【摘要】 研究了郁金香露地栽培、地表覆盖稻草栽培和在覆草基础上喷施抗衰老剂情况下植株的衰老过程和各级新种球的收获量。结果表明地表覆盖稻草和覆草基础上喷抗衰老剂能延缓郁金香叶片叶绿素的分解,推迟植株枯苗,增加收获新种球的总重量和一、二级种球的数量,而两者相比又以喷抗衰老剂的效果更好。更多还原

【Abstract】 Cultivation of tulip in the soil with no cover, straw covering and straw covering with the plants sprayed anti-senescence reagent was studied. Results showed that the straw covering and the plants sprayed with anti-senescence reagent delayed the hydrolysis of the leaf chlorophyls and died later, that increased the total new bulb weight and getting more first and second grades bulbs, the tulip plant sprayed anti-senescence reagent produced better harvest.更多还原
