摘　　要：本文研究了田间栽培条件下,3种果蔗-花生间作处理[1行果蔗间种2行花生(T2)、1行果蔗间种1行花生(T1)、果蔗单种(T0)]对果蔗、花生产量和种植前后土壤理化性状的影响,并对不同间种处理的经济效益、土地当量比进行分析。结果表明:与T0相比,T2、T1间种处理对果蔗、花生产量构成因素和单产均无显著影响。比较种植前和收获后土壤理化指标,T2和T1间种处理,均显著增加了土壤有机质和土壤碱解N含量并降低了土壤速效钾含量,T2间种处理效果更为明显。通过对3种间种处理的经济效益分析,与T0相比较,T2和T1 2种间种处理均能显著地增加单位面积的土地收益,土地当量比分别为1.94和1.72,提高了土地利用率;其中T2处理间种优势更加明显。并通过经济效益构成因素的相关分析,进一步明确了果蔗间种花生虽然部分增加种植成本,但能提高总产值和经济效益。综上所述,在3种间种处理中,1行果蔗间种2行花生(T2)处理对土壤影响较小,果蔗、花生产量和土地利用率、经济效益较高的间种方式。A one-factor field experiment of randomized block design was carried out to investigate the yield,economic benefit of chewing cane and peanut,as well as the soil physicochemical properties before planting(BP)and after harvest(AH)under different chewing cane–peanut intercropping treatments.Three intercropping treatments including chewing cane–peanut(1(25)2)intercropping(T2),chewing cane–peanut(1(25)1)intercropping(T1)and chewing cane mono-cropping(T0)were designed.Compared with T0,chewing cane–peanut intercropping patterns(T2 and T1)had no significant effect on the agronomic traits yield of chewing cane and peanut.Analysis results on the soil physicochemical index before planting(BP)and after harvest(AH)indicated that the chewing cane–peanut intercropping patterns could significantly increase soil organic matter and soil available nitrogen contents,but decrease soil available potassium contents,and the effect of T2 was more obvious than that of T1.The economic benefit of chewing cane–peanut intercropping patterns could significantly increase the total output and economic benefit.The benefits of chewing cane–peanut(1(25)2)intercropping(T2)was significantly higher than that of chewing cane–peanut(1(25)1)intercropping(T1).The land equivalent ratio(LER)of chewing cane–peanut intercropping patterns of T2 and T1 was 1.94 and 1.72,respectively.It is suggested that LER of chewing cane–peanut intercropping patterns was significantly higher than that of T0.The correlation analysis of output,cost and profit among the three chewing cane–peanut intercropping patterns showed that chewing cane–peanut intercropping partly increased planting cost,but significantly enhanced the gross output and profit.In conclusion,chewing cane–peanut(1(25)2)intercropping(T2)had minimal impact on the yield of chewing cane and peanut,and soil physicochemical properties,and also the best economic benefit among the treatments.
