The utilization of straw and chemical potassium in rice\|wheat rotation system,respectively,was studied by means of a pot experiment.The results showed that the two harvest crops' yield of applied straw potassium was approximately equal to that of applied chemical potassium.Compared with chemical potassium,straw potasium application resulted in lower utilized coefficient.In present harvest and higher in next harvest,however,there wasn't tremarkable difference of two harvest' averge utilized coefficient.On the basis of straw potassium applied,coperated application nitrogen was necessary,especially in wheat.In addition,about 80% potassium absorbed by crops distributed in the straw,only 10% in the grain,and 5% in the root.

采用盆栽试验 ,研究秸秆钾和化肥钾两种不同来源的钾素在作物和土壤中的吸收利用情况。结果表明 :施用秸秆钾与化肥钾 ,稻麦轮作制中两季作物总产量基本相当 ;作物对秸秆钾与化肥钾的两季利用情况有较大差异 ,但两季总吸收量与利用率相差不大 ;作物施用秸秆钾当季应加强氮素的配合施用 ,特别是在小麦上 ;作物所吸收的秸秆钾与化肥钾有约 80 %以上贮存于秸秆中 ,只有约 10 %左右通过籽粒带走 ,另有约 5%存在根茬
