摘要
以花生粤油7号为试验材料开展了田间小区试验,共设置了不施肥(CK)、常规施肥(T1)、有机无机配施-M替代15%氮(T2)、有机无机配施-M替代30%氮(T3)、磷替代-M替代30%磷(T4)、磷替代-M替代60%磷(T5)6个处理,探究有机肥化肥配施对花生产量、品质、土壤肥力及经济效益的影响,筛选出适宜花生生长的有机肥与化肥配施的最佳比例。结果表明,各施肥处理的土壤养分含量、花生产量和品质及经济效益较CK均有所提高;其中T5处理的产量最高,T3处理的O/L值、投入产出比最高,有利于延长花生及其制品的储存时间,提高其经济效益;随着有机肥比例的增加,氮肥、磷肥中的有效成分能被花生更好地吸收利用,提高肥料利用率。
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.
