水稻叶的表皮细胞具有“角质—双硅层”,一层是在表皮细胞壁与角质层之间,另一层是在表皮细胞壁内与纤维素相结合,这种“角质—双硅层”可保护植物免受菌丝入侵,并减少叶面水分消耗。过去我们以早稻原丰早试验证明,硅可促进根系生长, Rice leaf epidermal cells have “keratin - double silicon layer,” one is between the epidermal cell wall and the stratum corneum, the other is in the epidermal cell wall with cellulose combined, this “keratin - double silicon layer” Protect plants from mycelial intrusion and reduce leaf water consumption. In the past, we used early morning harvest test of early rice to prove that silicon can promote root growth,
