本试验在美国得克萨斯州立农试站进行,选择盐、碱和正常的轻粘壤土三种土壤的0—10厘米的表层土壤,进行水稻盆栽试验,以研究不同温度和灌溉方法对水稻生长的影响。水稻直播于栽培罐内,在人工气候室内,将夜间(10小时)和白天(14小时)温度分别控制为4和16、10和21、16和27、21和33℃,出苗后12天(早)或24天(晚)进行灌溉,灌溉深度为6—12厘米。出苗后53天割下植株地上部,分析其干物质产量和磷、钾、镁、钠、铁、锰和锌等矿 This experiment was carried out at the Texas State Farm Experiment Station in the United States to select 0-10 cm topsoil of salt, alkali and normal lightly loamy soils to study the effects of different temperature and irrigation methods on rice growth . Rice was planted live in a cultivation tank and the temperature was controlled at 4 and 16, 10 and 21, 16 and 27, 21 and 33 ° C at night (10 hours) and daytime (14 hours) in the artificial climate chamber, respectively, at 12 days after emergence Early) or 24 days (late) irrigation, the irrigation depth of 6-12 cm. The shoots were excised 53 days after emergence and their dry matter production and phosphorus, potassium, magnesium, sodium, iron, manganese and zinc were analyzed
