Pre-separating seedling plate

Abstract

The invention relates to a pre-partition seedling tray used for raising rice seedling, belonging to the technical field of agricultural seedling raising implements. A tray bottom of a tray body of the seedling tray is separated into a rectangular tray lattice array by interlaced long ribs, the interior of the tray lattice is divided into matts by four short ribs which are distributed in a cross shape, the four short ribs are not connected with each other and also are not connected with the long ribs at the periphery of the tray lattice, the height of the long ribs is higher than that of the four short ribs, and a water permeable hole is arranged on the part of the tray bottom at the center of the cross shape corresponding to the four short ribs. When seedling is taken, seedling blocks with uniform size and regular shape are easy to be formed in virtue of seedling needles, thus satisfying the requirements of mechanized plantation of super rice. Furthermore, the long ribs and the short ribs are reasonably arranged, so as to not only solve the problem of accurately seedling taking, but also form a water homogenizing structure which can keep the moisture content in each tray lattice at an ideal state, thus being beneficial to avoiding the root rot of rice seedling and water and fertilizer loss, and guaranteeing the normal growth of rice seedling.

Description

technical field [0001] The invention relates to a flat-bottomed seedling tray for seedling raising, in particular to a pre-separated seedling tray, which belongs to the technical field of agricultural seedling raising appliances. Background technique [0002] According to the applicant's understanding, there are two kinds of hard disks and floppy disks for seedling raising at present. These seedling trays are basically flat-bottomed structures. After the seedlings are raised, the entire tray of seedlings is not pre-separated, so when cutting the seedlings, it is necessary to rely on the tearing of the seedling needles. As a result, the shape of the cut seedlings changes greatly. It is difficult to meet the precision requirements of super rice mechanized planting. [0003] In addition, another problem with flat-bottomed seedling trays is that it is difficult to ensure that the bottom of the tray is in the same level state, so it is easy to form water accumulation in the slow...

Problems solved by technology

These seedling trays are basically flat-bottomed structures. After the seedlings are raised, the entire tray of seedlings is not pre-separated, so when cutting the seedlings, it is necessary to rely on the tearing of the seedling needles. As a result, the shape of the cut seedlings changes greatly. It is difficult to meet the precision requirements of super rice mechanized planting

[0003] In addition, another problem with the flat-bottomed seedling tray is that it is difficult to ensure that the bottom of the tray is in the same level state, so it is easy to form water accumulation in the slow-draining area, resulting in rotten roots of the seedlings, and causing fertilizer and water loss in the fast-draining area, affecting the healthy growth of the seedlings
