Abstract:
In order to understand the effects of different cultivation patterns on field temperature,biological traits and yield of potato in Tibet Plateau,we conducted a field experiment including following treatments:film mulching,adding straw,straw plus film mulching,and conventional planting as the control.The results showed that,in the early stages of potato growth,the average soil temperature was in an order of straw plus film mulching > film mulching > adding straw > CK.The plant height and stem thickness in treatment 3 were significantly greater than those of other treatments,increasing by 1.9%~39.6% and 13.7%~22.6%,respectively.The yield of treatment 3,treatment 1 and treatment 2 reached 44 022 kg·hm
-2,39 490 kg·hm
-2,and 22 211 kg·hm
-2,which was 109%,87.2% and 5.3% higher,than that of CK (21 091 kg·hm
-2).Therefore,adding straw and film mulching cultivation pattern would significantly improve the soil temperature,plant growth and yield of potato.
