- 摘要:
- 为进一步提高甜菜生产水平,为高产施肥提供技术支撑,在黑龙江省黑土和白浆土甜菜主产区,采用3×3优化施肥设计开展甜菜优化施肥研究。结果表明:黑龙江省甜菜高产施肥中氮和钾的适宜用量为90~135 kg·hm-2,磷的适宜用量为80~120 kg·hm-2,氮磷钾的适宜比例为N∶P2O5∶K2O=1.13∶1.00∶1.69。不施氮肥平均减产33.8%,不施磷肥平均减产21.1%,不施钾肥平均减产21.6%。从产量上看,最佳处理为N2P2K3,即N 90 kg·hm-2、P2O 80 kg·hm-2、K2O 135 kg.hm-2,较对照平均增产31.9%。
- Abstract:
- In order to improve the sugarbeet production level and to supply fertilization technology support for gaining high yield,the 3×3 optimized fertilization design was adopted to study sugarbeet fertilization in the main sugarbeet production of Heilongjiang province.The results showed that the optimum rate of nitrogen and potassium for high yield sugarbeet was 90~135 kg·hm-2,phosphorus was 80~120 kg·hm-2;The optimum ratio of nitrogen,phosphorus and potassium was N:P2O5:K2O=1.13:1.00:1.69.Without nitrogen,phosphorus and potassium application,the yield decreased by 33.8%,21.1% and 21.6%,respectively.On the consideration of the yield,the best treatment was N2P2K3,that was N 90 kg·hm-2,P2O5 80 kg·hm-2,K2O 135 kg·hm-2,which yield increased by 31.9% compared to CK.The study established three type fertilization models of high yield sugarbeet production in the three kinds of soil and different ecological type.
