柑橘间作可降低土壤容重,提高土壤孔隙度和水分含量,进而改良土壤物理性质。
参考来源 - 柑橘间作生态系统的生理生态特性及效益分析The activity of protease and soil bulk density has positive correlation, the amount of microorganism、the other activity of enzyme and soil bulk density has minus correlation. Otherwise, the amount of microor-ganism、the activity of enzyme were positively correlated with soil nutrients.
5通过对土壤微生物量、土壤酶与土壤养分的相关性分析表明,本研究区域土壤微生物数量、土壤酶活性均与土壤pH呈负相关,除蛋白酶与容重呈正相关以外均与容重呈负相关,与土壤养分均呈正相关。
