The main producing area of ​​wheat in China is in the north. Because the climatic conditions in the north are not suitable for planting rice, and the adaptability and viability of wheat to the environment are relatively strong, wheat has become the staple food of the people in the north. Northerners are generally whiter than southerners. That is because they eat pasta for a long time. Nowadays, pasta is also very popular in the south. Therefore, the cultivation of wheat has been vigorously promoted. The following content is about China’s second. Let's take a look at the planting time and planting methods of large grain crops.
Planting time
Wheat is divided into spring wheat and winter wheat, so it is doomed that the planting time of wheat is different. In North China, it is usually planted around November in winter, while in Northeast China, it is planted in spring and April. Because there is a thick layer of snow in the northeastern region of China, the temperature is very low and it is not suitable for the growth of wheat. Therefore, it is generally not planted in winter. Secondly, the climate in North China is relatively stable throughout the year. It can be used for many rounds, so just wait for other crops to be planted in winter after harvesting in the fall to prevent the land from being abandoned.
Planting method
1, choose the soil preparation
Nowadays, the varieties of wheat are not as single as before, so we can screen them. We first consider the local Qihoo and the local soil and other conditions to choose the most suitable variety. For example, in areas with less rain, choose drought-resistant, In areas with poor soils, choose adaptability, choose cold-resistant areas in colder weather, and choose strong disease-resistance in rainy areas, so choose according to specific conditions.
In order to ensure the growth and yield of wheat, the land should be at least 30 cm deep into the soil layer, and the soil should be thinned, the field should be filled, then four thousand kilograms of farmyard manure, and then the land Turn over once, mix the fertilizer well, then start a small ditch every one meter to one meter five, prepare for drainage and irrigation, and finally wait for planting.
2, reasonable sowing
Before sowing, we usually need to carry out germination treatment and seed dressing. First, we soak the wheat seeds in water for two days, then remove them, put them in the medicine and mix them evenly. After 20 minutes, rinse them with water and then use the seeds. The cotton cloth is wrapped up and hung up on the surface of the water. After about three days, the seeds will germinate and then you can sow.
There are several ways to sow. The most common way we use is to broadcast, that is, to make a small ditch at a distance of thirty centimeters per line in a good place, then spread the seeds evenly in the ditch, and then cover it with dirt. Kind.
It is more common in rural areas to spread, which is relatively simple, as long as the planting is evenly spread over the field and then planted. Finally, a more detailed method of planting is to make a 30 cm interval between each row and each plant. Small holes, then sprinkle three to five seeds in each small hole, then cover up and wait for emergence.
3. Field management
When a thin layer of green is grown in the wheat field, we can carry out the first fertilization and watering. At this time, the watering can be carried out by watering. The fertilization is mainly to use urea to promote seedling, and it can be directly spread. It can also ease watering in the water.
The second fertilization is also the time when the wheat seedlings are split. At this time, the watering is sprayed, so that the wheat seedlings will not break. At this time, we still use urea, but this time we need to add 20 kg of phosphate fertilizer and 30 kg of compound. fat. Finally, when the wheat seedlings are heading, this is the key moment to determine the wheat yield. We mainly apply phosphate fertilizer, potassium fertilizer, and boron fertilizer, and finally spray some non-toxic chemicals that are full of wheat grains.
4, disease prevention
The most common disease before wheat planting is wheat lodging. It usually occurs in the period of maturity after wheat heading. If there is a large area lodging at this time, the yield and quality of wheat are not good, so we usually manage it in daily life. It is necessary to remove the water in time, and use the fertilizer and the amount of the right, as well as the planting density. If one or two seedlings appear in the field, it is necessary to carry out chemical control. The specific medicine can be consulted.

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.
