摘要
在浙江省马铃薯主产区丽水市,通过2年试验,研究了东农303马铃薯施肥措施对产量及相关性状的影响。结果表明:在当地习惯施肥(N80kg·hm-2、农家肥104kg·hm-2)基础上,提高氮肥量至120kg·hm-2同时增施磷肥、钾肥,提高了马铃薯产量、淀粉含量和商品率,提高了叶面积系数、叶绿素含量和净同化率。同时试验结果表明:增施磷钾肥不同处理效果不同,磷钾肥配合增施较单纯增施效果明显,其中以N120kg·hm-2、P2O580kg·hm-2、K2O170kg·hm-2、农家肥104kg·hm-2的施用量效果最佳。
After two years＂ experiments in Lishui, the main potato producing area of Zhejiang, the effects of fertilization measures of high production of Dong Nong 303 potato on its production and related traits are examined. The result of the tests indicates that the potato production, the starch content and the commodity rate can be improved as well as leaf area index, chlorophyll content; net assimilation rate and solids content can be increased by increasing the amount of nitrogenous fertilizer to 120 kg·hm^-2 and increasing the phosphate fertilizer and potassium fertilizer on the basis of the usual fertilization in local area （N 80 kg·hm^-2, farmyard manure- 10 kg·hm^-2）. In the meanwhile, the result of the tests shows that different disposal methods of phosphate and potassium fertilizer lead to different production effects：the effect of increasing of both phosphate fertilizer and potassium fertilizer are more obvious than one single fertilizer;, and we can receive the best effects by a proportioning of N 120 kg·hm^-2, P205 80 kg·hm^-2, K2O 170 kg·hm^-2.
