本文对影响辣椒幼苗疫病发生的外界因子进行了初步研究。结果表明:在温度低于15 ℃、土壤湿度和空气相对湿度较大的情况下,辣椒疫病的发生加重;空气相对湿度对辣椒幼苗疫病的发生影响比土壤绝对湿度对其的影响更大。此外,土壤偏酸、土质粘重也会加重病情。
In this paper, a preliminary study of the external factors affecting the occurrence of pepper seedling disease was carried out. The results showed that the incidence of pepper blight increased when the temperature was lower than 15 ℃ and the relative humidity of soil and air were relatively high. The effect of air relative humidity on peppery seedling disease was more affected than that of soil absolute humidity. In addition, the soil partial acid, soil sticky weight will aggravate the condition.
