Effects of Marsh Fertilizer on Wheat Yield Scab and Soil Nutrients
The comparison test base of new wheat varieties in Tanghe County,Nanyang City,Henan Prov-ince,was divided into 4 standard plots,which were treated as blank control CK group(no fertilization),T1 group(marsh fertilizer 1 200 kg/hm2),T2 group(marsh fertilizer 1 500 kg/hm2)and T3 group(marsh fer-tilizer 1 800 kg/hm2),respectively.The effects of different dosage of marsh fertilizer on wheat growth,dis-ease resistance and soil nutrients in sample plots were studied.Results:(1)Growth process:the whole growth cycle of T2 wheat was shorter than that of T1,T3 and CK(P<0.05),T1 and T3<CK(P<0.05);(2)Yield and economic traits:spike length,effective spike number of 100m2,grain number per spike,1000～grain weight and total yield of 100m2 of T2 wheat were higher than those of T1,T3 and CK(P<0.05),and there was no difference between T1,T3 and CK(P>0.05).The plant height of T2 was lower than T1,T3 and CK(P<0.05).(3)Incidence of SCab:The incidence of T3 SCab was lower than T2<T1<CK,and there was a difference between groups(P<0.05);(4)Soil physical and chemical properties:T3 soil organic matter content>T2>T1>CK(P<0.05);T3 soil pH value<T2<T1<CK(P<0.05);Soil alkali-hydrolyzed ni-trogen,available phosphorus and available potassium showed T3>T2>T1>CK(P<0.05).Application of bog fertilizer is beneficial to shorten wheat growth process,increase wheat yield,prevent disease and improve soil physicochemical properties.The best application rate of bog fertilizer is 1 500 kg/hm2.
