【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。更多还原

【Abstract】 The concentration and distribution of P in grains and stalks of sorghum, maize and soybean and the harvested P from producing each unit of grains are markedly influenced by soil P condition and crop growing status. A better soil P supply and better crop growth can induce a higher P concentration in grain, larger ratio of grain P/stalk P and more P consumption for producing each unit of grain yields.更多还原
