| 摘 要： | 试验采用311-A饱和设计．建立了灌水定额、氮肥和磷肥对燕麦产量的数学模型．并对燕麦成熟期粗灰分、粗蛋白、全N、全P、全K、单株叶面积和产量进行测定，研究N、P和水分与产量的耦合效应及成熟期植株粗灰分、粗蛋白、全N、全P、全K、单株叶面积与产量的相关关系。结果表明：其相关顺序为：叶面积〉全K〉全N〉全P〉粗灰分〉粗蛋白，叶面积与产量呈显著相关。通过研究N、P、水对植物产量的影响，可以得出在N200kg／hm^2,P102kg／hm^2水800mm的配比条件下达到最高产量。

| Abstract: | Out the use of.311-A saturated Design,which is the establishment of a Irrigation Quota, nitrogen and phosphate fertilizer production of oats on the mathematical model, and crude ash,crude protein,total-N,total-P,total-K,plant leaf area and yield in the mature of Oat were determined,research on N ,P and water production coupled with the effects of mature plants and coarse ash,crude protein,total-N,total-P,total-K,plant leaf area and the correlation between production. The results showed that： its relevance for the order： plant leaf area〉total K〉total N〉total P〉coarse ash〉crude protein, plant leaf area and yield were significantly related.Through the study of N,P,water production plant, can be drawn that： N： 200kg/hm^2, P：102kg/ bin^2, water800mm proportion of the conditions to achieve maximum production. |
