摘 要:在陕西省靖边县进行大田马铃薯滴灌毛管布设方式试验,初步研究了几种滴灌毛管布设方式对马铃薯生长及地温的影响。结果表明:一带一行毛管布设方式下马铃薯地上部分及根系的生长最好,一带二行与二带三行差异不大;二带三行毛管布设方式对0~25cm地温降低效果最显著,为马铃薯块茎发育提供相对优越的凉爽环境;3种毛管布设方式下马铃薯单株产量一带一行〉一带二行〉二带三行。平均单产二带三行〉一带二行〉一带一行;二带三行在保持商品薯率基本不变的前提下单产比一带一行增产52%,经济效益提高100%。Through the experimentation of potato drip capillary emplacing manner's preliminary study on potato growth and soil temperature effects in Jingbian county, Shaanxi province. We get that: one belt one row has the best growth, and the one belts two rows has little difference from two belts three rows; two belts three rows has the most significant cooling effect of 0 to 25 centimeter soil layer, this providing a relatively favorable environment for potato tubers' development. Three potato yields of capillary emplacing,per plant one belt one row〉one belt two rows〉two belts three rows, with an average per-mu yield two belts three rows〉one belt two rows〉one belt one row; two belts three rows in keeping with the commodity rate unchanged and the yield still increase 52% than one belt one row, it's economic performance has proved 100%.
