以东北山区常见的12种农作物为受体,研究了老参地土壤水溶性物质对其生长发育的影响,探讨参地土壤的化感作用及适宜的农田参粮、参菜轮作植物。结果表明:参土水提液对受体植物的作用主要通过影响其萌发率和幼根生长实现,主要存在4种作用类型,即促进、抑制、低促高抑、低抑高促;不同受体植物对参地土壤水溶性化感物质的敏感性不同,苦苣和茄子最敏感;12种受试植物中,除黄瓜、茄子、番茄外,其余植物均可作为老参地的后茬植物。
In this paper, the effects of soil water-soluble substances on the growth and development of old ginseng soils were studied using 12 common crops in northeastern mountainous areas. The results showed that the effect of water extract of Ginseng on the recipient plants mainly through the influence of the germination rate and the growth of young roots. There are mainly four types of action, namely, promotion, inhibition, low and high inhibition, low and high promotion; The sensitivities of somatic plants to soil water-soluble allelochemicals were different, while that of borage and eggplant was the most sensitive. Except for cucumber, eggplant and tomato, the rest of the 12 tested plants could be used as the stubble plants .
