Spot sowing device for crop breeding and cultivation precision tests

Abstract

The present invention discloses a spot sowing device for crop breeding and cultivation precision tests. The spot sowing device comprises a frame and a container for placing seeds, wherein a plurality of steel pipes are uniformly distributed on the bottom portion of the frame, each steel pipe is provided with a steel bar capable of inserting into the steel pipe, the steel bar performs penetrating movement in the steel pipe, all steel bars are integrally connected through a horizontal pipe, the horizontal pipe is connected to a rod member with a length of larger than the length of the frame through a bending plate, the rod member slides up and down in the middle of the frame so as to drive the steel bar to move up and down in the steel pipe, the side surface of the steel pipe is provided with an inclined pipe, the inclined pipe is connected to a pipeline, the pipelines are connected to seed outlets on the bottom portion of the container, the container is arranged above the frame, and the bottom portion of the container is provided with a seed discharging device. With the spot sowing device of the present invention, the basic uniformity of the plant spacing, the row spacing and the depth of the crop seed sowing can be ensured, the single seed sowing can be ensured, especially drought-resistant sowing can be ensured, and the spot sowing device has characteristics of simple structure, easy operation, and high efficiency.

Description

technical field [0001] The invention relates to a sowing device, in particular to a sowing device used for crop breeding and cultivation precision experiments, and is especially suitable for precise experiment sowing of wheat breeding, wheat cultivation and planting of other similar crops. Background technique [0002] At present, there are mainly two methods of sowing in wheat breeding and wheat cultivation and related experiments: one is manual operation, that is, after digging ditches with a hoe, sowing on demand, and then covering the soil, this method is flexible and flexible, but it is labor-intensive It is time-consuming and complicated, and it is difficult to ensure the quality of sowing. Another way is to use Austrian seeders. This method is more effective, but it cannot sow several varieties at the same time. seed sowing, and the cost of machinery is expensive, and ordinary units cannot afford it. Contents of the invention [0003] In order to solve the sowing q...
