Successful application of LYJ multi-function top dressing gun in Hohhot area, valuable experience
The LYJ multi-functional top-dressing fertilizer gun is a cutting-edge agricultural tool developed by a company in Zhangye, Gansu Province. This innovative device has been granted both national invention and utility model patents, making it a unique solution for modern farming needs. Designed to combine multiple functions, the LYJ gun allows for deep fertilizer application directly into the root zone of plants, while also helping to prevent pests and diseases, provide water injection, enhance drought resistance, and improve crop yield. It effectively reduces labor costs and increases efficiency in farm management.
To address the issue of drought in our city, especially during dry seasons and seedling stages, the city introduced the LYJ multi-functional top-dressing gun in 1998 and again in 2001. Thousands of units were distributed, and their application was widely promoted throughout the region. The results have been impressive, with significant benefits observed in both agricultural production and ecological restoration. The device has received high recognition from local officials and positive feedback from farmers due to its practical performance.
The application effects of the LYJ gun in the city can be summarized in three main areas:
First, during summer drought periods, the device helps to create water points for crops. For example, when used on corn, it saves up to 80% of water, 30% of fertilizer, and reduces labor by two provincial workers.
Second, during summer and autumn droughts, the device significantly improves water and nutrient efficiency. Using corn as an example, it uses only 1.5 square meters of water per acre and reduces labor by four people. It can delay crop drought by 8–10 days. Compared to traditional sprinkler irrigation, it saves 90% of water, 40% of fertilizer, and increases production by 13%.
Third, in ecological construction, the LYJ gun plays a vital role in protecting seedlings during drought conditions. For instance, when applied to *Pinus tabulaeformis* seedlings, it saved 60% of water during the severe drought of 2001. It allows for two applications in spring and four in summer and autumn, ensuring seedling survival and healthy growth even under harsh conditions.
Overall, the LYJ multi-functional top-dressing fertilizer gun has proven to be an essential tool in improving agricultural productivity and environmental sustainability. Its success continues to inspire further innovation and adoption in rural communities.
