摘要: 冀张薯8号为北方一季作区主栽马铃薯(Solanum tuberosum L.)鲜食品种,因其高产抗逆广受薯农欢迎。但其生育期长,收获时植株浓绿,马铃薯脐部脆嫩,往往造成病菌侵染,导致库存烂薯严重。为了提高冀张薯8号的耐储性,增加其经济效益,在河北省张家口市坝上地区,以不杀秧为对照,研究了机械杀秧、3种浓度立收谷杀秧对冀张薯8号产量和耐储性的影响。结果表明,低浓度(3.0 g/L)立收谷杀秧经济效益最好,增加了1 409元/hm2;此杀秧田间产量为40 530 kg/hm2,比对照产量(40 800 kg/hm2)减产0.7%;烂薯率为2.5%,比对照烂薯率(4.7%)明显降低;出库好薯重为39 517 kg/hm2,比对照(38 882 kg/hm2)增产1.6%;淀粉含量为13.99%,比对照降低了1.00个百分点;干物质含量为19.45%,比对照降低了1.31个百分点。

Abstract: Jizhangshu No.8 is the main cultivated fresh food potato (Solanum tuberosum L.) variety for a seasonin the northern , and it is popular with potato farmers because of its high yield and stress resistance. But its growth period is long, the plant is thick green when harvest, potato navel is crisp and tender, making it often cause pathogen infection, cause stock rotten potato to be serious. In order to improve the storage resistance of Jizhangshu No.8 and increase its economic benefit, the effects of mechanical seedling killing and three concentrations of Lishougu seeding killing agent on the yield and storage resistance of Jizhangshu No.8 were studied in the Bashang area of Zhangjiakou city in Hebei peovince without seedling killing as the control. The results showed that low concentration (3.0 g/L) Lishougu seeding killing agent had the best economic benefit and increased 1 409 yuan(RMB)/hm2, field yield of this treatment was 40 530 kg/hm2,0.7% less than that of control (40 800 kg/hm2); The rate of rotten potato was 2.5%, which was significantly lower than that of control (4.7%), and the weight of good potato out of storage was 39 517 kg/hm2, which increased 1.6% compared with that of control (38 882 kg/hm2);the starch content was 13.99%, decreased by 1.00 percent, and dry matter content was 19.45%, decreased by 1.31 percent.
