为测定生物有机肥在田间对西葫芦生长影响及根结线虫防治效果,使用由不同菌株发酵的生物有机肥处理西葫芦及根结线虫发生严重的区域,结果表明:与对照相比,使用生物有机肥后,首先可显著提高植株茎粗、叶绿素含量、地上及地下生物量;其次可显著降低土壤中根结线虫二龄幼虫密度、根结指数和单株根系虫卵数,明显减轻根结线虫田间发病率,最高防效可达63.00%;同时还可显著提高土壤中自由线虫数量。因此,使用生物有机肥能显著提高西葫芦植株生物量,有效防治根结线虫的田间危害。
In order to determine the effect of bio-organic fertilizer on the growth of zucchini and the control effect of root-knot nematode in the field, the bio-organic fertilizer fermented by different strains was used to treat the serious area of zucchini and root-knot nematode. The results showed that compared with the control, , The root and shoot biomass, chlorophyll content, aboveground biomass and underground biomass were significantly increased firstly. The density of second-instar larvae of root-knot nematode, the root knot index and the number of ovum per plant were also significantly decreased, which significantly reduced the incidence of root-knot nematode in the field Rate, the highest anti-efficiency up to 63.00%; at the same time can significantly increase the number of free nematodes in the soil. Therefore, the use of bio-organic fertilizer can significantly improve the zucchini plant biomass, effectively prevent root-knot nematode field hazards.
