您要查找的是不是：
- It would appear (Table 2.) that the 1995 predicted needs could be met immediately by applying the known technology of balanced NPK fertilization. 从表2看来，应用已知的平衡施肥（NPK）技术现在就可达到1995年的需求量。
- Crop yield was remarkably increased under NP or NPK fertilization,but N surplus still remain at a lower level even though N uptake improved. 硝态氮累积量高且大部分集中在根区外土壤,硝态氮淋失风险大。
- Balanced NPK fertilization offers a well known and relatively easy technology for increasing crop production rapidly in China. However, this is not the only technology available. 氮磷钾平衡施肥为中国尽快增加粮食产量提供了一项人所共识、相对易行的技术。当然，这不是唯一可行的技术。
- It is important, however, to focus more attention upon balanced NPK fertilization for China because this offers one of the quickest and most economical ways of increasing yields. 更加重视氮磷钾平衡施肥对中国至关重要，因为这可为增产提供一条迅速而经济的捷径。
- Results showed that long term application of NPK fertilizers or manure could increase soil biomass-N, especially the effect of manure on biomass-N was obvious. 结果表明,长期施用有机肥或化肥均能增加土壤生物量氮数量,尤以有机肥的作用明显。
- EFFECT OF NPK FERTILIZATION ON THE YIELD OF ALOE 氮磷钾肥对芦荟产量的影响
- The experimental results showed that base NPK fertilizer has double effect to increase resources and to expand sink. 结果表明,关中棉区抗虫棉施K及K与np配施具有增源扩库的双重效应,促进早熟,增产显著。
- The results show that no significant difference was observed in composition of weed communities between plots receiving balanced NPK fertilization of organic manure or chemical fertilizer. 结果表明：N、P、K平衡施用时，无论是施用有机肥，或是施用无机化肥，田间杂草的种群组成相似；
- In addition, the structure of ammoniatorgranulator and the operation condition for MAP, DAP and NPK fertilizers production are explained. 同时阐述了转鼓氨化造粒机的构造以及用于生产MAP、DAP和NPK复合肥的条件。
- The analysis to pollution criterion of NPK fertilizer plant shows that the current standards cannot cover all the limitation of pollutant discharges. 对NPK复合肥工厂污染物排放标准的分析表明:现行的有关标准不能涵盖其污染物排放的限制。
- Some plants push their roots deep into the soil. 一些植物的根深深长入土中。
- Such crops won't grow in limy soil. 这类作物不能在石灰质的土壤中生长。

- There are a lot of worms in the soil. 泥土中有许多蠕虫。
- Water has permeated (through) the soil. 水已渗遍那片土壤。
- There are some clods of soil on the mat. 垫子上有些土块。
- The earth in the garden is good, soft soil. 花园里的泥土松软肥沃。
- This kind of soil contains much alkali. 这种土壤含碱丰富。
- She makes her living from the soil. 她以务农为生。
- Grass will not succeeded in this dry soil. 在这种干燥土壤中草不会成活。
