本文综合报道了高产稻区水稻高产稳产低耗高效综合栽培技术研究的主要结果。通过三年的调查和试验研究,弄清了高产稻区水稻生产的现状。水稻高产低耗栽培的群体结构动态和干物质生产的特征、氮肥对群体结构的调控作用、植物生长调节物质对防止早衰的生理效应、以及主要病虫害发生危害规律及其防治。提出了适合于我省高产稻区推广应用的水稻高产低耗栽培各生育时期的形态生理指标及其综合栽培技术模式。研究成果经1990—1991年在醴陵、湘阴两试验基点示范,获得了全年亩增产20kg以上,全年亩增加纯收入20元以上的显著经济效益。
This paper comprehensively reports the main results of high-yielding and low-yielding and high-efficiency integrated cultivation techniques of rice in high yielding rice areas. Through three years of investigation and experimental study, the status quo of rice production in high yielding rice areas has been clarified. The characteristics of population structure dynamics and dry matter production in high-yielding and low-yielding rice cultivation, the regulatory effect of nitrogen fertilizer on population structure, the physiological effects of plant growth regulating substances on preventing premature aging and the pests and diseases of major pests and diseases. The paper put forward the morphological and physiological indexes suitable for the popularization and application of high-yielding rice in our province during the high-yielding and low-yielding cultivation of rice and their comprehensive cultivation techniques. The results of the research in 1990-1991 in Liling, Xiangyin two pilot base model, access to the annual increase in yield more than 20kg mu, the annual increase of more than 20 yuan of pure income of significant economic benefits.
