不同种植模式对小麦/玉米带田水分利用效率的影响研究

在小麦/玉米带田对玉米带采用平作、开沟种植、微垄种植3种种植模式进行了带田水分利用效率的影响研究.结果表明:不同种植模式下带田小麦的产量差异不显著,玉米带开沟种植处理的小麦、玉米合计产量最高,为16 503.8 kg/hm2,平作次之,微垄种植最低;开沟种植模式玉米与小麦间0～100 cm土层土壤的平均含水量的差异最大,微垄种植次之,平作最小;玉米带开沟种植模式带田的玉米单株产量、百粒重、生物产量、双棒数、行数、行粒数、株高、穗周长、穗长均高于其它处理,而穗位高、茎周长、秃顶长最小.

Effect of Different Plant Patterns on Water Use Efficiency in Wheat/maize

The water use efficiency was studied in intercropped wheat and maize which Corn Belt was divided into flatten culture,furrow cropping,ridge cropping three patterens.The results showed that the variance of wheat yield in different patterns has no significant,But the total yield in furrow cropping has highest seed yield(16,505.8 kg/hm~2)of three patterns;The variance of mean soil moisture content in furrow cropping is more higher than ridge cropping and flatten culture between 0~100 cm soil depth of wheat/maize intercropping;The corns yield per plant,100 grain weight,biomass,double ear,row number,seed number of row,plant height,ear perimeter,ear length of furrow cropping are higher than other handling,But the ear diameter,culm perimerter,baldness length are minimalists.
