根据不同作物的需肥特点,利用牛粪附加无机养分生产出不同配方的优质有机无机复混肥料,并在玉米、大白菜、芹菜上进行了肥效试验。结果表明,施用玉米专用有机无机复混肥100kg和150kg,玉米产量分别提高13.46%和28.81%;施用蔬菜专用有机无机复混肥200kg和300kg,大白菜产量分别提高24.66%和27.50%,硝酸盐含量分别降低32.70%和42.60%,维生素C含量分别提高32.93%和30.83%;施用蔬菜专用有机无机复混肥300kg和400kg,芹菜产量分别提高15.68%和20.63%,硝酸盐含量分别降低10.67%和12.85%,维生素C含量分别提高8.02%和6.66%。
According to the characteristics of different crops’ fertilization, high-quality organic and inorganic compound fertilizers with different formulas were produced by using cow manure supplemented with inorganic nutrients. Fertilizer experiments were conducted on corn, Chinese cabbage and celery. The results showed that the yield of maize was increased by 13.46% and 28.81% for 100kg and 150kg corn and maize respectively. The application of 200kg and 300kg vegetable organic compound fertilizer increased the yield of Chinese cabbage by 24.66% and 27.50% The content of vitamin C decreased by 32.70% and 42.60%, and the content of vitamin C increased by 32.93% and 30.83% respectively. The yield of celery rose by 15.68% and 20.63% and that of nitrate decreased by 10.67% and 300kg respectively when applying special organic and inorganic compound fertilizer of vegetable, 12.85%, vitamin C content increased by 8.02% and 6.66% respectively.
