三七种植存在着严重的连作障碍,导致三七根腐病严重,产量降低、品质下降,严重制约了三七产业的发展。为了寻找一种有效克服三七连作障碍中根腐病的土壤生态控制处理方法,云南农业大学植物保护学院研究人员比较了8种不同的土壤处理方法对三七幼苗生长及根腐病发生的影响。结果表明:8种土壤处理方法对克服连作障碍都有一定的效果;对试验处理的出苗率与存苗率、生物量的积累和减少根腐病的发生进行综合评价,比较结果为:田间蒸汽处理>大扫灭(有效成
Panax notoginseng has severe continuous cropping obstacle, leading to severe rot of Panax notoginseng, lower yield and lower quality, which severely restricted the development of Panax notoginseng industry. In order to find a soil ecological control method to effectively overcome root rot in the obstacle of Panax notoginseng, researchers from Yunnan Agricultural University compared the effects of eight different soil treatments on the growth and root rot of Panax notoginseng. The results showed that: 8 kinds of soil treatment methods to overcome the continuous cropping obstacles have some effect; the experimental treatment of the emergence rate and survival rate of seedlings, biomass accumulation and reduce the occurrence of root rot comprehensive evaluation, the results were: field steam Treatment> Large-scale destruction (effective into
