| 摘 要： | 为明确迷你型紫甘薯早收栽培和延长其生育期、在正常收获期收获的适宜扦插密度,采用2个收获期,7个扦插密度处理,比较鲜食迷你型紫甘薯不同收获期扦插密度对产量的影响。结果显示,扦插后第89天收获的扦插密度以67 500株/hm^2为宜,如果延长其收获期至11月10日,则以45 000株/hm^2的扦插密度产量最高,且极显著地高于其他各处理。

| Abstract: | To study the planting density affect yield of mini purple sweet potatoes at different harvest time,a test was made by extending its growth period and adopting different planting density.Also the planting densities were 30000,37500,45000,52500,60000,67500 and 75000 plants/hm^2.The results showed that the planting density of 67500 plants/hm^2 was appropriate with a growth period of 89 days after planting while the harvest period was extended to 10 November,the planting density of 45000 plants/hm^2 had the highest output and significantly higher than that of other treatments. |
