鲜食玉米不同栽培方式的生理特征及产量效应

选用渝糯7号为材料，研究湘南地区不同育苗、移栽、覆盖方式等栽培技术措施对鲜食玉米生理特征和产量的影响。结果表明，鲜食糯玉米春播在3月25日左右播种，采用育苗移栽和地膜覆盖栽培等技术，可提高根际土壤含水量、根际土壤温度及干物质积累量；根系活力、叶片光合势和叶绿素含量有不同程度增加，最终获得较高鲜穗产量。

The Physiological Characteristics and Yield Effect of Fresh Corn Under Different Cultivation Methods

Yu waxy corn No.7 was chosen as the experimental material to study the physiological characteristics and effect on yield under different cultivation techniques and measures, such as cultivating seedlings, transplanting and covering etc., the research result showed that the planting of fresh waxy corn in early spring should be seeded on March 25th or so in South Hunan area. Adopted the technologies of transplanting of cultivating seedlings, covering ground film cultivation and so on. Soil moisture, rhizosphere soil temperature and dry matter amount could be increased. Root system vigor, LAD and chlorophyll content could be increased to different degrees, eventually obtained a higher yield of fresh ear.
