- 摘要:
- 为在水稻生产中合理使用氮、磷、钾肥，以适合寒地种植的11叶品种空育131为试材，采用“3414”随机区组设计，研究不同的氮、磷、钾配比对水稻生长发育及产量的影响。结果表明：处理6（N2P2K2）、处理10（N2P2K3）和处理11（N3P2K2）可较明显地增加水稻的茎数；合理配施可明显提高水稻的干物质积累，成熟期各处理组合以处理10（N2P2K3)总干重最多，比对照高12.2%；增施氮、磷、钾可增加水稻产量，其中处理11产量和效益最高，产量达10 519.5 kg·hm-2；经回归分析优化出空育131最高产量为12 555 kg·hm-2，相应的氮肥、磷肥和钾肥纯量为135.0,67.5和58.5 kg·hm-2。
- Abstract:
- In order to use nitrogen,phosphorus and potassium fertilizer reasonably in rice production of cold area,taking Kongyu 131 as test material,using randomized block design,the effects of different ratio of nitrogen,phosphorus and potassium on growth and yield of rice were studied.The results showed that treatment 6（N2P2K2）,treatment 10（N2P2K3）and treatment 11（N3P2K2）could increase the rice stem number obviously;reasonable fertilization could increase the dry matter accumulation of rice significantly,total dry weight of treatment 10(N2P2K3)was 12.2%which was higher than the control in mature period;the increasing of nitrogen,phosphorus and potassium could increase the yield of rice,the yield and benefit of treatment 11 were maximum by 10 519.5 kg·hm-2;the highest yield of Kongyu 131 was 12 555 kg·hm-2 by regression analysis,corresponding nitrogenous,phosphate and potash fertilizer scalar were 135,67.5 and 58.5 kg·hm-2。
