摘要
试验研究了不同复种方式对土壤养分的影响。结果表明,经过一个生长季节后,随着时间的推进,复种豌豆、燕麦后土壤中有机质、全氮、土壤碱解氮、有效磷的质量分数均有增加趋势;复种后土壤全钾、速效钾的质量分数、pH值呈下降趋势。本试验通过研究不同复种方式对土壤养分的影响,旨在为合理复种提供科学依据。
The effects of different multiple cropping methods on soil nutrients were studied.The results showed that after one growing season,with the advancement of time,the contents of organic matter,total nitrogen,soil alkali-hydrolyzed nitrogen and available phosphorus in the soil had increased after multiple cropping of peas and oats all;Potassium content and pH showed a downward trend.This experiment aims to provide a scientific basis for rational multiple cropping by studying the effects of different multiple cropping methods on soil nutrients.
