近年来,我省各生态类型区的小麦均有不同程度的青枯发生。为了解小麦青枯的发生与氮磷钾不同配比和土壤质地的关系,本文作者于1984—1987年连续四年进行了这方面的试验研究。尽管四年的气象条件差异较大,但试验结果基本一致,从而对小麦青枯发生的土质及肥料因子有较明确认识,为制定其防御措施提供了一定的科学依据。 In recent years, all ecological types of wheat in our province have different degrees of browning occurred. In order to understand the relationship between the occurrence of wheat withered wheat and the different proportion of NPK and soil texture, the author carried out experimental research in this area for four consecutive years from 1984 to 1987. Although the four-year meteorological conditions are quite different, the experimental results are basically the same, so as to have a clear understanding of the soil quality and fertilizer factors of wheat withered wheat, and provide some scientific basis for formulating the defensive measures.
