碳酸氢铵居我国氮肥产量的第二位,占全国氮肥总产量的40％以上,我省年产碳铵15万吨左右,占全省氮肥总量的20％以上。如何经济合理施用碳铵,提高肥效,增加水稻产量是值得重视的问题。1981—1982年我们在平坝县金银公社水塘四队黄泥田上进行了碳铵用量和用法的水稻田间试验。现将试验结果总结如下。
Ammonium bicarbonate ranks second in China’s nitrogenous fertilizer production, accounting for more than 40% of the total nitrogenous fertilizer output in our province, with an annual output of about 150,000 tons of ammonium bicarbonate, accounting for more than 20% of the total nitrogenous fertilizer in the province. How to apply ammonium bicarbonate economically and rationally, increase fertilizer efficiency and increase rice yield is a problem that deserves attention. 1981-1982 We conducted paddy field trials on ammonium bicarbonate consumption and usage on the yellow muddy fields of the four reservoirs of the Bank of Pingba County, Jinyin Commune. The test results are summarized below.
