不同土壤耕作模式对冬小麦籽粒品质的影响

冬小麦籽粒的品质受土壤环境影响。为了研究不同土壤耕作模式对冬小麦籽粒品质的影响，采用了5种土壤耕作模式(常规耕作秸秆不还田、常规耕作秸秆还田、旋耕秸秆还田、缺口圆盘耙耕秸秆还田、免耕秸秆覆盖)在山东龙口进行了3年田间试验，测定了冬小麦籽粒蛋白质品质、面团流变学特性和淀粉糊化特性。结果表明：少耕模式特别是旋还模式有利于改善籽粒蛋白质质量、改善面粉的加工品质，免覆模式对改变面条蒸煮品质有利。土壤耕作可改变土壤环境，但耕作方式对冬小麦品质的长期影响仍有待于进一步研究。

Effects of different tillage patterns on grain quality of winter wheat

Soil environment influences kernel quality of winter wheat. In order to research the effects of minimum tillage and no-tillage patterns on kernel quality of winter wheat, five tillage patterns were adopted in Longkou city, Shandong Province, for three years. The five tillage patterns were as follows: conventional tillage with no straw turnover(CN), conventional tillage with straw turnover(CS), rotary tillage with straw turnover(RS), serrated disk harrow tillage with straw turnover(HS), no-tillage with straw cover(NC). The kernel protein quality, flour farimograph index, strarch pasting characteristics were investigated. Results show that minimum tillage patterns especially RS could improve kernel protein quality and flour processing quality, NC could improve noodle cooking quality. Soil tillage changes the soil environment. But the effect of long-term soil tillage on kernel quality of winter wheat needs further research.
