Effects of Different Fertilization Treatments on Soil Fertilization and Maize Yield

The 6 trial treatments such as 50% straw return to field,100% straw return to field,30 m3/ha manure apply to field,60 m3/ha manure apply to field,50% straw plus 30 m3/ha manure apply to field and check(routine fertilizer) were designed to study the effects of different fertilizer treatments on soil fertilization and maize yield.The results showed that: among all the treatments,the soil fertilization occurred in a marked improvement,application of manure apply to field than straw return to field,semi-effective than the full amount,but the available phosphorus content was 30 m3/ha manure apply to field more than 60 m3/ha manure apply to field.The treatments of manure application has significantly improved maize yield,though straw return to field reduced the yield,the yield of 50% straw plus 30 m3/ha manure apply to field was most.
