【摘要】 采用1/2霍格兰(Hoagland)营养液水培法,研究辣椒植株发酵液的自毒作用及银杏叶发酵液和再腐解液对其的调控作用。结果表明,辣椒植株发酵液使辣椒受到自毒作用,根系活力下降,相对电导率增大。银杏叶发酵液加重了辣椒植株发酵液的自毒作用,并且与其浓度成正相关。银杏叶再腐解液缓解了辣椒的自毒作用,缓解效果与再腐解液的浓度有关。更多还原

【Abstract】 By applying the method of water culture with 1/2 Hoagland solution,this paper studied the autotoxicity of pepper plants’ fermentation broths and allelopathy regulation on it by gingko leaves’ fermentation broths and decomposition solutions that the fermentation broths were decomposed again after the leaves were removed.The results showed that under the autotoxicity of pepper plants’ fermentation broths,their root vigors were declined and the relative conductivity was aggrandized.Gingko leaves’ fermentation broths enhanced the autotoxicity of pepper plants’ fermentation broths,and showed positive correlation with its concentration.Gingko leaves’ decomposition solutions have alleviated the autotoxicity of pepper plants’ fermentation broths.The alleviated effects depend on the concentration of gingko leaves’ decomposition solution.更多还原
