攀枝花煙區(qū)土壤水溶性氯含量及其氯肥適宜用量研究

　　摘 要：氯是煙草必需的營養(yǎng)元素，參與煙草的生長發(fā)育和生理生化反應(yīng)，并最終影響煙葉的質(zhì)量。為明確攀枝花煙區(qū)土壤水溶性氯含量狀況、探明氯肥施用標(biāo)準(zhǔn)，通過多年多點調(diào)查和田間試驗，研究了攀枝花煙區(qū)適宜的氯肥施用量及其對煙葉產(chǎn)量、質(zhì)量的影響。結(jié)果表明，攀枝花煙區(qū)土壤水溶性氯變幅為0.20～35.34 mg·kg-1，平均為（12.64±7.70 ） mg·kg-1，76.51%的土壤水溶性氯含量低或極低（<20 mg·kg-1）；仁和煙區(qū)、米易煙區(qū)和鹽邊煙區(qū)分別有76.93%，65.97%和89.84%的土樣水溶性氯含量低或極低（<20 mg·kg-1）；適當(dāng)施用氯肥可以提高煙葉產(chǎn)量及產(chǎn)值。綜合考慮，土壤氯含量、煙葉產(chǎn)量、產(chǎn)值、化學(xué)成分協(xié)調(diào)性、以及煙葉氯含量的安全性，建議米易煙區(qū)、仁和煙區(qū)和鹽邊煙區(qū)3個產(chǎn)區(qū)氯肥使用量分別為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.
