- Abstract
【Objective】 To study the effects of expanding pipe-row ratio on dry matter accumulation and grain yield of spring wheat under drip irrigation. 【Methods】 The field experiment consisted of 3 treatments: TR4(one pipe for 4 rows), TR6(one pipe for 6 rows) and TR8(one pipe for 8 rows) for measuring dry matter accumulation, yield and its composition with two wheat varieties(Xinchun 22 and 44). 【Results】 The result showed that the dry matter accumulation of the whole plant and organs of the two wheat varieties displayed a downward trend with the increase of bandwidth under different treatments; the total dry matter accumulation of the two wheat varieties reached the maximum under TR4 treatment, and the dry matter accumulation of Xinchun 44 was higher than that of Xinchun 22; The maximum dry matter accumulation amount and dry matter accumulation rate of Xinchun 44 were higher than those of Xinchun 22. The grain yields of both varieties showed a downward trend with the increase of the bandwidth; the highest yields of Xinchun 22 and Xinchun 44 were 7,716.45 kg/hm2 and 8,096.48 kg/hm2 under TR4 treatment. 【Conclusion】 The wheat grain yield decreases by a small amount under TR6 treatment, the yield decline of Xinchun 44 is smaller than that of Xinchun 22, the grain yield of Xinchun 44 is higher than that of Xinchun 22, and the economic performance of Xinchun 44 is higher. Therefore, Xinchun 44 might be more suitable for planting in the expanding pipe-row ratio drip irrigation mode.
