Sự thay đổi giữa khô và ngập nước làm tăng tỉ lệ tinh thể và thay đổi tính chất bề mặt của lớp màng sắt trên rễ lúa (Oryza sativa)
Tóm tắt
Lớp màng sắt (IP) rất có giá trị trong quản lý chất dinh dưỡng và khả năng chống chịu ô nhiễm cho cây lúa (Oryza sativa) vì nó có khả năng hấp phụ các chất dinh dưỡng và ion độc hại. Tỉ lệ tinh thể (CR) có thể được định nghĩa là tỉ lệ giữa sắt tinh thể (CI) và tổng số IP để mô tả tính tinh thể của IP. Mặc dù kiến thức về IP đã rất phong phú, thông tin về mối quan hệ giữa điều kiện hình thành, tính chất bề mặt của nó và CR vẫn còn chưa đủ. Trong nghiên cứu này, việc trồng cây lúa trên cát thạch anh và đất được tiến hành để khám phá ảnh hưởng của sự thay đổi giữa khô và ngập nước (DSA) đối với CI, sắt vô định hình (AI), CR, khả năng oxy hóa của rễ (ROC) và tính chất bề mặt của IP trong các thời gian và giai đoạn điều trị khác nhau. Việc điều trị DSA trong 14 ngày đã làm tăng CI lên 2,20 lần so với sau khi ngập nước liên tục (CS) nhưng làm giảm AI xuống còn 72,3% so với sau CS. Tương ứng, CR đã tăng lên 6,89% từ 4,08%. Đặc biệt, CR của IP sau khi DSA kết thúc với tình trạng ngập nước và kết thúc với tình trạng khô lần lượt là 6,89% và 4,23%. Ngoài ra, ROC sau 14 ngày DSA đã tăng lên gấp đôi so với sau CS. Kết quả từ kính hiển vi điện tử quét cho thấy rằng DSA trong 14 ngày đã tạo ra các tấm mỏng hơn với các hạt mịn hơn trong IP so với sau CS. Kết quả từ nhiễu xạ tia X cho thấy rằng IP chứa tỷ lệ cao hơn của goethite, lepidocrocite, magnetite và hematite sau DSA so với sau CS. Tính chất điện tích biến đổi và diện tích bề mặt của IP sau DSA chỉ đạt 26,5% và 32,0% so với sau CS. Nhìn chung, kết quả của chúng tôi chỉ ra rằng sự thay đổi giữa khô và ngập nước ở mức độ thích hợp đã thúc đẩy ROC và sự chuyển đổi từ AI thành CI, và do đó làm tăng CR của IP, đồng thời thay đổi các tính chất bề mặt của nó.
