The kidney bean is a self-pollination plant, and the cross-pollination is only 0.2% to l%. In order to maintain the purity of the fine variety, different varieties should be spaced more than 100 meters apart. Dwarf species should choose to leave the middle fruit of the strong and disease-free plants for seeding. The vine species should be selected to retain the base and middle part of the plant, that is, the pods below the vine 1/3 height; the pods in the upper part of the plant are not full of seeds and should not be selected for retention. In addition to the seedlings except the species, the rest of the nurses should be removed. The seed development of kidney bean is completed approximately 25 to 30 days after flowering. When the pod turns from greenish yellow to yellow, when the twists and turns do not break easily, it is matured and harvested in time. Seeds for spring sowing can be harvested in spring last year or in autumn, but better in autumn last year. Because of the autumn seeding, the seeds are full and full, the germination rate is high, and the emergence is also neat. The germination rate of seeds can generally be maintained for 3 years, but the seeds harvested in the previous year are mostly used in production. Brand computer chips, dual-frequency integrated circuits, cross-magnetic induction detection, bringing higher accuracy, reliability and stability. 2. Automatic control system, using special magnetic materials and unique technology, the detection accuracy of the probe is particularly high, and the accurate position of the broken needle is displayed in 8 detection areas. 3. Dual probe design, double detection function, higher safety performance, compared with other types of needle detectors, at the same detection height, the sensitivity is increased by 10%. 4. Automatic detection, automatic induction, automatic stop when no detection is needed, 0-10 sensitivity adjustment, when there is a broken needle, the conveyor belt automatically stops and returns backwards. 5. With a counting function, it can count the number of qualified or unqualified products. 6. It has two alarm modes: sound effect and light alarm. 7. Luxurious appearance, novel style, time-saving and power-saving, simple operation Rapid PCR detection,Rapid Detection Rapid Detection PCR Kit Viral Antigen Detection Jiangsu iiLO Biotechnology Co., Ltd. , https://www.sjiilobiotech.com
