A high yield of tomato to see the flowers, two to see the fruit

First, look at the flower phase

1, thin flowers. The tomato flower ear is small and the flowers are less, and the angle between the panicle and the main stem is obviously smaller than the normal panicle angle. The main reason is that the night temperature in the room after colonization is too high and the tomato root volume is small. In the case of pouring enough water for planting, diligently cultivating and loosening soil, reducing the greenhouse temperature at night, controlling the promotion, appropriate seedlings, flowering will be normal. Of course, slender florets also have a relationship with flower bud differentiation at seedling stage.

2, less buds. When the buds appeared, there were only 2-3 buds. After removing ghost flowers, only 1-2 were left. This condition is mainly due to the small temperature difference in the flower bud differentiation stage at the seedling stage, the high seedling density, the poor root development, and the formation of weak seedlings. During the nursery period, when the seedlings grow to 2 leaves and 1 heart, the seedlings should be separated in time, and the temperature difference should be widened to cultivate age-appropriate seedlings and normal buds.

3, ghost flowers. The first flower in the flower of each ear of a tomato is large and has many petals. The result is mostly malformed fruit. People often call this kind of flower a "ghost flower." Ghost flower is the performance of the normal growth of tomatoes, generally in the production of ghost flowers removed.

Second, look at the fruit

1, malformed fruit. There are many types of tomato misshapen fruit, such as pointed fruit, empty fruit, perforated fruit, split fruit, twin fruit, chrysanthemum fruit, elliptic fruit, and eccentric fruit. Spike fruit is due to the use of high hormone concentrations or repeated pharmacotherapy. Perforated fruit flower bud differentiation stage encountered low temperature and insufficient light. Formula fertilization is used to strengthen seedling management, strictly control the concentration of hormones used, and make indoor a suitable temperature and humidity conditions, in order to reduce the occurrence of teratogenic fruit.

2, brown fruit. The brown fruit matures and turns red, but brown or brownish brown is revealed on the red fruit surface, causing the fruit to be dirty and the gloss to be poor, which affects the appearance of the fruit. Physiological diseases, mostly in the partial application of nitrogen fertilizer, low temperature conditions occur.

3, green fruit. After the green cherries turn pink or red, green patches or green areas still remain near the shoulders or fruit peduncles. They remain unchanged and appear red and green, but the green areas are hardened, and the pulp is sour. decline. The main reason is that partial application of nitrogen fertilizer, lack of potassium fertilizer and boron, dry soil is also a cause.

4, brown fruit. Brown-brown fruit is actually a tendon rot. There are two types of brown and white variants, and there is less incidence of cultivars in winter in greenhouses. The rot disease is a physiological disease. The degree of damage depends on the species, light intensity, and the ratio of nitrogen, phosphorus, and potassium in the soil. The density of tomatoes in the greenhouse is too large, and the amount of air is small. Long-term foliation is also the cause.

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.

The fully automatic image measuring instrument has a wide range of applications in precision electronics, wafer technology, cutting tools, plastics, precision parts, springs, stamping parts, connectors, molds, military industry, two-dimensional reading, drawing, engineering development, hardware and plastic, PCB board, conductive rubber, powder metallurgy, screws, clock parts, mobile phones, pharmaceutical industry, fiber optic devices, automotive engineering, aerospace, higher education institutions, research institutes, and other fields.
