Abstract

The invention relates to the technical field of crop cultivation, and particularly discloses a high-yield cultivation method for dry land maize. The high-yield cultivation method specifically comprises the steps of seed dressing with a coating agent, soil preparation and base fertilizer application, annular ridge forming, ditch digging, hole digging, fertilizer application and sowing. According to the high-yield cultivation method, seed dressing is carried out through the coating agent, so that seed protection and seed moisture maintaining are achieved, and through a special ridging mode, local water storage in ridges is achieved, water loss is prevented, the water-retaining property is improved, maize seedling emergence and growth are promoted, and the corn yield is increased.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a high-yield cultivation method for dryland corn. Background technique [0002] Drought and water shortage seriously affect the planting of crops. Due to the bare topsoil in dryland planting, serious soil erosion, water and nutrient loss are serious, and the quality of cultivated land is declining day by day, crop yield is low, and the emergence rate is low. The most direct impact of drought on plants is to cause protoplast dehydration, which is the core of drought damage, which can cause a series of damage, resulting in abnormal metabolism of crops, decreased photosynthesis, abnormal water distribution, so that plants are dry and short of water and stunted . [0003] At present, the planting of dryland corn can only pay more attention to irrigation, while ignoring water retention and preventing water loss, resulting in serious waste of water resources, ignoring the eff...
