摘  要:
以百农矮抗58为供试材料,于2009-2010年研究了2种耕作方式(A1:浅耕20cm;A2:深耕30cm)和3种施肥模式(B1:仅施专用复合肥750kg/hm2;B2:施专用复合肥750kg/hm2+鸡粪1 500kg/hm2;B3:施专用复合肥750kg/hm2+饼肥3 000kg/hm2)对豫中地区(漯河)小麦干物质积累和籽粒灌浆的影响。结果表明:与浅耕相比,深耕模式下小麦株高降低,后期植株地上部干物质积累量增加17.5%,籽粒干物质积累量增加5.1%,籽粒灌浆能力增强。B2施肥模式下,穗粒数为36.8粒,比B1模式增加4.9%,千粒重为53.9g,比B3模式高出3.5%,但其成穗数较低,仅为B1模式的94%,因而影响了籽粒产量的提高。A2B2模式下成熟期小麦植株干物质积累量、穗粒数及粒质量均最高,如能进一步提高其成穗数,可以作为该区适宜的耕作施肥模式。

摘  要:
Taking 'Bainong Aikang 58' as experimental material,the effects of 2 tillage methods and 3 fertilization measures on dry matter accumulation and grain filling of winter wheat were studied in Luohe Academy of Agricultural Sciences during 2009-2010.Two tillage methods were tillage depths 20 cm(A1) and 30 cm(A2),while three fertilization treatments included 750 kg/ha compound fertilizer(B1),750 kg/ha compound fertilizer plus 1 500 kg/ha chicken manure(B2),and 750 kg/ha compound fertilizer plus 3 000 kg/ha cake fertilizer(B3).The results showed that,under the deep plowing model,the plant height reduced,the dry matter accumulation of above-ground plant increased by 17.5% during latter growing stage,and the dry matter of grain increased by 5.1%,indicating that the grain filling capacity was improved.Under the B2 model,the grain number was 36.8,4.9% higher than B1 model,and the 1000-grain weight was 53.9 g,3.5% higher than B3 model,but the ear number was about 94% of B1 model,which restrained the grain yield.In the present study,the dry matter accumulation of above-ground plant,grain number per ear and grain weight at mature period were all higher under A2B2 model,which would be the appropriate model if the ear number could be improved.
