黑龙港流域不同浇水次数对小麦的影响

Effects of Different Watering Times on Wheat in Heilonggang Basin

为探讨适合黑龙港流域种植的小麦品种以及配套的节水稳产技术,研究了不同浇水次数对小麦产量的影响。结果表明:为节约水资源,宜优选春季灌水1次,在拔节期浇水,结合浇水追施尿素225 kg·hm^(-2);在同等土壤肥力和栽培条件下,为提高产量,宜优选烟农172、尧麦16、邯115276、洛麦7号和济麦23;3种浇水处理条件下,株高均直接或间接地对产量产生显著影响,一定程度下株高越高产量相应越高。

In order to explore wheat varieties suitable for planting in Heilonggang basin and the corresponding water conservation and stable production techniques,we studied the effects of different watering times on wheat yield.The results showed that we optimize 1 water for water conservation,namely irrigated once in spring.We watered at jointing stage,combined with applying urea 225 kg ·hm ^-2 .Under the same soil fertility and cultivation conditions,we preferred to choose Yannong 172,Yaomai 16,Han 115276,Luomai 7 and Jimai 23 to increase wheat yield.Under three watering treatments,plant height directly or indirectly had a significant effect on wheat yield.To a certain extent,the higher the plant height,the higher the yield.
