首发时间:2020-05-28
摘要:本试验于2018﹣2019年分别在河北农业大学清苑试验站和辛集马庄试验站进行。采用4个小麦品种,8个玉米品种为试验材料,比较分析了春玉米一熟制(T1)、青贮-粒用玉米一年两熟(T2)、双季甜玉米(T3)和传统冬小麦-夏玉米一年两熟(CK)4种种植模式的周年产量、资源利用率、田间耗水量、经济效益。结果表明:4种种植模式中以CK的生物产量和光能利用率最高,分别比T1-T3模式高出49.6%、23.1%、38.3%和0.53%、0.25%、0.43%;T1的温度生产效率低于CK 21.4%,T2高于CK 1.3%;T1,T3的水分生产效率分别低于CK 7.6%、9.0%,T2高于CK 7.0%;3种试验模式的田间耗水量分别低于传统模式45.4%、28.5%、32.1%;4种种植模式中以T3收益最高,分别高于其他模式45.3%、30.4%、8.7%。本试验筛选出了适宜冀中平原当前水资源状况的节水高效种植模式,可为该区农业高产高效可持续发展提供理论和实践依据。

Studies on the optimization of wheat and maize cropping system in the central Hebei Plain
Abstract:This experiment was carried out in 2 Experimental Stations of HAU of Qingyuan,Baoding and Mazhuang, Xinji during 2018 - 2019. 4 wheat varieties and 8 maize varieties were used as experimental materials to compare and analyze the annual yield, resource utilization rate, field water consumption and economic benefits of the 3 planting modes of spring maize single cropping(T1), silage-grain maize mode(T2) and double seasons sweet maize mode(T3) with the traditional winter wheat-summer maize planting mode(CK). The results showed that the biological yield and light energy utilization rate of CK among the 4 planting patterns, which were higher than the T1-T3 patterns of 49.6%, 23.1%, 38.3% and 0.53%, 0.25%, 0.43%,respectively. The temperature production efficiency of T1 was lower than that of CK 21.4%, T2 was higher than CK of 1.3%. The water production efficiency of T1 and T3 was lower than that of CK 7.6% and 9.0% respectively, T2 was higher than CK of 7.0%. The field water consumption of the 3 experimental models was lower than that of the traditional model 45.4% , 28.5% , 32.1%, respectively. Among the 4 planting modes. T3 had the highest income, which is higher than other planting modes 45.3% , 30.4% , 8.7%, respectively. The water-saving and high-efficiency planting mode suitable for the water resources situation of this region was screened out through this experiment, and it is also providing theoretical and practical basis for high-efficiency sustainable agricultural production.
