[0002] In the process of chestnut tree planting, after the fruit is harvested in autumn, the temperature is relatively high and the fertilizer is easy to decompose, so it is most effective to apply fertilizer. Topdressing is mainly quick-acting nitrogen fertilizer, combined with phosphorus and potassium fertilizers. In spring, 0.3-0.5kg of urea can be applied per plant, and 2 kg of urea can be applied to each tree during the peak fruit-bearing period. In summer, topdressing is carried out from late July to mid-August. At this time, applying quick-acting nitrogen fertilizer and phosphorus fertilizer can promote the increase of fruit grains and the fullness of fruit flesh. At present, in the process of fertilizing chestnut trees, a shovel in the fertilizer applicator is often used to dig a small hole in the ground under the chestnut tree, and fertilizer is applied to the dug small hole.

[0003] However, the shovel handle of the WY-108 fertilizer applicator is fixed in size and cannot be telescoped to adjust the length. The length cannot be adjusted according to the height of the fruit farmers, which requires tall fruit farmers to bend over to operate the pointed shovel. As we all know, if fruit farmers bend over for a long time, the muscles and ligaments around the waist will be damaged, which will eventually cause inflammation and lumbar muscle strain, and may cause symptoms such as back soreness and back pain.

After being relatively clamped, the rivet 103 can be embedded in the positioning hole 104 in the cylinder 102. After the two positioning holes 104 are connected to the two positioning holes 207, the two ends of the rivet 103 are fixedly installed in the two positioning holes 104 and the two positioning holes 207, respectively. Two limit blocks 209 are fixedly installed in the semi-cylinder 208. The two limit blocks 209 are respectively arranged on both sides of the disc plate 205, and are mainly used to limit the rotation range of the disc plate 205.

[0025] Two circular holes 206 corresponding to each other are arranged on the semi-cylinder 1 201 and the semi-cylinder 2 208. The disc plate 205 is disc-shaped as a whole, and the inner diameters of the semi-cylinder 1 201 and the semi-cylinder 2 208 are the same as the outer diameter of the disc plate 205.
