５年不同肥料培肥定位试验表明：稻草和猪粪及化肥合理配施，对水稻具有一定增产作用，比稻草配合施化肥增产４．７４％；比单施化肥增产１０．１５％；比不施肥增产５６．７５％；其差异显著性达到极显著水平。同时，有利于土壤有机质、全氮、全磷、缓效钾含量均有一定提高，且降低土壤容重，改善土壤环境，提高土壤肥力，利于作物生长，增产效益为佳
Five years of different fertilizers fertilization positioning experiments showed that: straw and pig manure and chemical fertilizers rational allocation of rice has a yield-increasing effect than rice straw combined with chemical fertilizers increased 4.74%; 10.15% than single chemical fertilizer yield; not Fertilization yield 56.75%; the difference was significant to achieve a significant level. At the same time, the content of soil organic matter, total nitrogen, total phosphorus and slow-acting potassium are all increased to a certain extent, and the soil bulk density is reduced, the soil environment is improved, the soil fertility is increased, the growth of crops is benefited, and the yield increase benefit is better
