1·This indicates that it is one of important reason for wheat yield increase by enhanced harvest index with applying N.
表明施氮提高收获指数是促进小麦增产的主要原因之一。
2·The FUE increased with single applying N and combination applying of P, but the FUE was generally lower in field comparison experiment.
两试验中氮肥单施、磷肥配施的肥料利用率较其它处理的高，大田对比试验中氮、磷肥利用率普遍较低。
3·The effect of applying N-fertilizer or not in wheat on soil fertility and grain yield and fertilizer-N use efficiency (FNUE) of rice in the wheat-rice cropping system were studied.
通过对前茬作物小麦设置施用氮肥与不施用氮肥处理研究它对土壤肥力及后茬作物水稻产量和氮肥利用率的影响。
4·On the basis of applying sufficient amount of n, p, Potassium can improve the quality of farm products.
在氮、磷充足的基础上施用钾肥，能提高农作物品质。
5·Effects of different N-dosage applied and N-applying stages on grain protein content and protein components and yield were studied.
研究了不同施氮量和施氮时期对小麦籽粒蛋白质及组分含量和产量的影响。
6·P had more important effects on corn qualities than K. Compared with CK, long-term N-applying only could improve the corn nutrition, but decrease the flour ash content and starch viscosity.
长期单施氮肥较不施肥的对照（CK）玉米籽粒营养品质有一定的改善，但籽粒粗脂肪含量和淀粉粘度有不同程度的下降。
7·Interaction effect of n, p, K is positive to soybean's growth. According to these characteristics, we can provide theoretical basis for reasonable technology of applying fertilizer.
P、K三要素及元素之间互作对大豆生长均为正效应，由此可为合理施肥提供理论依据。
8·The paper discuses the characteristics and technical problems n applying TP801 microcomputer to sampling and processing the data automatically as the material testing machine.
本文讨论了利用单板微机作为材料力学试验机数据自动采集和处理的特点及技术问题。
