摘要
以春小麦定丰18号为指示品种,在定西市进行了不同栽培方式对春小麦产量和品质的影响试验。结果表明,2017、2018年,不同栽培方式对小麦产量、单位面积穗数、穗粒数、千粒重的影响由大到小均表现为全膜覆土穴播、传统地膜覆盖穴播、露地穴播。其中全膜覆土穴播较传统地膜覆盖穴播、露地穴播处理的春小麦产量显著增加了29.08%~131.56%;单位面积穗粒数增加了14.4%~27.54%。不同栽培方式的春小麦粗蛋白含量、湿面筋含量、容重、沉降值由大到小均表现为全膜覆土穴播、传统地膜覆盖穴播、露地穴播。与露地穴播处理相比,全膜覆土穴播处理的春小麦粗蛋白含量比2017年显著增加了6.02%;湿面筋含量比2018年显著增加了6.15%;沉降值2017、2018年分别显著增加了26.8%、9.94%。因此,黄土高原半干旱区全膜覆土穴播种植模式能够提高小麦产量和品质,是一种适宜该地区的小麦栽培技术。
With spring wheat Dingfeng 18 as the indicator crop,the effects of different cultivation methods on yield and quality of spring wheat in Dingxi City were studied.In 2017—2018,the effects of different cultivation method on wheat yield,number of spikes,spike grain number and 1000-grain weight varied from large to small,such as the whole field soil-plastic mulching,whole plastic-film mulching and open-ground.Compared with whole plastic-film mulching treatments and open-ground treatments,the whole field soil-plastic mulching treatments significantly increased the yield of wheat and number of spikes,the yield increased by 29.08%~131.56%and number of spikes increased by 14.40%~27.54%.The crude protein content,wet gluten content,bulk density and sedimentation value of spring wheat in different cultivation methods varied from large to small,were shown as follows:the whole field soil-plastic mulching treatments,whole plastic-film mulching treatments,and open-ground treatments.Compared with open-ground treatments,crude protein content of the whole field soil-plastic mulching treatments increased significantly by 6.02%in 2017,the wet gluten content increased significantly by 6.15%in 2018 and the sedimentation value increased significantly by 26.8%and 9.94%respectively in 2017—2018.Therefore,the whole field soil-plastic mulching planting mode can improve yield and quality of wheat in the semi-arid region of the Loess Plateau,which is a suitable wheat cultivation technique in the region.
