- 摘要:
- 为促进马铃薯产业的可持续发展，研究了延薯6号品种在吉林省地区不同密度下对产量及经济效益的影响。结果表明：68 400株?hm-2为吉林省地区种植延薯6号的最佳种植密度，平均单产37 480.5 kg?hm-2，比对照增产2 380.5 kg?hm-2；商品率达到77.9%，比对照提高1.9%；经济效益达到21 345元?hm-2，比对照增加1 440元?hm-2。
- Abstract:
- In order to promote the sustainable development of potato industry，the effect of different planting density on yield and economic benefit of Yanshu 6 potato in Jilin province was investigated.The results showed that the best planting density was 68 400 plant?hm-2;the average yield was 37 480.5 kg?hm-2，and 2 380.5 kg?hm-2?higher than the control group; the commodity rate was 77.9%,and 1.9 percent point higher than the control group; it gained 21 345 yuan?hm-2,and increased 1 440 yuan?hm-2?by the control group.
