间作箭筈豌豆翻压还田减施氮肥对马铃薯生长及产量的影响
Effects of common vetch intercropping and its turning and returning to the field with reduced nitrogen fertilizer on potato growth and yield
摘要
Abstract
[Objective]To investigate the effects of intercropping with common vetch and turning and returning to the field with reduced nitrogen fertilizer on potato growth and yield in the northern foot of the Yinshan Mountains in Inner Mongolia.[Methods]Four treatments were established:potato monocropping with conventional fertilization(CK),potato and common vetch intercropping with conventional fertilization(T1),potato monocropping with 20%reduced nitrogen fertilizer(T2),and potato and common vetch intercropping with 20%reduced nitrogen fertilizer(T3).The effects of different treatments on potato plant height,stem diameter,photosynthetic performance,dry matter accumulation,yield and yield components at different growth stages were compared and analyzed.[Results]Under intercropping conditions,potato plant height,stem diameter,SPAD value,net photosynthetic rate,transpiration rate,intercellular CO2 concentration,stomatal conductance,dry matter accumulation,and yield were all higher than those under monocropping.Compared with CK,at the starch accumulation stage,the plant height and stem diameter of potato in T3 treatment increased significantly by 7.35%and 6.34%(P<0.05),respectively;at the tuber formation stage,the SPAD value,net photosynthetic rate,intercellular CO2 concentration,and stomatal conductance of potato in T3 treatment increased significantly by 10.07%,17.89%,7.57%,and 23.67%(P<0.05),respectively;at the tuber bulking stage and starch accumulation stage,the transpiration rate of potato in T3 treatment increased significantly by 7.58%and 2.40%(P<0.05),respectively;at the mature stage,the dry matter accumulation of potato in T3 treatment increased significantly by 25.14%(P<0.05).T3 treatment achieved the highest yield(37 228.57 kg/hm2),which was 11.70%higher than that of CK;the marketable tuber yield in T3 treatment was significantly 21.63%higher than that of CK(P<0.05).[Conclusion]The treatment of potato and common vetch intercropping with 20%reduced nitrogen fertilizer can significantly enhance potato photosynthetic performance,increase dry matter accumulation,and promote yield improvement,making it a more suitable potato cultivation pattern for the northern foot of the Yinshan Mountains in Inner Mongolia.关键词
