贵州是典型的立体农业气候,研究大豆蛋白质含量与气候、土壤肥力的关系,对品质育种和定向区域化栽培具有重要意义。 一、材料和方法 1985年在全省不同纬度和海拔的12个点种植相同的9个大豆品种。各点的玉米和大豆间作为1∶2,随机排列,三次重复。各点分别记载生育期降水量、平均气温、日照时数等。成熟时随机取各品种种子作蛋白质含量分析(凯氏法),以五点取样测定土壤有机质(油洛法)。土壤全氮、碱解氮(凯氏法)、土壤全磷、速效磷(铜篮比色法)、土壤全钾、速效钾(火焰光度计法)。同时取11个点,7个品种进行大豆蛋白质与上述因素的相关分析。
Guizhou is a typical three-dimensional agricultural climate. Studying the relationship between soybean protein content and climate and soil fertility is of great significance for quality breeding and oriented regional cultivation. I. Materials and Methods In 1985, the same 9 soybean varieties were planted at 12 points of different latitudes and elevations in the province. Each point of corn and soybean as a 1: 2, arranged randomly, three times repeated. The points were recorded during the growth period precipitation, the average temperature, sunshine hours and so on. When mature, the seeds of different varieties were randomly selected for protein content analysis (Kjeldahl method), and soil organic matter (oil-lovage method) was determined by five-point sampling. Soil total nitrogen, alkaline hydrolysis nitrogen (Kjeldahl method), soil total phosphorus, available phosphorus (copper basket colorimetric method), soil potassium, available potassium (flame photometry method). At the same time take 11 points, 7 varieties of soybean protein and the above-mentioned factors related analysis.
