稻田“半旱式”栽培是在土壤肥力生物热力学理论的基础上发展起来的一种特殊的水稻耕作法。目前,这一新技术已在我国南方一些省份开始推广,获得了显著的效果。为验证这种新方法在我省低产田的适用性和改土增产效果,我们于1984年引进这一新技术,在平坝县高峰区杨家新寨队作了初试,现将主要结果报告如下。 The “semi-arid” cultivation of paddy fields is a special paddy cultivation method developed on the basis of the theory of bio-thermodynamics of soil fertility. At present, this new technology has been promoted in some provinces in southern China and achieved remarkable results. In order to verify the applicability of this new method in low-yielding fields in our province and the effect of soil improvement and yield increase, we introduced this new technology in 1984 and made a preliminary test of the Yangjiaxinzhai team in the peak area of ​​Pingba County. The main results are reported as follows.
