The results of sandy culture showed that the dry weight of shoot and yield of biomass of DT and DTXC decreased under low-N, low-P, low-K stress.
砂培试验表明,在低氮、低磷、低钾胁迫下,东塘、东塘西侧地上部干重、生物学产量降低;

By using pot tests, the effect of low-P stress on dark sun-cured tobacco endogenous hormone and root activities were studied during different growth stage.
通过盆栽试验和室内分析,研究低磷胁迫对晒红烟内源激素和根系活力的影响。
