我们通过沿江高沙土地区小麦超高产田攻关试验和不同氮肥运筹,磷钾肥不同用量试验,分析植株体内氮、磷、钾吸收、变化动态,以探明高沙土地区小麦亩产500kg以上养分吸收特点和群体质量栽培的营养生理特点,为生产上肥料合理配方,科学运筹提供依据。1小麦超高产养分吸收特点1.1氮、磷、钾养分吸收总量在较高水平上协调一致 测定结果表明,小麦植株养分吸收量与产量呈二次曲线关系(见表1),三要素之间呈显著或极显著正
Through high-yielding fields along the Yangtze River wheat high yield test and nitrogen fertilizer operation, different doses of phosphorus and potassium fertilizer plant analysis of nitrogen, phosphorus and potassium absorption and dynamic changes in the high-sandy soil area of ?? more than 500kg per mu yield of nutrients absorption And nutrition and physiological characteristics of group quality cultivation for the production of fertilizers reasonable formula, provide scientific basis for scientific management. 1 characteristics of super-high-yield wheat nutrient absorption 1.1 total nitrogen, phosphorus and potassium absorption of nutrients at a high level of coordinated measurement results show that wheat plant nutrient uptake and yield showed a quadratic curve (see Table 1), between the three elements Significant or very significant positive
