本项研究,以宝山区夹砂泥土壤为代表,在土壤养分含量较低的土壤上,就小麦的养分吸收,营养物质积累和分配与施肥关系,研究小麦高产施肥技术。1高产小麦的养分吸收量 小麦养分吸收量,受植株养分含有率和生物产量两因素影响。高产小麦不仅生物产量较高,且植株养分含有率也有别于一般产量小麦,表现为磷、钾含量高,特别是秸秆的含钾量,几乎是成倍增加。据 In this study, Baoshan sand soil as a representative, in the soil nutrient content of the lower soil, on the nutrient absorption of wheat, nutrient accumulation and distribution and fertilization, wheat high yield fertilization techniques. Nutrient uptake of high-yielding wheat Nutrient uptake by wheat, the plant nutrient content and biological yield of two factors. High-yielding wheat is not only high in biological yield, but also different from the general yield of wheat in nutrient content, showing high phosphorus and potassium content, especially the potassium content of straw, almost doubled. according to
