Abstract

Abstract: To reduce lodging rate and moisture without reducing density, and increase the yield of maize, maize three-space cultivation pattern is studied. Maize three-space cultivation pattern is the integration of space in ridges, space in the top of the maize field by cutting off stalk above the corn ear and space crosswise the field perpendicular to ridge direction. The results indicated that the three- space cultivation pattern included, the number of ridges without culture: the number of ridges with culture =2:12, the number of ridges with cutting stalk: the number of ridges without cutting stalk =2:4, the length of space crosswise the field vertically was 2 m per 500 m when the length of ridges was greater than 1000 m. With the above cultivation pattern, the lodging rate of maize was reduced by 11%, grain moisture was reduced by 9%, and the yield of maize was increased by 20.32%. Maize three-space cultivation pattern could significantly reduce the lodging rate and grain moisture of maize, and increase the yield of maize. Maize three-space cultivation pattern is suitable for maize production in Heilongjiang Province.
