| 中文摘要: |
| 采用正交旋转组合设计试验研究了节水麦田N、P2O5、K2O施用量与小麦产量、经济效益及成本的关系。结果表明,增施氮磷肥是小麦高产高效优化栽培的关键,合理的配比施肥量为每公顷施纯N 259.26~318.84 kg,P2O5121.52~154.61 kg,K2O 71.42~130.22 kg,并对不同条件下的肥料配比和施肥量进行了经济技术分析。 |
| 英文摘要: |
| The interrelationships between the 3 fertilizer factors （ N，P2O5 and K2O） and the yield， economic benefit and cost of saving-water wheat were studied by the experiment design of orthogonal rotation combination．The results showed that to increase the application rate of nitrogen and phosphorous fertilizers was the key measurement in the high-production and high-efficiency optimal cultivation of winter wheat．The reasonable fertilization combination was N 259．26～318．84kg／hm2，P2O5121．52～154．61kg／hm2，and K2O 71．42～130．22kg／hm2．Moreover，the fertilization prescription and amount in connection with different conditions was analyzed from the aspect of economy and technology． |
