浙江南部山区山高水冷,虽然土壤中含硅量较高,但由于二氧化硅风化缓慢,溶解度较低,无法被水稻吸收,造成土壤中有效硅营养缺乏(二氧化硅
The mountains in southern Zhejiang are highly water-cooled. Although the amount of silicon in the soil is high, silica can not be absorbed by rice due to its slow weathering and low solubility, resulting in a deficiency of available silicon nutrition in the soil (silica
