Abstract

Abstract: In order to improve the utilization rate of saline-alkali land and effectively increase the yield of potato in alkaline saline-alkali land, the experiment was carried out in alkaline saline-alkali land of Dongying City, Shandong Province, and six different cultivation 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 potato growth.

Key words: potato(Solanum tuberosum L.), cultivation mode, botanical trait, photosynthesis, yield, alkaline saline-alkali soil, Dongying City
