水稻被称为硅酸作物的代表。它是吸收硅酸最多的作物。国外对硅在植物体中的作用已有研究。下面介绍日本在水稻上的研究结果和应用情况。一、硅在植物体中的分布(本刊删去)。二、硅对水稻的作用1.增加磷的利用率:高桥等研究了在不同磷水平条件下,硅的吸收及运转的关系。他把磷的水平分为:无磷(P_2O_5OPPm)、缺磷(P_2O_52PPm)、适量磷(P_2O_510PPm)和过量磷(P_2O_5 50PPm),证明在无磷和缺磷情况下,硅(SiO_2 50PPm)能增加植株伸长、
Rice is known as a representative of silicate crops. It is the most absorbed crop of silicic acid. The role of silicon in plants in foreign countries has been studied. The following describes Japan’s research results and applications on rice. First, the distribution of silicon in the plant (deleted). Second, the role of silicon on rice 1. To increase the utilization of phosphorus: Takahashi et al. Studied the relationship between the absorption and operation of silicon at different phosphorus levels. He classified the levels of phosphorus as P 2 O 5OPPm, P 2 O 52 PPm, P 2 O 5 510 PPm, and P 2 O 5 50 PPm, demonstrating that silicon (SiO 2 50 ppm) increased in the absence of phosphorus and phosphorus Plant elongation,
