内蒙古北部丘陵区,通过三年不同培肥制的研究表明,压内毛叶苕和豌豆茬籽实产量与连作和休闲区有显著差异。压内毛叶苕在轮作周期中硝酸态氮、铵态氪、速效磷较连作区和休闲区有明显增加。豌豆茬提供硝酸态氮和铵态氮与压内毛叶苕无明显差异。速效磷提供能力较差。有机质分析结果,各处理间三年的有机质累积量没有明显差异。对前两年资料统计表明,压内毛叶苕有机质累积量较其余处理有显著增加;土壤水分分析结果,后两年内以压内毛叶苕贮水量最低,休闲最高。第2年末100cm土壤中相差60.5mm,第3年春仍保持这一趋势,年末各处理持平。
In the northern hilly area of Inner Mongolia, the results of three years of different fertilization studies showed that there was a significant difference in seed yield between the leaves and the pea stubble in continuous cropping and recreation areas. Within the rotation cycle, the contents of nitrate nitrogen, ammonium krypton and available phosphorus in the inner leaves were significantly higher than those in the continuous cropping and recreation areas. Pea stubble provides nitrate nitrogen and ammonium nitrogen is no significant difference with the pressure inside the leaves. Available phosphorus provides less well. Organic matter analysis results, three years between the treatment of organic matter accumulation no significant difference. The data statistics of the previous two years showed that the organic matter accumulation in the leaves was significantly increased compared with the other treatments. The results of soil moisture analysis indicated that the water content of leaves was the lowest in the last two years and the highest in leisure. At the end of the second year, there was a difference of 60.5mm in 100cm soil. The third spring maintained the trend, and the treatments were the same at the end of the year.
