鉀指數
英文
potassium index-
Based on the experimental results, several measures including the selection of high - yielding, high nutrient - efficiency variety, correct crop management practices to increase harvest index and returning rice straw to soil were suggested to keep nutrient ( particularly k ) balance in soil - crop system with high - yielding rice production
根據試驗結果推薦了幾項高產措施，包括選用高產、高養分利用率品種、改進作物管理措施以提高收獲指數和稻草還田，在水稻高產生產土壤作物系統中保持養分（尤其是鉀）平衡。The result of experimentation on coupling effect of water and fertilizers on spring corn in the three gorges reservoir area indicate that water stresslead the effect low of highness and lai, and the most effect is made in shooting stage ; it has a significant positive correlation between the yield of corn and biomass, and hasn ' t none significant positive correlation between the yield of corn and the weight of roots ; the coupling effect of water and n is significant, but the coupling effect of water and k is not significant, the maximum yield of corn condition fitting - water and medium n, corn absorbs n has a threshold value during the growth, and using superfluous n is able to prick up soil drought and crop drought ; water is the leading factor which effects the yield of corn, next is n and k
摘要三峽庫區春玉米盆栽水肥耦合試驗研究結果表明，水分脅迫導致玉米株高和葉面積指數降低，以拔節期受到影響最大；玉米產量與生物量呈顯著正相關關系，產量與根重無顯著正相關關系；水氮耦合效應顯著，適宜水分和中氮處理下玉米的產量最高，玉米生長發育對氮肥的吸收存在一定的閾值，過多施用氮肥會加劇土壤乾旱和作物乾旱，水和鉀耦合效應對玉米產量影響不顯著；水分是影響玉米產量的主導因素，其次是氮效應和鉀效應。The result indicated that, the output value per labour force, the output value of unit field area, the output value per person are the major indexes of the first principal components, the balance index of n, the output value per labour force and the pesticide quantity per unit field area are the major quotas of the second principal components, the balance index of p, the balance index of k and the output value per person are the major indexes of the third principal components
結果表明：勞均產值、單位耕地產值、人均產值是決定第一主成分的主要指標；氮平衡指數、勞均產值、單位耕地施用農藥量是決定第二主成分的主要指標；磷平衡指數、鉀平衡指數、人均產值是決定第三主成分的主要指標。The main factors influencing the accuracy of the determination of permanganate index, include acidity of sample, water distilled water quality, potassium permanganate concentration, water bath temperature and titration time
摘要影響高錳酸鹽指數測定準確性的主要因素有樣品酸度、蒸餾水水質、高錳酸鉀溶液濃度、水浴加熱溫度和滴定時間。Under the direction of chinese soil taxonomy, part purple soils developed on the purplish standstones of j2 # j3 in sichuan basin were systematically studiedaccording to natural landscape, profile modality and quick - test, applying to methods statistic analysis and system integration, main affecting factors, indexs of soil series taxonomy and retrieval orders were systematically discussed. the results showed : 1 ) organic substance, total nityogen, total phosphate, total potassium and particle size composition were distinctly related with many soil characters. organic substance, calcium carbonate, available phosphate # size composition were much different in all swatches. besides, soil structure and the depth had profound affection to it. 2 ) affecting factors : soil structure, texture style and organic substance phosphorous
本文以土壤系統分類理論為指導，以四川盆地侏羅系蓬萊鎮組、沙溪廟組和遂寧組紫色巖上發育形成的部分紫色土為研究對象，利用spss統計軟體相關功能，結合供試土壤的自然景觀、剖面形態和室內測定的理化性質，對土系分化的影響因子、土系劃分指標和檢索順序進行了系統的探討，結論如下： （ 1 ） 、供試紫色土中有機質、全氮、全磷、全鉀和顆粒組成與多個土壤性質均呈顯著或極顯著相關；有機質、碳酸鈣、有效磷、顆粒組成等性質在供試土壤方差分析中變異系數均較大；土體構型及土體的深度對土壤性質也有深刻影響。( 3 ) the amounts of total k, slowly available k, rapidly available k, and dissolved k lost in the runoff increase obviously with the increase of slope gradient. the relationships between slope gradient and amount of total k, slowly available k, rapidly available k, and dissolved k loss can be expressed by exponential functions
（ 3 ）全鉀、緩效鉀、速效鉀和溶解態鉀流失量隨坡度增大而增加的規律十分明顯，且全鉀、緩效鉀、速效鉀和溶解態鉀的流失量與坡度呈顯著的指數函數關系。分享友人
