Abstract

A large study was conducted during the 2015 growing season in Australia using a modern spindle-type cotton harvester. The aim of this trial was to establish the influence of ground speed, compressor plate pressure setting, and scrapping plates on fibre and seed quality. Fibre quality was measured by HVI, AFIS PRO, and Cottonscope, and seed quality was assessed for mechanical damage and residual lint by industry-approved methods. This study concluded that although mechanical seed damage fell within the acceptable range, the level of mechanical damaged seed increased slightly with the addition of scrapping plates and as the front and back compressor plate pressure settings were increased. In terms of fibre quality, the study observed that ground speed had little or no effect on fibre quality. However, the addition of scrapping plates, on the back compressor plate, resulted in a weak positive but statistically significant relationship in terms of strength, fineness and colour resulting in an improvement of one colour grade .

摘要

在澳大利亚 2015 年的生长季节使用现代纺锤式棉花收获机进行了一项大型研究。该试验的目的是确定地速、压缩机板压力设置和刮板对纤维和种子质量的影响。通过 HVI、AFIS PRO 和 Cottonscope 测量纤维质量，并通过行业认可的方法评估种子质量的机械损伤和残留棉绒。该研究得出的结论是，虽然机械种子损坏在可接受的范围内，但机械损坏种子的水平随着刮板的增加和前后压缩机板压力设置的增加而略有增加。在纤维质量方面，研究观察到地速对纤维质量几乎没有影响。然而，增加了报废板，
