Seedling cultivation device for cotton breeding

Abstract

The invention discloses a seedling cultivation device for cotton breeding, and relates to the field of cotton breeding. The seedling cultivation device for cotton breeding comprises two first fixing sleeves, first supporting shafts are movably connected to the inner walls of the two first fixing sleeves in an inserted mode, a first seedling placement seat is fixedly installed at the tops of the two first fixing sleeves, and a second seedling placement seat is fixedly installed at the tops of the two first supporting shafts; second supporting shafts are movably connected to the inner walls of the two second fixing sleeves in an inserted mode, a first seedling placing plate is fixedly installed at the tops of the two second fixing sleeves, and a second seedling placing plate is fixedly installed at the tops of the two second supporting shafts. According to the seedling cultivation device for cotton breeding, the lower surface of a second seedling placement seat can be attached to a first seedling placement seat, at the moment, the occupied space of the device is greatly reduced, the device is conveniently pushed to move, and meanwhile the device is conveniently transported.

Description

technical field [0001] The invention relates to the technical field of cotton breeding, in particular to a seedling cultivation device for cotton breeding. Background technique [0002] Cotton breeding is based on different germplasm resources of cotton. Through genetic improvement, cotton varieties with high production potential, excellent fiber quality or some special characters and suitable for planting in certain areas are selected and bred. [0003] When breeding cotton, the cotton seedlings need to be placed in a seedling box for cultivation. The seedling box provides the cotton seedlings with the required temperature and humidity, but when more types of cotton need to be bred at the same time, the The space is far from enough, so generally, multiple cotton seedlings are placed on the placement rack, and at the same time, the placement rack is moved to the nursery greenhouse for unified cultivation. [0004] However, most of the existing placement racks are fixed and ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention discloses a seedling cultivating device for cotton breeding, in order to solve the problem in the above-mentioned background technology that most of the existing placing frames are fixed and welded, and the placing frames are directly fixed and installed in the seedling cultivation shed , so that the placement frame cannot be moved. When it is necessary to change the position, or to move the placement frame out of the nursery greenhouse at the end of the seedling cultivation, it is more cumbersome. It is necessary to disassemble the placement first and then move it.
