查询词典 field corn

There isn"t obvious selectivity in blank cutworm imperilment, the onseting quantity and imperilling degree is similar on different crops. It"s more serious in the field of invasion of weeds and corn intercrop potato than single cropping of corn, and the field of forecrop green manure is more serious than single cropping. Imperilment degree of black cutworm is very serious in both high altitude region as Dewu (1780 meters) and low altitude region as Lemin (1450 meters). The imperilment degree in two regions have no obvious differences. 4. The imperilment of second generation armyworm is very serious in both high altitude region of Dewu and low altitude of Lemen town.
