摘要
为探讨不同土壤条件下追锌肥对小麦产量及品质的影响,在中国农业科学院进行盆栽试验,以津强8号为供试材料进行研究。试验设黑土(A1)、潮土(A2)、红土(A3)3种土壤和不追肥(B1,对照)、拔节期追锌肥(B2)2个处理。结果表明:在3种土壤条件下,子粒产量表现为黑土>潮土>红土,土壤处理间差异显著。追施锌肥比对照显著提高了穗长、穗粒数、千粒重。黑土结合追锌处理,小麦株高、穗长、穗粒数、千粒重均达到最大值,且显著高于其他处理组合。小麦子粒蛋白产量表现为黑土>潮土>红土,土壤处理间差异显著。追施锌肥的小麦子粒蛋白产量显著高于不追施锌肥处理。
In order to investigate the effect of zinc topdressing fertilizer on wheat yield and quality under different soil conditions,a pot experiment was set up using Jinqiang 8 as test material in Chinese Academy of Agricultural Sciences.The experiment had 2 treatments non-topdressing fertilizer(B1),and application of zinc topdressing fertilizer at jointing stage(B2)on 3 types of soil which were black soil(A1),alluvial soil(A2),and red soil(A3).The results showed that under 3 types of soil conditions,the yield of grain was reflected in black soil>alluvial soil>red soil,and there were significant differences between soil treatments.Zinc topdressing fertilizer significantly increased ear length,grains per spike and 1000-grain weight compared with no zinc fertilizer.The wheat plant height,ear length,grains per spike,1000-grain weight of the treatment of black soil combined with zinc topdressing fertilizer all reached the maximum values,and were significantly higher than other treatment.Grain protein yield of wheat showed black soil>alluvial soil>red soil,and the difference was significant.The yield of grain protein in wheat treated with zinc topdressing fertilizer was significantly higher than that without zinc fertilizer treatment.
