福建地跨南亚热带和中亚热带两个地带,地形十分复杂,山地丘陵占大部分面积,由于闽中、闽西两大山带大致与海洋平行,斜贯全省,加深东南沿海与西北内陆、沿海平原与河谷盆地之间自然条件的差异.这种区域分异以及耕作管理措施的不同都影响到水稻上的生成和发育.高产水稻土目前主要分布于平原和河谷盆地,尤以平原为多.为了研究高产稳产稻田土壤肥力的基本特性及其地带性、地域性的特征,我们调查访问13个县(市)、22个公社,并采集高产田土样109个,从中选取45个进行化学分析.从高产田土壤环境、剖面性状,理化性质、微形态学特征和管理经验等方面进行研究,现将结果报告如下:
Fujian covers two subtropical and southern subtropical zones, the terrain is very complicated, mountainous hills account for most of the area, as the two major mountain ranges in Fujian and Fujian, roughly parallel with the ocean, obliquely across the province, deepening the southeast coast and northwest inland, The difference of natural conditions between the coastal plains and valley basins affects the formation and development of rice, which is mainly distributed in plain and valley basins, especially in plain In order to study the basic characteristics of the soil fertility and its characteristics of zonality and geography in high and stable yielding paddy fields, we surveyed 13 counties (cities) and 22 communes and collected 109 soil samples from high yield fields, and selected 45 of them for chemical Analysis from high yield field soil environment, profile traits, physical and chemical properties, micro-morphological characteristics and management experience and so on, the results are reported as follows:
