一、前言稻作的营养问题在我国南方稻区已有较多研究。由于辽宁气候、土壤、品种和栽培方式都和南方稻作有一定差别,植物营养也必然有其特点。近几年大面积推广水稻杂交种,对其营养特性还缺少研究。为此,我们在开展稻作营养研究的同时,主要偏重于微量元素对水稻杂交种生长效应的研究,并结合沈阳郊区草甸水稻土的化学性质与元素含量,阐明其对提高产量的可能性。二、材料与方法试验包括盆栽与土壤分析。盆钵试验在取土田间近旁的试验场内进行,采用当地灌溉水。供试水稻杂交种为“黎明 A×C57—167”、保持系“黎明”、及恢复系“C57—167”。盆钵
I. INTRODUCTION The nutritional problems of rice have been studied more in rice growing areas in southern China. As Liaoning climate, soil, variety and cultivation methods are different from the South rice, plant nutrition must have its own characteristics. In recent years, large-scale promotion of rice hybrids, the nutritional characteristics of the lack of research. Therefore, while carrying out the research of rice nutrition, we mainly focus on the effect of trace elements on the growth effects of rice hybrids. Combining the chemical properties and elemental contents of the meadow paddy soil in suburbs of Shenyang, we clarify its potential for increasing yield . Second, materials and methods Tests include potting and soil analysis. The pot test was carried out in the test field near the borrowed soil field using local irrigation water. The tested hybrid rice varieties were “Dawn A × C57-167”, maintaining “Dawn” and restorer “C57-167”. Pot bowl
