沙地马铃薯滴灌毛管布设试验研究

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0~25 cm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%。

Experimental Study on Capillary Emplacing of Sandland Potatoes

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%.
