Abstract:

【Objective】This project aims to explore the response of the yield formation pattern of uniform sowing winter wheat to drip irrigation and achieve water-saving and high-yield wheat.【Methods】Using Xindong 22 as the experimental material, field experiments were conducted to study the effects of different drip irrigation volume on plant traits, dry matter accumulation, and yield formation of evenly sown winter wheat, including W1 (1,800 m3/hm2), W2 (2,250 m3/hm2), W3 (2,700 m3/hm2), W4 (3,150m3/hm2), and CK (control, 3,600 m3/hm2).The response of yield formation of uniform sowing winter wheat to different drip irrigation volumes was analyzed.【Results】With the increase of drip irrigation volumes, the SPAD value and dry matter accumulation of each treatment showed a variation pattern of W4>CK>W3>W2>W1; At maturity, compared with CK, W1, W2, and W3 saved water by 50%, 37.5% and 25%, respectively.The dry matter accumulation, dry matter allocation rate, ear length, effective spikelets, ear number, grain number per ear and yield of W1, W2, and W3 were all lower than CK; W4 saved water by 12.5% compared to CK, and its dry matter accumulation, main stem spike length, spike number, spike grain number, and yield were 0.80%, 0.69%, 1.80%, 3.57% and 2.86% higher than those of CK, respectively.The effective spikelets of main stem, tillering spike length, and tillering effective spikelets were 0.71%, 0.52% and 0.00% lower than those of CK, respectively.【Conclusion】Overall, it can be concluded that W4 treatment (3,150 m3/hm2) can meet the water requirements for winter wheat growth and achieve higher yields.

摘要:

【目的】研究不同滴灌量对匀播冬小麦产量形成规律的响应,为小麦节水高产提供依据。【方法】以新冬22号为材料,采用田间试验,设置5种滴灌量处理:W1(1 800 m3/hm2)、W2(2 250 m3/hm2)、W3(2 700 m3/hm2)、W4(3 150 m3/hm2)和CK(对照,3 600 m3/hm2),以上5种处理每次滴灌量均为450 m3/hm2,研究不同滴灌量对匀播冬小麦植株性状、干物质积累的影响,分析不同滴灌量对匀播冬小麦产量形成响应。【结果】随着滴灌量的增加,各处理小麦旗叶SPAD值和干物质积累量均呈W4>CK>W3>W2>W1;在小麦成熟期较CK相比,W1、W2和W3分别节水50%、37.5%和25%,干物质积累量、干物质分配率、穗长、有效小穗、穗数、穗粒数和产量均低于CK;而W4较CK节水12.5%,其干物质积累量、主茎穗长、穗数、穗粒数和产量较CK分别高0.80%、0.69%、1.80%、3.57%和2.86%,主茎有效小穗、分蘖穗长、分蘖有效小穗较CK分别低0.71%、0.52%和0.00%。【结论】W4处理(3 150 m3/hm2)可以满足冬小麦不同生长时期需水量,从而获得较高的产量。
