| Abstract: | The fertilizer efficiency and residual effect of ammonium sul- fite(ASI),waste fluid of paper making by ammonium sulfite (WPF),anhydrous ammonia(AA) and ammonium sulfite (CK) were studied with planting paddy- rice (O.sativa.L.sub sp.japonica KATO)-whaat (Triticura aestivum L.)-paddy rice in farm-plot and pot culture in Beijing of China from 1984 to 1985 (reap three crops) .Results obtained were summarized as follows: 1.The yield of paddy rice (1st crop) was increased more obviously by ASI, WPF and AA than b... |
