摘 要:为探讨水城县马铃薯高产栽培技术,本研究以水城县种植较广的4个马铃薯品种(系)及近年来贵州省马铃薯区域试验六盘水试点表现较优的4个品种(已审定)进行品比试验。结果表明,产量最高的是宣薯2号,抗性最好的是水城县本地品种(系)"水城本地乌";另以宣薯2号为试验品种,对水城县山区马铃薯种植的适宜密度、施肥配比及覆膜方式等做了相关探索,通过2 800穴/667m^2、3 300穴/667m^2、3 800穴/667m^2、4 300穴/667m^2、4 800穴/667m^2等5个密度梯度的随机区组试验,得出密度为3 800穴/667m^2的产量最高;通过3414肥效试验,得出当施肥量及配比为氮肥(含N 46%)21.74kg/667m^2、磷肥(含P2O2 50%)79.69kg/667m^2、钾肥(含K2O 50%)32kg/667m^2时,达到最高产量;通过覆膜方式的试验,发现所有覆膜方式都相对不覆膜增产,其中播种时覆黑色膜最高增产527.54kg/667m^2。In this study,four potato accessions recent audited by Guizhou province and wild planted in Shuicheng county,Liupanshui city,were used for comparison experiment of varieties,meanwhile,several tests had carried out to investigation the desire density,the ration of fertilizer and film information was conducted by using Xuanshu No.2 as test material.The result indicated that the highest production of potato accessions was Xuanshu No.2,and Xuanshu No.2 had the best disease resistance ability;by 2800 cells/667 m^2,3300 cells/667 m^2,3800 cells/667 m^2,4300 cells/667 m^2,4800 cells/667 m^2 five acre density gradient randomized block experiment,the highest yield was obtained with 3800 cells/667 m^2;by 3414 fertilizer experiment,obtained when the amount of fertilizer and ratio:the amount of fertilizer:nitrogen(containing N 46%)per acre 21.74 kg,phosphate(including P 2O 250%)per acre-79.69 kg,potash(including K 2O 50%)when 32 kg/667 m^2,the highest yield was obtained;the Film Mulching experimental showed that the yield of potato was higher than that did not Film Mulching by all Film Mulching methods,while the highest yield was obtained by black Film Mulching,with 527.54 kg/667 m^2.
