采用田间试验的方法,研究了日光温室中风化煤用量对茼蒿养分吸收、产量及品质的影响。试验结果表明:施用风化煤促进了茼蒿对N、P、K养分的吸收,产量提高6.28%～45.33%,植株维生素C含量显著增加(P<0.05),总糖、糖酸比明显增加,有机酸含量明显下降,硝酸盐含量显著降低,健康品质得到了改善。
Field experiments were conducted to study the effects of the amount of weathered coal in solar greenhouse on nutrient absorption, yield and quality of Artemisia selengensis. The results showed that the application of weathering coal promoted the absorption of N, P and K nutrients in Artemisia selenges, the yield increased by 6.28% -45.33%, the content of vitamin C in plants increased significantly (P <0.05), the total sugar, Acid content decreased significantly, nitrate content decreased significantly, the health quality has been improved.
