有机－无机氮不同配比对水稻产量的影响据中农院土肥所张夫道报道：采用１５Ｎ－标记兔粪尿和苕子为有机氮源，以高丰度１５Ｎ－标记硫铵为无机氮源，研究其不同配比对水稻产量的影响。结果表明，无论施有机氮或无机氮均可增加水稻生物量和稻谷产量，而二者的不同配比，其...
Effect of different organic-inorganic nitrogen ratio on rice yield According to the report of Zhang Fudao of soil fertility institute of Zhongnong Academy of Agriculture, the 15N-labeled rabbit excrement and clam were used as organic nitrogen source and high abundance 15N-labeled ammonium sulfate as inorganic nitrogen source. Effect of Different Proportion on Rice Yield. The results showed that no matter organic nitrogen or inorganic nitrogen can increase rice biomass and rice yield, and the two different ratio, its ...
