摘要
采用盆栽接种法,将6株土壤环境有益菌制成固体菌剂,在播种生菜种子和播种后三周各施加一次于花盆中,接种量为0.6%,以研究微生物固体菌剂对美国大速生菜(不结球生菜)和美国结球生菜的促长作用。结果表明,6株环境有益菌的固体菌剂对两个生菜品种促长作用非常明显。不同的微生物固体菌剂对其促长效果有异,菌株Y_(1)、D-9和Y_(8)固体菌剂对不结球生菜的促长效果较好,Y_(8)和D-9固体菌剂对结球生菜的促长效果较好。用于制备固体菌剂的基质是由农产品的副产品及有机废弃物组成,经过高温、高压灭菌之后作为空白对照施入花盆,对生菜的生长也有一定的促进作用。总之,6株环境有益菌的固体菌剂对不结球生菜和结球生菜都有很好的促进生长作用,其中菌株D-9和Y_(8)的固体菌剂对两个生菜品种都有很好的促长作用,有望进一步应用于生菜的大田生产中。
The method of inoculating environmental beneficial bacteria in pots was used for this experiment.Solid bacteria agents of six strains of environmental beneficial bacteria were applied to pots when the lettuce seeds sown and three weeks after sowing,respectively.The inoculation amount was 0.6%.The purpose was to study the effects of environmental probiotics on the growth of American Fast Lettuce(non-heading lettuce)and American Heading Lettuce.The results showed that the growth indexes of lettuce demonstrated that the growth-promoting effect of the six bacteria strains on two lettuce varieties were very obvious.However,the solid agents of different environmental beneficial strains had different effects on the growth of two lettuce varieties.The solid agents of strains Y_(1),D-9,and Y_(8)had the best effect on the growth of non-heading lettuce,and the solid agents of strains Y_(8)and D-9 had the best effect on the growth of heading lettuce.In addition,the medium was used to prepare solid agent for environmental beneficial bacteria was composed of by-products of agricultural products and organic waste.After high temperature and autoclaving treat,it was used as a blank control in planting pots,which also had a certain promoting effect on the growth of lettuce.In short,the solid agents of the six strains have growth-promoting effects on lettuces.Among which the solid microbial agents of D-9 and Y_(8)had very significant growth-promoting effects on two lettuce varieties,which is expected to be further application in the field production of lettuces.
