Problems solved by technology

[0006] In the conventional cognition in this field, if the size of the tip (that is, the aperture size of the suction hole of the tip) is too large, the anther and the pistil may be sucked into the anther and the pistil at the same time during the suction process, which may cause the anther and pistil selfing, increasing the self-pollution rate

Abstract

The invention relates to a suction head used for rice castration equipment. The rice castration equipment is used for sucking and removing anthers in spikelets of rice ears, when the rice castration equipment is operated, the suction head is close to the anthers in the spikelets and sucks the anthers through the suction force generated by the rice castration equipment, wherein the suction head isprovided with a suction hole, and the bore diameter of the suction hole is 3-8 mm. In addition, the invention further relates to the rice castration equipment comprising the suction head and a corresponding rice castration method.

Description

technical field [0001] The present disclosure relates to the technical field of rice hybridization, and in particular, the present disclosure relates to a device for detasseling rice, a suction head included in the device and a rice detasseling method. Background technique [0002] Rice hybridization technology is an essential skill for rice genetic improvement, breeding and molecular biology research. Rice hybridization technology usually includes the main steps of ear selection, detasseling and pollination control, among which the most critical link is detasseling. Complete detasseling, simple operation, high efficiency and no damage to the pistil are the standards for measuring detasseling technology and the basis for ensuring the success of hybridization. [0003] There are usually several spikelets on the rice spike, and each spikelet includes glume, anther and pistil. When the spikelets are not blooming, the glumes close to enclose the anthers and pistils in the glum...
