Description

Technical Field

[0001] The invention relates to a multi-purpose experimental box for rice hybrid breeding and pollination, and belongs to the technical field of equipment for testing or processing seeds, rhizomes or the like before sowing or planting. Background Art

[0002] Rice cross-pollination is a key step in the selection and breeding of new rice varieties. Through cross-pollination, the excellent genes of different rice varieties can be aggregated to cultivate excellent new varieties. At present, the main method of rice cross-pollination is to directly cross-pollinate in a natural environment, but this method of cross-pollination experiment is short in duration and easy to cross-pollinate. Cross-pollination experiments cannot be carried out in low temperature and rainy weather. The main reason is that the impact on the environment is not controllable.

[0003] After cross pollination, similar problems also exist in the rice seedling raising process. When raising seedlings directly in a natural environment, external organisms or microorganisms in the environment and abnormal temperature and humidity may weaken the relationship between the seedling raising results and the rice variety, making it difficult to distinguish between environmental factors and rice variety factors in the seedling raising results. The main reason is that the impact on the environment is not controllable. Summary of the invention
