本文通过皖棉 1 3不同温度、不同时间处理的种子的发芽试验研究 ,探明了皖棉 1 3棉种在不同温度和处理时间下的发芽特性 ,模拟出了拟合度很高的回归方程 ,并求出皖棉 1 3能正常发芽的耐温临界值为 69.5℃。研究也表明 ,在 60℃下处理80 min的皖棉 1 3棉种 ,仍然能够正常发芽并形成健康幼苗 ,超出了工业上设定的最高温度界限 ,为改进棉种泡沫酸脱绒加工工艺提供了理论依据。
In this paper, we studied the germination characteristics of seed treated with different temperature and different time in Wanmian 1 3, and proved the germination characteristics of 13 cotton cultivars at different temperature and treatment time. The regression equation with high fitting degree , And find the cotton paddy 13 normal germination temperature threshold is 69.5 ℃. The study also showed that cotton bollworm, which was treated at 60 ℃ for 80 min, could still germinate normally and form healthy seedlings, which was beyond the maximum temperature limit set by industry. The theoretical basis.
