Comparison of Two-film and Three-film Mulching Cultivation Patterns of Spring Potato in Changli County
Comparative experiments of two-film and three-film cultivation patterns were carried out in Changli County,Qinhuangdao City,in 2021,2022 and 2023,respectively,in order to compare the advantages and disadvan-tages of different cultivation patterns for film-covered potatoes in the two-cropping area of Changli County.Comprehen-sive analyses were conducted on the phenological stage,biological traits,and economic traits under the two cultivation patterns.No significant difference was found in disease occurrence between the two patterns.However,the growth period of the three-film mulching pattern was advanced by 5-6 days compared to the two-film pattern.Additionally,the yield increased by 11.6%-16.3%,with the increase of economic benefits ranging from 11.7%to 21.8%.The three-film cover pattern proves to be advantageous for promotion and demonstration in Changli County.
