Description

Technical Field

[0001] The invention belongs to the technical field of fertilization, and in particular relates to a device and method for fertilizing sloping farmland. Background Art

[0002] The topographic complexity of sloping farmland significantly increases the difficulty and complexity of agricultural production activities. Due to the effect of gravity, water flows faster on the slope, resulting in a prominent "water runaway" problem, making it difficult to effectively retain water in the soil, causing large fluctuations in soil moisture content, and making it difficult to meet the stable moisture environment required for crop growth. This not only affects the normal physiological functions and growth and development of crops, but also increases the risk of soil drought and crop withering. At the same time, the "fertilizer runaway" phenomenon is equally serious. Fertilizers are rapidly lost under the combined effects of rainwater erosion and slope runoff, making it difficult to maintain soil fertility and difficult for crop roots to effectively absorb nutrients, further exacerbating soil impoverishment and rising agricultural production costs.

[0003] What is even more difficult is that the terrain restrictions of sloping farmland pose a severe challenge to mechanized operations. Modern agricultural mechanized equipment is usually designed based on plain operating conditions, and it is difficult to operate efficiently and accurately in the complex terrain of sloping farmland. Agricultural machinery is difficult to drive on steep slopes due to stability issues. This forces farmers to rely on traditional manual labor methods on sloping farmland, which is not only inefficient but also extremely labor-intensive. Taking the traditional fertilization method of sloping farmland as an example, farmers need to carry fertilizers on rugged slopes, which is cumbersome and inefficient. In order to achieve deep fertilization, farmers also need to cover the soil manually. In this process, they frequently bend over and stand up to carry fertilizers, which can easily cause physical fatigue and injury. If fertilizers are applied directly to the roots of crops during topdressing, in rainy weather, due to the lack of effective fixing and protection measures, fertilizers are easily washed away by rainwater, which not only fails to provide a continuous and stable nutrient supply for crops, but also aggravates fertilizer loss and waste, pollutes the soil and water environment, and seriously affects crop growth needs and yield quality. If soil is covered after fertilization, the labor intensity is greatly increased.

[0004] In summary, the current status of agricultural production on sloping farmland faces many problems and challenges that need to be solved. Traditional agricultural production methods can no longer meet the urgent needs of efficient and sustainable development of modern mountain agriculture. Therefore, exploring and innovating more scientific, reasonable and efficient sloping farmland agricultural production technologies and management models has become the key to improving the production efficiency and ecological benefits of sloping farmland, ensuring the stable development of mountain agriculture and farmers' economic benefits. This is not only an innovation and upgrade of traditional agricultural production methods, but also a strong guarantee for the ecological security and sustainable development of mountain agriculture.
