It is conducive to uptake soil nitrogen for flue-tobacco on dryland soil with maize-tobacco rotation before topping (60 days after transplanting) and uptake soil nitrogen for flue-tobacco on paddy soil with rice-tobacco rotation after topping.2 The nitrogen utilization efficiency of rapeseed cake, rice straw and rape straw were 19.5%, 15.5%, 8.1% respectively, and the inorganic fertilizer nitrogen utilization efficiency were 41.1%, 42.7% and 35.7% under the combined application of organic additives and inorganic nitrogen fertilizer. The contribution rate of rapeseed cake, rice straw, rape straw to accumulated nitrogen of flue-cured tobacco were 1.0%, 2.4%, 2.7% respectively by the combined application of organic additives and nitrogen fertilizer. Flue-cured tobacco for organic nitrogen absorption meet with the nitrogen needs laws of high-quality tobacco, indicating that the combined application organic additives and inorganic nitrogen fertilizer reduces the nicotine content of tobacco, an increase of sugar/nicotine ratio and improved the quality of tobacco. In which the role of rice and rape straw is greater than the rapeseed cake can be used as measures to lower nicotine.3 Nitrogen accumulation in flue-cured tobacco with the total nitrogen input was a significant positive correlation during the growth stage of flue-cured tobacco.

On the bases of absorption spectra measurements, it is shown that stabilizer is beneficial to the stability of J-aggregate of sensitizing dye Results of reflection spectra and spectral-exposure experiments demonstrate that spectra absorbance are greatly affected by the adding order of stabilizer and sensitizing dye and only stabilizer added after dye can advantage for J-aggregate of sensitizing dye neatly forming on the surface of silver chloride grain and its absorbance be available ESR experiments show that the addition of stabilizers can decrease the number of dye positive hole and accelerate the decay of it Then desensitization aroused by the recombination of dye positive hole with photoelectron and/or latent image center, was reduced at the presence of the stabilizers

通过溶液光谱实验说明稳定剂有利于染料J聚集体的稳定性；反射光谱实验和光谱曝光实验证明稳定剂与染料的添加次序对乳剂的光吸收有很大的影响，只有稳定剂在染料之后加才有利于染料在AgCl颗粒上排列整齐形成J聚集态及其光吸收；ESR实验结果说明稳定剂的加入可以降低染料正空穴的浓度及其衰减速率，使乳剂中染料正空穴减少，从而抑制了染料正空穴引起的减感作用。因此可以认为稳定剂的超增感作用：一是有利于染料形成J聚集态及乳剂的光吸收；二是降低染料正空穴的浓度，从而抑制染料的减感。同时还提出了染料与稳定剂的增感吸附模型。
