不同滴灌量对匀播冬小麦生长发育和产量的影响
Effect of different drip irrigation on the growth,development,and yield of uniform sowing winter wheat
摘要
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 ir-rigation 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.关键词
