Open field cultivation

Open field cultivation has a large area in North China. Generally, seedlings are cultivated in windbreak impotence or plastic sheds in mid-March, planted in open fields in mid-to-late April, and harvesting begins in early June. This cultivation method is more than 20 days in the morning compared with winter melon, which supplements the blank period of winter melon supply, and the economic benefits are significantly higher than winter melon cultivation.

The nursery period of open field cultivation is from March to April, and the outside temperature rises day by day, but occasionally frost may appear at night. Therefore, the temperature management should be strengthened in the seedbed, pay attention to ventilation and cooling during the day to prevent excessive temperature, and avoid frost damage at night. 7 to 10 days before planting, gradually increase the amount of ventilation, and then remove the plastic film, so that the seedlings are exposed to the ground and enhance their adaptability. Other matters of seedling management are the same as those of early maturing spring.

When the seedling age is 30 to 35 days, 3 to 4 true leaves, and the external night frost is out of date for colonization. Field management etc. refer to early spring maturity cultivation.

Full Automatic Video Measuring Instrument

The fully automatic image measurement instrument is an artificial intelligence modern optical non-contact measurement instrument developed on the basis of the digital image measurement instrument (also known as CNC image instrument). The fully automatic image measuring instrument inherits the excellent motion accuracy and motion control performance of digital instruments, integrates the design flexibility of machine software, and belongs to the forefront of optical size detection equipment today.

The full-automatic anime image measuring instrument is based on the CCD digital image, relying on the computer screen measurement technology and the powerful software capability of spatial geometry operation. After installing specialized control and graphic measurement software, the computer becomes the measurement brain with the soul of the software and is the main body of the entire device. It can quickly read the displacement value of the optical ruler and obtain the desired result instantly through software module operations based on spatial geometry; And generate graphics on the screen for the operator to compare the images and images, so as to visually distinguish possible deviations in the measurement results. All of this is done in real-time in front of powerful computer computing power, and the operator himself cannot detect it. This kind of precision instrument that can use CCD digital image, through computer software operation, to meet the needs of complex measurement is the real image measuring instrument, anime.
