摘要: 土壤P供应状况及作物生长好坏可明显影响高粱、玉米、大豆籽实及秸秆中的P浓度、P在籽实及秸秆中的分配比和形成单位籽实产量的P收获量。P供应充分,作物生长良好(产量高),籽实中的P浓度高,籽实P/秸秆P的分配比大,每形成单位籽实消费的P量高。

关键词: P循环, 作物体内P分配

Abstract: The concentration and distribution of Pin grains and stalks of sorghum, maize and soybean and the harvested Pfrom producing each unit of grains are markedly influenced by soil Pcondition and crop growing status. Abetter soil Psupply and better crop growth can induce a higher Pconcentration in grain, larger ratio of grain P/stalk Pand more Pconsumption for producing each unit of grain yields.

Key words: Phosphorus cycling, Distribution of phosphorus in crops
