Effects of Combined Application of Organic Fertilizer and Chemical Fertilizer on Soil Physicochemical Properties,Yield,Quality and Economic Benefits of Peanut
This study adopted a field plot test,used peanut Yueyangou 7 as the test material,and set up a total of six treatments,including no-fertilization treatment(CK),conventional fertilization treatment(T1),organic-inorganic-matching-M replacing 15%nitrogen treatment(T2),organic-inorganic-matching-M replacing 30%nitrogen treatment(T3),phosphorus-replacing-M replacing 30%phosphorus treatment(T4),phosphorus substitution-M substitution 60%phosphorus treatment(T5).The effect of combined application of organic fertilizers and chemical fertilizers on peanut yield,quality,soil fertility and economic benefits was studied.The optimum ratio of organic fertilizer and chemical fertilizer suitable for peanut growth was selected.The results showed that the soil nutrient content,peanut yield and quality,and economic benefits of each fertilization treatment were better than those of the non-fertilization treatment.T5 treatment had the highest yield.T3 treatment had the highest peanut oleic acid/linoleic acid(O/L)ratio,and the highest input-output ratio,which is conducive to the storage of peanuts and their products and improving their economic benefits.With the increase of the proportion of organic fertilizer replacing part of the chemical fertilizer,the active ingredients in nitrogen and phosphorus fertilizers can also be better absorbed and utilized by peanuts,and the utilization rate of fertilizers can be improved.
