碳铵粒肥深施碳铵是一种挥发性氮素化肥,为了寻找一种经济有效的施用方法,1977～1978年度,我们在油菜上作了碳铵粉、粒肥的对比试验。供试品种:胜利青梗,前作棉花。于十一月十二日移栽,密度每亩9200株。试验设四个处理:①碳铵粒肥深施,②碳铵粉肥深施,③碳铵粉肥渗水浇施,④对照(不施化肥),小区面积0.115亩,重复一次。油菜腊肥于12月27日施用,每亩30斤。粒肥深施与粉肥深施的均作穴施,粉肥渗水浇施的每斤碳铵渗水120斤。其余的用肥时间、
Ammonium Carbonate Fertilizer Ammonium bicarbonate is a volatile nitrogen fertilizer, in order to find a cost-effective application method, from 1977 to 1978, we made a comparative test of ammonium bicarbonate and granular fertilizer in rapeseed. Test varieties: victory Qing stem, before the cotton. Transplanted on November 12, the density of 9200 plants per acre. The experiment set up four treatments: ① deep application of ammonium carbon fertilizer, ② deep application of ammonium bicarbonate fertilizer, ③ ammonium bicarbonate fertilizer seeping irrigation, ④ control (no fertilizers) and plot area of 0.115 mu, repeated once. Rapeseed manure applied on December 27, 30 pounds per mu. Fertilizer deep application of fertilizer and fertilizer are applied as a point of deep application, fertilizer fertilizer seepage infiltration of ammonium bicarbonate per kilogram of water seepage 120 pounds. The rest of the fertilizer time,
