Abstract

Abstract:

The purpose of this study was to explore the irrigation mode of micro-irrigation,water-fertilizer integration technology suitable for the low plain area around Bohai Sea,a two-yield experient was carried out in the same experiment site,in 2014-2015 and 2015-2016 wheat growing seasons to compare the effects of winter wheat research on the spike percentage,spike variation,yield and water consumption of wheat.There were five micro-irrigation treatments;the model of "limited water and stable yield" was set up with two irrigation treatments(T1 and T2 respectively);the "water-saving and high-yield" model was set up with two irrigation treatments(T3 and T4 respectively);T5 treatment was foot water treatment under micro-irrigation mode and 1 flood irrigation control treatment T6.The results showed that:the ratio of 1 spike group and 2 spike group in micro-irrigation was higher than that in traditional border irrigation,the proportion of 3-panicle and 4-panicle was significantly lower than that of traditional border irrigation.The micro-irrigation pattern increased the ability of forming 1 and 2 ears of wheat,the uniformity of single spike weight was significantly higher than that of border irrigation.In 2014-2015,T3 treatment had the highest grain yield,followed by T4 treatment,the yields of the two treatments were slightly higher than those of border irrigation control and T5 treatment,the water use efficiency of T3 treatment was the highest,slightly higher than that of T2 treatment and significantly higher than that of other treatment,it increased by 23.0% compared with border irrigation.In 2015-2016,wheat yield T6>T5>T3>T4>T2>T1,T6 was significantly higher than T1 and T2,and had no significant difference compared with other treatments,the water use efficiency(WUE)of border irrigation was 40.3% higher than that of border irrigation.Comprehensive consideration of cost-saving and efficiency-enhancing,water-saving ecological aspects,under the micro-sprinkler irrigation mode,the best irrigation mode was spring irrigation 2 water(pull-off water,flowering water).
