Reasons and coping strategies for the formation of poorly sturdy corn cob and multiple ears
Based on the practical production and cultivation,the reasons for the formation of poorly sturdy corn cob and multiple ears were summarized and analyzed by referring to relevant literature,corresponding countermeasures were proposed,and the research direction was prospected.The main reasons for the formation of poorly sturdy corn cob and multiple ears included genetic factors of the variety,external environmental factors(high temperature and drought,cloudy and rainy),and cultivation management factors(sowing date,density,pest control,disease and insect pests,and pesticide application).By selecting stress resistant varieties,and carrying out field management such as reasonable fertilization,timely weeding,soil loosening,and timely watering,the stress resistance of corn can be improved,and poor ear development caused by improper management can be avoided.The next step of research will utilize modern technologies such as gene editing to analyze the mechanism of poorly sturdy corn cob and multiple ears formation;explore new agronomic measures such as foliar fertilization to improve maize yield and quality.This paper provides references for improving corn yield and promoting the healthy development of related industries.
