水稻土是人为的水成土。因此这类土壤的发生,起源于人类的意志,但是它的发育则必然服从于自然规律。因为是水成的,所以这个规律变化的内容或范围,将集中于剖面内的水分运动、理、化、生物学性质和作物生长三者的关系和相互间的影响。我们过去的观察和测试结果,固然认为各种客观现象是有联系的,但是所涉及的面并不广。通过仔细和深入地从它们的本质考察研究以后,觉得这些各异的现象,却清楚地反映出它们之间的密切联系而可以构成一个发生学的整体。本文的目的,只是先就宏观范围,初步地探讨这个整体的内容,各组成部分的演变和特征以及论证他们之间的相互关系,为今后的深入研究,铺奠前进的路基。
Paddy soil is man-made soil water. Therefore, the occurrence of such soil originated from the will of mankind, but its development inevitably follows the laws of nature. Because it is hydrated, the content or extent of this regular change will focus on the relationship and interplay between the three components of water movement, physiology, biology, and crop growth in the section. While our past observations and test results, while acknowledging that various objective phenomena are linked, are not extensively covered. After careful and in-depth study of their essence, it is felt that these different phenomena clearly reflect the close relationship between them and constitute an entirety of the genesis. The purpose of this paper is to first discuss the whole content, the evolution and characteristics of each component and the interrelationship among them on a macroscopic scale, and lay a solid foundation for future research.
