摘要
在中性紫色土上,施氯50～800ppm时,红麻植株生长正常,按红麻纤维产量衡量,其耐氯临界值为800～950ppm。在施氯50～400ppm时,可明显增加红麻的纤维长度和强力。但施氯800ppm时,品质开始变劣。从产量和品质综合衡量,红麻的耐氯临界值为800ppm。
The amberihemp grows normally at the Cl concentration from 50 to <800 ppm. Measured the critical value of Cl tolerance by the fibre yield, it is 800 to 950 ppm. When the Cl^- concentration at 50 ppm to 400 ppm is added to the soil, Cl can make the fibre length and intensity of ambreihemp improving. When the Cl^- concentration of 800 ppm is added to the soil, the quality begins to decrease. Measured the critical value of Cl tolerance by the yield and quality, it is 800 ppm.
