Answer: Chang Zongtang, a consultant from the Old Association of Science and Technology in Yangling Demonstration Zone and a researcher at Northwest A&F University, said that there are two methods for fast eggplant germination: 1. Soaking seeds in warm soup. Put the seeds in warm water at 55°C, add boiling water while stirring, keep the water temperature at a constant temperature of 55°C, 15 minutes later, add cold water to 30°C, continue to soak in warm water (about 25°C) for about 8 hours, and use fine sand Rub off the mucus on the seed coat, wash and dry it, spread it out for 8-12 hours, soak it for 4-6 hours, and then spread it out again for 8-12 hours, until the hands are wet and not sticky before sprouting . This process allows water to slowly penetrate into the seeds, preventing the seed coat from absorbing excessive water and affecting air permeability.
2. Change temperature to accelerate budding. That is, every day 25～30℃ control for 16～18 hours, 16～20℃ control for 6～8 hours, so that budding is faster and neater than constant temperature. Qi seedlings can emerge in 5-6 days. The temperature of the eggplant is changed to accelerate the budding to germinate earlier, and the seed buds are strong and consistent. It is performed alternately every day and night at 30°C for 16 hours and 20°C for 8 hours. The seeds are turned once every 3 to 4 hours to facilitate ventilation and uniform heating. Panning should not be frequent. Generally, panning is not necessary for the first two days. On the third day (the seeds start to germinate), panning can be done once. After panning, let it dry for 4-6 hours before continuing to germinate.

Gantry Type Video Measuring Machine
The gantry-type Video Measuring Machine can efficiently detect the contours, surface shapes, dimensions, angles, and positions of various workpieces. It is mainly used to measure the size and angle of parts and components that are difficult or impossible to measure with a caliper and angle ruler but play an important role in assembly. It can also be used to take pictures of some parts and components to analyze the causes of defects, especially for PCB boards, films, protective films, optical glass, electronics, large sheet metal parts, connectors, precision mechanical parts, electronic components, semiconductor components, and other industries, It can achieve rapid and accurate detection in large quantities.
advantage:
1. Adopting a high-power industrial high-definition color CCD and a continuous automatic zoom depth lens with fixed frame position, the zoom rate does not require calibration, greatly improving work efficiency and measurement accuracy.
2. Images can be output to electronic computer software for surveying and mapping engineering storage. It can be used for photography, copying, and storage.
3. It can inspect the specifications of buried holes, pipe trenches, etc. on the upper surface of the tested object block. The image and color tone on the surface of the product workpiece can be clearly seen.
