[0023] The beneficial effects of the present invention are:

[0024] Firstly, the present invention can make the soil inside the breeding trough move upward for a distance after the soil is compacted by setting the fixing component and the loosening component, and can also make the clamped peach rootstock have a tendency to move upward relative to the soil during the movement, so as to achieve loosening between the peach rootstock and the soil, and further can loosen the soil of the breeding peach rootstock, thereby improving the effect of subsequent peach rootstock breeding;

[0025] Secondly, the present invention, through the setting of the sealing component, the fixing component and the loosening component, can selectively seal the bottom of the breeding trough, ensuring that there is an appropriate amount of moisture inside the breeding trough. When the soil needs to absorb oxygen and breathe, the blockage of the soil can be released, thereby improving the breeding effect of the equipment on peach rootstocks.
