Sugarcane warm water emasculation method

Abstract

The invention provides a sugarcane warm water emasculation method, wherein the used device comprises a constant-temperature water bath cabinet and an auxiliary shelf. A constant-temperature water bath cabinet comprises a rectangular case body and an upper cover. The rectangular case body has an upper opening and an inner container, one side of the upper cover is hinged to the opening of the rectangular case body, a support is arranged inside the inner container and in the position close to the bottom of the inner container, an electric heating pipe and a temperature sensor are arranged below the support inside the inner container, a water circulation pump is arranged inside the inner container, and a control box is arranged on a side edge of the rectangular case body; the electric heating pipe, the temperature sensor and the water circulation pump are electrically connected with the control box; an opening, an overflow hole and a drainage hole are formed in the rectangular case body; a transparent view window is arranged in the center of the upper cover; a rustless steel wire pressing ring is fixed on the side, close to the case body, of the upper cover. Sugarcane flower spikes are put on the water surface of the water bath cabinet and sugarcane flower stalks are suspended over the opening of the water bath kettle, the upper cover is put down and the pressing ring which is fixed on the upper cover presses the flower spikes into water to realize warm water emasculation of sugarcane. The constant-temperature water bath cabinet provided in the invention can achieve the effect of flat laying of crops / plants flat to heat the terminal tissues and organs of the crops / plants in a water bath, is particularly suitable for large-batch warm water emasculation of living plant pollens and applied to large-scale standardized crops hybridization breeding production, and is convenient to operate, practical and efficient.

Description

technical field [0001] The invention relates to a water bath box suitable for pollen killing of crop plants and a sugarcane hybrid seed production method. Background technique [0002] In the traditional water bath, the design method of partially immersing the object in the water surface for heating treatment is to place the object from the upper cover and partially immerse in the water surface, which is a vertical placement. In production and experiments, for the end organs of some crop plants, such as flower organs and top growth points, when heating in a water bath, the parts immersed in the water surface are smaller and shorter, while the remaining parts exposed to the water bath are longer or heavier. It is necessary to place the exposed water bath horizontally. The organs of some plants have strict requirements on the temperature of the water bath. For example, the floral organs of crop plants require a more accurate temperature in the water bath when the pollen is ki...
