摘要
为研究马铃薯专用肥对马铃薯植株株高、主茎数、结薯个数、薯块产量以及商品薯率的影响,2017~2018年马铃薯生长季,以当地马铃薯品种‘荷兰15号’为试验材料,以不施肥为对照(CK),评价马铃薯专用肥(JS)和普通农用复合肥(PT)两个施肥处理。结果显示,与CK相比,JS处理可提高马铃薯的株高、主茎数和结薯个数,分别为7.62%、15.00%和44.48%;与PT相比,提高2.33%、9.55%和14.77%。JS处理产值较CK提高142.29%,较PT提高33.55%。JS较CK增收17481元/hm^2,较PT增收10080元/hm^2。在试验条件下,施用马铃薯专用肥可明显改善马铃薯植株的农艺性状,提高马铃薯的产量和薯块商品薯率,达到增产增收的效果,值得推广与应用。
The objectives of this study were to evaluate the effects of potato special fertilizer on plant height,number of main stems,number of tubers,yields of tuber and marketable tuber percentage of potato('Netherlands 15').Two fertilizer treatments,potato special fertilizer(JS)and regular agricultural compound fertilizer(PT),were evaluated using no fertilization as a control during the growth seasons from 2017 to 2018.The plant height,number of main stems and number of tubers under JS treatment were increased by 7.62%,15.00%and 44.48%,respectively,compared with control,and by 2.33%,9.55%and 14.77%,respectively,compared with PT.The output value of JS treatment was 142.29%higher than that of the control,and 33.55%higher than that of PT.The income of JS treatment was increased by 17481 Yuan/ha compared with CK,and by 10080 Yuan/ha compared with PT.Based on these results,the application of special fertilizer could improve the agronomic characters,yield and marketable tuber percentage of potato,achieving the target of increasing production and income,and therefore being worthy of promotion and application.
