摘要
为了探讨不同灌溉方式对木薯产量和土壤理化性状的影响,以木薯品种‘新选048’为供试品种,采用微滴灌和微喷灌两种不同灌溉方式,研究木薯不同灌溉方式对产量和土壤理化性状的影响。结果表明,微喷灌对改善土壤化性状,提高木薯产量效果最好,其次是喷灌。微滴灌木薯产量比对照增产60.64%,土壤孔隙度提高10.62%,土壤速效氮增加29.00%,速效磷增加147.93%,速效钾增加5.49%。可见,微滴灌对改善土壤通气性,增加土壤有效养分,提高木薯产量有重要作用。
The effects of two different irrigation ways were studied with cassava cultivar ＇Xinxuan 048＇ on cassava yield and soil physical and chemical properties in this experiment. The results showed that Micro-drip irrigation for improving soil properties, improve cassava yield was the best, followed by micro-irrigation. Compared with the control, the cassava yield, the soil porosity, the soil available nitrogen, available phosphorus and available potassium with micro-drip irrigation respectively increased 60.64%, 10.62%, 29.00%, 147.93% and 5.49%. It was showed that micro drip irrigation has an important role for improving soil physical and chemical properties, increasing soil available nutrients, and increasing cassava production.
