Description

Technical Field

[0001] The invention belongs to the technical field of crop planting, and particularly relates to a high-survival breeding sand bed for high-oleic rapeseed. Background Art

[0002] High oleic rapeseed breeding means that after the high oleic rapeseed seeds have been peeled, they are immediately placed in a sand bed for storage, with a layer of fine sand and a layer of seeds. The bottom sand is 20 cm. After the last layer of seeds is laid, the top layer is laid a little thicker. The temperature and humidity of the seeds are checked frequently to prevent them from being too dry or too wet, and to prevent them from being too hot. After the high oleic rapeseed has been stored in the sand, if the seed embryos are white, they can be put into the breeding stage in spring or early spring, and the white seeds are sieved out through a sieve;

[0003] Chinese utility model patent: Application number CN202121669739.3, publication number CN215872980U discloses a seedling sand bed with automatic temperature control function, including a bed body, a partition is horizontally installed inside the bed body, the upper surface of the partition is paved with seedling sand, a temperature sensor is installed on the upper surface of the partition and inside the seedling sand, a heating plate is installed on the bottom inner wall of the bed body, a controller is installed on the left side wall of the bed body, a plurality of evenly distributed heat pipes are installed on the upper surface of the partition, the heat pipes are inserted into the interior of the seedling sand, and a spray mechanism is detachably provided on the top of the bed body. The utility model has the functions of automatic temperature control and uniform watering, which improves the quality of seedling cultivation;

[0004] During actual use, the seedling sand bed is unable to specifically screen the whitened seeds. When the seeds in the middle or bottom layer turn white, the seedling sand bed needs to remove the seeds in the upper layer before taking out the whitened seeds in the middle and bottom layers. This will cause the seeds in the upper layer to be moved and damaged, and the survival rate will be greatly reduced. At the same time, during the laying process of the existing breeding sand bed, the distance between seeds is controlled by manual observation, which will cause the distance between seeds to be too narrow or too wide, affecting the survival rate of the seeds. For this reason, we have designed a high-survival breeding sand bed for high-oleic rapeseed to solve the above problems. Summary of the invention
