摘要 针对北方农牧交错区饲料短缺和饲用作物种植模式单一的问题,本文研究了燕麦与箭筈豌豆间作对饲草产量及土壤生物学性状的影响。本研究选择内蒙古农牧交错区中部凉城县进行,试验设燕麦和箭筈豌豆按行播1:1、1:2、1:3、1:4、2:1、3:1、4:1,及燕麦和箭筈豌豆单作,共9个处理。结果表明:间作处理中箭筈豌豆与燕麦1:3处理饲草产量高于其他处理,增加饲草粗蛋白含量和粗脂肪含量,且粗蛋白含量的最大值出现在播种后80 d;土壤微生物量碳含量最高的处理是箭筈豌豆与燕麦1:3处理,播种后80 d和110 d较燕麦和箭筈豌豆间作分别提高了21.89%、18.11%和14.34%、39.03%。土壤微生物量氮含量最高的处理是箭筈豌豆与燕麦1:3处理,2015年和2016年较燕麦和箭筈豌豆间作分别提高了28.25%、39.87%和35.93%、35.48%。过氧化氢酶活性最高的处理是箭筈豌豆与燕麦1:2处理,2015年和2016年较燕麦和箭筈豌豆间作分别提高了12.59%、23.09%和12.59%、12.17%,D:Y=1:3处理次之。土壤蔗糖酶活性较高的处理是箭筈豌豆与燕麦1:3处理,较燕麦和箭筈豌豆单作提高了12.83%、8.8%和4.44%、14.91%,箭筈豌豆与燕麦1:3处理的碱性磷酸酶活性最高,2 a分别较燕麦和箭筈豌豆单作提高了13.71%、0.03%和9.75%、7.12%。综合以上指标,箭筈豌豆与燕麦1:3处理产量、品种较好,土壤微生物量碳、氮最高,蔗糖酶和碱性磷酸酶活性最强,更适合在农牧交错区推广。 For the north farming-pastoral zone of feed shortage and forage crop planting patterns of a single problem,this paper studies the oat intercropping with common vetch on forage yield and the influence of soil biological properties.This study choose the farming-pastoral zone in Inner Mongolia middle Liangcheng,oats and common vetch test be sowing 1:1,1:2 and 1:3,1:4,2:1,3:1 and 4:1,and oats and common vetch monoculture,a total of nine.The results showed that the intercropping in processing the common vetch and oats 1:3 processing forage yield is higher than other processing,increase forage grass,crude protein and crude fat content and protein content of maximum value appeared in the 80 days after sowing;Soil microbial biomass carbon content of the highest treatment is the common vetch and oats 1:3,80 d and 110 d after planting oats and common vetch intercropping increased by 21.89%,18.11% and 14.34% and 18.11% respectively.The highest content of soil microbial biomass nitrogen treatment is the common vetch and oats 1:3,2015 and 2016 the oats and common vetch intercropping increased by 28.25%,39.87% and 35.93% and 39.87% respectively.Hydrogen peroxide enzyme activity of the highest treatment is the common vetch and oats 1:2,2015 and 2016 the oats and common vetch intercropping increased by 12.59%,23.09% and 23.09%,respectively,12.59%,D:Y=1:3 processing times.Soil invertase activity higher treatment is the common vetch and oats 1:3,the oats and common vetch was increased by 12.83%,8.8% and 8.8%,14.91%,and the common vetch and oats 1:3 treatment of alkaline phosphatase activity,two years were more oats and common vetch was increased by 13.71%,0.03% and 9.75%,0.03%.Comprehensive above index,the common vetch and oats 1:3 processing production,better varieties,the highest soil microbial biomass carbon,nitrogen,invertase and alkaline phosphatase activity,the strongest more suitable in the farming-pastoral zone of promotion.
