| 摘 要： | 对甘肃河西绿洲灌区春小麦垄作栽培条件下的适宜种植密度和施肥量进行了研究，结果表明，种植密度和施肥水平对垄作春小麦产量均有重要影响，并且二者之间存在较强的互作效应。高肥条件有利于垄作春小麦穗粒数和产量的增加，并对种植密度有一定的调节和补偿作用；在增施肥料的同时适当密植，有利于提高垄作春小麦产量水平，种植密度过大时，春小麦产量反而降低。在垄作栽培条件下，春小麦的适宜种植密度为675万～750万株／hm^2，适宜施肥量为纯氮180kg／hm^2五氧化二磷144kg／hm^2。

| Abstract: | In irrigated area of Hexi oasis of Gansu,Study the suitable plant density and fertilizer quantity for spring wheat planted by raise-bed methods,the results showed that effects of plant density and fertilizer quantity on yield of raised-bed planting spring wheat are very obvious,and the interaction between plant density and fertilizer is still obvious.The circumstance of high fertilizer quantity is propitious to increase the seeds per spike of raised-bed planting spring wheat,and there are some adjusted and ... |
