为有效解决茄果类蔬菜残体处理问题,以茄果类蔬菜残体为原料,以鸡粪、发酵菌剂为添加物,研究不同配比发酵残体与商品育苗基质配成的复合基质对四季豆种子萌发、秧苗素质、叶片SPAD值及SOD、POD和CAT等抗氧化酶活性的影响.结果表明:与对照相比,复合基质中加入1/4无添加物完成发酵的茄果类蔬菜残体,四季豆秧苗的真叶SPAD值、根系长度和根系表面积分别增加30.74％、31.09％和43.15％(P＜0.05),SOD、POD和CAT等抗氧化物酶活性分别提高5.74％、6.07％和4.77％(P＜0.05);复合基质中加入1/4添加了鸡粪完成发酵的茄果类蔬菜残体,四季豆秧苗真叶SPAD值、SOD和POD等抗氧化酶活性分别提高27.26％、2.04％和2.18％(P＜0.05);复合基质中加入1/4添加了鸡粪和发酵菌剂完成发酵的茄果类蔬菜残体,四季豆秧苗SOD、POD和CAT等抗氧化物酶活性分别提高4.10％、4.23％和4.39％(P＜0.05).因此,复合基质中加入1/4无添加物完成发酵的茄果类蔬菜残体,适用于四季豆育苗;复合基质中加入1/4添加了鸡粪、或者添加了鸡粪和发酵菌剂完成发酵的茄果类蔬菜残体,也可用于四季豆育苗.
Abstract
To better address the disposal problem of vegetable residues of Solanaceae,this paper studied the effects of the compound substrate on common bean seed germination,seedling quality,SPAD value,and antioxidant enzyme activities by using vegetable residues of Solanaceae as raw materials,chicken manure,and fermentation bacterial agents as additives.The results showed that when compound substrates were mixed with 1/4 of fermented Solanaceae residues without additives,the leaf SPAD value of common bean seedling increased by 30.74％(P＜0.05),the length and surface area of common bean seedling root increased by 31.09％and 43.15％,respectively(P＜0.05).Superoxide dismutase(SOD),Peroxidase(POD)and Catalase(CAT)enzyme activities of common bean seedling increased by 5.74％,6.07％and 4.77％,respectively(P＜0.05).Also,when compound substrates were mixed with 1/4 of fermented Solanaceae residues with chicken manure,the leaf SPAD value of common bean seedling increased by 27.26％(P＜0.05).Superoxide dismutase(SOD)and Peroxidase(POD)enzyme activities of common bean seedling increased by 2.04％and 2.18％(P＜0.05).Moreover,when compound substrates were mixed with 1/4 of fermented Solanaceae residues with chicken manure and fermentation bacterial agents,Superoxide dismutase(SOD),Peroxidase(POD)and Catalase(CAT)enzyme activities of common bean seedling increased by 4.10％,4.23％and 4.39％,respectively(P＜0.05).Therefore,compound substrates mixed with 1/4 of fermented Solanaceae residues without additives,or 1/4 of fermented Solanaceae residues with chicken manure,or 1/4 of fermented Solanaceae residues with chicken manure and fermentation bacterial agents,were suitable for common bean seedling cultivation.
