Effect of acid soil on dry matter accumulation and Al and nutrient contents of barleys differing in acid soil toleranceThe experiment was conducted by using 10 barley genotypes with different acid soil tolerance at seedling stages, each 5 genotypes for acid tolerance and sensitivity, to determine the difference in biomass accumulation, Al and nutrient content in the roots and shoots among genotypes under the condition of acid soil stress.

低pH和两种铝处理下植株各器官ca、Mg含量，茎杆和叶片P、K含量，叶片Fe、MO、Zn含量以及茎杆Zn、B含量和根系及叶片Mn含量均降低，铝福复合处理时降幅更大。100林MAI处理，大麦幼苗整个试验期间根系分泌的苹果酸、柠檬酸和唬拍酸含量与对照相比均增加，且耐铝基因型增幅大于铝敏感基因型，表明铝诱导这些有机酸分泌量增加可能与品种耐铝性有关。

There was an obvious effect of different N, P and K application rates on N, P, K concentration of stem, leaf, rhizome and total ginger plant in each growth period, the uptake and accumulation of nutrient and distribution increased greatly. Ginger in the treatments of moderate fertilizer application rate of N450, P120 and K450 had a higher N, P and K concentration, which resulted in the increase amount of nutrient uptake and accumulation.

This two species of Gloiopeltis could mature and release spores at illuminance 2 500~8 500 lx. For no nutrient addition to the stocking water the two species of Gloiopeltis could mature and release spores, while nutrient addition too high (80 mg·L-1 NaNO3 and 8 mg·L-1 KH2PO4) it was not good for the mature and spores release of this two species alga.

结果表明，在水温10~20℃培养条件下，海萝能成熟放散孢子；在水温12~24℃时，鹿角海萝能成熟放散孢子；在光照2 500~8 500 lx的范围内，2种海萝均能成熟放散孢子；培养海水中不添加营养盐对这2种海萝的成熟没有影响，培养液的浓度高达硝酸钠80 mg·L-1、磷酸二氢钾8 mg·L-1时反而不利于藻体的成熟及孢子放散附着。

Within a short time span of just over 40 years China has developed from an insignificant to the world's largest and still fastest growing producer and user of chemical nitrogen fertilizer. Unfortunately China is now also the country with the most unbalanced nutrient ratio. If continued into the future, the grave nutrient imbalance that prevails at present threatens the fertility of China's soils that has been maintained so well over the centuries, thereby also threatening, sustainable agriculture.

仅40多年时间里中国就从世界上微不足道的氮肥使用国发展成为最大的、而且增长速度最快的氮肥生产和使用国，令人遗憾的是中国是世界氮、磷、钾使用最不平衡的国家，如果任凭这种趋势继续下去，将势必对数千年来我们祖先一直维持良好的地力造成威胁，由此也对农业持续发展带来威胁。
