据省内17个田间试验点统计,水稻施氯磷铵处理平均亩产488公斤,比尿素磷铵447公斤增产9.2％,比尿素+普钙458.2公斤增产6.5％。在棕壤、草甸土上,氯磷铵对玉米、谷子、棉花和大豆等作物的肥效同尿素磷铵及等养分的单质配合肥大体相等。在中等肥力条件下,氯磷铵对玉米、大豆经济效益最佳施肥量分别为24.7公斤/亩和16.4公斤/亩;对水稻作物在高、中、低三种肥力水平条件下最佳施肥量分别为26.6公斤/亩,45.5公斤/亩和57.8公斤/亩.在粮食作物上,采用氮磷比为 1:1型的复合肥应以50％作基肥.再用50％的单质氮素作追肥经济效益最高。在施用方法上复合肥以作基肥深施和全层施肥效果好,分别比对照增产49.6％和39.1％。
According to statistics of 17 field test points in the province, the average phosphorus yield of rice treated with ammonium chloride was 488 kg, an increase of 9.2% over 447 kg of ammonium phosphate and 6.5% of urea and 458.2 kg of calcium. On brown soil and meadow soil, the effect of ammonium chloride on crops such as corn, millet, cotton and soybean is roughly equal to that of urea ammonium phosphate and other nutrient elements. Under medium fertility conditions, the best economic benefit of ammonium chloride to corn and soybean were 24.7 kg / mu and 16.4 kg / mu, respectively. The optimum fertilization rate of rice crop under high, medium and low fertility levels Respectively, 26.6 kg / acre, 45.5 kg / acre and 57.8 kg / acre. On grain crops, the compound fertilizer with N / P ratio of 1: 1 should be used as basal fertilizer with 50% The top economic efficiency of top dressing. Fertilizer application method for deep basal fertilizer and full-thickness fertilization effect, yield 49.6% and 39.1% respectively over the control.
