为筛选适宜的菌渣肥配方,减轻农业副产物对环境的危害,提高农业生产的可持续性,以不施菌渣肥为对照(CK-JZ0),探讨了菌渣、牛粪不同体积配比的菌渣肥(JZA(纯菌渣)、JZB(菌渣/牛粪=0.5)、JZC(菌渣/牛粪=1)、JZD(菌渣/牛粪=2)在3 000(JZ1)、6 000(JZ2)、9 000(JZ3)kg/hm23个施用量水平上对小麦产量及其构成因素的影响。结果表明,采用菌渣和牛粪配合施用时,在施用量较低(3 000 kg/hm2)或两者配比不适宜(JZD)时对产量有抑制作用,在适宜的施用量(6 000 kg/hm2、9 000 kg/hm2)和适宜的配比(JZA、JZB、JZC)下才表现出较为明显的增产效果。与CK-JZ0相比,当菌渣和牛粪配合施用量为6 000 kg/hm2时,JZB处理对小麦株高、总干物质量、穗粒数以及JZA处理对小麦的穗粒数有连续稳定的促进作用,JZA处理平均较CK-JZ0增产4.7%;当菌渣和牛粪配合施用量为9 000 kg/hm2时,JZA、JZB、JZC处理对株高、穗长、穗粒数以及JZD处理对穗粒数有持续稳定的促进作用,其中JZB、JZC处理表现出稳定的增产效果,平均分别较CKJZ0增产6.7%、15.9%。
In order to screen the suitable bactericide formula, reduce the harm of agricultural by-products to the environment and improve the sustainability of agricultural production, the non-application of residue as CK (CK-JZ0) JZA (bacteria residue / cow dung = 0.5), JZC (bacteria residue / cow dung = 1), JZD (bacteria residue / cow dung = 2) at 3 000 (JZ1 ), 6 000 (JZ2) and 9 000 (JZ3) kg / hm23 on the yield and its components of wheat were studied.The results showed that with the application of bacteria residue and cow manure, (Kg / hm2, 000 kg / hm2), or both of them were not suitable (JZD). Under the suitable application rate of 6 000 kg / hm2 and 9 000 kg / JZC) .Compared with CK-JZ0, when the amount of bacteria residue and cow dung was 6 000 kg / hm2, the plant height, total dry matter, grains per spike, JZA treatment had a continuous and stable promotion effect on the number of spikelets of wheat. JZA treatment increased yield by 4.7% on average compared with CK-JZ0. When the combined application of bacteria residue and cow manure was 9 000 kg / hm2, JZA, JZB and JZC treatment High, spike length, grains per spike and JZ D treatment had a continuous and stable promotion effect on grain number per spike. Among them, JZB and JZC treatments showed stable yield increase, with an average increase of 6.7% and 15.9% respectively compared with CKJZ0.
