Compounding agent for efficiently relieving male sterile rice panicle enclosure as well as preparation method and application thereof

Abstract

The invention discloses a compounding agent for efficiently relieving male sterile rice panicle enclosure as well as a preparation method and application thereof. The compounding agent is prepared from gibberellin 3, indole-3-acetic acid, urea phosphate, Tween 20 and azone according to a certain proportion. The preparation method comprises the following steps of (1) proportionally weighing gibberellin 3, indole-3-acetic acid and ethanol; continuously performing stirring to obtain a mixed solution A; (2) proportionally weighing urea phosphate, Tween 20, azone and water; continuously performingstirring to obtain a mixed solution B; (3) sufficiently mixing the mixed solution A and the mixed solution B to obtain the compounding agent for efficiently relieving male sterile rice panicle enclosure. The compounding agent is low in cost; the method can be easily implemented; the operation is simple and convenient; the reverse one section growth of the male sterile rice can be obviously promoted; the male sterile rice panicle enclosure is relieved; the hybrid rice breeding seed yield increase by 80.4 to 195.6 percent can be realized.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a compound agent for efficiently removing ear wrapping of male sterile rice and a preparation method thereof, which is suitable for removing ear wrapping of male sterile rice in hybrid rice seed propagation. Background technique [0002] The research and development of hybrid rice has made outstanding contributions to the grain production of our country and the world. However, the male sterile rice used in hybrid rice breeding generally has the problem of ear encapsulation, which means that the elongation of the lower internode of rice is hindered so that the ear cannot be completely drawn out of the leaf sheath of the lower leaf. In hybrid rice seed production, the male parent rice with normal panicle development does not have the problem of ear encapsulation; however, the panicle encapsulation of the female male sterile rice makes the spikelets enclosed in lea...
