Specifications: can be customized according to customer requirements
Processing range: steel, stainless steel, non-ferrous metal with an elongation of δ ≥ 10% and extrusion of internal threaded through holes or blind holes with SiO content of ≤10% aluminum-silicon alloy, high requirements for threaded bottom holes and processing conditions
Product advantages: Squeeze taps, which achieve excellent surface quality while increasing the static and dynamic strength of the threads. The thread depth is unrestricted due to the elimination of chip removal, so process safety is excellent. Extrusion taps have high rigidity and wear resistance, and the processing dimensions are stable, especially when machining small diameter threads. At the same time, because the processing thread is almost the last process, its quality and stability are the first considerations! Als, high-temp alloys, hardend materials.
Symptoms and correction of soybean deficiency
Symptoms of soybean deficiency: In the early stage, the new leaves are light yellow-green, but the old leaves are normal; in severe cases, the whole plant turns yellow, the leaves are small, and the internodes are short; the roots are elongated and the nodules are poorly developed. Soybean Sulfur Content According to Bansal (1983), the critical value of sulfur content in soybeans was 0.15% at 36 days of growth and 0.19% at 60 days of growth. The cutoff value of N:S in vivo is 16.5:1. The critical value of soil available sulfur in soybean fields: calcium chloride (0.15%) extraction method is 14 mg S / kg; monocalcium phosphate extraction method is 14 mg S / kg; Morgan extract method is 8 mg S / kg; The extraction method of ammonium acetate (0.5 mol/L) + acetic acid (0.25 mol/L) was 8 mg S/kg. Correcting the application of sulphur fertilizer to soybean sulphur deficiency not only increases yield, but also increases seed fat and protein content. Generally, the amount of sulfur fertilizer is 20-40 kg sulfur/ha. According to China's six soybean sulphur fertilizer test statistics, the increase rate is 6.4%-33%, with an average increase of 15%. Soybeans that apply sulphur fertilizer and urea in the Pacific High Islands increase production by 21%-45% compared to urea alone. (China Fertilizer Information Network)
