Description

Technical Field

[0001] The utility model relates to the technical field of agricultural fertilization equipment, in particular to a high-quality wheat precision fertilization device. Background Art

[0002] Wheat topdressing refers to the timely application of appropriate amounts of fertilizer during the wheat growing season, tailored to its growth and development needs. This ensures adequate nutrients, promotes healthy growth, and improves yield and quality. Topdressing is typically performed after the wheat seedlings have emerged. Care should be taken to ensure that fertilizer is applied within the intervening fields between the wheat plants, ensuring precise fertilization. The timing of topdressing is crucial and is typically determined based on the wheat's growth stage and condition. Key topdressing periods include: Tillering Period: 20-30 days after sowing, when wheat begins to tiller. Purpose: Promote tillering, increase the number of effective tillers, and lay the foundation for later growth. Fertilizer: Primarily nitrogen fertilizer, with urea or ammonium nitrate being suitable. Jointing Period: 60-70 days after sowing, at the early stages of wheat jointing. Purpose: Promote stem growth, increase stem thickness, and prevent lodging. Fertilizer: Primarily nitrogen fertilizer, supplemented with appropriate amounts of phosphorus and potassium fertilizers, and compound fertilizer or urea can be used. Heading Period: During the wheat heading period, generally 90-100 days after sowing. Purpose: Promote ear development, increase grain number per ear, and increase thousand-grain weight. Fertilizer: Primarily phosphorus and potassium fertilizers, supplemented with appropriate amounts of nitrogen fertilizers, such as diammonium phosphate or potassium sulfate. After topdressing, regularly observe wheat growth, evaluate fertilization results, and make adjustments if necessary. Scientific and rational topdressing management can effectively improve wheat yield and quality while minimizing environmental impact and achieving sustainable agricultural development.

[0003] A precision wheat fertilization device is an agricultural device that precisely controls the amount and location of fertilizer applied. Using this device allows for scientific fertilization, improves agricultural production efficiency, and promotes sustainable development. Existing wheat topdressing equipment cannot effectively deliver fertilizer to a depth of 4-5 cm below the soil, resulting in fertilizer waste and impacting wheat growth. Traditional fertilizer plowshares create wide and deep furrows, which can damage the roots of established wheat and affect its growth.

[0004] Therefore, there is an urgent need to design a high-quality wheat precision fertilization device to solve the problem that the existing wheat topdressing fertilization equipment cannot effectively control the depth and width of the furrow, affecting the fertilization effect and wheat growth.
