[0002] Liquid fertilizer is a mixture of various organic elements chelated with water and then sprayed directly on the leaves or roots of plants for rapid absorption. Liquid fertilizer is the first choice for irrigation systems such as sprinkler irrigation and drip irrigation due to its quick dissolution and uniformity.

The problem solved by the present invention is that it is difficult to be applied to agricultural soil planting with high efficiency, and it is difficult to The angle and position of fertilization can be quickly adjusted according to the farmland layout and crop distribution. Fertilizer cannot be accurately delivered to the roots or leaves of crops, which will greatly cause fertilizer waste. Excessive use will increase the risk of soil and water pollution and nutrient loss. The present invention combines the above-mentioned components with each other. The equipment is conveniently moved through the mobile wheel group 111 and is suitable for agricultural soil planting and fertilization, thereby improving the operation efficiency. The flexibility of fertilization operation is significantly improved by integrating the rotating telescopic adjustment mechanism 4. The liquid fertilizer spraying mechanism 5 is controlled to be quickly adjusted according to the farmland layout and crop distribution. The combined height adjustment structure and the telescopic adjustment structure realize the precise control of the fertilization height and the flexible adjustment of the horizontal distance, so that the fertilizer can be more accurately The liquid fertilizer spraying mechanism 5 fully considers the fertilization requirements of different crops, realizes the function of directional fertilization at the roots and leaves, helps the fertilizer to directly act on the roots and leaves of crops, and meets the nutrient requirements of crops at different growth stages. Through precise fertilization, the excessive use of chemical fertilizers is reduced, which helps to reduce the risk of soil and water pollution, and conforms to the concept of sustainable development of modern agriculture. The utilization efficiency of liquid fertilizers is higher than that of traditional solid fertilizers, which reduces nutrient loss, improves the economic and environmental benefits of agricultural production, promotes the rational use of agricultural resources and the protection of the ecological environment, and has broad market application prospects and social value.
