How to manage the greenhouse tomato after the spring?

Now that it is spring, after the spring, the management of greenhouse tomatoes needs to be further adjusted. Then, how should the greenhouse tomato be managed after the spring?

When the tomato grows to this point, the root system begins to appear aging, which shows that the activity of the old roots is reduced, and the new roots are not able to go down. Therefore, the root group is shallow, the ability to absorb nutrients and water is decreased, and the growth of the tomato is weak, and the nutrient required for fruit expansion in this period is more. Therefore, in addition to timely topdressing to meet the needs of tomato growth, it is more important to promote the roots under the tie, only the deeper the tomato roots, can absorb more water and nutrients, if the roots are shallow, apply more fat tomatoes Can not absorb the same. At this time, the root system and the topdressing are promoted simultaneously. When watering, apply 14-16 kilograms of fermented per liter of vegetable Lele, and apply 300 grams of steam bun. When using it, first dissolve the vegetable Lele and fertilize with a large amount of water, and then apply it with water. Be careful to pour small water and the water should not be too large.

Germanium Lens

Germanium Plano-Convex (PCX) Lenses feature precision diamond turned surfaces making them ideal for a variety of infrared applications, including thermal imaging, infrared spectroscopy, and remote sensing. Germanium (Ge) is popular for its high index of refraction, broad transmission range, and rugged mechanical properties. These lenses are available in 25 and 50mm diameters, uncoated, or with multiple broadband coating options.

Germanium (Ge) material feature high index of refraction (around 4.0 from 2 - 14μm), an anti-reflection coating is recommended on these germanium windows for sufficient transmission in the region of interest. Germanium is subject to thermal runaway, meaning that the transmission decreases as temperature increases. As such, these germanium windows should be used at temperatures below 100°C. Germanium`s high density (5.33 g/cm3) should be considered when designing for weight-sensitive systems. Ge properties
