Successful application of LYJ multi-function top dressing gun in Hohhot area, valuable experience
The LYJ multi-functional top-dressing fertilizer gun is a newly developed product by Zhangye Gansu Multi-Functional Fertilizer Gun Co., Ltd. This innovative farm equipment has been granted both national invention and utility model patents. It combines multiple functions such as deep fertilizer application, pest and disease prevention, water injection, drought resistance, fertilizer efficiency, insect control, and labor-saving. The device is designed to enhance agricultural productivity while addressing the challenges of water scarcity and environmental stress.
To tackle the issue of climate-related droughts in our city, especially during spring and summer when water shortages and seedling protection are critical in ecological projects, the city introduced the LYJ multi-functional fertilizer gun twice, in 1998 and 2001. Thousands of units were deployed, and the technology was widely promoted throughout the region. The results have been impressive, playing a vital role in both agriculture and ecological development. It has received high recognition from local officials and positive feedback from farmers.
The application of this device in the city has shown three main benefits:
First, it effectively addresses summer drought conditions by creating water points for plants. For example, when used on corn, it saves up to 80% of water, reduces fertilizer use by 30%, and cuts labor costs by two provincial workers per unit area.
Second, it helps manage drought during summer and autumn by efficiently using water. On corn fields, it uses only 1.5 square meters of water per acre and reduces labor by four people. This method delays crop dehydration by 8–10 days. Compared to traditional sprinkler irrigation, it saves 90% of water, 40% of fertilizer, and increases yield by 13%.
Third, it plays a crucial role in ecological construction by protecting young seedlings from drought. In 2001, when severe drought struck, the device helped save 60% of the water used for Pinus tabulaeformis (Chinese pine) seedlings. By dividing water supply into two applications in spring and four times in summer and autumn, the seedlings remained healthy and continued to grow even under harsh conditions.
Overall, the LYJ multi-functional fertilizer gun has proven to be an essential tool for sustainable agriculture and environmental protection, offering practical solutions to long-standing challenges faced by farmers and ecologists alike.
