Studies on the Roots of Rice Plants by Means of Transparent Plastic Pots. : 1. Influences of soil and fertilizers.

[摘要] The transparent plastic pots made of acrylic acid compound were used to determine the influences of soil (degraded paddy soil or normal paddy soil), fertilizer application and method of cultivation (tilling, weeding and ridging) on the root elongation and root system of rice plants and the oxidizing or reducing condition of paddy soil. These newly devised pots were proved to be durable and convenient for observing the relationship between the roots of plants and the paddy soil condition or fertilizer application.
