Preservation device and system capable of prolonging service life of sunflower pollen

Abstract

The invention belongs to the technical field of sunflower cross breeding, and particularly relates to a storage device and system capable of prolonging the service life of sunflower pollen. The storage device comprises a base, a storage tank is arranged at the upper end of the base, and a plurality of heat preservation blocks are arranged in an inner cavity of the storage tank in an array mode; a plurality of thermal insulation storage blocks are arranged in the storage tank, a plurality of taking and placing doors corresponding to the thermal insulation storage blocks are arranged on the outer wall of the storage tank, a plurality of heat conduction mechanisms are arranged on the sides, close to the center of an inner cavity of the storage tank, of the thermal insulation storage blocks, and an independent pollen storage bottle is inserted into each heat conduction mechanism. When the pollen is taken, the low-temperature nitrogen in the center of the inner cavity of the storage tank cannot leak, so that the loss of the low-temperature nitrogen is reduced, the stability of the storage temperature of other independent pollen storage bottles is ensured, the storage cost is saved, and the storage quality is improved.

Description

technical field [0001] The invention belongs to the technical field of sunflower hybrid breeding, and in particular relates to a storage device and system capable of prolonging the lifespan of sunflower pollen. Background technique [0002] Sunflower is the fourth largest oil crop in the world. The sown area and total output of sunflower have been on the rise in recent years. Among the various factors of sunflower yield growth, improved varieties account for about 35% to 40%. Therefore, cultivating new varieties with high yield and high quality is the primary measure to ensure the development of sunflower industry. The experimental data clearly prove that under the conditions of proper selection of varieties and mentors, heterologous pollen-assisted pollination has a good influence on the viability and productivity of the offspring of sunflower self-pollinated plants. Furthermore, and importantly, aftereffects of heteropollens affect some shapes such as height, length of gr...

AI Technical Summary

Problems solved by technology

If the lifespan of the stigma and pollen is mastered, and the flowering period of the male parent and the female parent are not far apart, it is not necessary to sow in stages, and the pollen of the male parent that blooms early can be taken down and stored to a certain extent and can still be used for pollination. Fruiting, to achieve the expected hybridization plan. In the prior art, the male parent pollen collected in advance is usually stored in liquid nitrogen after low-temperature freeze-drying. However, when the pollen in the low-temperature storage device is taken out, it needs to be opened as a whole. , This will lead to a large amount of low-temperature nitrogen overflow. Since the pollen will be taken in batches during use, the nitrogen overflow caused by repeated use will cause fluctuations in the temperature in the low-temperature storage equipment and affect the preservation effect of the pollen. For this reason We propose a preservation device capable of extending the lifespan of sunflower pollen
