摘要:

【目的】研究扩大管行比对滴灌春小麦干物质积累和籽粒产量的影响。【方法】在大田条件下,以新春22号和新春44号为供试材料,设置1管4行(TR4)、1管6行(TR6)和1管8行(TR8),3种不同的管行比滴灌带配置方式,测定不同管行比种植方式下,滴灌春小麦植株及各器官干物质积累量、产量和产量构成因子等指标。【结果】不同处理下2个小麦品种的单株和各器官干物质积累量随带宽增加均呈下降趋势,且均以TR4处理为最大。在TR4处理下,2个小麦品种的总干物质积累量于成熟期达到最大值,且新春44号干物质积累量高于新春22号。新春44号干物质最大积累量、干物质积累速率均高于新春22号。2个品种的籽粒产量均随着带宽的增加呈下降趋势,在TR4处理下,新春22号和新春44号的籽粒产量分别为7 716.45和8 096.48 kg/hm2【结论】在TR6处理下,小麦籽粒产量降幅较小,新春44号产量降幅度小于新春22号,且新春44号籽粒产量高于新春22号。新春44号更适于在大管行比滴灌种植方式下种植。

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.
