Description

Fertilizer device for planting fruit tree seedlings

Technical Field

The utility model relates to the technical field of seedling fertilization, in particular to a fertilization device for planting fruit tree seedlings.

Background technique

Fruit tree seedling planting refers to the process of planting and cultivating fruit tree seedlings. When planting fruit trees, it usually starts with seedlings. Through planting, cultivating and managing seedlings, they grow into healthy fruit trees. This technology covers key steps such as selecting a suitable geographical environment, applying fertilizers reasonably, preventing and controlling pests and diseases, and pruning and planting at the right time. The goal of fruit tree seedling planting is to cultivate high-quality fruit trees with good growth, lush leaves, strong resistance to pests and diseases, high fruit quality and stable yield. Fruit tree seedling planting is a very important link in the fruit tree industry and has a direct impact on the growth and yield of fruit trees. Among them, fertilization is the process of providing plants with essential nutrients, such as dissolving water-soluble fertilizers in water and then adding fertilizers to the plant's growth medium. Water-soluble fertilizers, also known as water-soluble fertilizers, are fertilizers that can be dissolved in water for plant roots to absorb. It usually exists in the form of powder, granules or crystals. By dissolving it in an appropriate amount of water to form a fertilizer solution, it is then applied to plants by irrigation or spraying to provide the nutrients required by plants to promote plant growth, development and yield.

At present, the fertilization device used for planting fruit tree seedlings mainly fertilizes by spraying. The process is to dissolve water-soluble fertilizer in water and fertilize the seedlings by spraying. However, the existing fertilization device dissolves the water-soluble fertilizer in water mainly based on personal experience to control the weight and dissolves it with water in a certain proportion. It is easy to have excessive or insufficient fertilizer, resulting in nutritional imbalance and waste of resources. Secondly, too high or too low fertilizer concentration will have adverse effects on plants. Since the fertilization device has only one dissolving bin, it is impossible to switch the fertilizer to the appropriate concentration for fertilization according to the size of the fruit tree seedlings.

Therefore, a fertilizing device for planting fruit tree seedlings is proposed to solve the above problems.

At this time, the T-shaped pull rod 73 is held and pushed backward or pulled forward to discharge the water-soluble fertilizer into the rear or front L-shaped box 75, and then the water-soluble fertilizer falls into the corresponding cavity to accurately allocate the water-soluble fertilizer according to a certain proportion;

The second step, after the preparation is completed, drive the stirring motor 61 to drive the rear stirring shaft 64 to be coaxially connected. Since the gears 62 on the two stirring shafts 64 are connected through the belt 63, the two stirring shafts 64 rotate synchronously. Since a large number of stirring blades 65 are evenly installed on the stirring shaft 64, the stirring blades 65 will be driven to rotate during the rotation of the stirring shaft 64, thereby driving the clean water and water-soluble fertilizer to stir and accelerate the dissolution. After the dissolution is completed, turn off the stirring motor 61, and then open the valve 8 of the fertilizer of the corresponding concentration according to the size of the fruit tree seedlings, and close the other valve 8, so that the fertilizer in the corresponding cavity flows into the water inlet of the water pump 101 through the connecting pipe 9 and the feed pipe 102. At this time, drive the water pump 101 to pump the fertilizer in the cavity and transport it to the hose 104, and finally spray it out from the spray gun 105. You only need to hold the spray gun 105 and aim it at the trunk of the seedling to complete the spraying and fertilization.
