【摘要】 不同施肥水平与种植密度是影响薄荷生物学性状,即单株主茎叶片数、分枝数、分枝叶片数及有效叶片数的重要因素,其中分枝叶片数影响较大,可用单株分枝叶片数与主茎叶片数之间的比值反映出影响程度大小。因此,可以通过不同密度茎叶比测定,了解田间土壤肥力水平,作为施肥的重要依据,再结合施肥试验及多年生产实践,求出薄荷茎叶比、茎叶比施肥系数及施肥量公式,从而探讨了薄荷茎叶比施肥技术体系。更多还原

【Abstract】 Soil fertility and elucidative density are important factors affecting biological properties of field mint,such as total leaves of main stem,quantity of stem,total leaves of small stem,quantity of efficacious leaves among these properties,total leaves of small stem relieved more influence,and the degree of influence can be impressed by the ration of total leaves of small stem to main stem.So by means of measuring the ration of stem to leaves of different cultivate density,we can know soil fertility as an important basis for Appling fertilizer.If we combing Appling fertilizer experiment and merry years produce practice with above knowledge,we wan figure out the ration of stem to leaf,coefficient of Appling fertilizer and quantity of fertilizer needed,that is to say,we can obtain a completely system of applying fertilizer according to ration of stem to leaf.更多还原
