Effects of using seed coating agents and biological agents on nodulation and growth of soybean continuous cropping
摘要
Abstract
[Objective]To explore the effects of seed coating agents and biological agents on the nodulation and growth of continuous soybean in the main soybean production area of Hulun Buir,Inner Mongolia,and to provide technical support for breaking soybean continuous cropping obstacle.[Methods]Using Mengkedou No.8 as the experimental material,seven treatments were set up in a continuous cropping field in Hulun Buir,Inner Mongolia,including Duofuke suspension soybean seed coating agent(DFK),Liangdun suspension soybean seed coating agent(LD),Ruisheng suspension soybean seed coating agent(RS),Biological suspension soybean seed coating agent(BIO),arbuscular mycorrhizal fungi seed dressing(AMF),soybean rhizobia seed dressing(SR),and water seed dressing(CK).To analyze the effects of different treatments on the variation,growth dynamics,yield and its constituent factors in above-ground dry matter accumulation and nodule dry matter accumulation of continuous cropping soybean during the growth stage.[Results]The above-ground dry matter accumulation and nodule dry matter accumulation of continuous cropping soybean in each treatment showed a trend of increasing and then decreasing during the growth stage,and reached the maximum value in the drum grain stage(R6).Compared to the CK,the above-ground dry matter accumulation increased by 7.54%to 39.40%in R6,the increase orders were LD>SR>AMF>BIO>RS>DFK.And the nodule dry matter accumulation increased by 8.80%to 187.71%in R6,the increase orders were AMF>SR>LD>BIO>RS>DFK.Compared with CK,the start time of the dry matter rapid accumulation period(t1)of the above-ground was delayed in the all treatments(except LD treatment),and t1 of the nodule was advanced in the all treatments;the duration time of dry matter rapid accumulation period(Δt)of the above-ground was longer in DFK and RS treatments,the Δt of the nodule was longer in the all treatment;the average rate of the dry matter rapid accumulation period(Vmean)of the above-ground was faster in the LD,RS,BIO,AMF,and SR treatments,the Vmean of the nodule was faster in the AMF and SR treatments.Both seed coating agents and biological agents treatment increased the yield of continuous cropping soybean,where LD,BIO,AMF,SR treatments reached significant levels and increased the yield by 13.55%,12.98%,12.81%,7.80%,respectively,compared to the CK(P<0.05).[Conclusion]In the main soybean production area of Hulun Buir,Inner Mongolia,above-ground dry matter accumulation and nodule dry matter accumulation of continuous cropping soybean using the Liangdun suspension soybean seed coating agent and arbuscular mycorrhizal fungi seed dressing are higher,the continuous cropping soybean yield increase effect is better,and it can effectively breaking the continuous cropping obstacle.关键词
