The dissolved curves of nitrogen and potassium of B2,PS,F2,F2F in same soil column were similar to that of in sand column, and difference was only dissolved time. The peak time of phosphorus was later than that of nitrogen and potassium.

四种胶结包膜型缓/控释肥料在同一土壤柱里氮钾素溶出曲线与其在砂柱里的近似，只是溶出时间不同，磷素溶出高峰期比氮钾素延后。B2、PS、F2、F2F之间的差别与其砂柱里的情况相同。

China is now the world's leading consumer of wheat, rice, meat, coal, fertilizers, steel, and cement, and it is second largest consumer of oil after the United States.

中国现下是世界小麦，大米，肉，煤，肥料，钢和水泥的主要消费者，并且这在美国之后是油的第二大的消费者。

A diffusion experiment and pot trial were conducted to evaluate the effect of acidic rhizosphere fertilizer on the soil pH and Fe availability and the growth, iron deficiency correction of peanut on calcareous soil.

在无植物栽培的条件下通过肥料在土壤中的扩散试验研究酸性根际肥对石灰性土壤 pH值、有效铁含量的影响，利用盆栽试验验证对石灰性土壤上花生缺铁失绿黄化症的矫正效果。

Inwheat intercropped with soybean not only N situation could be improved butalso P situation could be.2In intercropping,the pH of soybean rhizospherewas decreased by increasing the R-Apase activity,which could decelerate thetransforming and fixing P fertilizer.3In both monoculture and intercroppingsystem,the soil pH of rhizosphere was affected by cropping system at two Plevel which only 0.1-4mm distance from the root surface,but the effect of S-Apase activity in the rhizospher soil by cropping system was less than3mm.In effect,the rhizosphere P was really available nutrient,and applyingP to rhizosphere was effective ways to reduce the P nutrient competition.4Inwheat/soybean intercropping,the peak stage of reduction ability of roots wasthe same as that of the root growth,so that the time compensation appearedin intensity of nutrient absorption.

间套作大豆、小麦、玉米根系Apase的差异又反映出大豆利用土壤磷的潜在能力最大，而玉米最小，可见禾谷类的小麦与大豆间套后不但能改善小麦的氮素营养状况还使磷素营养也得以好转。2）间套大豆根际pH值的下降，导致磷肥施入土壤后形成〓-P的比例显著提高，转化成〓-P等难溶性磷减少，说明间套的大豆能减缓肥料磷在土壤中的转化和固定，减少磷素向无效化方向转化。3）复合群体根际土壤pH值的影响一般只发生在0.1-4mm的根际微区，而土壤磷酸酶的影响供磷与否在距根表3mm以外都无多大差异，说明根际磷才是真正有效磷，根际施磷是解决磷素竞争的有效途径。4）。

Economic and reasonable fertilization was better for improving fertilizing profits and reducing environmental press from unreasonable fertilization.

化肥市场供需调控直接关系到农业生产是否有充足的肥料，农户能否在作物生产第一时间用到化肥，因此，区域化肥经济合理施用与市场供需平衡对于保障区域农业化肥稳定供给具有积极意义。

Other horticultural applications for perlite are as a carrier for fertilizer, herbicides and pesticides and for pelletizing seed.

其他园艺应用珍珠岩为载体的肥料，除草剂和杀虫剂和造粒种子。

Rolls Royce had to pull the name of its newest addition to the Silver Cloud line, which they tentatively named the "Silver Mist," since in German,"mist" means manure.

劳斯莱斯的名字已经撤除其最新的银云线他们暂时定名为&银雾&，因为在德国的&雾&意味着肥料。

It was not that the deficiency in fertilizer was responsible for the crop failure.

不是因为肥料不足才造成作物歉收的。

Fertilizers are rated with three numbers N-P-K, you want to get one with very high P value for plumeria.

肥料上有N-P-K植物生长三要素的数字比率，你要为鸡蛋花挑选磷高的那一种。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
