n-p-fertilizers 解釋
折氮硝酸磷肥
  • n : 1. 【羅馬數字】90〈N＝90000〉。2. 【化學】＝nitrogen. 3. ＝North（ern）。N ＝nuclear 核的：N-waste 核廢料。
  • p :
  1. 67 - 154. 02 % ( no determinate in paddy field on quaternary red clay ), respectively. after organic amendments and fertilizers were added to the metsulfuron - methyl - contaminated soils, microbiai biomass c increased by 0. 23 - 113. 14 % in paddy field on desalting muddy polder, 0. 30 - 46. 48 % in blue clayed paddy, and 1. 82 - 83. 76 % in paddy field on quaternary red clay, respectively, microbiai biomass n in correspoading soils by 4. 27 - 67. 87 %, 5. 43 - 58. 36 % and 5. 05 - 95. 40 %, respectively, and microbiai biomass p by 6. 03 - 139. 59 % 4. 09 - 141. 26 % ( no determinate in paddy field on quaternary red clay ), respectively

    （ 4 ）添加有機、無機物質后，勞去津除草劑污染的三種土壤中微生物生物量碳、氮隨培養時間變化的趨勢基本一致，即0 ~ 7d微生物生物碳、氮降低，但第7d時，添加有機、無機物質的處理中微生物生物量碳、氮均高於僅加養去津的處理和空白對照; 7 ~ 14d微生物生物量碳、氮迅速增加; 14 ~ 42d又下降， 42d后變化較小。
  2. Wheat fertilization mainly in basal, all organic manure, p and k and half of n fertilizers are applied at plowing, the rest n fertilizer dressed in jointing stage along with irrigation

    小麥施肥主要為基肥，全部有機肥、磷、鉀和一半氮肥翻地時施入，其餘氮肥在拔節期隨灌水追施。
  3. We took atrazine and metsulfuron - methyl as examples to evaluate their dynamics of degradation in soils and the responses of microbial biomass after application of organic matters and fertilizers. the objectives are to find out the relationship among of organic matters / fertilizers added, microbial biomass and herbicides degradation, and for remediation of soils contaminated by herbicides. the main results were summarized as follows : effect of organic matters and fertilizers on microbial biomass in soils contaminated by atrazine / metsulfuron - niethyl herbicides ( l ) the contents of soil microbial biomass c, n and p significantly decreased after application of atrazine at the rate of 22

    與空白對照相比，在淡塗泥田中微生物生物量碳、氮、磷分別平均降低了12 . 37 、 11 . 79和11 . 94 ；在青紫泥田中分別平均降低了10 . 70 、 8 . 43和13 . 66 ；在黃筋泥田中分別平均降低了8 . 55 、 11 . 95 （因其酸度較低，微生物生物量磷的測定方法與前兩種土壤的不同，所以未測定其中的微生物生物量磷的含量） 。
