In order to strive for spring vegetables in the morning, high yield and good efficiency, it is a prerequisite for the vegetable farmers to do temperature management: the temperature in the spring keeps rising, but it is still necessary to pay attention to the invasion of cold air, and the greenhouse vegetables are well regulated by temperature and humidity. The management method of “Daily Sanfeng†can not only reduce the indoor humidity, increase the carbon dioxide content, promote photosynthesis, but also increase the yield and increase the plant resistance. The specific operation method is as follows: pull the grass for about an hour in the morning, and let the wind release for 15 to 20 minutes. At this time, the tuyere should be opened slightly, about 10 to 15 cm wide, in order to remove the accumulated moisture for a night, and at the same time to supplement the carbon dioxide content in the shed. Because the outdoor temperature in the morning shed is very low, the air vent should not be opened too much, and the air release time should not be too long, so as to avoid excessive temperature drop in the shed and slow recovery. When the temperature in the shed rises to 28 ° C ~ 30 ° C, the air outlet can be pulled out to release air. The tuyere should be gradually opened from small to large, so that the indoor temperature of the shed is controlled at about 30 °C, which is conducive to the good growth of the plant. In the afternoon, the indoor temperature will gradually decrease. At this time, the small air inlet should be gradually closed to keep the temperature at around 25 °C; when the indoor temperature is lower than 22 °C, the air outlet should be completely closed. 30 ° C ~ 25 ° C is the appropriate temperature to ensure the good growth of vegetable plants, so the greenhouse management should try to maintain this condition, giving the plant a comfortable environment. In the afternoon, about half an hour before the release, the small air outlet was released for 15 minutes. The purpose was to discharge the moisture in the shed and add some fresh air to help the vegetable plants grow at night. When the indoor temperature in the shed is about 20 °C, the grass hoe should be put down to ensure that the plant grows at night without being affected by cold. Special weather to uncover the grasshopper method: 1. The weather warms up in March and April, and the night cover should be removed as early as possible. 2, rainy weather - try to reveal the light during the day, and can not be revealed for several days. 3, even the yin and yin - can take the "cover and cover", with the return measures, and gradually transferred to normal management. Found that the wilting, can spray water emergency.

Handheld laser therapy devices, also known as low-level laser therapy (LLLT) devices or cold laser therapy devices, offer several benefits for various applications. Here are some of the key benefits:
1. Pain Relief: Laser therapy devices can provide effective pain relief by stimulating the release of endorphins, reducing inflammation, and improving blood circulation. They can be used to alleviate acute and chronic pain in conditions such as arthritis, sports injuries, back pain, and fibromyalgia.
2. Accelerated Healing: Laser therapy promotes tissue repair and regeneration by increasing cellular energy production. It helps to speed up the healing process of wounds, cuts, burns, and post-surgical incisions. It can also be used to treat skin conditions like acne, eczema, and psoriasis.
3. Non-Invasive and Non-Pharmacological: Laser therapy is a non-invasive treatment option that does not require surgery, injections, or medications. It offers a drug-free alternative for pain management, reducing the risk of side effects and drug interactions.
4. Easy to Use: Handheld laser therapy devices are portable and user-friendly. They can be used at home or on-the-go, allowing individuals to manage their pain or promote healing conveniently and independently.
5. Versatile Applications: These devices can be used for a wide range of conditions, including musculoskeletal injuries, nerve pain, joint pain, dental problems, skin disorders, and more. They are suitable for both human and veterinary use.
6. Cost-Effective: Compared to other treatment options, handheld laser therapy devices can provide cost savings in the long run. They offer a one-time investment, eliminating the need for ongoing medication or frequent visits to healthcare professionals.
7. Minimal Side Effects: Laser therapy is generally safe and well-tolerated. It has minimal side effects, such as temporary redness or warmth at the treatment site. However, it is important to follow the manufacturer's instructions and consult a healthcare professional if needed.
