不同作物吸收氮及灰分元素特点的研究,对不同作物进行合理施肥具有重要意义,对于育种亦有很大参考价值。不同作物氮及灰分元素的特点因不同生态条件及不同作物类型而有很大变化。甚至同一作物不同品种其氮及灰分元素的特点也有所不同。所以,为了合理施肥,应该具体地研究 The research on the characteristics of nitrogen and ash absorbed by different crops is of great significance to the rational fertilization of different crops and also has great reference value for breeding. The characteristics of nitrogen and ash in different crops vary greatly depending on different ecological conditions and different crop types. Even the different varieties of the same crop have different nitrogen and ash features. Therefore, in order to rational fertilization, should be specifically studied
