摘要: 【目的】探究内蒙古呼伦贝尔市大豆主产区种衣剂和生物菌剂的使用对连作大豆结瘤和生长的影响,为消减大豆连作障碍提供技术支撑。【方法】以蒙科豆8号为试验材料,在内蒙古呼伦贝尔市连作地块上设置多福克种衣剂包衣(DFK)、亮盾种衣剂包衣(LD)、锐胜种衣剂包衣(RS)、生物种衣剂包衣(BIO)、丛枝菌根真菌拌种(AMF)、大豆根瘤菌拌种(SR)和清水拌种(CK)7个处理,分析不同处理对生育期内连作大豆地上部干物质积累量和根瘤干物质积累量的变化规律、生长动态,产量及其构成因素的影响。【结果】生育期内各处理大豆地上部干物质积累量和根瘤干物质积累量均呈先增加后降低的变化趋势,在鼓粒期(R6)达到最大值。与CK相比,R6期各处理地上部干物质积累量增加7.54%~39.40%,增幅次序为LD>SR>AMF>BIO>RS>DFK;根瘤干物质积累量增加8.80%~187.71%,增幅次序为AMF>SR>LD>BIO>RS>DFK。各处理(除LD处理外)地上部干物质快速积累期的起始时间(t1)较CK延迟,各处理根瘤t1较CK提前;DFK、RS处理地上部干物质快速积累期持续时间(Δt)较CK更长,各处理根瘤Δt较CK更长;LD、RS、BIO、AMF、SR处理地上部干物质快速积累期的平均积累速率(Vmean)较CK更快,AMF、SR处理根瘤Vmean较CK更快。种衣剂包衣处理和生物菌剂拌种处理均能增加连作大豆产量,LD、BIO、AMF、SR处理较CK分别显著增产13.55%、12.98%、12.81%、7.80%(P<0.05)。【结论】在内蒙古呼伦贝尔市大豆主产区,使用亮盾种衣剂包衣和丛枝菌根真菌拌种处理下连作大豆地上部干物质积累量、根瘤干物质积累量较高,连作大豆增产效果较好,可以有效消减大豆连作障碍。

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.
