Abstract:
【Objective】 To study the effects of integrated and uniform cultivation techniques on the growth, development and yield of winter wheat in southern Xinjiang.【Method】A field experiment was conducted by setting two different sowing methods: integrated sowing and conventional strip sowing, and the variation of chlorophyll content (SPAD value), leaf area index (LAI), dry matter accumulation, yield and yield components of winter wheat leaves were observed under different sowing methods.【Result】The results showed that compared with strip sowing, uniform sowing treatment was beneficial to the increase of chlorophyll content (SPAD value) and leaf area index (LAI), to promotion of dry matter accumulation, and thus grain yield was effectively increased. Besides, compared with the conventional strip sowing, the costs of the uniform seeding, soil preparation, fertilization and sowing included, were saved by a total of 1,320 yuan/hm
2 and the input of fertilizer was saved by 421.5 yuan/hm
2. What was more, the two years’ output benefits were increased by 5.93% in 2017 and 22.75% in 2018, respectively.【Conclusion】The results of comprehensive comparison and economic benefits obtained were: the integrated uniform sowing of winter wheat had the advantages of high yield, cost saving and efficiency, and high fertilizer utilization rate, which might be recommended as a reference for local production.
