Thermostatic male-killing device for rice seed production

Abstract

The invention relates to a thermostatic male-killing device for rice seed production, belonging to the technical field of plant genetic breeding technology. The thermostatic male-killing device for rice seed production is characterized in that a container body (1) is located in an outer shell (2), a middle electric heating device (3) is arranged at the middle part inside the container body (1), and a bottom electric heating device (4) is arranged at the bottom; a bottle cap (6) is arranged at the bottleneck which is at the upper part of the container body (1); a handle (5) is arranged at the outer side of the outer shell (2); a thermostatic control device (8) is arranged at the upper part of the outer side of the outer shell (2), and an externally connected power socket (7) is arranged at the lower part of the outer side of the outer shell (2); the middle electric heating device (3), the bottom electric heating device (4) and the thermostatic control device (8) are connected with the externally connected power socket (7) through wires and are connected with an outer power source. The thermostatic male-killing device controls temperature in the male-killing device automatically through a thermostatic controller, and the temperature after being set is kept constant basically, so that the high-temperature male-killing effect is guaranteed, the male-killing accuracy is improved, the labor intensity is reduced, and the work efficiency is increased.

Description

Technical field:

[0001] The invention relates to a constant-temperature detasseling device for rice seed production, belonging to the technical field of crop genetics and breeding. Background technique:

[0002] Rice is a self-pollinating crop, and some characteristics of the flower structure make self-pollination dominate the whole pollination process, and its natural hybridization rate is generally below 5%. Introducing exogenous genetic material and improving the genetic quality of rice varieties is an important way to improve rice production potential. Due to the existence of self-pollination, the male organs of this variety must be given adversity to inactivate them and lose their pollination ability when introducing foreign genetic material.

[0003] High temperature detasseling is a common method in rice breeding. The principle is to use the difference in response to temperature between the male and female pistils in rice flower organs, and the principle that the in...
