摘 要:用生物有机肥对糯玉米进行随机区组试验,研究其对产量、品质及土壤化学性质的影响。结果表明:①生物有机肥(大三元肥及大二元肥)处理的糯玉米生长健壮、光合效率高、优势明显,在拔节期开始发挥肥效,其果穗灌浆速率明显高于其他两个化肥处理。②在增产性上,大三元肥处理的糯玉米(单穗)的产量高达12688.97kg·hm-2,比化肥处理的产量提高了6.0%~6.9%。③在提高品质上,大二元肥处理的糯玉米粗蛋白含量达11%,大三元肥为10.8%,明显高于化肥处理。④生物有机肥有利于改善土壤化学性质,能有效降低土壤硝态氮含量、土壤交换性盐基含量。Biological organic fertilizer in glutinous corn were used as comparativ e tria l of randomized blocks in order to study its effects on the yield and quality of glutinous corn and soil chemical properties.I ts result indicated the followin g fa cts.Firstly,biological organic fertilizer kept glutinous c orn growing we ll and photosynthetic efficiency high.At stem elongation stage,the fertilizer efficiency of biological organic fertilizer caused significant grain filling rat e better than other treatment.Second ly,the yields of glutinous corns receivin g the big tri-element fertilizer were increased by 6.0%~6.9%in contra st with two chemical fertiliz er treatments,is 12688.97Kg ·hm-2 .Thirdly,the biological organic fe rtilizer can effectively improve th e q uality of glutinous corn than the c hemical treatment,crude pertain content of glutinous corn in the big twi-elemen t fertilizer and the big tri-element f ertilizer treatment is 11%,10.8%respectively.Finally,applying the bio logical organic fertil izer to glutinous corn can effectively decrease the nitra te and salt content in soil.
