目前我省耕地土壤中有80%的面积缺硅或严重缺硅,32.3%的面积有机质含量不足2.0%,这是由于人们长期使用化学肥料或肥料结构不合理,导致耕地土壤酸化板结、肥力下降,以致影响农产品的产量和品质。浙江省农资公司联合省石化厅等有关专家,依据作物需肥规律,土壤供肥特性及肥料性质,将硅素化肥、氮磷钾肥与有机肥进行合理配比,并成功地开发了45%硅素有机肥。该产品具有养分结构合理、肥效持久、壮苗抗病、使用方便、具有改良土壤、提高作物产量
At present, 80% of the arable land in our province is lack of silicon or has a serious shortage of silicon, and 32.3% of organic matter content is less than 2.0%. This is because the long-term use of chemical fertilizers or irrational fertilizer structure leads to soil acidification and soil fertility decline So as to affect the output and quality of agricultural products. According to the law of crop-to-fertilizer, the characteristics of soil-supplying fertilizer and the properties of fertilizers, the relevant experts such as Zhejiang Provincial Agricultural Resources Company and Provincial Department of Petrochemicals rationally matched the ratio of silicon-based fertilizers, NPK fertilizers and organic fertilizers and successfully developed 45% Organic Fertilizer. The product has a reasonable nutrient structure, lasting fertilizer, strong seedling disease resistance, easy to use, with improved soil, increase crop yield
