【摘要】 为了筛选出适宜本地区种植的耐瘠冬马铃薯品种,选用省内外9个马铃薯品种,在高垄双行膜下滴灌额定用水量模式下,采用常规基肥用量和减量25%进行重复试验。结果表明:基肥减量对除青薯9号外的品种出苗率影响不大;晚疫病发病率与施肥量无关,部分品种受节肥影响病毒病的发生有加重趋势;节肥后,荷兰14、大西洋株高、茎粗均显著降低,部分品种单株产量下降,但品种间差异各有不同;会-2产量显著提高,青薯9号、毕威1号、夏坡蒂3个品种产量略有增加,其中青薯9号、毕威1号、会-2产量较高,适宜在攀西地区种植。更多还原

【Abstract】 In order to screen out the barren-tolerant winter potato varieties for cultivating in Panxi region, we conducted repeated experiments of nine potato varieties planted on high ridge covered with film and applied with normal dosage or 25 % decrement of base fertilizer under the rated water consumption mode of drip irrigation. Results: base fertilizer saving had little effect on seedling emergence rate of varieties except Qingshu 9; the incidence of late blight was not related to the fertilizer rate, but the occurrence of viral diseases was aggravated by fertilizer saving; after fertilizer saving, the plant height and stem diameter of cultivar Netherlands 14 and Atlantic decreased significantly, the yield per plant of some varieties decreased, and there were differences among varieties; the yield of Hui-2 increased significantly, and the yield of Qingshu 9, Biwei 1 and Charlotte increased slightly, among them, Qingshu 9, Biwei 1 and Hui-2 with higher yield were suitable for cultivating in Panxi region.更多还原
