摘要
从秧板载苗量、取秧面积、穴距三因素及其配套角度,研究了机插稻基本苗,提出了机插稻基本苗三因素指标,并通过机插、抛秧、水直播方式的对比分析,明确了机插稻叶面积、茎蘖动态、干物质生产、产量构成等群体质量指标。
The basal seedling number transplanted by machine was studied based on three factors such as seedlings on plate, seedling picking area, spaee between hills and their combination and the indexes for the three factors were pointed out. Through the comparative analysis among transplanting by machine, scattering transplanting and direct sowing, the population quality indexes were clarified in terms of leaf area, tillering trend, dry matter production, and yield components.
