1·Soil microbial biomass N also involved in nitrogen supply to crop.

土壤中微生物氮也参与了对作物的供氮过程。

2·Nitrogen supply largely controls the growth and fruiting of most plants.

氮的供应密切地关系到绝大多数植物的生长与结果。

3·With the increase of nitrogen supply, the content of carbohydrate decreased.

随供氮量的增加，碳水化合物含量相对减少。

4·When the nitrogen supply was not enough, it was main limiting factor of vegetable yield.

在氮供应不足的条件下，氮素是蔬菜产量的限制因子。

5·And the results suggested: Machurian Ash seedling leaf nitrogen content is linearly relative to the nitrogen supply levels.

水曲柳幼苗苗叶片氮含量与供氮水平呈线性相关。

6·We further demonstrated that a high grain yield can be obtained with SHAN-YOU 63 cultivated under low or middle nitrogen supply levels.

试验结果表明，沿优63的增产潜力显著大于汕优6号，但需氮量却比汕优6号要低。

7·Nitrogen supply level and its interaction with FACE had less effect on the phosphorus nutrition of rice at its different growth stages.

氮处理以及氮与FACE处理的互作对水稻不同生育时期的磷素营养影响较小。

8·So it is the key section to solve the agricultural production issues that using the different ways in the regulation of nitrogen supply.

因此，农田生产中采用不同方式调控氮素供应，是解决上述问题的关键。

9·The result also sbowed that glucose and mannose are excellent resource for carbon and yeast extract and peptone are suitable for nitrogen supply.

适宜碳源为葡萄糖、甘露糖； 适宜氮源为酵母膏和蛋白胨。

10·Sufficient nitrogen supply during grain filling period promoted kernel growth by improving carbon-nitrogen metabolism and sink activity of kernels.

整个灌浆期氮素供应充足提高了籽粒库活性和碳氮代谢水平，促进了籽粒库容建成和库充实；
