在无花生线虫病害的均沙质壤土地和线虫病害高发区的沙质潮土地，用复合微生物肥对花生进行了拌种、浇灌及浇灌加喷施的作用和效果试验，有促进花生生长、防治花生线虫病害及显著增产的作用，在均沙质壤土不施基肥和追肥的条件下，花生增产９．５％～１８．１％，其中浇灌方法增产１７．６％。在花生线虫病害高发区，对花生线虫病的防治效果为３４．４％～５６．８％，增产２３．４％，投入产出比为１１２．４～１１６．９ In sandy loam without soil of peanut nematode disease and sandy tide land with high incidence of nematode disease, peanut was treated with compound microbial fertilizer for seed dressing, watering, watering and spraying, and the effect test to promote peanut growth, Peanut nematode disease and significant increase of yield. In the condition of non-application of basal fertilizer and topdressing, sandy peanut yield increased by 9.5% ~ 18.1%, among which the irrigation yield increased by 17.6%. In peanut nematode disease-prone areas, the control effect on peanut nematodes was 34.4% ~ 56.8%, increased by 23.4% and input-output ratio was 112.4 ~ 116.9
