最新研究表明，作物除了需要大量施用氮（N）、磷（P）、钾（K）肥以外，还需要较多星的硅（si）肥。因为硅元素对农作物的增产增收有着异常神奇的效果。由于其作用不可替代而不容被忽视，所以硅被称为植物生长所必需的第四大营养元素。大量的科学实验证明：原先不被人们重视的
The latest research shows that crops need more star silicon than just nitrogen (N), phosphorus (P) and potassium (K) fertilizers. Because of the increase of silicon yield on crops has an amazing magic effect. Because of its irreplaceable role can not be ignored, so silicon is called the fourth largest nutrient necessary for plant growth. A large number of scientific experiments show that: originally not be valued
