二化螟(Chilo supprassalis walker)是台江县水稻主要害虫之一。研究二化螟田间枯心苗的分布型,无论是在二化螟幼虫生态研究上,还是在测报和防治技术研究上都有重要的意义。一方面它可以揭示出枯心苗的田间结构及其田间图式的特征,另一方面它又是确定抽样技术和资料代换的基础。 Chilo supprassalis walker is one of the major rice pests in Taijiang County. Studying the distribution pattern of dry seedling in the field of rice stem borer, both in the ecological research of the larvae of the stem borer, or in the measurement and prevention and control technology are of great significance. On the one hand, it can reveal the field structure of dry seedlings and the characteristics of their field patterns. On the other hand, it is also the basis for determining sampling techniques and data substitution.
