Drought significantly affects agricultural productivity. Due to the lack of adequate irrigation infrastructure and limited drought resistance in our country, it is essential to adopt emergency irrigation technologies and equipment that can help mitigate the impact of drought. Among these, drought-resistant and water-saving seeders are particularly effective. These machines combine seeding and irrigation functions, enabling farmers to plant crops even when soil moisture is low. They perform both sowing and watering simultaneously, making them highly efficient and suitable for areas with limited water resources.
One such technology is the unit seeder. This machine typically includes a frame, front shovel, opener, seeder, and soil cover. It is usually attached to the back of a water tanker, such as a tractor or animal-drawn vehicle, allowing it to carry out multiple tasks—ditching, irrigation, sowing, fertilizing, and soil covering—in a single operation. Its daily operating efficiency is around 0.33 hectares. With features like water conservation, labor reduction, strong adaptability, and ease of use, it is ideal for broadcasting crops like corn, soybeans, and sorghum on demand.
Another model is the water-and-hard seeder. This device integrates a seeder and an irrigation system, allowing sowing and watering to be done at the same time. It mounts a water tank directly onto a tractor or seeder, with a water pipe positioned behind the seeding tube. After digging a furrow and sowing the seeds, a small amount of soil is placed over them, followed by a controlled amount of water. Finally, the soil is fully covered, completing both seeding and watering. The machine also has a soil covering mechanism on the back of the opener, ensuring proper seed depth and better access to deep soil moisture. The surface furrows created help collect rainwater, which is beneficial for seedling growth, especially in semi-arid regions.
The third type is the drought-resistant irrigation seeder. This machine is equipped with a complete irrigation system, including water tanks, pipes, and valves, mounted on a tractor. It works in conjunction with drills or on-demand seeding machines. A single water box can cover up to 0.033 hectares. The irrigation system is positioned in front of the seed tube, ensuring that seeds are planted in moist soil and then covered properly, meeting the technical requirements of modern agriculture.
These technologies not only improve water-use efficiency but also enhance crop resilience during dry periods, making them vital tools for sustainable farming in drought-prone areas.
Whitening Raw Materials
Multiple factors must be considered when choosing whitening ingredients to ensure that the ideal whitening effect is achieved.
First of all, in terms of efficacy, raw materials with obvious whitening effects should be selected. For example, vitamin C can inhibit the generation of melanin, arbutin can reduce the deposition of melanin, glutathione, Azelaic Acid, Coenzyme Q10, MCC, Tranexamic Acid, and ferulic acid have antioxidant effects. These ingredients are effective in brightening the skin and lightening spots.
Second, security is Paramount. Choose non-irritating to skin, and non-toxic raw materials, to avoid excessive skin stimulation due to improper use, causing allergies and other problems. In this way, we can ensure that while pursuing whitening, it will not cause harm to the skin.
In addition, stability is also a key concern. The selection of stable raw materials can avoid the loss of whitening effect during the production process or storage to ensure the quality and durability of the product.
In addition, air permeability can not be ignored. The selection of good breathable raw materials can make it better penetrate the skin surface and play a whitening effect. Different skin types and needs may require different combinations of raw materials, so careful consideration and selection need to be made according to the specific situation to achieve the best whitening results.
In short, only on the basis of fully considering factors such as efficacy, safety, stability, and breathability, combined with different skin types and needs, a reasonable selection of whitening raw materials can truly achieve effective whitening and make the skin glow healthy and beautiful.
