提高矿质肥料效力的方法之一,是将它与有机肥料混合施用。我们以少量的厩肥,在播种前不久与适量的矿质肥料一起施用,获得了良好的效果。在有机质贫乏的土壤上,这种肥料的优良作用,表现得很明显。全苏棉作科学研究所的试验确定,在栽培棉花的灰钙土上,施用与有机质混合的磷肥,能提高植物吸收磷素的能力。大田实验结果,每公顷能增加籽棉2—6公担。有机矿质混合肥料的这种作用,是由于防止土壤在化学上固定磷素的生物学上的吸
One of the ways to improve the effectiveness of mineral fertilizers is to mix it with organic fertilizers. We use a small amount of manure, shortly before sowing with the appropriate amount of mineral fertilizer applied together, and achieved good results. The excellent effect of this fertilizer is evident in soils poor in organic matter. All Soviet cotton for the Institute of Science to determine the experiment, in the cultivation of cotton on the calcareous soil, the application of organic matter mixed with phosphate, can improve the plant’s ability to absorb phosphorus. Field test results, hectare can increase seed cotton 2-6 km. This effect of the organic mineral compost is due to the biological absorption of the soil to prevent chemical immobilization of phosphorus
