改良盐碱地有新招美国－土壤专家摸索出一套用纸屑改善盐碱性土质结构的科学方法。具体方法：将纸屑、鸡粪、原质土按４：１：５的比例，混合均匀平铺在贫瘠的土层上。届时掺入纸屑中的纤维素在鸡粪基肥内多种细菌作用下迅速“分化瓦解”，生成胶状白色粘附物，这样，土壤... Improved saline-alkali new tactics United States - soil experts to explore a set of scientific methods of using paper dust to improve saline-alkaline soil structure. Specific methods: confetti, chicken manure, the original soil at a ratio of 4: 1: 5, mixed evenly in the barren soil. The cellulose, which is then incorporated into the paper scraps, quickly “disintegrates” under the action of a variety of bacteria in the chicken manure-based fertilizer and produces a colloidal white adherend, so that the soil ...
