The invention discloses a breeding and utilization method of black radish germplasm resources. Compared with radish Ogura CMS, the breeding of sterile lines is easier. All radish materials (including Ogura CMS hybrids) that do not contain orf463-specific genes can be bred into corresponding maintainer lines and sterile lines, and male-sterile hybrids can be easily prepared from NWB CMS sterile lines, which can be well protected for breeding. intellectual property rights. At the same time, various restorer lines created with the NWB CMS restorer gene contained in black radish can not only be used for the breeding of hybrid varieties, but also for the fixation and utilization of the excellent traits of NWB CMS hybrid sterile varieties on the market, reducing the loss of germplasm resources. risk and improve the utilization efficiency of germplasm resources.

The invention relates to a detection circuit and a detection method for a salt content signal of a dishwasher. The detection circuit is characterized by comprising a single chip microcomputer, a detection device and a salt concentration sensing device, wherein a salt concentration signal sensed by the salt concentration sensing device is output to the detection device, the signal is processed by the detection device and then transmitted to the single chip microcomputer, and the single chip microcomputer confirms the input signal by virtue of the detection method. The detection method comprises the following steps of: a converting and filtering stage, detecting and processing of the single chip microcomputer, and a salt content information confirming stage. The invention has the beneficial effects that through the resources of the single chip microcomputer, analog voltage signals of the salt concentration sensor can be converted into digital signals by utilizing an AD (Analog-to-Digital) converter of the single chip microcomputer to complete the detection of salt content information so as to achieve the purpose of rapidly and accurately detecting the salt content information of the dishwasher. The hardware is simpler and easy to maintain, and a software design algorithm is easy to transplant.
