A Study On Organo-mineral Fertilizers And Their Effects On Crop Growth

The formula and effect of organo-mineral formulated fertilizers produced by LvYuan Biology-Organic Fertilizer Factory in Huai'An on different crops were carried out by pot experiments and field experiments in this study. The main results were as follows:Organo-mineral formulated fertilizers could regulate the proportion of organic and inorganic matters in the fertilizers and increase the input of organic matters and develop the structure and other physical-chemical properties of soils.The formulae of organo-mineral fertilizers for wheat was as follows: organic matter 20%, total content of nutrents 15%, N: P2O5: K2O=8: 3: 4; while it was N: P2O5: K2O=1: 0.5: 1 for rice.The organo-mineral fertilizers could develop the growth of seedling and increase the yield of leaf-vegetable remarkably.The organo-mineral fertilizers could also improve the quality of products, and increase the content Vc and chlorophyll of small cabbage, and reduce the content of nitrate of plant and soil.The organo-mineral fertilizers could increase more production of rape, wheat, rice and other crops than general chemical fertilizers.
