土壤水分状况的改变对作物吸收磷的影响是多方面的,它既影响原有土壤中磷的转化,又影响施入磷的转化及其对作物的效用、吸收和利用等.土壤水分也影响作物根或茎的生长和型式,因而影响对需磷的极限.许多研究者曾报道,小麦对磷肥的吸收与土壤水分状况呈 The change of soil water status has many impacts on the phosphorus uptake of crops, which affects not only the conversion of phosphorus in the original soil, but also the conversion, application, absorption and utilization of phosphorus, etc. The soil moisture also affects Crop root or stem growth and type, thus affecting the limit of phosphorus demand.Many researchers have reported that the absorption of phosphorus on wheat and soil moisture status was
