摘  要:
[目的]研究柴达木地区青薯2号马铃薯高产优质的密度,及氮肥、磷肥、钾肥施用量的最优组合。[方法]在柴达木地区利用4因素二次通用旋转组合设计,试验青薯2号马铃薯的密度、施氮量、施磷量、施钾量与其块茎产量、淀粉含量、商品薯含量、淀粉产量的回归关系。[结果]结果表明:在柴达木地区,青薯2号块茎产量、淀粉产量最高的最优组合为密度6.75×104粒/hm2、纯氮125.00 kg/hm2、P2O5120.00 kg/hm2、K2O 250.00 kg/hm2;商品薯产量最高的最优组合为密度6.75×104粒/hm2、纯氮199.32 kg/hm2、P2O595.67 kg/hm2、氧化钾199.32 kg/hm2。[结论]在柴达木地区,青薯2号的块茎产量、淀粉含量、商品薯产量、淀粉产量与密度、施氮量、施磷量、施钾量之间有极显著的回归关系。

摘  要:
[Objective]The research aimed to select the optimal planting density and optimal combination of N,P and K fertilizer application.[Method]Regressive experiment method of orthogonal conic substitution with four factors was applied to analysize relationships between planting density,N,P,K fertilizer application and the yield of tuber,the potato yield for sale,the yield of starch on potato Qingshu 2 in Chaidamu area.[Result]The best combination with highest yield of tuber and starch was density 6.75×104 grain/hm2 and N,P2O5,K2O application amount at the rate of 125.00 kg/hm2,120.00 kg/hm2 and 250.00 kg/hm2,respectively.And the best combination with highest potato yield for sale was density 6.75×104 grain/hm2,N,P2O5,K2O application amount at the rate of 6.75×104 grain/hm2,199.32 kg/hm2,95.67 kg/hm2 and 199.32 kg/hm2,respectively.[Conclusion]The regression relationships between planting density,N,P,K fertilizer application and the yield of tuber,the potato yield for sale,the yield of starch on potato Qingshu 2 in Chaidamu area was very significant.
