摘要
在定西市干旱条件下,采用随机区组设计,研究‘定薯1号’种植密度对农艺形状和产量的影响。结果表明,不同密度对‘定薯1号’出苗期和开花期的影响不大,而对株高、主茎分枝数、茎粗、封垄时间、成熟期等方面的影响较大;‘定薯1号’宽窄行种植时,最佳密度为64935株/hm2,产量达26250kg/hm2,适宜种植密度为64935～69630株/hm2;单行种植时,播种密度为54945株/hm2的产量最高,为17437kg/hm2,适宜的密度范围是51020～54924株/hm2。
Under drought conditions in Dingxi, using randomized block design, the influences of planting density of‘Dingshu no.1＇ on potato shape and yield was studied. The results show that the density have little effect on potato seedling and flowering period, yet it had great effects on the plant height, main stem branch number, stem diameter, ridge closure time, maturity, etc. If using wide and narrow row planting method, the best density of ‘Dingshu no.1＇ was 64 935/hm2 with the yield up to 26 250 kg/hm2, and the suitable planting density range was 64 935 - 69 630/hm2. Adopting single row planting method, the best density was 54, 975/hm2 with yield of 17 437 kg/hm2, and the appropriate density range was 51 020 - 54 924/hm2.
