为了探索汕优二号作麦茬稻栽培的高产规律及其机理,近几年来,我们在重庆市巴县长生乡基点进行了氮肥施用技术、种植密度、水浆管理试验,并辅之以磷钾肥施用技术的试验,采用田间小区试验,盆栽辅助试验及高产栽培示范三结合的研究方法,从植物营养,光合生理,水稻生态等方面进行研究,对试验结果进行了生物统计分析,以高产、稳产、低成本的目标和高光效群体的基本要求,筛选出汕优二号作麦茬稻栽培亩产1,100—1,200斤相应的光合性能、形态、产量等各项指标及调控的技术措施,并在
In order to explore the high-yielding law and mechanism of Shanyou 2 for wheat stubble cultivation, in recent years, we conducted nitrogen fertilizer application techniques, planting density and water slurry management experiment in Changsheng Township, Ba County, Chongqing City, supplemented by phosphorus and potassium fertilizer The experiment of applying technology was carried out. The field experiment, pot auxiliary experiment and high-yielding cultivation demonstration were combined to study the plant nutrition, photosynthetic physiology and rice ecology. The biochemical statistics of the test results were carried out. , Low-cost target and high light efficiency group, the paper selected the corresponding measures of photosynthesis, morphology and yield of Shanyou No.2 for stubble rice cultivation of 1,100-1,200 kg per mu,
