麦田小气候因子对粘虫的发生有一定影响。栽培技术及小麦生长情况不同农田小气候特点各有不同,因而影响粘虫发生数量及发育进度的变化很大;禾苗生长愈茂密,小气候相对湿度愈高,温度愈低。此种条件下,粘虫发生数量较大而发育进度较慢。杂草丛生的农田粘虫发生即多,被害严重,这可能也是受小气候因子的影响所致。预测预报时应注意这些规律。 Wheat microclimate factors have a certain impact on armyworm occurrence. Cultivated technology and wheat growth have different characteristics of microclimate on different farmlands, so the quantity and development progress of armyworm affected greatly. The growth of seedlings is more dense and the relative humidity of microclimate is higher and the temperature is lower. Under such conditions, the occurrence of armyworms is larger and the development progress is slower. Weedy farmland armyworms occur more frequently and are severely victimized, possibly due to the effects of microclimate. These rules should be noted when forecasting and forecasting.
