Particle counter sampling grass seed for research analysis

Insert grasses, especially on the surface, often due to seed germination is not neat and poor early seedling taste, grass seedlings sparse and thin. One of the ways to solve the problem is to granulate the seeds. In the greenhouse of the University of Agriculture and Technology of Japan, Agromycys sp. was used as a test variety to study the amount of irrigation water and the impact of the wrapping materials on the seedling buds and initial growth of D.galanga seeds. The weight of the coating agent is clay, calcium carbonate, and grass ash, and } mm, gmm,} mm are three areas of unirrigated water. The results were as follows: 1. Within 15 days after sowing, the plant and tree ash was used as the entrapment agent test area, and the seed germination rate was much lower than that of the smoked clay area and the calcium carbonate area. Research sampling of pasture seeds using particle counters is more convenient, and the results are more accurate and effective.

Pasture seeds sampled by particle counters, 12 days after sowing, the plant elongation rate was much slower in the specific clay area and calcium carbonate area in the plant ash area, and in the heavy clay area and calcium carbonate area, the plant growth was in the 4mete and 3 irrigation areas. the best. After planting l species 30 days later, 'the heavy clay area and the calcium carbonate army plants are still faster than the plant ash area.' Insect repellent 30, and the highest material weight for the heavy clay area, followed by calcium carbonate plant herbaceous ash area is particularly low, the test intervals vary significantly. Heavy clay pots and grass ash areas, above-ground parts of plants, underground parts, and total weight increase with the increase of irrigation volume.

For the seed obtained by the particle counter, tests have shown that when the soil moisture is insufficient, the initial germination rate is slightly lower than that of the seeds obtained from the heavy clay and calcium carbonate. However, the grass height and the dry matter weight of the later stage are different. Seeding ratio under normal humidity is almost no difference, showing the effect of seed and seed granulation. On the contrary, turfgrass has inhibitory effects on the germination and initial growth of Dactylis glomerata seeds, which is due to the idiopathic nature of the grasses and trees.

Pressure Vessel

Pressure vessels, sometimes storage tanks, are containers designed to hold liquids or gases at a pressure that differ from the ambient pressure. They are used in a variety of applications, including chemical processing, oil and gas processing, power generation, and medical applications. Pressure vessels can be made from a variety of materials, including stainless steel, carbon steel.

The design of pressure vessels must consider the pressure and temperature of the fluids, as well as other factors such as corrosion, fatigue, and creep to determine the wall thickness. Pressure vessels must be designed and manufactured in accordance with applicable codes and standards, such as GB Standard or ASME Standard.

Types of pressure vessel equipment includes Shell And Tube Heat Exchanger, Shell and Plate Heat Exchanger, container type pressure vessel, reactor, separator, and so on.
