| 摘 要： | 采用"3414"设计方案进行田间试验,探讨施用氮、磷、钾肥用量及其比例对黑龙江省西部、中部和东部地区甜菜产量、含糖率及产糖量的影响。结果表明,肥料施用量以120kg/hm2N、90kg/hm2P2O5、90kg/hm2K2O获得甜菜最高产量和最高产糖量,对甜菜的增产效果为氮>磷>钾,在试验条件下的最佳施用比例为:西部地区1∶0.60∶0.44,中部地区1∶0.41∶0.19,东部地区1∶0.51∶0.48。

| Abstract: | Based on the "3414" fertilizer experiment design,field trials in the western,central and eastern region of Heilongjiang Province were conducted to study the effects of N,P,K fertilizers suitable ratio on yield,sugar content and sugar yield.The results indicated that:Using fertilizer amounts of N、P2O5 and K2O for experiment were 120kg/hm2、90kg/hm2、90kg/hm2 in order to gain the maximum yield and maximum sugar yield and their effects on yield were in order of N>P>K.The results showed that the recommended ratio of N∶P2O5∶K2O were 1∶0.60∶0.44 in the western region,1∶0.41∶0.19 in the central region and 1∶0.51∶0.48 in the eastern region. |
