通常混种或间种比清种产量高。荷兰的大量试验证实,早熟种和晚熟种混种能增加块茎的产量。在本篇报告的试验中,将各种类型的马铃薯成对混种,与清种进行比较,以评价不同生长类型种薯混种而可能提高的产量增益。各生长类型可通过选择品种或种薯处理得到。
Usually mixed or inter-species than the high yield. Numerous experiments in the Netherlands have confirmed that the combination of precocious and late-maturing species can increase tuber yield. In the trials reported in this report, various types of potatoes were mixed in pairs to compare with clear species to evaluate the potential yield gains of mixed seed types with different growth types. Each growth type can be selected by species or seed treatment.
