Fertilizing device with mulching film breaking function

Abstract

The invention relates to a farm tool, in particular to a fertilizing device with a mulching film breaking function. The fertilizing device comprises blades, an inner tube and four cross-shaped blades;a lifting and pressing handle is held with the hands, downward force is applied, a part of each mulching film is cut into a cross-shaped opening, and the blades can push the four triangular mulchingfilms to the positions far away from the center of a film mulching opening by forward or reverse rotation, so that tearing of the mulching films during downward insertion of an insertion rod is avoided; after fertilization, the blades are lifted up, and the four triangular mulching films extend towards the center of the film mulching opening; soil falls into a pit formed by downward insertion of the insertion rod through the inner pipe; meanwhile, the falling soil covers the four triangular mulching films and is pressed into the pit formed by downward insertion of the rod; openings of the mulching films form a press sealing state, and film mulching still has good heat preservation and soil moisture increasing effects; after fertilization, the press sealing state is formed on the openings of the mulching films, so that film mulching still has good heat preservation and soil moisture increasing effects; and moreover, scissors are prevented from hurting the hands due to the fact that thescissors are not used for cutting the mulching films manually.

Description

technical field [0001] The invention relates to an agricultural tool, in particular to a fertilizing device with the function of breaking the film. Background technique [0002] Watermelon planting is often covered with plastic film, which has a good effect on increasing soil temperature and moisture retention, thus making watermelon ripen early and increase production. [0003] Watermelon seedlings need to be fertilized at the seedling stage. The existing process of farmers fertilizing film-covered watermelon seedlings is as follows: first cut a hole in the film with scissors, and then dig a pit with a shovel or pickaxe through the hole in the film. buried in the pit. [0004] The inventors of the present application have found that the above-mentioned technology has at least the following technical problems: [0005] First, the holes in the film prevent the covering from increasing the temperature and moisture retention of the soil; second, when the film is cut manually,...
