Embodiment 1
[0032] read on figure 1 as well as figure 2 , further, the thickness of the floating seedling mother tray 1 is 3.5cm, the bottom surface diameter of the tapered through hole 11 is 0.6cm, the top surface diameter of the tapered through hole 11 is 1.6cm, and the two or more The pitch of the tapered through holes 11 is 2.2cm; the thickness of the master disc is 3.5cm, the bottom surface diameter of the tapered through holes is 0.6cm, the top surface diameter of the tapered through holes is 1.6cm, and the two The distance between the more than two tapered through holes is 2.2 cm, the thickness of the sub-disk is 6 cm, and the diameter of the two or more cylindrical through holes is 2.8 cm. ; This specification is the preferred size of the floating seedling mother tray or the mother tray, so that the amount of substrate required for cultivation under this specification and the growth of the cultivated seedlings reach an optimal ratio.
Embodiment 2
[0034] read on figure 1 as well as figure 2 , the thickness of the floating seedling raising mother tray 1 of the present embodiment is 3.2cm, the bottom surface diameter of the described tapered through hole 11 is 0.3cm, the top surface diameter of the described tapered through hole 11 is 1.5cm, and the above two cones The pitch of the through-holes 11 is 2.2cm; correspondingly, the thickness of the master disc is 3.2cm, the diameter of the bottom surface of the tapered through-hole is 0.3cm, and the diameter of the top surface of the tapered through-hole is 1.5cm. The distance between the two or more tapered through holes is 2.2 cm, the thickness of the sub-disk is 5 cm, and the diameter of the two or more cylindrical through holes is 2.7 cm.
Embodiment 3
[0036] read on figure 1 as well as figure 2 , the thickness of the floating seedling raising mother tray 1 of the present embodiment is 3.5cm, the bottom surface diameter of the described tapered through hole 11 is 0.5cm, the top surface diameter of the described tapered through hole 11 is 1.7cm, and the above two cones The pitch of the through-holes 11 is 2.2cm; correspondingly, the thickness of the master disc is 3.5cm, the diameter of the bottom surface of the tapered through-hole is 0.5cm, and the diameter of the top surface of the tapered through-hole is 1.7cm. The distance between the two or more tapered through holes is 2.2 cm, the thickness of the sub-disk is 7 cm, and the diameter of the two or more cylindrical through holes is 2.9 cm.
[0037] The present invention also provides a method for cultivating tobacco seedlings using the floating seedling raising device with good seedling quality, comprising the following steps:
