Wuchang City, Heilongjiang Province, rice flower fragrant rice is famous all over the country, rice is the main planting crop Wuchang, in recent years, with the annual increase in rice production, rice lodging has also increased year by year. Rice lodging generally occurs after heading grain-filling stage and is a result of the combined effects of rice internal factors and external environment. Therefore, in-depth research on lodging resistance in rice is of great significance for realizing high yield, stable yield and high quality of rice. 1 The intrinsic intrinsic factor of rice lodging refers to the lodging resistance of rice cultivars, which is related to plant height, mechanical strength of stalks, toughness of stalks and the length of each internode
