Study on elevated-temperature planting technique in sweet and glutinous corn

The results of the experiment on the effects of elevated-temperature planting techniques on sweet and glutinous corn show that though the techniques of growing seedling under plastic film mulching or seedling transplant reduces corn yield in comparison with direct sowing, their economic benefits are 4.1%～37.2% greater than direct sowing due to a 6～31-day earlier harvesting.
