摘要
为研究小麦豌豆套作对土壤养分含量及小麦产量的影响,试验设小麦豌豆套作6个处理和小麦单作2个处理,测定小麦产量和不同生育时期的土壤养分含量。结果表明,小麦豌豆套作相比小麦单作提高了土壤中的全氮、全磷、全钾、有机质含量和小麦产量;到成熟期,小麦24粒、豌豆15粒套作处理(W2P3)各项指标的达到最大,其产量是3181.38 kg/hm2。从土壤养分和小麦理论产量的相关性分析得出,小麦越冬期和拔节期的土壤全氮含量、成熟期全磷含量均与产量呈显著正相关。小麦与豌豆套作处理改善了土壤养分,从而提高了产量,且以W2P3处理效果最佳。
To study the effect of wheat-pea intercropping on soil nutrient content and wheat yield,six wheat-pea intercropping treatments and two wheat-single sowing treatments were set up,and the yield and soil nutrient content at different growth stages were measured.The results showed that the content of total nitrogen,total phosphorus,total potassium,organic matter in the soil and wheat yield wheat-pea intercropping were higher than that of wheat-single sowing.At maturity,W2P3(24∶15 sowing quantity of wheat and pea)had the highest yield of 3181.38 kg/hm2.In addition,from the correlation analysis of soil nutrient and wheat theoretical yield,the total nitrogen content of soil in overwintering period and jointing period,and total phosphorus content of soil in mature period were all significant positive correlation with the wheat yield.Therefore,the intercropping of wheat and pea improved soil nutrients,thus increased the yield,and W2P3 treatment was the best.
