摘要
为实现小麦机械化无垄栽培大面积推广,研究适宜的小麦品种和最优灌溉次数,采用裂区试验选择不同类型的品种、不同的浇水次数,结合产量比较研究不同灌溉条件下的最适宜品种。结果表明,中穗型和大穗型品种产量比较高,相对于多穗型品种更适合无垄栽培;具备灌1~2水条件的地块应选择中、多穗型品种,具备灌2~3水条件的地块应选择中、大穗型品种;灌2水水分利用效率最高。
In order to popularize the mechanized ridge-free cultivation of wheat in large area, the most suitable wheat varieties and the optimal irrigation times were studied. Different types of varieties and different periods of irrigation were selected by split plot experiment to compare the yield and select the suitable varieties under different irrigation conditions. The results showed that the varieties with medium and large spikes had higher yields and were more suitable for ridge-free cultivation than those with multi-spikes;the varieties with medium and multi-spikes should be selected for plots with irrigation conditions of 1 ~2 water, and the varieties with medium and large spikes should be selected for plots with irrigation conditions of 2 ~3 water, and the water use efficiency of irrigation2 water was the highest.
