An auxiliary device for cultivating rice flowers

Abstract

The invention discloses a rice anther culture breeding auxiliary device. The device is characterized by comprising the following parts: a sterilizing water tank and a disinfectant tank, which can sterilize and clean inner cavity of the device and spikes of rice, and create a sterile condition; a rocker panel, which can achieve fully mixing of spikes of rice, disinfectant fluid and disinfected water; a the link mechanism, which can achieve reciprocated movement of the rocker panel; a drain pipe, which can smoothly discharge waste liquid in the tank; a cutting board and a blade group, which can achieve rapid segmentation of spikes of rice; a storage bin, which can collect segmented rice spike slices; and a conveyor belt with triangle projection, which is convenient for lateral convey and cutting of spikes of rice; The device provides a sterile conditions for transverse cutting of spikes of rice, provides a large number of sterile slices of rice spike for further centrifugation extraction of rice anther for anther culture; and the device cuts spikes of rice, centrifuges and extracts anther for rice anther culture breeding, and can greatly improve the efficiency of anther culture, and significantly reduce the breeding costs.

Description

technical field [0001] The invention relates to an auxiliary device for cultivating rice flowers and belongs to the field of agricultural machinery science and technology. Background technique [0002] Anther breeding is a breeding method in which anthers are cultivated into haploid plants, and then chromosomes are naturally or artificially doubled to obtain homozygous diploids, so anther breeding is also called haploid breeding. Rice is one of the most important food crops in the world. In 1968, the cultivation of rice anthers was successful. Subsequently, the use of this technology to breed rice varieties has attracted the attention of breeders from all over the world. The main characteristics of rice anther culture and breeding are shortening the breeding cycle, improving selection efficiency, and accelerating the transfer of effective traits. Rice anther cultivation and breeding has been combined with conventional hybrid breeding, distant hybrid breeding, mutation bree...

Problems solved by technology

Years of practical experience have found that the most important reason for the low efficiency of flower cultivation is the limitation of the operation method of flower cultivation

The method of cutting glumes and shaking herbs is currently the most common operation method for rice anther separation. However, the process of glume cutting and shaking herbs requires professional tissue culture operations and consumes a lot of labor, which has become the speed-limiting step of rice flower cultivation operations.

How to quickly separate rice anthers, and ensure that the rice anthers after separation maintain vigor and pollution-free and suitable for in vitro culture is the key to solving the low efficiency of flower culture operations
