甜、糯玉米增温种植效果的研究

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

摘要: 试验研究增温对甜、糯玉米种植效果的结果表明，增温种植育苗+覆膜、育苗比直播种植减产幅度较大，然而由于增温种植提前乳熟收获6～31d，在反季市场价格支持下，早熟、中早熟品种的增温种植比直播提高经济效益4.1%～37.2%，为经济有效地开发甜、糯玉米产业提供了科学依据。

Abstract: 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.
