稻田半旱栽培是农艺师莫先武同志在生产实践中,深入钻研农业系统工程学理论和土壤肥力生物——热力学原理,于1978年探索设计出来的一种新耕作技术。1980年以来,以这种新技术为基础模式,选择了冬水田面积大、水热资源丰富、土壤类型齐全的川南长宁县相岭区建立农业综合研究基点,继续深入研究,把种植业和养植业、大、小春作物紧密结合起来,以免耕浸润为核心,逐步成为一种具有强大生命力和发展前途的新耕作制。半旱栽培的特点是人为的改变了稻田微地形,变传统的稻田平栽为垄埂种植,垄埂上植稻,沟内关水养萍养鱼,按水稻不同生育阶段进行水浆管理,实行浸润灌溉(图
Semi-arid rice cultivation is an agronomist Comrade Mo Xianwu in production practice, in-depth study of the theory of agricultural systems engineering and soil fertility bio-thermodynamics principle, in 1978 to explore the design of a new farming techniques. Since 1980, taking this new technology as the basic model, we have chosen to establish a comprehensive agricultural research base in Xiangling District, Changning County, Sichuan Province, which has a large area of winter paddy fields, abundant water and heat resources and a complete soil type. We will continue our in-depth study of planting and raising Planting industry, large and small spring crops closely together, so as to avoid tillage infiltration as the core, and gradually become a new tillage system with strong vitality and development prospects. Semi-arid cultivation is characterized by artificially changing the micro-topography of paddy fields, changing the traditional planted rice paddies for ridge planting, ridge planting on rice, furrow irrigation water Pingping fish, according to different stages of rice water slurry management, Implementation of infiltration irrigation (Figure
