本文研究了水稻作物中 N、P、K、Ca、Mg、Fe、Si 和 Cu 的含量动态。确定以计算100公斤水稻籽粒中无机营养元素的消耗作为全部土壤类型上所有研究品种和施肥量的常数指标。根据元素消耗的多少排列顺序为 Si>K>N>P>Mg>Ca>Fe>Cu。作物中无机物质的含量主要由它们的生物学特性、作物生长及生长的土壤气候条件和无机营养水平决定,其中作物的生长是决定因素。众所周知,水稻生育初期,无机营养元素的含量最高,随着作物生长而减少,
In this paper, the dynamic changes of N, P, K, Ca, Mg, Fe, Si and Cu in rice crop were studied. It is determined that the consumption of inorganic nutrients in 100 kg of rice grain is calculated as a constant index of all the cultivars and the amount of fertilizer applied to all the soil types. According to the amount of elements consumed in the order of Si> K> N> P> Mg> Ca> Fe> Cu. The content of inorganic substances in crops is mainly determined by their biological characteristics, soil and climatic conditions of crop growth and growth and inorganic nutrient levels, of which crop growth is the determining factor. As we all know, the early rice growth stage, the highest content of inorganic nutrients, with the crop growth and decrease,
