有机肥和化肥不同比例配施对冬小麦—夏玉米生长、产量和品质的影响
Effects of Different Ratios of Organic Manure and Chemical Fertilizer on Growth, Yield and Quality of Winter Wheat and Summer Maize
摘要
Abstract
A field plot experiment was carried out in typical rural areas in Shandong Province to study the optimum ratio of organic manure and chemical fertilizer and the effects of combined application of organic manure and chemical fertilizer on growth,yield and quality of winter wheat and summer maize.There were 5 treatments,100％ organic manure (M),75％ organic manure and 25％ chemical fertilizer (MNPK1),half organic manure and half chemical fertilizer (MNPK2),25％ organic manure and 75％ chemical fertilizer (MNPK3),and 100％ chemical fertilizer (NPK); no fertilization was set as control (CK).The results showed that annual yield treated with MNPK3 was the highest of 12 565.95 kg/hm2 (winter wheat of 6 188.15 kg/hm2,summer maize of 6 377.79 kg/hm2),1.20 times (winter wheat by 90.5％,summer maize by 1.59 times) than that of CK,while it had no significant different with that of NPK treatment.Grain crude protein contents all increased under different treatments.Taking crude grain protein content at mature stage for example,MNPK1 treatment had significant effect:crude protein content of winter wheat was 1.29 times and 3 ％ higher than that of CK and NPK respectively; and the content of summer maize increased by 53％ and 7％ than that of CK and NPK respectively.The dough forming time,dough stability time and precipitation value of winter wheat all improved significantly under M treatment,and increased by 3.95％,4.32％ and decreased by 2.55％ respectively than that of NPK treatment.Comprehensively considering yield and quality,25％ organic manure and 75％ chemical fertilizer was the ideal ratio,which could obtain higher yield than NPK,improve quality to some extent and reduce environment pollution.关键词
