您要查找的是不是:
- equal nitrogen fertilization 等氮量施肥
- The nitrate form commonly dominates where liberal nitrogen fertilization is practiced. 施用足量氮肥的土壤,通常硝酸钙占优势。
- Nitrogen fertilization with DCD could mitigate N_2O emission, and have no significant effect on CH4 uptake rate. 在施肥处理中,添加DCD的尿素和碳铵处理能减少N_2O排放通量,同属于铵态氮肥的碳铵和尿素对旱地农田CH_4吸收的抑制作用没有显著差异。
- Only keeping suitable SWC after anthesis and nitrogen fertilization can benefit the improvement of Amylopectin to Amylose ratio. 只有保持适宜的花后土壤含水量和施适宜的氮肥才有利于支/直比的提高。
- Consequently, proper enhancement in nitrogen fertilization or suitable SWC improved the processing quality of wheat grain. 适量增施氮肥或花后土壤含水量适宜可提高小麦的加工品质。

- The frequency with which farmers can expect a legume yield increase from nitrogen fertilization is low for most species (Table 8). 对大多数种来说,农民们可以期望通过施用氮肥来使豆类作物增产的概率是不大的(表8)。

- A field experiment was conducted in 1999 to investigate differences of adaxial and abaxial surface reflectance of rice leaves under 5 levels of nitrogen fertilization. 在田间条件下测定了5个氮素水平处理的水稻叶片在分蘖、孕穗和抽穗期的上表面反射率和下表面反射率。

- Should nitrogen fertilizer be applied after injected swine manure? 如何树立种猪引入的科学理念?
- It is obvious that successful producers have surmounted nitrogen fertilization challenges because there is less demand for research on that topic than existed earlier. 很明显,成功的生产者已解决了氮肥施用问题,因为比以前,这个问题已不需要那么多研究了。
- The sulfur nutrient was significantly affected by fertilization system.The nitrogen fertilization could improve the quantities of ammonification bacteria in soil. 硫化细菌和反硫化细菌数量与土壤有机质含量无直接相关性,施肥可影响土壤硫素的供应。
- Excessive application of nitrogen fertilizers results in tardy bearing. 施用过量的氮肥结果使树延迟结果。
- These plants need no nitrogen fertilizers and leave the soil rich in nitrogen. 这样的植物不需要施用氮肥,并且还给土壤留下了丰富的氮。
