| 摘 要： | 以特用型马铃薯品种"东农306"为材料,在2003～2004年进行了种植密度与钾肥用量对产量的影响试验。结果表明,该品种在不同种植密度与钾肥用量下单株产量差异显著,在本试验中以行距70 cm和株距30 cm的密度、硫酸钾用量150 kg·hm~(-2)最适合该品种的个体生长,能获得较高的单株产量和商品薯产量;行距70 cm和株距20 cm的密度、硫酸钾用量75 kg·hm~(-2)最适合该品种的群体生长,能获得较高的群体产量和商品薯产量。

| Abstract: | The special purposed potato variety NEA306 was planted in Harbin under several treatments of planting density and potash fertilizer in 2003 and 2004.Significant difference was found in yield per plant at different treatments of planting densities and potash fertilizer regimes.High total tuber yield and marketable tuber yield per plant were reached when potatoes were planted at 70 cm between rows and 30 cm within the row and potassium sulphate was applied at the rate of 150 kg per hectare.However,on the basis of plot,high total tuber yield and marketable tuber yield could be harvested when potatoes were grown at 70 cm between rows,but 20 cm within the row,and still potassium sulphate was banded at the same,150 kg per hectare. |
