tissue is the most vulnerable part of injury. Foot and ankle are complex mechanisms. There are many foot-attachment joints, many of which are inching joints. The weak link of foot and ankle joint is the main part of sports injury.
If the muscles, tendons and ligaments around the ankle joint have not received enough training and are in a weak state, there is a risk of injury. For example, the muscles of the lower leg may be stronger than the overall muscles of the lower leg, which may lead to the imbalance of muscle strength. Or the Achilles tendon is too tight and the front muscles are too flexible, which leads to an imbalance of flexibility. The second is the lack of warm-up and muscle stretching activities. The support belt can provide additional support and stability for weak ankle joints and injured ankle joints.
