攀枝花烟区土壤水溶性氯含量及其氯肥适宜用量研究

　　摘 要：氯是烟草必需的营养元素，参与烟草的生长发育和生理生化反应，并最终影响烟叶的质量。为明确攀枝花烟区土壤水溶性氯含量状况、探明氯肥施用标准，通过多年多点调查和田间试验，研究了攀枝花烟区适宜的氯肥施用量及其對烟叶产量、质量的影响。结果表明，攀枝花烟区土壤水溶性氯变幅为0.20～35.34 mg·kg-1，平均为（12.64±7.70 ） mg·kg-1，76.51%的土壤水溶性氯含量低或极低（<20 mg·kg-1）；仁和烟区、米易烟区和盐边烟区分别有76.93%，65.97%和89.84%的土样水溶性氯含量低或极低（<20 mg·kg-1）；适当施用氯肥可以提高烟叶产量及产值。综合考虑，土壤氯含量、烟叶产量、产值、化学成分协调性、以及烟叶氯含量的安全性，建议米易烟区、仁和烟区和盐边烟区3个产区氯肥使用量分别为20，25，30 kg·hm-2。

　　Abstract： Chloride is a necessary nutrient for tobacco， participates in the growth and physiological and biochemical reactions of tobacco， and ultimately affects the quality of tobacco leaves. In order to determine the water-soluble chloride content of Panzhihua tobacco-growing soil， to clear an application standard and an appropriate amount of chloride fertilizer and its effect on the yield and quality of tobacco leaf in Panzhihua tobacco area， the multi-point survey and the field experiments were carried out through three years at four test places. The results showed that the available chloride variation of soil in Panzhihua tobacco-growing soil was 0.20～35.34 mg·kg-1， with an average of （12.64±7.70） mg·kg-1 and 76.51% of the soil was low or extremely low （< 20 mg·kg-1）. There were 76.93%， 65.91% and 89.84% of the soil samples the available boron content was low or extremely low （< 0.5 mg·kg-1） in Renhe county， Miyi county and Yanbian county， respectively. The application of chloride fertilizer could increase the yield and the value of tobacco leaf. Considering chlorine content in soil，tobacco leaf yield，output value， coordination of chemical compositions， and the safety of the content of chlorine， we suggested that the chloride fertilizer usage was 20， 25，30 kg·hm-2 in Miyi， Renhe and Yanbian， respectively.
