| 摘 要： | 氮磷化肥配合施用对麦具有交互作用;交互作用大小随氨磷用量及比例而变化;氮磷用量及其比例适宜的组合交互作用值大,增产率最高。试验表明,灌耕灰漠上春麦适宜的氮磷用量及比例,氮(N)每亩10—15kg/亩、磷(P_2O_5)5～7.5kg,以氮(N)磷每亩(P_2O_5)比为1:0.5时经济效益较好。

| Abstract: | Coordination application of N and P chemical fertilizer has an mutual effect on spring wheat. The degree of this effect varies with the application quantity and propertion of N and P. When the application amount and percentage are suitable, not only the value of mutual role become bigger, but also the highest role of increase production appears. The test showed that the application amount of N and P which is fit for spring wheat in irrigation cultivation grey desert soil is 10-15kg per mu for N, 5-7. 5 kgp per mu for P2 O5 as the propertion of N to P2 O5 is 1 to 0. 5 , economic benefit is better. |
