【摘要】 宁夏固原马铃薯优势种植区由于常年使用传统犁耕和旋耕机械,引起土壤板结、犁底层变厚、耕层变浅、土壤保墒蓄水能力降低和土壤养分流失,使得马铃薯单产水平低,产量逐年下降。本试验采用传统旋耕(耕作深度15cm)为对照,粉垄耕作(耕作深度30～50 cm)为研究对象,探究粉垄耕作对马铃薯品质和产量的影响。结果表明:较传统旋耕,当年粉垄和去年粉垄马铃薯单株薯质量分别提高29.52%和11.00%,烂薯率分别减小0.10%和2.46%,产量分别增加12.90%和28.32%。因此,粉垄耕作可提升马铃薯品质和产量,在宁夏马铃薯种植上有一定的推广价值。更多还原

【Abstract】 In the dominant potato planting area of Guyuan in Ningxia, the phenomena of soil hardening, severe plough bottom, plough layer shallowing, soil moisture retention ability reducing and soil nutrient loss were the result of using traditional soil tillage machine of ploughing and rotary tillage all the year round. Furthermore, the potato yield per unit area was low and yield was decreasing year by year. In this experiment, traditional rotary tillage(tillage depth of 15 cm) was used as the contrast and smash-ridging(tillage depth of 30～50 cm) was used as the research object for investigating the effect of the using of smash-ridging cultivation on potato quality and yield. The results showed that compared with traditional rotary tillage, the potato quality of single plant by smash-ridging cultivation in this year and last year was increased by 29.52%and 11.00% respectively, the rotten potato rate was decreased by 0.10% and 2.46% respectively, and the yield was increased by 12.90% and 28.32% respectively.Therefore, the smash-ridging cultivation of can improve the quality and yield of potato, which has certain promotion value in potato planting in Ningxia, and can effectively promote the development of potato industry in Ningxia.更多还原
