不同栽培模式下东营市碱性盐碱地马铃薯光合作用及产量表现OA

In order to improve the utilization rate of saline-alkali land and effectively increase the yield of potato in alkaline saline-al-kali land,the experiment was carried out in alkaline saline-alkali land of Dongying City,Shandong Province,and six different cultiva-tion modes were adopted to investigate their effects on botanical traits,photosynthesis and yield of potato.The results showed that the treatment of sowing with a furrow opening of 10 cm+drip irrigation+film mulching+whole tuber planting had the best comprehensive performance,exhibiting the earliest emergence time,the highest emergence rate and yield,and the strongest photosynthetic capacity,with a converted yield of 34 660 kg/hm2.The second-best performance was observed in the treatment of flat sowing+40 cm-high ridge+drip irrigation+plastic film mulching+whole tuber planting treatment,with a converted yield of 34 589 kg/hm2.This showed that in the saline-alkali soil environment,the whole potato sowing,drip irrigation,and film mulching had a prominent role in promoting pota-to growth.
