Ganzi planting new technology


Ganzi likes a cool climate and is cold-resistant. The above layers are deep, loose and fertile. It is advisable to cultivate on well-drained, humus-rich sandy soil or on sticky soil. Seeds are propagated. Seeds are soaked in cold water before sowing , mixed with plant ash and new high-fat membranes to repel subterranean pests, isolate viral infections, enhance respiratory intensity, and increase seed germination rate. Spread the seeds evenly into the ditch, cover the soil and water.

Strengthen field management after cultivation to enhance plant disease resistance. Reasonable irrigation and fertilization, weeding and weeding, we must pay attention to not damage the roots when loosening the soil; remove the water in the rainy season, and remove the flower buds when flowering. And spray the medicine roots at the right time . The leaf photosynthesis product (nutrient) is transported to the root system to improve the nutrient conversion rate and the loosening ability, so that the rhizome can be rapidly expanded and the medicinal content is greatly improved. At the same time, it is necessary to strengthen the comprehensive prevention and control of pests and diseases, and spray new high-fat membrane to enhance the control effect. In the end of autumn, we must do the winter and cold insulation work to ensure safe wintering.

Meniscus Cylinder Lens

Meniscus cylinder Lens can increase the NA of the system while only adding slightly to the total spherical aberrations. The Negative Meniscus cylinder Lens is used to increase the focal length of another Cylindrical Lens while maintaining the angular resolution of the optical assembly. This lens shape is best used when one conjugate is relatively far from the cylindrical lens.

Some styles of cylindrical lenses have antireflective coatings to increase the transmission of light through the lens.
Fused silica cylinder lenses are ideal for demanding laser machining and medical applications.
