Abstract

The invention discloses a novel technology for high-yield cultivation of drought resistance maize in the yellow river delta region. The production capacity of salination soil in the yellow river delta region is improved, the grain yield is improved, implementation of science and technology demonstration engineering of a grain elevator in the Bohai Sea is promoted, and the food security in China is ensured. On the basis of characteristics of salination soil in the yellow river delta region, hydrological climate and other national conditions, scientific irrigation, straw salt restraining, biological organic fertilizer salt modification and alkali restraining, deep ploughing seeding, nitrogen fertilizer postponing, the stress resistance and yield increasing technology through alga active substances, microelement scientific matching technology are integrated, and the systematized yellow river delta high-quality maize yield increasing cultivation technology system capable of achieving rolling reproduction is constructed, biogas slurry is creatively used for maize grain yield increasing irrigation, straw coverage is adopted for salt restraining and alkali modification, water for irrigation is saved, and the water saving effect is remarkable.

Description

technical field [0001] The invention relates to a new technology for high-yield cultivation of drought-resistant corn in the Yellow River Delta region, in particular to a high-quality cultivation technology for high-quality corn in saline-alkali land in the Yellow River Delta, and belongs to the technical field of crop production. Background technique [0002] The Yellow River Delta is a new land formed by the Yellow River land-building movement in the past century, with an area of ​​442,900 hm of salinized land 2 , accounting for the total area of ​​the [0003] More than half, and with the development of irrigated agriculture, the area will continue to expand, which seriously affects the grain output and becomes the main factor restricting the development of agricultural production. At present, maize is one of the main crops cultivated in saline soil in the Yellow River Delta. Due to the influence of the monsoon climate, the salinity of the cultivated layer in the saline...
